UNIT 1 ILRT FINAL REPORT INTRODUCTION This report describes the Second 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 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 March 4th through April 22nd, 1994. Local Leak Rate Testing required to determine the final values

) of containment leakage were performed between March 18th through April 20th, 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 February 2nd through March 5th, 1991.

The Type A test was performed at the beginning of the refueling outage to test the containment in an "AS FOUND" condition without any repairs or

) adjustments.

The test was performed in accordance with 10CFR50 Appendix J, and the Braidwood Station Technical Specifications. The test method 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 areas

) and both Equipment and Emergency hatches. Some leakage paths were identified and at the time considered not to be significant. Once containment test pressure was reached and temperature stable the computer results of the total containment leakage rate exceeded .75L.

The identified leakage paths were isolated one at a time and each isolation was given sufficient time for the containment to stabilize. Even with the

) identified leakage paths isolated the total containment leak rate still exceeded the . 7 5 L. . It was noticed that a significant leak was coming from under the Emergency Hatch. Personnel were dispatched to investigate the leak and quantify it if possible. Looking at prints of the Emergency Hatch construction, it was observed that there are 6 vent plugs under the hatch that were used to pour cement under the hatch during construction, and after the cement was poured these vents were to be seal welded. It was determined to take data of the containment j for Information Only to assess the total containment leakage and evaluate the data for reference. After data was taken the containment was depressurized and an internal inspection of the emergency hatch was performed. It was found that the vent plugs under the hatch did not have the required caps seal welded on them.

It was determined to weld caps on the vent plugs and perform a local leak rate on each vent to quantify the leakage. Other liner checks were made to verify that there wasn't any other areas that could have caused the leak to migrate to the

) Emergency Hatch, none were found.

With all the identified leak paths returned to original line-up Containment Pressurization was re-started. During pressurization personnel were sent to all the penetration areas and the Equipment and Emergency Hatches to check for leaks.

The area under the Emergency Hatch did not show signs of leakage during the second test pressurization after the vent caps had been installed. Some of the same leakage paths were isolated again once test pressure was reached and ,

l temperature was stable, time was given between each isolation for containment to I stabilize. The leak rate still exceeded .75L., Initially it was thought that the observed leakage through the Service Air (SA) penetration was insignificant.

Leakage through the SA penetration was significantly reduced by pressurizing between the SA containment isolation valves to slightly below containment test pressure. Once this task was accomplished the containment leak rate dropped to a value below . 7 5 L. .

o:\corresp\zestech\ilrtrpt.wpf 1 t-

J UNIT 1 ILRT FINAL REPORT The test was then successfully continued until completion. The isolated s 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 0.04499 wt%/ day at a test pressure greater than 44.4 psig ( P. ) . The associated 95% Upper Confidence Limit (UCL) was

_. 0.04574 wt%/ day.

J The verification induced leak rate test result was measured at 0.1284 wt%/ day. This compares with the sum of the measured leak rate phase result (0.04499 wtt/ day)and the induced leak of 7.7 scfm (0.09979 wt%/ day),

The composite leak rate of 0.1284 wt%/ day lies within the allowable tolerance band of 0.14478 wt%/ day 0.025 wt%/ day.

) After the ILRT, during the refuel outage, LLRTs were performed. The results from some of these tests 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 27.411 scfh or 0.00592 wt%/ day. Adding this leakage to the ILRT 95% UCL yields a total of 0.0517 wt%/ day which is less than the 0.075 wt%/ day acceptance criteria.

UNIT 1 ILRT FINAL REPORT 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 2. 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 changed.

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 5 minutes. This included data set number, time, temperature, relative humidity in degree F and absolute pressure readings. The data was sent

) to a personal computer via proper computer cables. The computer stored the data every time the data was collected and every 30 minutes the data was manually stored to disc. Personnel monitored the data either in graph or numerical form.

Each data set was real time, this facilitated the identification of trends as they developed.

A.3 PRE-TEST CONTAINMENT STRUCTURAL EXAMINATION

)

i 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 j during A1R02. No degradation of the containment structure was noticed since the i

previous inspection was performed.

) A.4 TYPE A TEST INSTRUMENTATION j a. Temperature Thirty-one type Graftel smart sensor model 9202 thermistors were used through out the containment. All sensors were calibrated using standards t

traceable to the National Bureau of Standards (NBS).

UNIT 1 ILRT FINAL RFPORT A.6 ILRT PLANT SYSTEM LINEUP

) The valve and equipment lineups were detailed and specified by component with individual signoffs. The lineups ensured containment integrity conditions 1 as close as possible to those which would exist after a design basis Loss of Coolant Accident (LOCA). Penetrations were challenged by draining and venting the piping associated with containment isolation valves.

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 of the containment building on the northeast side. 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 TECHNIQUE The absolute method of leak rate determination was used. As defined in ANSI N45.4-1972 the absolute method uses the ideal gas laws to calculate the

) measured leak rate. 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 performed 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 determined 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 the Statistical Test plus the induced leak rate) provides a basis for resolving any uncertainty associated with the calculated leak rate of the Statistical leak rate test. The acceptance criterion for the induced leak rate shall be within 1 0.25L. of the

) sum of the statistical leak rate and the flowmeter induced leak rate.

B.3 INSTRUMENT ERROR ANALYSIS An instrument error analysis was performed prior to the test and at the end of the measured leak rate and induced leak rate phases of the test. The analysis was performed in accordance with the definition of the Instrument Selection Guide

) (ISG) referenced in ANSI /ANS-56.8, 1987.

The ISG is used only to demonstrate the system's ability to measure the required parameters to calculate the containment leak :e. The ISG is not based on a statistical analysis of the leak rate calculatiorm, and does not affect these calculations. The computed ISG is not added to the value of the calculated leak rate.

[) The following narrative describes the sequence of events associated with l the ILRT. In order to give a more accurate presentation of the ILRT events, both pressurizations of containment are discussed.

C.1 PRETEST PREPARATION DATE 3/4/94 1600 Initiated the start of 1BwvS 6.1.2.a-1. Activities include, verifying the prerequisites for start of test and insitue testing of all sensors to verify instrumentation is operating correctly. Other pretest miscellaneous activities which include compressor setup for the pressurization of containment, setting staging areas for

, equipment to be stored.

DATE 3/5/94 0800 Started hanging out-of-services for system lineups associated with data sheets listed in Appendix B of test procedure IBwVS 6.1.2.a-1.

DATE 3/7/94

[) 1015 Satisfactorily completed 1BwVS 6.1.3-1, " Visual inspection of the containment surfaces prior to the Type A Leak Test" No apparent changes have occurred in the visual appearance of the interior or exterior surfaces of the containment structure since the last performance of the test in February 1991 for AIR 02.

C.2 CONTAINMENT PRESSURIZATION D

DATE 3/10/94 0520 Valve lineups are complete except for RF penetration (reactor floor drains) couldn't stop the draining of system even with numerous valves other than what valves are listed in the system lineup isolated in order to drain system. The decision was made to isolate

[] that penetration and to take a penalty for the isolated system and add it to the ILRT. All pre-pressurization checks complete.

Commenced pressurization of containment.

0610 Stopped all compressors to repair drain fitting on one of the air d'yers 0740 Restarted all compressors.

]

1055 Inspection of containment penetrations for leakage found the following at Approximately 27.8 psia:

1) Emergency hatch outer door seal is leaking slightly  ;

2) Service Air penetration P-56 leaking slightly l

) 1150 Operations was attempting to enhance the isolation on service air boundary valve 1SA155 to stop leaktge from 1SA039 hoping that the )

I leakage was coming from the system instead of containment.

1220 All compressors had to be shut down due to fuel consumption rate was higher than expected and compressors were starting to run out of fuel because fuel truck hasn't arrived to support test on time.

I Containment pressure approximately 36.4 psia.

Y UNIT 1 ILRT FINAL REPORT 1255 All compressors back on line. Pressurization rate increasing same as

) before.

1845 Turned all compressors off, containment pressure 61.02 psia ambient pressure 14.51 psia. Vented between IVQO11 and OVQ002.

C.3 TEMPERATURE STABILIZATION 1925 Started temperature stabilization Data Set 141 2130 Found good size leak on VQ valves:

1VQ005B and IVQ005C 2340 Decided to stroke the leaking VQ valves since AS FOUND data for LLRT was already taken. The sequence would be to open then close IVQ005C then open and close IVQ005B that way the line would be vented for the

) test. Leak seems to have stopped will check later.

0035 Leaks identified in curve wall area: Vent for 1PS9354B, balloon fills up immediately af ter being squeezed, vent for service air penetration balloon fills half way in about 5 seconds and vent for 1RY8028 has a slight leak. Decided to close vent valve for 1PS9354B.

) 0200 1VQ005B/C appears to be leaking again.

0310 Leakage has been observed to be coming from under the emergency hatch barrel. Crawled in to look at the emergency hatch. Found a leak between the hatch barrel and the concrete. The leak was about 6 to 10 inches long. The leak was at about the 6 o' clock position. Snoop was sprayed into the crack were the leak was coming from and large

) bubbles formed. Pictures were taken to evaluate the action to be taken. Also snooped the emergency hatch inner door along the bottom and small bubbles appeared.

0840 Contacted construction supervisor to remove air line from compressors to pressurization header and install blind flange.

) 0930 Blind flange installed on containment pressurization line.

1020 Checked for leaks in the penetration areas of curve wall, leaks found coming out of vent valves: ISI005, 1CV063 and ICS014A. All leaks were small.

1035 Operators were sent out to verify the following isolation valves for tight closure: 1SI8959, 1 SIB 963, 1CV8369, 1CV8399, 1CS004A and

) ICS035A, 1155 Operators report back that valves are closed and some movement was made to the SI valves.

1450 Check VQ valves again decided to close the sparger vent valve to verify that the IVQ003 wasn't leaking.

)

1540 After leaving-the sparger valve closed for a few minutes, checked to see if there was any pressure buildup. Saw some pressure decided to leave sparger isolated, made note in APPENDIX N.

UNIT 1 ILRT FINAL REPORT 1730 Decided to confine the leak under the hatch with DOW CORNING RTV and

. POLYCELL INSULATING FOAM to a small cross sectional area so the I

leakage could be measured. The emergency hatch outer door was opened and the leak rate through the penetration did not change.

The leak under the emergency hatch was measured with a hot wire anemometer to determine an approximate leak rate, but due to the large cross sectional area the measurement wasn't accurate.

C.4 STATISTICAL LEAK RATE TEST

)

1800 A IODINE sampler was set-up to measure the amount of IODINE levels coming through the penetration boundary. Chemistry will have sample analyzed by 2000. Decided to start the statistical test for INFORMATION ONLY to get a relative leak rate to compare with the tests that will conducted while repairs commence.

t 0345 Chemistry reported that there is IODINE in the area under the emergency hatch. With this information it was evident that the air was coming from containment.

C.5 INDUCED LEAK RATE TEST DATE 3/12/94 r

0000 Started INDUCE leak rate for INFORMATION ONLY to verify that the instruments being used are operating correctly.

C.6 DEPRESSURIZATION AND POST ACTIVITIES 0435 Began to depressurize containment.

The following systems were released from the test line-ups to aid in any repairs: Service air, Instrument air and Containment ventilation mini-flow.

DATE 3/13/94 1800 Exited the ILRT procedure with all the system line-ups in the proper position for the ILRT test to continue after immediate repairs. In brief on the events that caused the ILRT to stop. The test was stopped due to a large leak under the emergency hatch. In the investigation of the cause of the leak, it was found that under the barrel plate of the hatch there are 6 bore hole pipes which were used to pour concrete under the hatch and after the concrete was poured the pipe ends were to be welded closed. They were found not to be welded and with the settling of the unit deterioration started to occur.

Tests are being conducted on all weld chase channels on the liner of the containment to check for other causes of leaks. Vacuum boxes '

were brought in to check marked areas of the liner for leaks and the pipes under the hatch are in the process of being welded closed.

1405 Closed inner emergency hatch door and opened outer door due to outer door was leaking excessively. Checked shaft seals, no leaks.

1500 Requested that Service air penetration P-56 be isolated by closing vent valve ISA039, due to high leakage.

)

1520 Suggest that a gauge be installed on vent valve 1SA039 to determine the pressure in the penetration. This allowed us to determine if the leak was from containment or the Main Service air header. Pressure was found to be 46 psig. This verified the penetration was leaking from containment. Suggested that the Main Service air header to Unit 1 Auxiliary Building be Isolated.

1720 Service air to Unit 1 Aux. Building was isolated and vented.

2015 Service air penetration P-56 was pressurized to 44 psig. Monitored regularly with Heise gauge QA# 033912br calibrated 3/7/94.

2100 Closed and capped the following valves: 1PS131 isolating IPS9354A/B, i 1PS133 isolating 1PS9355A/B, 1PS135 isolating 1PS9356A/B, 1PS137 isolating 1PS9357A/B and 1FC032 isolating 1FC009 and 1FC010. All known leaking penetrations are isolated.

DATE 3/16/94 0000 Reopened the following valves to determine the impact on the isolating service air: 1PS131, IPS133, 1PS135, 1PS137 and 1FC032, 1PS133 and 1PS137 were identified as leakers. The reason for reopening these valves was that there wasn't ample time to determine if service air was indeed the source of the major leak.

0205 Determined that leak rate was still excessive and isolated 1PS133

, 0240 Leak rate still excessive isolated IPS137 0300 Checked emergency and equipment hatch seals for leaks found none.

0400 Checked VQ valves for leaks found none. The cap was installed on the mini flow exhaust valves.

C.4' STATISTICAL LEAK RATE TEST '

0640 Started statistical leak rate test with data set 338 timed at 0637 0800 Decided to log the pressure in the pressurized service air penetration to verify that pressure was below test pressure in containment. Refer to page 14 for log readings. To help find leaks that could possibly be in the liner a tracer gas will be injected into containment and samples will be taken with large garbage bags to determine the concentration in the area.

UNIT 1 ILRT FINAL REPORT 1350 Injected SF6 into containment via vent / test valve IVQOO9 to look for leaks that can't be found. Samples will be taken at 5, 15, and 30

{) minutes af ter the injection The injection of SF6 will last approximately 5 seconds. Samples will be taken from the following areas: Electrical penetration general areas, Curve wall general area 401 and 364 elevations, A,B,C and D MSIV rooms, Emergency hatch and Equipment hatch general 426 elevation area, containment chiller rooms, and the tendon tunnels. A sampler was set up at the 401

-) elevation of the Arxiliary Building. A special test procedure, SPP# 94-011, was initiated for this evolution.

1430 Found traces of SF6 in B and C MSIV rooms, Zone 4 electrical penetration, equipment hatch had a high concentration of SF6 leakage.

Snooped the equipment hatch for leaks didn't find anything at any of the seals, but when snooped the liner where the barrel meets the m concrete at the 3 o' clock position found large leak. Will snoop area

> at NOP/NOT to see if the leak is only at high pressure.

1515 Snooping the Zone 4 electrical penetration to locate the leak found with the tracer gas. Couldn't find leak. Determined that the tracer gas at the penetration area was caused by a draft in the door leading to the equipment hatch where a large leak was detected.

) 1530 In the special procedure for the injection of a tracer gas it has you run the RCFC's in low speed for proper mixture before or during de-pressurization. After some investigation, decided not to start the RCFC's for mixture at a pressure greater than 20 psig. The fans would trip on overcurrent at this pressure. The reason has to do with density. Currently containment is at 46 psig of air. Tne design

_ for the RCFC's is for 46 psig of steam. The density of air is almost

1) twice as much of steam. Therefore the mass flow through the fan will double causing the fan motor to draw more current than design, causing the fan motor to trip.

1700 Continued to monitor the MASS PLOT LEAK 24 hr TEST. NO other incidents occurring, scheduled to finish test at 0630 on 3/17/94.

v F. TEST RESULTS AND INTERPRETATIONS The results given in this section are for the actual test performed and not the aborted test. The values in the aborted test were for INFORMATION ONLY and used as an aid for trouble shooting and a reference value.

G F.1 STATISTICAL LEAK RATE TEST RESULTS The "AS FOUND" statistical average leak rate (95% UCL) before any corrections was 0.04574 wt%/ day. The "AS LEFT" statistical average leak rate (95% UCL) after corrections was 0.0517 wt%/ day.

m 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 did not significantly changed from the beginning to end of the test.

There were no instrument failures or any eratic indications.

O During pressurization a number of leakage paths were identified. The magnitude of leakage from these paths could not be 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 pressure was stable. After the containment reached test pressure the total containment leak rate exceeded .075L.. Looking for penetrations that were

[) potential leakers we came across some slight leaks and one major leak, the following were found: P-56, P-70 and the emergency hatch outer / inner door were swapped. Penetration P-70 has 4 lines that go through that penetrati.on two of the four were isolated, due to the leakage being excessive. Penetration P-56 was determined to be the major leak. A number of activities were performed to verify the leak was actually coming from containment and not, the service air system.

The penetrations were isolated one at a time and the effects on the total containment leakage rate was observed. With the isolation of penetration P-70 and the swapping of the emergency hatch doors the leakage rate was still above the .075L.. It was only after the isolation of penetration P-56 did the leakage rate fall below the .075L.. Penetraticn P-56

, was isolated by pressurizing between the containment isolation valves to a J

pressure slightly below test pressure (43.8 psig)

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 of these pathways. i gg It is ComEds policy to Type A test containments in as close to the Post LOCA condition as possible. The pathways were left isolated in this case for l i

the following reasons: '

1 For all cases, there were no direction dependency concerns. The leakage measured by the Type C tests performed after the Type A test can in all cases clearly be shown to yield results conservative relative to what gp would have been their actual contributions had they remained open during the Type A test.

The cumulative effect of suddenly opening all the pathways may have had the effect of destabilizing the centainment atmosphere. This would have both extended the test duration and reduced the quality of the results.

O gg (7/14/94) 32

UNIT 1 ILRT FINAL REPORT d l 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.

APPENDIX G TYPE B AND C LOCAL LEAK RATE DATA Local leak rate testing has been performed once (A1R03) since the last ILRT performed in 1991 (A1R02), and were performed after the ILRT performed in

() March of 1994 (A1R04). Results indicated for A1R03 and A1R04 are "AS LEFT" LLRT values performed during the outages. Several Containment penetrations, including the containment airlocks and purge valves, are tested at more frequent intervals, as specified by the stations Technical Specifications.

The results below represent the periodic Type B and C LLRTs performed at 18

month intervals as specified in 10CFR50 Appendix J. l l
