COVER STORY

8 License Renewal Revitalizes the Nuclear Industry

Following the NRC’s approval of 20-year license renewals for two

U.S. plants, about a third of the country’s nuclear reactors plan to

apply for renewal by 2003, extending nuclear’s franchise for power

production well into the new century.

Editorial

Regulatory approval of the first renewed operating

licenses for U.S. nuclear power plants has set the

stage for a new era—one that ensures a continu-

ing role for nuclear energy in preserving America’s en-

ergy security and resource diversity. This new era is a

direct result of the electric utility industry’s collabora-

tion with EPRI over the past 20 years to establish the

technical foundation for extended plant operation and

to incorporate life-cycle management methodology

into ongoing plant operations and maintenance. The

pioneering efforts of Constellation Energy’s Calvert

Cliffs plant and Duke Energy’s Oconee plant, whose

license renewal applications were approved by the

Nuclear Regulatory Commission earlier this year, bene-

fit the entire nuclear utility sector. These efforts have

also established reasonable costs and schedules for

renewal applications.

The successful launch of the nuclear plant license

renewal era clearly demonstrates the strategic value of

long-term R&D and highlights the importance of con-

tinued collaboration in the technical work required to

support extended plant operation over the next 30 to

40 years. EPRI initiated its license renewal work with

its nuclear utility members more than 20 years ago to

help ensure that this strategic option would be avail-

able when needed. As it turns out, the renewal option

has arrived in time to impact utility decision making in

the emerging deregulated, competitive electricity sup-

ply market.

License renewal provides ample time to address the

inevitable challenges for a commercial revival of nuclear

power as a strategically vital, economical, emissions-

and carbon-free energy source in the United States.

Nuclear plants have generated almost 25% of the nation’s

electricity through the first half of 2000. Nevertheless,

in the eyes of the public, there are open questions. For

example, the management of used fuel is an issue of

public concern. Nuclear plants have stored used fuel

safely on-site since the beginning of the nuclear era, but

we need to push ahead with the federal fuel repository

for long-term storage. Here again R&D has helped

resolve the technical questions.

Paralleling efforts to develop a spent-fuel repository

must be a major new initiative by utilities, reactor

vendors, and the government to reduce the capital cost

of future nuclear plants. Cost reductions beyond those

already made will be necessary if new nuclear capacity

is to be competitive with natural gas–fired combined-

cycle plants on the basis of current fuel prices. The

optimization of currently licensed passive and evolu-

tionary advanced light water reactor designs offers one

approach, and—when proven viable—smaller, modular

nuclear plants using high-temperature gas as a coolant

will offer another.

Many countries that have committed to reductions

in carbon dioxide emissions from fossil fuel combus-

tion will face enormous economic penalties if the nuclear

alternative is eliminated. The same may be true for the

United States if we do not fund the engineering devel-

opment required for a true renaissance of nuclear

power. A sustainable national energy future requires

solutions that meet our growing energy needs in a way

that is safe, reliable, and environmentally friendly.

Nuclear energy has all these attributes. It does not pol-

lute the air or water. Its fuel supply is plentiful, inex-

pensive, and secure. Nuclear energy helps preserve

scarce natural resources.

The American public increasingly recognizes the

importance of nuclear energy as part of our future energy

strategy. In order to maintain and enhance public sup-

port, the nuclear industry must continue to operate the

current reactor fleet safely and reliably and to invest in

technology advances. A robust national energy policy

and responsible stewardship of natural resources require

that we keep all our energy options open.

Decontamination Handbook

D econtamination has played a key role in reducing occupa-tional exposures to radiation at U.S. nuclear power plants

over the past decade. In this process, dilute chemical solvents areused to remove deposited radioactivity. EPRI has been at theforefront of developing decontamination solvents and helpingutilities implement plant demonstrations. Today’s challenges areto reduce the costs of decontamination activities and to minimize

the activities’ impact on the duration of plant outages. TheDecontamination Handbook compiles lessons learned fromsub- and full-system applications, as well as decontamina-tion after permanent plant shutdown. It covers dilute sol-vents, corrosion issues, the effects of coolant chemistry,recontamination rates, and waste disposal issues. Thehandbook synthesizes critical information to help utilitypersonnel plan quick, efficient decontamination activitiesthat meet plant-specific needs.

BWR Water Chemistry Guidelines—2000 Revision

The control of BWR water chemistry increases plant availability by reducing intergranular stress corrosion cracking (IGSCC) in

cooling-system piping and reactor internals. The latest revision of theBWR Water Chemistry Guidelines presents new information that plantchemistry personnel can use to develop proactive, plant-specific waterchemistry programs to minimize IGSCC, flow-accelerated corrosion,fuel performance degradation, and radiation buildup. Two EPRI re-search advisory committees revised the guidelinesin response to the discovery of IGSCC in the coreshrouds of several BWRs—a finding that suggestscracking may be present in other reactor internalcomponents as well. The recommendations foradjusting chemistry limits and implementingmore cost-effective monitoring are expected toimprove protection against materials and fuelproblems and reduce the risk of losing reactoroutput because of chemistry transients.� For more information, contact Chris Wood, [email protected],

Pinpointing Hot Spots in Combustion Turbine Blades

Some 75% of all new generating ca-pacity planned in the United States

over the next decade is expected to bebased on combustion turbines. As the useof these turbines increases, plant opera-tors are becoming acutely aware of themachines’ higher-than-projected operat-ing and maintenance expenses. In partic-ular, there is increasing concern about the replacement and other costs related tothe durability and performance of hot-section parts, which experience the great-est thermal stress. A grow-ing backlog of orders forthe latest combustion tur-bine models is adding tounit availability and main-tenance pressures.

In 1998, operators ofadvanced F-class combus-tion turbines reportedthat none of the first-rowblades in machines re-cently placed in operationhad lasted the expected24,000 hours before refur-bishment. Although theseverity and nature of theproblems varied, they in-volved machines from allmajor vendors. Concerns over commis-sioning delays, spiraling O&M costs, andfailures of advanced turbines have per-sisted into 2000.

“Striking parallels can be drawn be-tween the present combustion turbineboom and the introduction of a new gen-eration of steam turbines in the 1970s,”says Vis Viswanathan, an EPRI technicalfellow and senior manager for materialsapplications technology. “At that time, anunprecedented increase in the number ofsteam turbine units created an insatiabledemand for replacement parts to ensureunit availability to meet consumer elec-

tricity demand. The demand for replace-ment parts was exacerbated by infantmortality problems when reliable turbinemodels were scaled up beyond theirdesign-cycle capabilities and the knowl-edge base of field service personnel.” Thecosts and lost availability for power pro-duction associated with the steam turbineboom were documented in an EPRI sur-vey at the time.

In the current combustion turbineboom, EPRI’s goal is to reduce the life-cycle costs of hot-section components byat least one-third. This amounts to over$45 million for a single unit in either base-

load or cycling duty. Atwo-year EPRI initiativeon the life management ofhot-section components—aimed at providing theengineering knowledgeneeded by operators ofadvanced F-class ma-chines to retain effectivecontrol over replacementof the most expensiveparts—has produced anumber of key results atits midpoint. These in-clude a hot-section lifemanagement system forpredicting creep andfatigue damage. This sys-

tem can predict the location of thermalbarrier coating failure in first-row buckets,which are the most complex to analyze in terms of temperature and stress. Com-bining aerothermal and structural analy-ses with damage algorithms, the systemaccurately predicts blade temperature andstress distributions for both steady-stateand transient conditions.

The initial sponsors of the hot-sectioncomponents initiative chose the GeneralElectric Frame 7FA+ and Frame 9FA tur-bines as the prototype cases for validatingthe system’s first-row bucket predictionand simulation capabilities. A six-step val-

idation process included the use of air-flow tests, optical pyrometry measure-ments of surface temperatures, and metal-lographic analysis.

The analytical approach embodied inEPRI’s life management platform for hot-section parts offers companies a vendor-independent source of technical expertise.“We have the combination of capabilitiesnecessary for bringing the elements ofmaterials, design, and operation together,”says John Scheibel, EPRI’s area managerfor combustion turbines. “Through ad-vanced simulations, the life managementplatform provides the temperature andstress information required to determinethe life consumption of any operatingcycle. It’s a design tool for combustionturbine operators, who can benchmarktheir specific operating scenarios againstthe generic properties of the turbine man-ufacturer’s design.”

Another product of the initiative is theCOATLIFE code for estimating the re-maining life of thermal barrier coatings. A comprehensive handbook on the prop-erties of all bucket materials is expectedto be available by the end of this year, andguidelines for improved buckets and forreducing life-cycle costs will also be is-sued beginning around then.

Companies that operate combustionturbines and are concerned about escalat-ing parts costs and related durabilityissues are encouraged to join the EPRIhot-section component life managementprogram. Potential future work includesthe development of the hot-section lifemanagement system and COATLIFE intocontinuous, on-line monitoring tools. Thelife management approach could also beextended to other bucket rows and noz-zles in 7FA machines and to other F-classturbine models.� For more information, contact John

New Push for Sustainable Coal Power

A s noted in EPRI’s Electricity Tech-nology Roadmap, population growth

and efforts to raise the standard of livingfor billions of impoverished people areforecast to create a greater than fourfoldincrease in worldwide electricity demandby 2050. Meeting this projected demandwill require the equivalent of building anew 1000-MW power plant somewhere inthe world every two days for 50 years.Even with a dramatically greater use ofrenewable energy sources in the future,coal—the world’s most abundant fossilfuel—will continue to play a large role inmeeting the ever-growing demand forelectricity in this century. This is particu-larly true for developing countries likeChina and India that have large, indige-nous coal reserves.

To accelerate research on generatingelectricity from coal in ways that are more environmentally sustainable, EPRIhas launched the Global Coal Initiative, a series of major new technology devel-opment efforts for which broad-basedsupport is being solicited among thepower generation, coal mining, and coaltransportation industries. The new ini-tiative currently includes six programsaimed at mobilizing technology advancesfor coal-fired plants that would have vir-tually no air pollutant by-products andnegligible or no net emissions of carbondioxide, the chief greenhouse gas impli-cated in global warming. The programsaddress CO2 control options; ultrasuper-critical pulverized-coal plants; advancedhigh-efficiency plants based on integratedgasification–combined-cycle configurationsand pressurized and atmospheric fluidized-bed combustion configurations; plantsfueled by low-volatile coal; lignite-fueledplants; and real-options market analyses.

“It is imperative that we burn coal morecleanly and efficiently, with minimal CO2

emissions, to avoid the risk of global cli-mate change,” says Stephen Gehl, EPRI’sdirector of strategic technology and alli-ances. “The Global Coal Initiative willspearhead research on methods for keep-ing CO2 out of the atmosphere by seques-tering it in natural sinks or exhausted oilfields.”

Like the EPRI Electricity TechnologyRoadmap, the Global Coal Initiative isbeing developed in dialogue with inter-ested stakeholders worldwide: powerproducers, coal companies, railroads,equipment vendors, banks, governmentagencies, and research foundations. Earlyparticipants have an opportunity to helpshape the content of the initiative and to begin to receive products and servicesas soon as the end of this year.

Southern Company, one of the coun-try’s largest electric utilities, has joinedthe initiative under a program that isdeveloping real-options business modelsto help power producers evaluate technol-ogy investments in a deregulated marketwith fluctuating fuel and electricity prices.“EPRI’s Global Coal Initiative recognizesthat the future begins today, and it offerspractical strategies to keep coal a compet-itive performer in the changing energy

marketplace,” says Randall Rush, directorof Southern Company’s Power SystemsDevelopment Facility, an R&D center inWilsonville, Alabama, that EPRI has longcosponsored.

In the 1980s, EPRI led an internationalcollaboration of generating companiesand equipment suppliers in a broad effortto advance pulverized-coal technologies.The widely recognized initiative led to newmaterials and designs that shattered then-existing engineering barriers to higheroperating temperatures and pressures forthe more efficient burning of coal. “Onthe basis of stunning new advances inmaterials and design concepts, we areready to move ahead with the next phaseof this work,” says EPRI’s Tony Armor,technical executive and generation mar-ket segment director. “In combined-cycleoperation, ultrasupercritical pulverized-coal plants are capable of achieving wellover 50% efficiency, far exceeding currentplant performance levels.”� For more information, visit the EPRI Desti-

T h e S t o r y i n B r i e f

The operating licenses of approximately 10% of current U.S. nuclear reactors

are scheduled to expire by the end of 2010, an eventuality once seen as the beginning

of the end for the nuclear option in the United States. But well-maintained

nuclear power plants have demonstrated their capability for safe, reliable operation well

beyond their initial 40-year license term—a period based on amortization accounting

rather than inherent operational limitations. This year, more than two decades

of preparatory engineering and planning by nuclear utilities and EPRI have paid off in

the NRC’s approval of 20-year license renewals for two nuclear plants, effectively

extending nuclear’s franchise for power production well into the new century.

About one-third of the country’s 103 nuclear reactors plan to apply for renewal by 2003,

and most currently operating plants are expected to renew their licenses. With capital

costs for the plants largely paid for, the revitalized nuclear fleet will be

among the most competitive power generators available.

b y T a y l o r M o o r e

REMARKABLE MILESTONE has been reached bythe once-quiescent nuclear power sector of theU.S. electric utility industry with the recentregulatory approval of two plants for an addi-

tional 20 years of operation beyond theiroriginal 40-year license terms. The successful completion ofthe license renewal process by these pressurized water reac-tor (PWR) plants, together with the establishment of thetechnical and regulatory bases for their approval and ex-tended operation, represents the realization of a key long-standing goal of EPRI’s nuclear power program. That goal isto ensure that the 103 units of the U.S. reactor fleet remaindependable, profitable electricity generators well into thenew century.

The U.S. Nuclear Regulatory Commission approved re-newed licenses for Constellation Energy Group’s two-unit,1700-MW Calvert Cliffs plant in Maryland last March andfor Duke Energy Corporation’s three-unit, 2500-MW Oco-nee plant in South Carolina two months later. The com-mission’s actions were widely applauded.

“It was with intense pride that I received . . . the nation’sfirst renewed operating licenses for a nuclear power plant,”Constellation Chairman and CEO Christian Poindexter toldcompany shareholders last April. “The additional 20 years

of authorized operation will take us to the mid-2030s. Thematerial condition of the plant will soon be enhanced by asteam generator replacement project. And the expertise wehave in managing the aging process . . . will contribute to asolid base of generation for our merchant energy business.”Formerly operated by Constellation’s Baltimore Gas andElectric subsidiary, Calvert Cliffs is now part of Constella-tion Nuclear Services, a nonregulated generating subsidiary.

Commenting on Oconee’s renewed licenses, MichaelTuckman, executive vice president for nuclear generation atDuke Energy, said, “Twenty years of additional life for thisstation will serve our region very well.” He noted thatDuke’s extensive inspection, maintenance, and equipmentreplacement programs gave the utility confidence that “thestation will operate safely and reliably well into the twenty-first century.”

Joe Colvin, president and chief executive officer of theNuclear Energy Institute (NEI), the industry’s Washington-based policy organization, sees the recent renewal activity as a key enabler of a secure energy future. “The process forrenewing licenses at nuclear power plants ensures a contin-ued, reliable, clean supply of electricity to satisfy the in-creasing demands of the digital economy,” says Colvin.“There will be many more license renewals at other nuclear

plants, further demonstrating the viabilityof nuclear energy and its vital role inAmerica’s energy mix.”

Indeed, license renewal applicationshave already been submitted to the NRCby Entergy Corporation for the ArkansasNuclear One unit 1 (ANO-1) PWR and bySouthern Nuclear for the two units of itsHatch plant in Georgia, the first boilingwater reactors (BWRs) to apply. NEI saysthat the owners of about one-third of thecountry’s nuclear reactors intend to applyfor license renewal by 2003, and ulti-mately most plants are expected to renewtheir licenses.

“The NRC’s in-depth review, whichclosely examines the safety and environ-mental record of these facilities, providesa clearly marked path for other electricitycompanies pursuing license renewal,” saysColvin. “Clearly, the next chapter in ournation’s nuclear energy history is beingwritten, and it is full of promise.” EPRI

and the U.S. Department of Energy esti-mated in the late 1980s that the value of20 more years of operation at all unitscould be as much as $200 billion; more re-cent estimates by NEI range from $110 bil-lion to $180 billion. U.S. nuclear plantsrepresent a combined 103 GW of installedgenerating capacity (about 15% of total ca-pacity) and supply one-fifth of the coun-try’s electricity.

Laying the groundworkThe success of the Calvert Cliffs and Oco-nee applications is both the start of the eraof license renewal and the culmination oftwo decades of utility industry efforts.These efforts laid the technical and regula-tory groundwork and defined the engi-neering needed for extended operationsunder plant life-cycle management. Life-cycle programs focus on managing theaging of critical plant structures, systems,and components.

In coordination with other industry or-ganizations, EPRI played a key technicalsupport role for nuclear plant operatorsthroughout the evolution of NRC rulesgoverning license renewal. EPRI took thelead in developing a knowledge base onthe effects of aging on various materialsand plant systems. The results were pre-sented in a series of industry reports thatwere submitted to the NRC and that areextensively referenced by utilities in li-cense renewal applications.

“From the beginning, EPRI has been aninvaluable partner and a vital technical re-source in life-cycle management,” saysDuke’s Tuckman. “EPRI’s early leadershipset the stage for the technical work thathas evolved into license renewal. Its tech-nical expertise has helped resolve issuesand answer the hard questions that con-fronted the NRC and our industry. Thiscollaborative work has been essential inthe success of the first two applicants forlicense renewal.”

Pilot life extension studies conductedby EPRI for two other plants in the early1980s demonstrated the economic andtechnical feasibility of extended operation(see sidebar, p. 16). Subsequently, EPRI’songoing nuclear R&D program generatedvital data on the aging of various safety-related nuclear plant materials as newquestions about age-related degradationmechanisms—such as various forms ofcorrosion—arose. And much of the engi-neering work for the Calvert Cliffs andOconee license renewal applications wasmade available to other utilities as EPRItechnical reports. EPRI has provided thissustained support of its nuclear clientsover the past two decades for a modest cu-mulative investment of some $22 million,supplemented by $15 million in membercofunding.

“Even if the total amount spent by EPRIand the lead utility license renewal appli-cants for each reactor vendor design reaches$100 million in the course of making li-cense renewal happen, the money will havebeen astoundingly well spent,” says BarthDoroshuk, president and chief operatingofficer of Constellation Nuclear Servicesand the former manager for license re-newal at Calvert Cliffs. “The payback on

Nuclear utilities have expressed the intention to seek license renewal for about a third (greendots) of the country’s 103 power reactors by 2003. A renewal application can be submitted fora unit after 20 years of service up until 5 years before its current license expires.

the investment is almost immeasurable,considering the positive impact it willhave for the entire industry.”

The reason, Doroshuk explains, is thatnuclear license renewal has arrived in thenick of time to be a factor in critical utilitydecision making. The decisions will ad-dress how best to manage generating assetsduring industry restructuring and consol-idation and the emergence of deregulated,competitive wholesale—and eventually re-tail—electricity markets. Until only re-cently, uncertainties about NRC require-ments for license renewal, together withuncertainties about how past utility invest-ments in nuclear plants would be treatedby state regulatory commissions duringthe transition to deregulated markets, hadmany companies questioning their contin-ued involvement in nuclear generation.They were considering plant closures anddecommissioning or sale. Indeed, severalplants changed ownership in recent years—with the first few selling at bargain-basement prices—and several others havebeen shut down for decommissioning.

“The industry’s successful demonstrationof the license renewal option has broughtnew life into an industry that, as little asfive years ago, appeared headed toward in-

creased plant closures,” says John Carey,EPRI manager for life-cycle management.“The outlook has changed dramatically.”

Catalyzing a resurgenceTed Marston, EPRI’s chief nuclear officer,calls the change “a revitalization of indus-try psychology” and attributes it to severalfactors. “For one, the issue of strandedcosts has been resolved, at least in thosestates where deregulation and restructur-ing have already occurred. State commis-sions have put negotiated charges on con-sumers’ electric bills, spread over a numberof years, for recovering nuclear plant cap-ital investments.

“Meanwhile, the NRC has revised andclarified the license renewal rules, makingthat option more economical and practicalfor utilities to consider; now the regula-tory process overall is less prescriptive andbased more on safety performance. In ad-dition, utilities that continued to invest inmaintaining their nuclear plants are find-ing that the plants really are in very good

shape. Continuing consoli-dation among the nuclearutilities promises to furtherreduce operating and main-tenance costs. Achievingeven greater efficiencies inoperations and in equipmentand service purchases is crit-ical to the success of nuclearpower in the deregulatedmarketplace.”

Thanks to greater regula-tory certainty and to lower

O&M costs, the better-managed, better-performing nuclear units with little or noremaining debt are very economical gen-erators. They are some of the cheapest,potentially most lucrative assets availableat a time when the country’s electricitygenerating base is restructuring for retailprice competition. (It is also a time when,with very few new baseload power plantsof any type being built, capacity reservemargins are shrinking to dangerously lowlevels in some regions.) Citing productioncost data from McGraw-Hill’s Utility DataInstitute, NEI says 43 U.S. reactors gener-ate electricity for less than 2¢ per kilo-watthour. The average production cost ofU.S. nuclear plants is within one-tenth ofone cent per kilowatthour of that of coal-fired plants, the cheapest source of base-load generation.

Operating in deregulated, competitivemarkets gives nuclear plants the opportu-nity to profit most when spot market elec-tricity prices are highest—typically duringperiods of hot summer weather when the

In March, Constellation Energy’s twin-unit,1700-MW Calvert Cliffs plant on ChesapeakeBay in Maryland became the first U.S. nuclearplant to receive 20-year license renewalsfrom the NRC. Units 1 and 2 are now clearedto operate until 2034 and 2036, respectively.Constellation Chairman and CEO ChristianPoindexter joined the Calvert Cliffs staff incelebrating the successful pioneering of therenewal process.

electricity demand for air conditioning ishigh.

Several industry initiatives have con-tributed to the performance turnaround ofnuclear plants. For example, better plan-ning and management of refueling outageshave cut their median duration from 75.5days in 1990 to 39 days in 1999; the top-performing units refuel within 25days. The less time a plant is downfor refueling, the greater its produc-tivity. In 1998, 89 nuclear units hadcapacity factors above 70%, and 74of these had capacity factors above80%. The respective numbers in1990 were 56 and 31 units.

“Deregulation may turn out to bethe best thing to happen to nucleargeneration in the United States,”says Marston. “Utilities with well-run nuclear plants are keenly awareof the value of these plants in acompetitive market.”

U.S. nuclear plants also have sub-stantial environmental value, pro-ducing virtually no emissions. Ac-

cording to NEI, an equivalent amount ofcapacity fueled by coal, oil, or natural gaswould release some 133 million tons ofcarbon dioxide a year. DOE has acknowl-edged the importance of nuclear licenserenewal in helping the country limit thegrowth of carbon emissions from fossilfuel use. It says that a typical nuclear plantdisplaces about 1.2 million metric tons ofcarbon-equivalent greenhouse gases eachyear of operation.

Compared with any alternative for newor repowered fossil generating capacity,obtaining a nuclear plant license renewalhas a low direct cost, and that cost is ex-pected to get even lower. ConstellationEnergy says its 2500-page Calvert Cliffsrenewal application, which took nearly adecade of planning and preparation, costaround $19 million, or $11 per kilowatt.Duke Energy says the cost of preparing theapplication for its larger Oconee plant wasabout $12 million, or $4.73 per kilowatt. Asa result of standardization, future applica-tions beyond the first few of a specific reac-tor design are expected to cost much less.

But the cost of preparing a license re-newal application is only part of the calcu-lus. “License renewal is just the regulatoryticket to operate the plant for an addi-tional 20 years,” notes John Carey. “It cer-tainly gives a utility flexibility in strategicplanning, but profitable operation of the

plant will depend on its life-cyclemanagement program. How do yourun the plant to get the highest pro-duction? When is the best time torefurbish or replace components?How do you avoid failures at thelowest cost? How do you find sup-pliers for replacement parts? Theseare all part of life-cycle management,which EPRI has been working onin tandem with license renewal.”

As part of plant life-cycle man-agement, additional capital invest-ments may be needed to ensure

economical operation over the extendedlicense term, including replacement oflarge components or upgrading of key sys-tems. For example, Constellation Energyand Duke Energy plan to replace all thesteam generators over the next severalyears at Calvert Cliffs and Oconee at a costof over $300 million for each plant. In ad-dition, both companies are planning tospend a similar sum for other equipmentand system upgrades at the plants over thenext five to seven years.

“These plants are not unlike any largemanufacturing facility when it comes tomaking capital investments to ensure theirreliable and safe operation,” says Doroshukof Constellation Nuclear. “As long as aplant can continue to produce electricityand investments can be made to keep itsafe, reliable, and in compliance with reg-ulatory requirements, plant upgrades makesense. We’re not unlike other industries

The NRC approved Duke Energy’s licenserenewal application for its three-unit, 2500-MW Oconee plant on Lake Keowee in Seneca,South Carolina, in May. In planning for licenserenewal at Oconee, the company adopted acomprehensive life-cycle management ap-proach focused not only on extending opera-tion from 40 to 60 years but also on bene-fiting operations for the remainder of theplant’s original license term.

that compete on the basis of cost-effectiveoperation of facilities. The Calvert Cliffsand Oconee renewals and planned up-grades illustrate how license renewal andplant life management go hand in hand.”

With only a few years left on an oper-ating license, utilities would be reluctantto make substantial investments like the$300 million Constellation and Duke areeach planning to spend for new steamgenerators. But that amount is only a frac-tion of the projected value of Calvert Cliffsor Oconee over an extended operating life.Says Carey, “License renewal effectivelyminimizes the endgame effect of declininginvestment in a plant as it ages.”

Looking ahead with a new lease on lifeBy the end of this decade, it is expectedthat all the plants planning to apply for li-cense renewal will have done so and thatthe NRC will have reviewed and ruled oneach individual unit. Beyond that pointcomes the real work of life-cycle manage-ment for each plant.

According to Greg Robison, Duke En-ergy project manager for license renewal,planning for Oconee’s license renewal wasa strong motivator for taking a larger, life-cycle management, perspective. “We be-gan to think long ago about critical com-ponents in the plant—the pressure vesseland key piping and pumps. Over time werealized that life-cycle management ismultifaceted and not just about pieces ofhardware. We had to remind ourselves toback up and ask broader, longer-termquestions: How much are we spending onmaintenance? What kinds of things aregoing to develop as the plant gets older?What kinds of modernization are going tobe needed? When you do that, you go be-yond safety and reliability issues. That’swhere life-cycle management comes in—looking at the total plant to understandtechnically how it ages and to understandwhat it’s going to take financially to stay inbusiness.”

Looking five years out, says Robison,“we see deregulation coming, and we see acontinued need for the electric utility in-dustry to be able to manage the aging ofplant hardware and to be able to afford

plant retrofits, control systems upgrades,and the like. Because the U.S. nuclear plantfleet is not standardized, we need contin-ual dialogue to come up with solutionsthat work for each plant. EPRI provides aforum for having those dialogues, and wetry to take advantage of them as often aswe can.”

For Duke, every lesson learned from theexperience of relicensing Oconee is a les-son that can be applied several times again.The company is already working on li-cense renewal applications for its McGuireand Catawba plants. “We expect manycost elements to be less for McGuire andCatawba—certainly the technical develop-ment costs should be less. We’ve already

published a lot of work, much of whichwe can reuse, and EPRI has published alot. When we began work on the Oconeeapplication, we had plant-specific prob-lems. Now we have industry solutions thatcan be applied,” says Robison.

“The industry and the NRC are in theprocess of standardizing what we’ve learnedfrom the Calvert Cliffs and Oconee work,”Robison continues. “In considering the ag-ing of a piece of hardware, we know it’s aproduct of the materials, the environmentthe hardware is exposed to, and the loadsor stresses applied to it. That’s generallytrue regardless of the industry involved.Through its publications, EPRI has helpedus put into perspective the fact that the

Nuclear utilities have had great success in reducing the time that units are out of service forrefueling, with better outage planning and management cutting the median duration of re-fueling outages from 75.5 days in 1990 to 39 days in 1999. This marked improvement has been largely responsible for a steady increase in U.S. nuclear plant capacity factors in recentyears—to an average 85.5% in 1999.

In contrast to the 1980s, when increased regulatory requirements drove up nuclear O&M costssubstantially, the 1990s produced a clear decline in average production costs, thanks in part tomore-efficient refueling and lower forced-outage rates. The best-performing nuclear plantstoday generate electricity for less than 2¢ per kilowatthour, and the average production costfor all nuclear plants is within a fraction of a cent of that for coal-fired plants.

process is going to occur in every nuclearplant.

“We need to look at how we manage aparticular kind of aging and find a com-mon approach for doing it—like the EPRIwater chemistry guidelines we all use. Inthat case, EPRI’s work helped to standard-ize a plant programmatic solution thatprevents corrosion problems in piping sys-tems. We expect there will be other suchareas where commonality can be derivedfrom an EPRI effort—for ex-ample, the area of flow-acceler-ated corrosion.”

Returns on R&D investmentThe willingness of nuclear util-ities to support EPRI’s collabo-rative program has paid divi-dends over the near term—dividends that are expected tobe critically important for ex-tended operation.

“EPRI has developed manyprograms that have to be cred-ited for contributing to our li-cense renewal application,” saysChuck Pierce, license renewalproject manager at SouthernNuclear, which has submitted a renewalapplication for its Hatch BWR units to theNRC. “Without those programs havingbeen generically fleshed out by EPRI, wewould be having a much more difficulttime right now with license renewal.EPRI’s BWRVIP [BWR Vessel and InternalsProject] and the BWR water chemistryguidelines are particularly important. Wewill need those programs well into thefuture to continue to mitigate aging, par-ticularly as new issues arise.” (Earlier thisyear, the NRC approved two BWRVIPguideline reports for referencing in licenserenewal applications.)

On the basis of EPRI’s work demon-strating the benefits of life-cycle manage-ment programs, Southern Nuclear is con-sidering implementing its own program atHatch. EPRI recently published Southern’stime-limited aging analysis for the Hatchplant to benefit other BWR utilities con-sidering license renewal.

Preserving and updating the historicalbody of technical knowledge about aging

effects constitute an important role forEPRI, which has the expertise to evaluatenew information and developments. Anexample of this role cited by Pierce and byGarry Young, license renewal project man-ager for Entergy’s ANO-1, is the recent li-censing of a series of mechanical andstructural analytical tools developed bythe Babcock & Wilcox Owners Group.EPRI will maintain these tools and expandthem with information on other vendordesigns.

Says Young, “From my point of view,having these tools available through EPRIgives us the added benefit of input fromthe entire industry; everyone’s experiencewill be incorporated, making the toolsmore complete and useful to a wider vari-ety of plants. The analytical tools representa key product. When they were B&W’s,we used them in preparing our renewalapplication for ANO-1, and we expect torely on them in future license renewalprojects—for ANO-2 and all the other En-tergy nuclear plants.” Entergy Operations,

an Entergy subsidiary, operatesfive nuclear units in the com-pany’s four-state service area—the two ANO units, Grand Gulfin Mississippi, and River Bendand Waterford 3 in Louisiana.Another subsidiary, Entergy Nu-clear, acquired the Pilgrim plantin Massachusetts and, more re-cently, the Indian Point 3 and

Fitzpatrick units from the New YorkPower Authority.

Entergy submitted its license renewalapplication for ANO-1 in January 2000and is now fielding queries from the NRCstaff. Consistent with the experience at Cal-vert Cliffs and Oconee, Entergy anticipatesNRC approval by January 2002. The sameteam that prepared the ANO-1 renewal ap-plication will begin working around mid-2001 on the application for ANO-2, whichhas a different vendor design than ANO-1.Entergy hopes to submit the ANO-2 appli-cation around the third quarter of 2003.

“As the NRC reviews the ANO-1 appli-cation, we’re being asked about things likeenvironmentally assisted fatigue in reactorcooling system piping, an aging mecha-nism that is still a focus of research,” saysYoung. “That’s the kind of very technicalissue EPRI is helping the industry dealwith. Since we don’t have an expert on thatsubject in our company, we expect to de-pend on EPRI to help us evaluate the re-search data as it becomes available.”

Entergy submitted a license renewalapplication for unit 1 of its ArkansasNuclear One plant in Russellville in Feb-ruary 2000, and it has informed the NRCof its intent to apply for ANO unit 2 in2003 and for all its other nuclear plantsbetween 2003 and 2010. These actionsare in line with a growth strategy thecompany announced in 1998 that isbased on power generation—especiallyon the global development of merchantpower plants and on nuclear poweroperations and management.

A market for renewal servicesVirtually right out of the gate from theCalvert Cliffs and Oconee extended li-cense approvals, the successful applicantslaunched commercial ventures to markettheir license renewal experience and ex-pertise to other utilities.

Both Constellation Nuclear Services anda joint venture of Duke Engineering &Services (an independent affiliate of DukeEnergy) and Scientech (a nu-clear and industrial servicesfirm) are marketing themselvesas seasoned veterans of the rig-orous license renewal process.Both offer full-scope projectplanning and execution, frominitial plant strategy and deci-sion analysis to the completionof the renewal process, as wellas other strategic engineeringservices. Entergy Nuclear is an-other entrant in the field, hav-ing partnered with FramatomeTechnologies to offer license re-newal services and engineeringto U.S. plants. Other compa-nies also offer license renewaland life-cycle management ser-vices to nuclear utilities.

“These kinds of ventures in-dicate how rapidly license re-newal has matured into a com-mercial reality,” says EPRI’sCarey. The DE&S-Scientechteam says it contributed toeach of the four renewal appli-cations submitted to the NRCso far and is working with fiveother license renewal projectsthat expect to submit applica-tions over the next two years.And Doroshuk of Constella-tion Nuclear reports that hiscompany is working at almostevery U.S. nuclear utility sitepursuing license renewal, aswell as at nuclear plants in Ko-rea and Japan.

The engineering consultingservices of these ventures willcomplement, rather than com-pete with, EPRI’s core R&Dwork, says Doroshuk. “We en-

courage our clients to take maximum ad-vantage of the tools and products EPRI haspublished so that they don’t end up re-inventing the wheel. I see EPRI as a part-ner in license renewal. No company cando it all, even one like ours that has ex-perience in the license renewal business.There are a lot of organizations and com-panies involved in license renewal, andEPRI is one of them.”

Despite two successful license renewalapplications to date, “for anyone to thinkthat license renewal is now a breeze wouldbe a fatal mistake,” says Doroshuk. “It is afederal proceeding with many stakehold-ers involved, and it can be volatile. Ourindustry must pull together and get theproper resources in place to help every ap-plicant get through the process. I tell nu-clear service companies that want to get

involved in license renewal to concentrate on their corecompetencies, like equipmentupgrades, because now that li-censes are starting to be re-newed, we’re seeing signifi-cant capital investments beingmade again. We have to cheereach other on and work to-gether to make this a growthindustry again. The cost offailure to the nation’s economyis enormous.”

Competition’s challenge and opportunityThe positive shift in industrypsychology triggered by theadvent of the plant license re-newal era has inevitably en-couraged some observers andadvocates for the industry toconceptually extrapolate fromrevitalization to rebirth fornuclear power in the UnitedStates. A few utility executiveshave even been heard to sug-gest that an order for a newnuclear generating unit couldbe placed in the foreseeable fu-ture—something that has nothappened in nearly a quartercentury.

Those executives would un-doubtedly hasten to add thatthey are not ready to act justyet. Through most of the nextdecade, nuclear utilities mayhave their plates full obtaininglicense renewals and makingthe investments and upgradesthat will position their exist-ing workhorse plants as com-petitive generators for an ad-

Fall 2000 EPRI JOURNAL 15

In the past decade, EPRI has produced a wealth of information on nu-clear plant license renewal and life-cycle management, including about30 reports on the successful Calvert Cliffs program and 10 license re-newal industry reports. Key examples are listed here. These and otherreports can be obtained from EPRI Customer Service, [email protected],800-313-3774, or from John Carey, [email protected], 650-855-2105.

The earliest documented study ofextended nuclear power plant op-eration was initiated by EPRI in

1978 and published the following year.That planning study examined the techni-cal and economic feasibility of operatingnuclear plants beyond their nominal 30-to 40-year life as an alternative to decom-missioning.

No significant technical obstacles thatwould preclude life extension were identi-fied by that or subsequent early studies,but potential long-term aging issues wereidentified. These included reactor pressurevessel integrity, the potential need to re-place electrical cable, and the potentialdeterioration of critical concrete struc-tures like the containment structure.The studies concluded that, comparedwith new construction, extended oper-ation was economically attractive evenwith large expenditures and substantialoutages for plant refurbishment. Thestudies also pointed out that plantswere experiencing a loss of licensedoperating time because licenses weredated from the time a construction per-mit was issued rather than from theplant’s completion date. The resultingcorrective regulatory action added anaverage of six to seven years to plants’operating life.

1983–1987: Pilot plant studiesDetailed pilot plant life extension stud-ies of the Monticello BWR plant ofNorthern States Power and the SurryPWR plant of Dominion Resourcesfound no insurmountable technical issuesfor extended operation. The studies alsodemonstrated favorable economics, with afour-to-one ratio of benefits to costs. Theyconcluded that the costs of managing theaging of critical components, includingcomponent replacement, would be thedetermining factor of a project’s economicfeasibility.

By providing an industry model forother plant-specific life extension studies,the EPRI work resulted in substantially in-creased industry interest in life extension.

The NRC, meanwhile, began an aging pro-gram for nuclear plant electrical compo-nents, which was later expanded to covermechanical and structural components.

1988–1991: Lead plant projects and NRC rulesIn response to industry requests, the NRCbegan to establish criteria for nuclear plantrelicensing in the late 1980s. EPRI initi-ated lead plant license renewal projects atMonticello and Yankee Rowe and helpedshape draft NRC documents published inthose years. EPRI also completed 10 li-

cense renewal industry reports for majorsystems, structures, and components. Thereports provided the basic model for allsubsequent reviews of aging management.It was found that most aging issues werealready managed under existing plant pro-grams. A small number of component ag-ing effects issues were identified thatwould require additional managementduring the extended license term. The reg-ulatory basis for license renewal was es-tablished as the current license basis,which must be maintained during the re-

newal term through adequate aging man-agement for components and structures.

Nuclear plant economics were rapidlychanging during this period, with O&Mcosts increasing substantially. The criticaleconomic test for nuclear license renewalwas not whether it would be superior tonew fossil plant construction, but whethernuclear plant production costs would becompetitive in an unregulated electricitymarket during the renewal term.

Economic and regulatory issues led tothe termination of the Monticello and Yan-kee Rowe projects and to the closure of

Yankee Rowe. Although they did notachieve license renewal, the lead plantprojects helped define the technicalscope of license renewal and acceler-ated the NRC’s establishment of reli-censing criteria.

1991–1998: Calvert Cliffs and OconeeThe NRC’s initial license renewal rule(10 CFR 54) was issued in 1991. EPRIand Baltimore Gas and Electric (BGE)launched a life-cycle management pro-gram at Calvert Cliffs to develop a long-term strategic plan. Economic analysesassumed deregulation and demonstratedthat Calvert Cliffs could be competitive.Duke Power initiated a similar licenserenewal effort for Oconee. Three own-ers group programs were begun by util-ities owning Babcock & Wilcox PWRs,Westinghouse PWRs, and General Elec-tric BWRs.

EPRI funded license renewal projectsat Calvert Cliffs and with the B&W Own-ers Group—projects that attempted to im-plement the requirements of 10 CFR 54 onselected systems and components. Thework demonstrated a need to revise the li-cense renewal rule to allow more credit fornormal maintenance. Primarily as a resultof these studies, the NRC amended therule in 1995, limiting the review scope andallowing credit for ongoing managementof the aging of active components. The re-visions also eliminated reference to age-related degradation unique to license re-

ditional 20 years. It is more than a lit-tle ironic, however, that the tonic for nu-clear power, viewed by some as emblem-atic of regulated monopolies that makechoices insulated from real-world eco-nomics, would turn out to be the prospectof unbridled competition in a deregulatedmarket. And the patient appears to thriveon the tonic.

“It’s taken the industry 22 years to getfully into the business of license renewaland aging management, but from my per-spective, the money invested in the neces-sary R&D to reach this point has been wellworth it,” says Duke’s Robison. “We neverwould have gotten here if it had not beenfor EPRI continually focusing on the vision,saying that there has got to be a viable,standard way for utility people to thinkabout how to take care of these plants andbe able to renew the licenses.”

“If you operate nuclear plants well,keep them in good running condition, andkeep their capacity factors high, deregula-tion and license renewal provide the op-portunity to make more money fromthem,” says Entergy’s Young. “Deregulationmakes the plants more financially attrac-tive than they would be otherwise. It en-ables a well-run nuclear plant to get into aposition to add to the value of a company.”

Concludes Doroshuk of Constellation

Nuclear, “The industry will go through aperiod of major change in the next 10years. There will be more consolidation ofnuclear operating companies. We see de-regulation and restructuring happening,but inconsistently from state to state. Weall must continue to realize that safety,quality, and reliable operation of theseplants are what got us here today and whatwill get us there tomorrow. So we need tocontinue to meet the expectations of theNRC; to continue to meet the responsibil-ities placed on us by the public and our lo-cal communities to operate these plantssafely; and to team together to meet thechallenges of consolidation, of deregula-tion, and of long-term plant operation. Ithink if we can do that, then nuclear en-ergy as a source of electricity will continueto be part of a diverse fuel mix in theUnited States.” �

Southern Nuclear and Entergy initi-ated license renewal programs for theHatch plant and Arkansas Nuclear Oneunit 1, respectively, and several otherutilities began planning studies. TheNRC published its draft license renewalstandard review plan and its generic en-vironmental impact statement. The lat-ter document substantially limited thenumber of environmental issues thatmust be considered on a plant-specificbasis.

BGE and Duke Power submitted thefirst license renewal applications for Cal-vert Cliffs and Oconee, respectively, in1998. The submittals attracted increasedutility interest and led to the formationof license renewal programs for a num-ber of other nuclear plants.

1999–2004: StandardizationThe NRC set and met an aggressiveschedule (approximately 24 months) forreviewing the Calvert Cliffs and Oconeeplant license renewal applications. Cal-vert Cliffs received a 20-year license re-newal in March 2000 and was followedby Oconee in May 2000; the operatingterm of each plant was thus extended tothe mid-2030s.

EPRI, industry, and NRC efforts arenow focused on standardizing the licenserenewal process and on substantially re-ducing both the cost of preparing a re-newal application and the time requiredfor NRC review. License renewal appli-cations are currently being prepared forapproximately 20 nuclear units. The goalfor application preparation costs is to re-duce them to around $3 million by 2004.NRC reviews will probably take 12–18months, with the length dictated pri-marily by the public process required forreviewing the supplemental environmen-tal impact statement for plant-specific li-cense renewal. �

GasVue Helps WAPA BringSF6 Leaks to Light

The GasVue camera for locating leaksof sulfur hexafluoride (SF6) dielec-

tric is helping the Western Area PowerAdministration minimize releases of that greenhouse gas from transmissionequipment for a far-flung network of fed-eral hydroelectric plants. WAPA recentlylaunched an aggressive campaign to track

down SF6 leaks in its nearly 17,000-mile(27,000-km) high-voltage system, whichtransmits more than 10 GW of power fromhydro plants in 15 central and westernstates. One of four federal power market-ing agencies, WAPA has among its whole-sale customers rural cooperatives, munici-palities, Native American tribes, and othernonprofit entities.

SF6 has a unique combination of chemi-cal and physical properties that makes itideal as an insulator in circuit breakersand other high-voltage switchgear; how-ever, its efficient absorption of infraredenergy and long atmospheric lifetime alsomake it a potent greenhouse gas, one ofsix targeted by international agreementfor emissions reduction. The U.S. Envi-ronmental Protection Agency has calledfor voluntary participation by electric util-

ities and other industries in efforts toreduce, inventory, and track SF6 emis-sions. WAPA’s campaign seeks not only to detect and repair leaking equipmentbut also to modify maintenance practicesin order to minimize releases.

At the heart of WAPA’s fast-track effortis the GasVue camera, a state-of-the-artbackscattering laser-based system devel-oped with EPRI support by Laser ImagingSystems of Punta Gorda, Florida. The

camera combines a carbondioxide laser (tuned to aninfrared absorption wave-length of SF6) with an elec-tronic infrared imaging sys-tem. As leaking SF6 absorbssome of the laser light thatbounces off a background sur-face, an image of the invisiblegas is produced on the sys-tem’s video display.

“We estimate that we havenearly 750 pieces of SF6-filledequipment and about 200,000

pounds [91,000 kg] of the gas in place,”says Dave Pearson, an environmental pro-tection specialist at WAPA and the coman-ager of its SF6 program. “Finding a cost-effective way to locate leaks was critical tothe program’s success.”

The GasVue camera is proving its worthin the field, thanks to its ability to operate

on energized equipment, says programcomanager and electrical engineer LarryRomero. “It’s an effective maintenancetool because it quickly and accurately lo-cates SF6 leaks, some as small as 2 pounds[0.9 kg] a year, on energized equipment atdistances of up to 60 feet [18 m].” Withtraditional leak detection methods—halo-gen detectors and soapy water—equip-ment must be deenergized.

WAPA’s program incorporates emis-sions training into routine maintenancetraining, stressing the use of emissionstracking data in predicting when andwhere leaks will develop so that mainte-nance schedules can be optimized. Othergoals include preventing equipment fail-ures, reducing SF6 replacement costs, andimproving personnel safety.

WAPA estimates the program’s startupcosts at $65,000 to $80,000, dependingon the level of reduction in SF6 replace-ment expenditures. Annual program costsare estimated at $40,000. “That’s roughly80% less than costs estimated using EPA

guidelines,” notesPearson. “We thinkthat’s good business.”

Inspections with the GasVue camera ateight substations inCalifornia, Colorado,Nebraska, and Wyo-ming have revealedonly minimal leaks—“indicating that ourcurrent maintenancepractices for SF6-filledequipment are effec-tive,” says Romero.

“However, as the cost of SF6 increases andthe emphasis on greenhouse gas emis-sions reduction continues, the need toimprove how we manage this gas willbecome more critical.”

HTS Cable Project, Wire Manufacturing Advance

D etroit Edison has been recognized by the U.S. Department of Energy

for its leadership in demonstrating newtechnology for high-temperature super-conducting (HTS) power cable in a proj-ect supported by DOE and EPRI. DanReicher, assistant secretary of energy, said at a ceremony last spring that thecompany is playing a key role in advanc-ing the world’s first installation of HTScable on an operating utility system. Suchcable could enable utilities to keep pacewith electricity demand growth in revital-ized downtown areas like Detroit’s whileminimizing infrastructure disruption.

Presenting Detroit Edison officials witha commemorative plaque at the ceremonynear the utility’s Frisbie substation, wherethe 24-kV cable will be installed earlynext year, Reicher applauded the utility’scommitment to the demonstration proj-ect. Noting Detroit Edison’s various effortsto develop clean energy technologies—including fuel cells, landfill gas plants,and solar photovoltaics—and its plantingof millions of trees through the govern-ment’s Climate Challenge program, theassistant energy secretary called the HTScable project “the icing on the cake.”

“Because it is further down the roadtechnologically, it requires a bigger com-mitment for a utility to step up and say‘we are going to do this,’” Reicher said.

But with a utility like Detroit Edison step-ping up and working in partnership withthe government and various companies,he went on, “we actually think we aregoing to move this quickly into use, andthe American people are going to be thebeneficiaries.”

HTS cable, which is supercooled tomake it more efficient than conventionalcable, promises to provide greater systemreliability during periods of high electric-ity use. Learning how such new technol-ogy can work for both a utility and its cus-tomers is an important reason that DetroitEdison is “an eager participant in cutting-edge research and development projectslike this one,” said Robert J. Buckler, pres-ident of DTE Energy Distribution.

Among the other participants in theDetroit demonstration are Pirelli Cablesand Systems, American SuperconductorCorporation (ASC), and Lotepro Corpo-ration. The project is a follow-on effort tothe successful development and testing ofa laboratory prototype HTS cable by Pirelliand EPRI in 1998.

Meanwhile, ASC continues to reportprogress in the commercial developmentof HTS power technology based on itsfirst-generation high-performance wire,which, it says, carries over 100 times theelectric current of copper wire with thesame dimensions. The company recentlyannounced plans for a greenfield wire-manufacturing plant in Massachusettsthat is expected to be in full production(10,000 km per year) in early 2002.

In addition, ASC has invested in thedevelopment of second-generation HTSwire technology in an alliance with EPRIover the past four years. Under thisalliance, ASC has exclusive rights to allEPRI technology on second-generationwire. The company has also obtainedlicenses for key components of second-generation wire technology from OakRidge National Laboratory and the Massa-chusetts Institute of Technology. Theselicenses add to the patents and patent ap-plications generated in ASC’s own labora-tories. The new licensing agreement withOak Ridge is accompanied by an agree-ment on wire R&D that ASC will fund.

According to CEO Greg Yurek, ASC hasachieved world-leading laboratory resultsin short samples with its proprietary tech-nology for low-cost, second-generationHTS wire. “This technology puts us on apath to beat the price-performance char-acteristics of copper wire,” he says.

Adds Paul Grant, an executive scientistat EPRI, “ASC has been successful indeveloping what we believe to be themost commercially advantageous route tomanufacturing second-generation HTSwire, which will open an even bigger market for superconducting products inthe future.” The company plans to fur-ther improve the performance of second-generation wire and to scale up to high-volume production of long-length wiresin the next three to five years.� For more information, contact Paul Grant,
