UNIT 2 ILRT FINAL REPORT

INTRODUCTICN This report describes the Second Type A Containment Leakage Rate Test conducted af ter the initiation of comercial service for the Braidwood Nuclear
)
Power Station Unit 2 containment building. This report is prepared pursuant to the requirements of 10CFR50 Appendix J, Section V.B.3. The test was l conducted through the perfomance of Braidwood Procedure 2BWVS 6.1.2.a-1, l " Unit 2 Prima Containment Type A Integrated Leakage Rate Test", dated October 27th h November 9th, 1994. local Leak Rate Testing required to determine the fina values of containment leakage were performed between September 10th through November 15th, 1994. Also included in this report is a
) summary report of all the periodic Type B and C Local Leakage Rate Tests that were performed since the last Type A ILRT performed on September 12th through November 16th, 1991.
The Type A test was performed at the end of the refueling outage. All local leak rate test were performed in the beginning of the outage, with the exception of the ones isolated during the ILRT. Those penetrations were
) re-tested to determine the final leak rate of containment.
The test was perfomed in accordance with 10CFR50 Appemdix J, and the Braidwood Station Technical Specifications. The test method that was used was the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Mass Plot Method During pressurization leak checks were conducted in all penetration 3 areas and both Equipment and Emergency hatches. Some leakage paths were
/ identified and at the time considered not to be significant. Once containment cest pressure was reached and temperature stable the computer results of the total containment leakage rate exceeded the 0.75L . a The identified leakage paths were isolated one at a time and each isolation was given sufficient time for containment to stabilize. With the identified leakage paths isolated the total containment leak rate was below
) 0.75L,.
Approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> into the test it was observed that data had not been collected for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 45 minutes and it was determined to stop the test. Found instrumentation problem and restarted test after repairs.
The test was then successfully continued until completion. The isolated
) pathways were left isolated during the entire test. A Minimum Pathway As Found penalty was later assessed for each penetration isolated.
Using the Mass Plot Method the total primary containment leak rate was calculated to be less than the allowable leak rate of 0.075wt%/ day (0.75L ) .
The leakage rate was calculated to be 0.04853 wt%/ day at a test pressure greater than 45.4 psig (P ) . The associated 95% Upper Confidence Limit (UCL) was 0.04944 wt%/ day.
l The verification induced leak rate test result was measured at 0.1285 wt%/ day. This compares with the sum of the measured leak rate phase result (0.04853 wt %/ day)and the induced leak of 7.8 scfm (0.1010 wt%/ day) .
The ecmposite leak rate of 0.1285 wt%/ day lies within the allowable tolerance band of 0.14953 wt%/ day 2. 0.025 wt%/ day.

UNIT 2 ILRT FINAL PEPORT n
LJ Before and after the ILRT, LLRTs were ptrformed. The results from some of these test are added to the final ILRT total as the corrective leak rate.
These are added for the systems that were not properly challenged during the ILRT. The AS FOUND minpath leakage for all corrections was 17.3 scfh or 0.00373 wt%/ day. Adding this leakage to the ILRT 95% UCL yields a total of 0.05317 wt%/ day which is less than the 0.075 wt%/ day acceptance criteria.

A. TEST PREPARATIONS A.1 TYPE A TEST PROCEDURE
.g The ILRT was performed in accordance with Braidwood Procedure 2BWVS 6.1.2.a '., Revision 1. Temporary Procedure Changes were made to the procedure to correct for typos, add or delete steps to ensure the proper execution of the test. The original intent of the surveillance was never change.
A.2 TYPE A TEST PROGRAM AND DATA PROCESSING g The program used for this test is the Duke Power Integrated Leak Rate program Rev 1.75, software ID# GN09405. Containment parameters were acquired by the program every 10 minutes. This included data set number, time, temperature, relative humidity in degree F and absolute pressure readings.
The data was sent to a personal lap top computer via proper computer cables.
The computer stored the data everytime the data was collected and every 30 minutes the data was manually stored to disc. Personnel monitored the data either in araph form or numerical. Each data set was real time, this O facilitateil the identifications of trends as they developed.
A.3 PRE-TEST COtEAINMETE STRUCIURAL EXAMINATION Prior to the containment pressurization, a visual examination of all accessible interior and exterior surfaces was performed. The results of this inspection were compared to the findings of the structural inspection
$ performed during A2R02. No degradation of the containment structure, was noticed since the previous inspection was performed.

UNIT 2 IIRT FINAL REPORT A.6 ILRT PI1MI' SYSTEM LINEUP The valve and equipment lineups were detailed and specified by component with individual signoffs. This ensured containment integrity conditions as close as possible to those which would exist after a design basis loss of
) Coolant Accident (LOCA) . This also assured that penetrations were properly drained and vented. Since the, ILRT was perfonned at the end of the outage 3 penetrations were not properly challenged. This was due to the amount of water and time it would take to p.operly align the penetrations.
A penalty was assessed for these penetrations.
A.7 TYPE A TEST PRESSURIZATION
) To pressurize containment to full test pressure, a system of 11 diesel driven, oil free compressors were used. The compressors were located outside on the northeast side of the containment building. Pressurization was accomplished through a six inch header which penetrates containment at penetration P-4. Once the containment was pressurized, the pressurization header was isolated and vented.
)
B. TEST METHOD B.1 STATISTICAL ANALYSIS TEO NIQUE
) The absolute method of leak rate detennination was used. The absolute method uses the ideal gas laws to calculate the measured leak rate, as defined in ANSI N45.4-1972. The inputs to the measured leak rate calculation include subvolume weighted containment temperature, subvolume weighted vapor pressure, and total absolute air pressure.
B.2 SUPPLEMENTAL VERIFICATION TEST (Induced Leak Rate)
)
The supplemental verification test is perfonned by intentionally inducing a controlled leak of a magnitude approximately equal to L. (0.1 wt%/ day). This induced leak is superimposed on the previously detennined leak rate (Statistical Test) and compared with the leak rate calculated during the Statistical leak rate phase. The combined leak rate (calculated leak rate from Statistical Test plus the induced leak rate) provides a basis for
) resolving any uncertainty associated with the calculated leak rate of the statistical leck rate test. The acceptance criterion for the induced leak rate shall be within 10.251,4 of the sum of the statistical leak rate and the flowmeter induced leak rate.

F. TEST RESULTS AND INTERPRETATIONS F.1 STATISTICAL LEAK RATE TEST RESULTS
)
l The "AS FOUND" statistical average leak rate (95% UCL) before any corrections was 0.04944 wt%/ day. The "AS LEFT" statistical average leak rate (95% UCL) after corrections was 0.05317 wt%/ day.
l Containment dry air temperature and relative humidity trended downward throughout the test. This is indicative of a stable containment with no major heat sources as the reactor coolant was kept reasonably constant throughout the test. Measured tank and containment sump levels were not significantly changed from the beginning to end of test.
l There was two instrument failures. One was temperature sensor which was blocked and replaced with one near by (T26 was replaced with T27). The other failure was signal converter box (black Box) had a erroneous malfunction which resulted in restarting the statistical test.
)
l Durir ressurization a number of leakage The l magnitudeok$eakagefromthesepathscouldnotbthswereidentified. quantified by visual observation, although they appeared to be small. It was decided to continue !
with the pressurization and measure the total containment leakage rate once l containment pressure was reached and stable. After the containment reached f
test pressure the total containment leak rate exceeded 0.75L,. Looking for penetrations that were potential leakers we came across some slight leaks, the following were found: P-1, P-11, P-28, P-70 and the equipment hatch inner / outer door were swapped. Penetration P-70 has 4 lines that go through that penetration 1 of the 4 was isolated due to the leakage being excessive.
Penetration P-28 was the major source of leakage.
The penetrations were isolated one at a time and the effects on the
) total containment leakage rate was observed. With the isciation of the penetration P-70, P-11, P-1 and the swapping of the equipment hatch doors the leakage rate was still above the .75I S. It was only after the isolation of penetration P-28 did the leakage rate fall below .75L .
The test was then successfully continued until completion. The isolated pathways were left isolated during the entire test. A Minimum Pathway As Left penalty was later assessed for each of these pathways and for the pathways
) that were not lined up for the ILRT (P-21, P-24 and P-25) . Other penalties were added to the ILRT for the penetrations that were repaired during the refuel outage.
{ It is CtmEds policy to Type A test containments in as close to the Post f
LOCA condition as possible. The pathways were left isolated in this case for the fr2 lowing reasons:
D For all cases, there were no direction dependency concerns. The leakage measured by the T, C tests performed after the Type A test can in all cases clearly be s.own to yield results conservative relative to what would have been the;r actual contribur.icns had they remained open during the Type A test.
) h cumulative effect of suddenly opening all the pathways may have had the effect of destabilizing the containment atmosphere. This would have both e.: tended the test duration and reduced the quality of the results.

It is always desirable to minimize the number of valve manipulations during ILRTs. This reduces the potential for line up errors and other unforeseen problems.
