I. INTR DUCTION AND SUMMARY

A periodic Type "A" Integrat'ed Leakage Rate Test (ILRT) was successfully conducted on the

primary containment structure of the Florida Power & Light Company St. Lucie Plant Unit

No. 1 Pressurized Water Reactor. This test was performed at fullpressure in accordance with

the facility Technical Specifications.

This ILRT was performed using the "Absolute Method" of testing in accordance with the Code

of Federal Regulations, Title 10, Part 50, Appendix J, "Primary Containment Leakage Testing

for Water-Cooled Power Reactors," in accordance with ANSI N45.4 - 1972, American National

Standard, "Leakage Rate Testing of Containment Structures for Nuclear Reactors," and the

methodology and calculational requirements of Topical Report BN-TOP-1, Revision 1, "Testing

Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear

Power Plants." The ILRT was performed at a pressure in excess of the calculated peak

containment internal pressure related to the design basis accident as specified in the Final Safety

Analysis Report (FSAR) and the Technical Specifications.

This report describes and presents the results of this periodic Type "A" leakage rate testing,

including the supplemental Controlled Leakage Rate Test (CLRT) method utilized for

verification. In addition, Florida Power &Light Company performs Types "B" and "C" testing

in accordance with the requirements of 10CFR50, Appendix J, and the Technical Specifications.

The results of types "B" and "C" testing performed since the last ILRT are provided in this

report.

The resulting reported "as-found" Type "A" containment leakage at .319 percent of theI

containment mass per day. This value includes the difference between the as-found and as-left

minimum pathway Types "B" and "C" local leakage measurements as required by the NRC I&E

Information Notice 85-71. The resulting reported "as-left" Type "A" containment leakage at

41.86 psig is .293 percent of the contained mass per day. The acceptance criteria for this test

as contained in the facility Technical Specifications is that leakage cannot exceed 0.375 percent

of the contained air mass per day for either the "as-found" or "as-left" case.

II. TEST DISCUSSION

A. Descri tion of the ontainment

The containment vessel completely encloses the entire reactor and reactor coolant system to

ensure no leakage of radioactive materials to the environment in the unlikely event of a loss of

coolant accident.

The containment system incorporates a free-standing containment vessel surrounded by a low-

leakage concrete shield building. A four-foot annular space is provided between the outer wall

of the containment vessel and the inner wall of the shield building to allow filtration of

containment vessel leakage during accident conditions to minimize off-site doses.

The free-standing containment vessel is a two-inch thick hemispherical dome and two-inch thick

~

~

~ellipsoidal bottom. The overall vessel dimensions are 140-foot diameter by 232-foot high. The

essel wall thickness is increased to a minimum of four inches adjacent to all penetrations arid

openings. The vessel is fabricated of ASME-SA 516 Grade 70 fully killed pressure vessel

quality steel plate. The net free volume of the containment vessel is 2.5 x 10'ubic feet.

The containment vessel structure includes one personnel airlock, one emergency escape lock,

one fuel transfer tube, one equipment maintenance hatch and one seal-welded construction hatch.

All process piping and electrical penetrations are welded directly to the containment vessel

nozzles with the exception of the main steam, main feedwater, and fuel transfer tube

penetrations. These penetrations are provided with testable multiple ply expansion bellows to

allow for thermal growth or building differential motion.

The containment vessel is designed and constructed in accordance with the requirements for

Class MC vessels contained in Section IIIof the ASME Code (1971 Edition). The containment

vessel is code stamped for a design internal containment pressure of 44 psig at a temperature of

64'F. The containment vessel and all penetrations are designed to limit leakage to less than

0.5 percent by weight of the contained air per day at the above design conditions. The

culated peak accident pressure for the design basis accident for the St. Lucie Plant Unit No.

is 39.6 psig.

B. Descri tion of ILRT Instrumentation

The containment system was equipped with instrumentation to permit leakage rate determination

by the "absolute method." Utilizing this method, the actual mass of dry air within the

containment is calculated. The leakage rate becomes the time rate of change of this value. The

mass of air (Q) is calculated according to the Perfect Gas Law as follows:

Q=~Pv VRT

where: P - Containment Total Absolute Pressure

Pv - Containment Water Vapor Pressure (Average)V - Containment Net Free VolumeR - Gas ConstantT - Containment Absolute Temperature (Average)

The primary measurement variables required are containment absolute pressure, containment

relative humidity, and containment temperature as a function of time. During the supplementary

verification test, containment bleed-off flow is also recorded;

The average containment absolute temperature is determined by measuring discreet local

temperature throughout the containment and applying a mass and volume weighted averaging

technique. The volume fraction for each sensor is determined based iupon solid geometrical

calculations. The average containment absolute temperature is found using:

Vf;

where: T - Containment Absolute Temperature (Average)T; - Local Temperature for Sensor iVf; - Volume Fraction for Sensor i

verage containment water vapor pressure is determined by measuring discreet relative

umidities throughout the containment, converting this to local vapor pressures using local group

temperatures, steam tables, and applying a mass and volume weighted averaging technique. The

volume fractions for the relative humidity sensors are determined in the same manner as for the

temperature sensors above. The average containment water vapor pressure is determined by:

Pvj = (%RH)j—————x (Psat for TLocalj)100

The Instrument Selection Guide, or ISG, is used to determine the ability of the instrumentation

system to measure the leakage rate. The calculated ISG for this test met the acceptance criteria

for all test instrumentation systems.

1, Tem erature Instrumentation

Forty (40) precision Resistance Temperature Detectors (RTDs) were located throughout the

containment to allow measurement of the weighted average air temperature. The location of the

temperature detectors in the containment is depicted in Figure 1. Each RTD sensor was supplied

with a calibrated resistance versus temperature curve accurate to +0.5'F. The sensitivity and

repeatability of each RTD sensor is less than +0.01'F.

The signal conditioning circuit and readout for the RTD sensors was a Fluke data logger

perating in a constant current mode. The operating parameters for the RTD constant currentI

card are accuracy of +0.16'F and resolution of +0.01'F.

ch RTD was in-situ calibration checked after installation to verify correct operation, The data

ogger operating as a total loop with an RTD in the circuit had a repeatability of J0.02'F and

a resolution of +0.01'F.

2. Humidit Instrumentation

Ten (10) Resistance Humidity Detectors (RHDs) were located throughout the containment to

allow measurement of the weighted average containment vapor pressure. The location of the

RHDs in the containment is depicted in Figure 2. The calibrated accuracy of the RHDs is +2.5

percent RH, the repeatability of the RHDs is +0.25 percent RH, and the sensitivity, of the RHDs

is +0.1 percent RH.

The readout device used for the RHDs was a Fluke data logger. The repeatability of this device

is'0.01 percent RH while the resolution of the device is +0.01 percent RH.

ch RHD was in-situ calibration checked after installation to verify correct operation.

3. Pressure Instrumenta ion

Two Volumetrics precision pressure monitors measure containment absolute pressure. Figure 3

depicts the arrangement of the tubing connections between the monitors and the containment.

Either monitor could be used as the primary pressure sensor for leakage rate calculations with

the remaining sensor as a backup. The calibrated accuracy of the monitors is +0.015 percent

of reading. The sensitivity, repeatability, and resolution of the monitors is +0.001 psi. Binary

Coded Decimal (BCD) output from both monitors connects to the Fluke data logger.

4. Flow Instrumentation

A variable area float-type rotameter was used to superimpose leakage during the supplementary

5. Instrument election Guide S alculation

The Instrument Selection Guide is a method of compiling the instrumentation sensitivity and

resolution for each process measurement variable used during the ILRT and evaluating the total

instrumentation systems'bility to detect leakage rates in the range required. The ISG formula

is described in the American National Standard ANSI/ANS 56.8-1987. Although the ISG is a

very conservative measure of sensitivity, the general industry practice as for this test has been

o require sensitivity at least four times better than the containment allowable leakage or

ISG < 0.25La.

The calculated ISG for the instrumentation used for this test was .0027 percent per day, for an

8-hour test. The allowable value for this test is 0.25La or 0.125 percent per day, for an 8-hour

test. The ISG calculation met all recommended criteria and demonstrated the ability of the ILRT

instrumentation system to measure containment leakage with a sensitivity exceeding that required

by the appropriate industry standards.

C. ntainment Pressurization ui ment

The equipment used to pressurize the containment is shown in Figure 4. The ten oil-free

industrial diesel-driven air compressors had a total nominal capacity of 13,200 ACFM. The

compressed air was then routed to water-cooled aftercoolers, moisture separators, and refrigerant

air dryers. This equipment assured that clean, and dry air was used to pressurize the~

~ontainment.

Descri tion of the Com uter Pro ram

The Ebasco ILRTcomputer program is an interactive program written specifically for fast, easy

utilization during all phases of the ILRT and CLRT. The program is written in a high level,

compiled, structured language and operated on an MS-DOS personal micro-computer. The

program has been verified and meets all requirements of the Ebasco Quality Assurance Program.

Normal data entry to the computer is automatic via the data logger, As necessary, data entry

and modifications are readily accomplished manually by the data acquisition team. Besides

providing extensive data verification routines, the program calculates total time and mass point

leakage rates and the 95 percent Upper Confidence Level for these leakage rate calculations.

Methodology and calculations in the program drive from American National Standards ANSI

N45.4-1972, American National Standard ANSI/ANS 56.8-1987, and Topical Report

BN-TOP-1, Revision 1. Containment air mass is determined from mass weighted sensor

readings as described in EPRI Report NP-2726, November 1982.

A given instrument may be deleted from the calculations ifa sensor malfunctions. The deletion

of a given instrument is performed on all samples in the data base. Volume fractions for the

remaining instruments of that type are then recalculated based upon the placement and the

amount of containment volume sensed'by these instruments.

,Data evaluations are enhanced by the flexible display of either sensor variables or various

computed values in tabular or graphical form on the computer screen or printer. Data is

recorded on magnetic media to prevent loss during the testing. All data is stored on the

computer system in use, with retrieval capability to any desired database throughout the testing.

Two computer systems are utilized, one for data acquisition and one for data analysis.'ne

computer can serve for both data acquisition and data analysis in the case of equipment

malfunction.

Data rejection based upon the Chauvenet criterion may be utilized in the analysis, ifrequired.

Ancillary portions of the computer program assist the user in determination of temperature

tabilization, determining the ILRT termination criteria, performing ISG calculations, performing

in-situ instrument loop performance calculations and determination of acceptable superimposed

CLRT leakage verifications.

Temperature, pressure, and humidity data transmit from the ILRT instrumentation system to the

computer via an RS-232 link at 20 minute intervals. Figure 5 depicts the connection between

the ILRT instrumentation system and the computer analysis system.

E. Descri tion of the Testin S uence

The ILRT instrumentation system checks found RTD-33 recording eratically. RTD-33 was

declared inoperable prior to pressurization and deleted from the ILRT. The volume fractions

for the remaining RTD channels was recalculated following the deletion of RTD-33. All other

ILRT instrumentation was declared operable with performance within manufacturer's tolerances.

ressure sensor No. 2 was selected to be the primary pressure instrument, as it had exhibited

better repeatability and stability during the in-situ testing.

Two penetrations were required to be in service during the ILRT and were not lined up to

simulate accident conditions, P-52D gLRT Pressure Sensing Line) and P-52E gLRT Controlled

Bleedoff Line). These two ILRT penetrations are used to conduct the test and cannot be

positioned in the post-accident lineup. The minimum pathway leakage for those penetrations,

determined during Type "C" local testing, is added to the measured ILRT leakage to account

for these penetrations being in service during the test (refer to Appendix A).

Preparations to pressurize the containment for the conduct of the ILRT included internal and

external inspections of the containment structure; installation and checkout of the ILRT

instrumentation; Types "B" and "C" local leakage rate tests; alignment of valves and breakers

for test conditions; and the installation and checkout of the. temporary pressurization facilities.

These preparations were completed on May 19, 1993.

ressurization of the containment structure started at 0320 hours on May 19, 1993, at an average

ressurization rate of 4.5 psi/hr. Appendix B.1 presents a figure entitled "ILRT Testing

Sequence" that depicts the sequence of testing.

During the initial stages of pressurization, fan cooler units 1B and 1D were in service and

utilized to provide a better mixing ofpressurization air with the initial containment atmosphere.

Fan cooler 1D was removed from service at 0420 hours and 1B was removed at 0430 hours after

both reached 155 amps for operation.

Pressurization was secured at 12:39 hours on May 19, 1993, at a final pressure of 56.56 psia

(41.86 psig). This pressure is 2 psi above the minimum test pressure to account for the expected

pressure decrease due to temperature stabilization and to allow for some leakage margin during

the test sequence.

Data acquisition and analysis for the temperature stabilization phase was begun at 12:42 hours

n May 19, 1993. Plots of containment air mass versus time demonstrated that leakage might

exist above the "as found" ILRT acceptance criteria at a 95% upper confidence level. At 14:30

hours, the leakage survey teams found that the containment emergency sump suction isolation

valves MV-07-2Aand 2B were leaking air into the safety injection system. As these valves are

not containment leakage paths in accordance with the FSAR and technical specifications, a

decision was made to manually tighten these valves with no penalty to the "as-found" ILRT

values. These valves were manually tightened shortly after 14:45 hours on May 19, 1993, and

the stabilization phase was extended to monitor whether this correction was acceptable. The

containment stabilization was met at 16:42 hours on May 19, 1993, after four hours of data

acquisition to assure stabilization. Stabilization was extended and with air mass, temperature,

and pressure demonstrating smooth and expected behavior, all stabilization criteria contained in

Topical Report BN-TOP-1 were declared met.

Integrated leakage rate measurements were initiated at 18:25 hours on May 19, 1993. At 20:10

hours, the control room reported a pressurizer low level indication. Charging was initiated at

20:30 hours and completed at 21:10 hours, increasing the pressurizer level 20%, or 44 gallons

er minute for 48 minutes (2112 gallons or volume of 282.3 ft'). The decrease in pressurizer

vel was caused by an approximate 1.87 gpm reactor coolant leak in the shutdown cooling

system outside of containment. This leak could not be isolated without altering the ILRT valve

lineup. This net loss of RCS inventory was equivalent to a .004 %/day containment leak. The

decision was made to complete the ILRTwith this RCS leak present. Conducting the ILRTwith

this RCS leak gives an overly conservative representation of containment leakage.

It was determined that the change of 282.3 ft in volume provided by charging the pressurizer

would adversely affect leakage observations made thus far during the test. The addition of 2112

gallons provided a decrease in containment volume and was observed by the ILRT

instrumentation as a leak into containment. Thus the 48 minutes of "in leakage" analyzed with

the predictable trends observed from 18:25 to 21:10 on May 19, 1993 provided overall leakage

rates which might be suspect to CLRT acceptability.

The determination was to restart the test following the charging of the pressurizer to obtain test

ata which would provide a predictable trend and provide for a more solid assurance of CLRT

confirmation.

The ILRT was restarted at 21:05 hours on May 19, 1993 and after eight hours of ILRT data

accumulation, all Topical Report BN-TOP-1 acceptance criteria for the ILRT were met with

stable and predictable trends. The ILRT was officially terminated at 05:05 hours on May 20,

1993.

At 05:05 hours, a super-imposed flow equivalent to .293 %/day was initiated using the

rotameter. This flow was maintained during the required BN-TOP-1 controlled leakage rate test

(CLRT) stabilization period of approximately one hour.

At 06:05 hours, on May 20, 1993, the leakage rate measurements for the CLRT were initiated.

Stable and acceptable leakage rate measurements were observed for four hours. At 10:05 hours,

all Topical Report BN-TOP-1 criteria were met for the CLRT verification test, and the test was

eclared acceptable.

10

epressurization of the containment structure was initiated at 10:07 hours on May 20, 1993, at

rate of 6 psi/hr. At .5 psig, a containment entry was made to conduct the post-ILRT

containment inspection. The only damage observed included several broken light bulbs which

were left lying at the at the polar crane elevation.

The ILRT test sequence was officially terminated at 18:00 hours on May 20, 1993, with less

than .4 of a psig in the containment.

III. ANALYSIS AND INTERPRETATION

A. In trumentation S stem Performance

Only the RTD-33 temperature detector, which was deleted prior to the pressurization of the

containment, failed to perform properly. All of the remaining temperature detectors

performed as expected with no anomalous behavior detected by the Ebasco ILRT computer

program error checking routines. This computer program also determines the in-situ

temperature loop repeatability which consists of process measurement variations as well as

sensor noise. The average in-situ loop repeatability for the 39 operating temperature sensors was

.013'F, with the worst sensor exhibiting an in-situ loop repeatability of .041'F. This

performance compares well with the vendor-claimed temperature sensor loop repeatability,

excluding process variations, of 0.02'F as given in Section II.B.1.

~

~

~

~

Ten relative humidity sensors were installed in the containment for the ILRT. The ten operating

hannels for humidity operated as expected with no anomalous behavior detected by the ILRT

computer program error checking routines. The average in-situ loop repeatability for the relative

humidity sensors was .100 percent RH, with the worse sensor exhibiting an in-situ loop

repeatability of .229 percent RH. This performance is better than the vendor claimed humidity

sensor loop repeatability, excluding process variations, of 0.25 percent RH as given in Section

II.B.2.

Two pressure sensors were installed for the ILRT, with one utilized for testing and one

considered as a spare. Prior to containment pressurization, computer analysis demonstrated that

pressure sensor 1 was more stable over an eight-hour period than the other sensor. During the

ILRT, the in-situ pressure loop repeatability for both sensors was 0.0010 psi. This performance

compares well with the vendor-claimed pressure sensor loop repeatability, excluding process

variations, of 0.0015 psi as given in Section II.B.3.

The variable area rotameter performed as expected with no evidence of unstable readings, float

ticking, or moisture in the float tube.

12

In summary, all of the ILRT test documentation performed in an adequate manner to allow

etermination of containment leakage rates to the sensitivity required.

B. Tem rature Stabilizati n Pha e

Prior to pressurization of the containment, the atmosphere was very stable with an average

temperature of 85.53'F and a maximum spread of temperature from the highest reading sensor

to lowest reading sensor of 2.4'F. During pressurization, the heat of compression of the air

occurs mainly at the top of the containment with colder pressurization air being added at the

bottom. At the end of pressurization, the average temperature was 100.72'F with a maximum

spread of temperature from the highest reading sensor to lowest reading sensor of 26.46'F.

The results of the temperature stabilization phase are presented in Appendix B.2. The

acceptance criteria given in Topical Report BN-TOP-1, Revision 1, are described in Note 2 in

that appendix. The data presented shows that a smooth and predictable temperature stabilization

~

~

ccurred. At the end of stabilization, the average temperature was 92.6TF with a maximum

spread of temperature from the highest reading sensor to the lowest reading sensor of 11.2'F.

This demonstrates that the heat sinks of concrete and steel in the containment were quickly

returning the containment atmosphere to a stable condition.

C. Leaka e Surve Phase

As the containment began to stabilize, a preliminary review of leakage rate demonstrated

excessive leakage values. Leakage survey teams reported that a leak on both containment

emergency sump suction lines had been found by venting air from the outboard side of isolation

valves MV-07-2A and 2B. Observations by the leakage survey team allowed for the possibility

that these two emergency sump suction isolation valves were not fully closed.

These two isolation valves are not considered as potential leakage barriers in the Final Safety

Analysis Report (PSAR) Sections 6.2.4.2 and 6.2.4.4, as they willbe water covered in a Loss

fCoolant Accident and open during the recirculation phase of the transient. Any water leakage

13

through these valves in the closed position will be returned to the containment by the Safety

jection System pumps. No potential containment leakage or off-site dose is credible due to

seat leakage of these valves in the closed position.

These two isolation valves were then manually closed with subsequent containment leakage rates

reduced.

No other appreciable leakage was noted by the survey teams and the ILRT phase was initiated.

D. Inte rated Leaka e Rate Phase

Leakage measurements were started after stabilization and resolution ofpressurizer level changes

at 21:05 hours on May 19, 1993. As previously mentioned in Section II Part E, the charging

of the pressurizer was observed as "in leakage" during the test and, when coupled with the

predictable leakage data, warranted restart of the ILRT test sequence, The level change

decrease) over the period of the test, however, was not viewed as a problem. The slow and

gradual decrease in pressurizer level would be observed as a leak by the ILRT instrumentation

(because a decrease in level means a proportionate increase in containment volume). Therefore,

the leakage rate observed would be conservative in that it was accounting additionally for

pressurizer level decrease. It would be expected that this predictable trend would be confirmed

with the CLRT but may be low within the CLRT acceptability range.

Stable leakage rates were measured by both the total time method and mass point method. The

total time BN-TOP-1 results for eight hours of leakage measurements are presented in Appendix

B.3. A summary of the measured leakage by both methods after eight hours is:

BN-TOP-1Total Time

ANSI 56.8~Mass Pain

Simple Leakage Rate 0.116 %/dayFitted Leakage Rate 0.154 %/dayUpper Confidence Level 0.293 %/day

0.116 %/day0.123 %/day0.133 %/day

14

~

~

The higher upper confidence level of the BN-TOP-1 measurements is due to the nature of

rforming regression analysis on simple leakage rates instead of regression analysis on masses

and the more conservative statistics utilized by BN-TOP-1. The measured leakage rates and

upper confidence levels for both calculated methods were slowly decreasing with time.

As all acceptance criteria for a Reduced Duration BN-TOP-1 ILRT were met at eight hours as

presented in Appendix B.2, the ILRT was declared acceptable. Appendix A presents the

corrections to the measured ILRT leakage rates for local leakage rate measurements for both the

"as-found" and "as-left" cases. As a result of the Type "B" and "C" local leakage rate testing

and repairs performed during the refueling outage, additions to the "as-found" Type "A" ILRT

results were necessary to NRC Information Notice 85-71. These additions were for the

reduction in minimum pathway leakage due to repairs. These leakage reductions have been

corrected for uncertainties prior to being added to the measured ILRT values (refer to

Appendix A).

Verification ontrolled Leaka e Rate Phase

'ubsequentto the acceptance of the ILRT results, a superimposed leakage equivalent to 0.293

percent per day was added to the existing containment leakage using the variable area rotameter.

A one-hour stabilization period was allowed to lapse after addition of this leakage in accordance

with the requirements of Topical Report BN-TOP-1.

Leakage measurements were initiated to verify the results of the ILRT. The minimum duration

for the Controlled Leakage Rate Phase was determined to be four hours in accordance with

Topical Report BN-TOP-1. As presented in Appendix B.4, the leakage measurements met the

acceptance criteria for the verification phase. Leakage results for both the total time and mass

point method are:

BN-TOP-1Total Time

ANSI 56.8Mass Point

Simple Leakage RateFitted Leakage Rate

0.353 %/day0.328 %/day

0.353 %/day0.348 %/day

The acceptance criteria for this test is leakage between .322 and .572 percent per day. Results

ere expected to be low within this range due to pressurizer level change and the conservatism

of the measured leak as previously discussed in Section IIIPart D. The results of the CLRT are

acceptable.

APPENDIX A

TABULATIONOF "AS-POUND" AND "AS-LEFT" ILRT RESULTS

Correction of ILRT Results for "As-Found" Case

In accordance with NRC ISAAC Information Notice 85-71, the following additions are required

to the ILRT results due to repairs and/or adjustments made due to local leakage rate testing

during the 1993 refueling outage. The corrections include only repairs or adjustments made to

containment leakage boundaries which were made prior to the ILRT. These corrections are the

difference between the pre-repair and post-repair leakages calculated in the minimum pathway

case and corrected for uncertainties in the measurements.

The total ILRT "as-found" correction can be found adding the above ILRT corrections (NOTE:

A conservative simplification was made by not performing a root-mean-square summation of the

local uncertainties).

Correction of ILRT Results for "As-Left" Case

The only correction for the "as-left" ILRT case involves the penetrations which were in use

during the test, P-52D and P-52E. From the above section, the ILRT "as-left" correction can

be determined:
