INTRODUCTION This report describes the Third Type A Containment Leakage Rate Test conducted after the initiation of commercial service for the Braidwood Nuclear
[) Power Station Unit 1 Containment Building. This report is prepared pursuant I
-to the requirements of 10CFR50 Appendix J, Section V.B.3. The test was conducted through the performance of Braidwood Procedure 1BwVS 6.1.2.a-1,
" Unit 1 Primary Containment Type A Integrated Leakage Rate Test", dated November 1st through November 16th, 1995. Local Leak Rate Testing required to determine the final values of containment leakage were performed between
) September lith through November 18th, 1995. Also included in this report is a summary of all the periodic Type B and C Local Leakage Rate Tests that were performed since the last Type A ILRT performed on March 4th through April 22nd, 1994.
The Type A test was performed at the end of the refueling outage and was considered as an "AS FOUND PASS" Type A. Test. All local leak rate tests were
']) performed in the beginning of the outage, with the exception of the penetrations isolated during the ILRT. Those penetrations were re-tested to deterndne the final leak rate of containment. The "AS LEFT" determination for this Type A Test was also considered as a "AS LEFT PASS" Type A Test.
1 The test was performed in accordance with 10CFR50 Appendix J and l Braidwood Station Technical Specifications. The test method that was used was 3 the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Mass Plot Method.
Pressurization leak checks were conducted for all penetration areas and both Equipment and Emergency hatches. Some leakage was identified from the Emergency Hatch Outer Equalization Valve and at the time considered not to be significant. Once containment test pressure was reached and temperature stablized, the computer results of the total containment leakage rate exceeded
$) the 0.75L..
The identified leakage from the Emergency Hatch Outer Equalization Valve was determined to be excessive and as a corrective action, the Emergency hatch door position were swapped. The Inner Emergency Hatch door was OPEN and was j taken to CLOSED. The Outer Emergency Hatch door was CLOSED, and was taken to {
- ) OPEN. With the identified leakage path isolated, the total containment leak !
rate measured below 0."5L.. Penetration 41 was inadvertenly isolated, when 1 the blocking device for ICV 8149B came off allowing the penetration to become isolated. 1CV8149B is in Containment and has to be blocked OPEN in order for i vent valve 1CV214B to be lined up to vent in containment. Although this penetration was not identified as a leaking penetration, a penalty was taken due to it not being lined up properly.
O 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 3 calculated to be less than the allowable leak rate of 0.075wt%/ day (0.75L.) .
The leakage rate was calculated to be 0.06174 wt%/ day at a test pressure greater than 44.4 psig ( P.) . The associated 95% Upper Confidence Limit (UCL) was 0.06324 wt%/ day.
[) 1
BRAIDWOOD UNIT 1 ILRT FINAL REPORT The verification induced leak rate test was measured at :
0.1456 wt%/ day. This value should compare with the sum of the measured leak rate phase of 0.06174 wt%/ day and the induced leak rate of 0.09715 wt%/ day, the sum being 0.15889 wt%/ day. The value measured (0.1456 wt%/ day) is within the + 0.025 wt%/ day (.25 La) tolerance band.
I
- 1.
Before and after the ILRT, LLRTs were performed. The results from some of these test are added to the final ILRT total as the corrective leak rate. 4 These corrections are added for the systems that were not properly challenged during the ILRT. The "AS FOUND" minpath leakage for all corrections was 4.4 scfh or 0.00095 wt%/ day. Adding this leakage to the ILRT 95% UCL yields a total of 0.06419 wt%/ day which is less than the 0.075 wt%/ day acceptance l criteria. i l
i A. TEST PREPARATIONS A.1 TYPE A TEST PROCEDURE The ILRT was performed in accordance with Braidwood Procedure 1BwVS 6.1.2.a-1, Revision 3.
l- A.2 TYPE A TEST PROGRAM AND DATA PROCESSING 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 lap top computer via computer cables. The computer I
stored the data and every 30 ndnutes the data was manually stored to disc.
Personnel monitored the data either in graph or numerical form. Each data set ,
was recorded in real time,'this facilitated the identifications of trends as 1 they developed.
A.3 PRE-TEST CONTAINMENT STRUCTURAL EXAMINATION 1
Prior to containment pressurization, a visual examination of accessible interior and exterior surfaces was performed. The results of this inspection were-compared to the findings of the structural inspection performed during A1R04. No degradation of the containment structure was noticed since the previous inspection.

A.6 ILRT PLANT SYSTEM LINEUP The valve and equipment lineups were detailed and specified by component
, with individual signoffs and was performed using Braidwood Station Procedure l
1BwoS 6.1.2.a-l. 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 performed at the end of the outage, 5 penetrations were not properly challenged. This was due to the amount of water l
and time it would take to properly align the penetrations. A penalty was assessed for these penetrations. Also the penetration mentioned previously (P-41) was also assessed for penalty since the blocking device failed to
) maintain the valve 1CV8149B open.
i l A.7 TYPE A TEST PRESSURIZATION To pressurize containment to full test pressure, a system of 12 diesel driven, oil free compressors were used. The compressors were located outside
, on the northeast side of the containment building. Pressurization was i accomplished through a six inch header which penetrates containment at i penetration P-4. Once the containment was pressurized, the pressurization header was isolated and vented.
B. TEST METHOD l B.1 STATISTICAL ANALYSIS TECHNIQUE The absolute method of leak rate determination 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 i subvolume weighted containment temperature, subvolume weighted vapor pressure, and total absolute air pressure.
l B.2 SUPPLEMENTAL VERIFICATION TEST (Induced Leak Rate)
)
The supplemental verification test is performed by intentionally I
inducing a controlled leak of a magnitude approximately equal to L. (0.1 l wt%/ day). This induced leak is superimposed on the previously determined leak i 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 l statistical leak rate test. The acceptance criterion for the induced leak l rate test shall be, that the Induced average composite Leak Rate is within
+ 0.25L. of the sum of the statistical leak rate and the flowmeter induced leak rate.

l F. TEST RESULTS AND INTERPRETATIONS
() F.1 STATISTICAL LEAK RATE TEST RESULTS The'"AS FOUND" statistical average leak rate (95% UCL) before any corrections was 0.06324 wt%/ day. The "AS LEFT" statistical average leak rate (95% UCL) after corrections was 3.06419 wt%/ day, 1
Containment dry air temperature and relative humidity trended downward
- throughout the test. This is indicative of a stable containment with no major s heat sources as the reactor coolant was kept reasonably constant throughout the test. Measured tank and containment sump levels were not significantly i
changed from the beginning to end of test.
This test was performed with out any penetration being isolated during
() the test, except for the inadvertent one (P-41). 4 penetrations were left isolated before the test started and were left isolated for the duration of the test. Penalties were assested for these penetrations and added to the 95%
UCL. ,
F.2 INDUCED LEAK RATE TEST
[)~ The Induced Test was performed following the Statistical Test. After a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> _ period for stabilization of the known induced leak (7.5 SCFM) the induced ,
test was started. The Induced test was completed in approximately 4.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> :
with successful results. The sum of the statistical measured leak rate ( L..)
and the flowmeter induced leak rate (Lo) was verified to be stable and within-10.25L. of the Measured Composite leak rate (Le) . No abnormal containment response or significant events occurred during this test. The results are b) listed below:
l Lo. = Flowmeter Induced leak 7.5 scfm (0.09715 wt%/ day) l L.m = Measured statistical leak rate (0.06174 wt%/ day)
Le = The measured composite Leak rate (0.1456 wt%/ day)
L. = .1 wt%/ day or 7.72 scfm O
Lo is between 75% and 125% of L..
7.5 scfm was the superimposed leak rate on the flowmeter. Le is within the acceptance criteria range of Lo + L.,i .25L.

1 F.3 COMPARISON TO PREVIOUS TEST RESULTS This was the third ILRT performed at Braidwood Unit 1. The previous test was performed March 4th to April 22nd, 1994 which was the 4th refuel outage
[) for Braidwood Unit 1.
The statistical average containment leakage rate during the 1994 test was 0.04499 wt%/ day after a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Mass Plot test. The 95% upper confidence limit of the containment leakage rate was 0.04574 wt%/ day.
The induced leak rate during the 1994 test was .1284 wt%/ day after 4 b) hours. This was within the 0.25 La of the sum of the statistical average leak rate and the induced leak rate.
