Nuclear Power Uprat e: Crystal River Nuclear Plant Assessment with Progress Energy and AREVA 

By Dean Murphy on Apr 30, 201 0

Upra tes of existing nu clear power plant s, as a part of the US Electric Industry ’s balan ced blend of clean, n ew 

generation, has the potential to increase electrical capacity by 1 5%-20%. This can be achiev ed by utilizing

Measurement Uncertaint y Recapture, Stretch and Extended Power Uprates. The Nuclear Energy Institute

docum ent, “ Roadmap for Power Uprate Program Dev elopment and Implementa tion,” (NEI 08-1 0 Rev 0 Ju ly 2009 )

provides a road m ap for fut ur e Power Upra te projects based on a collabora tiv e effort between t he US Nuclear

Industr y Utilities and Design/Manu factu rin g v endors. The gu idance was based on lessons learn ed and exam ples

provided by ut ilities and v endors ov er th e last decade of experience. Progress Energ y presented a ca se study on

Cry stal Riv er Nuclear Plant Margin Manag ement an d Lessons Learned durin g an NEI industry forum in Janu ary 

201 0. This case study ha s been rev am ped to incorpora te feedback requesting a dditional topics and an over v iew of 

the project plann ing process. Progress Energ y ha s par tner ed with A REVA an d Worley Parsons, the origina l OEMs for

the Nuclear Steam Supply Sy stem, Fuel, Safety Analy ses and Turbine Plant Sy stems. This collaborativ e effort sets

the stag e for futu re Progr ess Energ y and Industr y Extended Power Upra tes.

 

Cry stal Riv er successfully perform ed a Measurem ent Uncertainty Recaptur e (MUR) in Ja nua ry 2008  which y ielded

a 1 .6% power in crease. During t he Unit’s Steam Generat or Replacemen t Project in Fall 2009 , the Major Projects

org anization took adv ant age of the Extended Out age to replace the Station’s Electrical Genera tor and Exciter, w hich

included a horizontal m id section core ir on r eplacement . In addition, th e iso-pha se bus duct coolers wer e replaced.

Other Secondary plant m odifications were perform ed which in cluded increased secondar y side cooling h eat

excha nger s, pumps, and m otors. The Moistur e Separ ator Reheaters (MSR) wer e replaced in order to ha ndle the

incr eased load deman d. This modification also inclu ded im proved Chev ron design efficiency for additional m egaw att

recov ery . A n ew regenerativ e heat exchan ge system w as also installed to recov er reject heat from the MSR drains

and retur n it to the condensate sy stem.  

Modifications and equipm ent specificat ions are being genera ted for t he next phase which will support a react or

uprate of 1 5.5%. This is cur rent ly the larg est power u prate perform ed on a US PWR, and th e first exten ded power

uprate perform ed on a B&W designed reactor. The License Am endment Request has been com pleted and wil l be

submitted to the NR C la ter this y ear. Modifications for the u pcom ing out age in clude a Low Pressure Injection cr oss

tie to mit igat e Core flood line break peak clad tem peratu res, Hot Leg Injection to mit igat e boron precipitation an d

GSI 1 91 concerns for post accident precipitan ts, and a secondar y side Fast Cooldown Sy stem w hich will u tilize new 

atmospheric dump valves and control systems to reduce secondary side and subsequently primary side pressures.

This im proves High Pressure Injection response and prov ides for some core flood injection w hich helps to mit igat e

peak clad t emperat ur e incr ease and lower dose consequence for cer tain specific small break loss of coolant accidents.

 Addit ional secondary equ ipm ent is being u pgraded or repla ced includin g th e condensat e pu m ps an d m otors, booster

feedwater pumps and motors, main feedwater pumps, a bypass around the deaerator, and feedwater heaters.

In addition to the CR3 EPU, Progr ess Energ y is curr ently designin g an MUR upra te at t he Har ris Nuclear Plant an d a

tu rbine retr ofit at t he Robinson Plant. Th e Bru nswick un it ha s prev iously perform ed tw o power u prates, a 5.5%

Stretch Uprate in 1 99 5 and a 1 5% Extended Power uprat e in 2003. Progress Energy and their partners, AREVA an d

 Worl ey Par sons, welcome ben ch m ar ks, lessons lea rned, and an y other correspondence.

Progr ess Energy and AREVA will be presenting a n in-depth discussion regardin g the uprate project at Cry stal Riv er

at Nu clear Energy Insider’s Nuclear Power Uprate Conference (June 2 1 -22 , 2 01 0) in Washington DC. The

conference will br ing t ogeth er upra te specialists in order to discuss best pract ice regar ding upr ates and how to plan

and execut e successful power upr ate projects. More informa tion rega rding the conference can be foun d at

Ken Greenw ood, Project Mana ger, Major Projects & Plant Upgra des from A REVA a dded, “Power upra tes are

especially importan t t o the nuclear industry today as utilities search for w ay s to increase their baseload capacity 

 without m akin g th e sig nifica nt inv estm ent in buildin g a new pla nt . Th is confer ence w il l pr ov ide pa rticipa nts w it h

the inform ation they need to plan an d execute a successful upra te project based on experience from other upr ate

projects.”

Progr ess Energy and AREVA will be joined by other in dustry experts including r epresentat iv es from Exelon,

 Am erican Electr ic Power , En tergy , TVA , EPRI, URS, Westin gh ouse, GE Hita ch i, Bech tel, Shaw Group, ENERCON ,

Siemens and more.
