INTRODUCTION The Prestart Test Program Integrated Leakage Rate Test (ILRT) was conducted on the reactor containment building at the Comanche Peak Steam Electric Station Unit I during the period July 4-7, 1989.
The test was conducted to demonstrate that the' leakage from the reactor containment system at the design loss of coolant accident pressure does not exceed the maximum allowed by the plant Technical Specifications (Reference 6.1).
The ILRT was conducted in accordance with the plant test procedure EGT-701A Revision 1 (Reference 6.2).
The test procedure conformed to the general testing requirements established in 10CFR50 Appendix J (Reference 6.3), ANSI N45.4 - 1972 (Reference 6.4), ANSI /ANS 56.8-1981 (Reference 6.5), and ANSI /ANS 56.8-1987 (Reference 6.6),

TEST SYNOPSIS Preparation for the Integrated Leakage Rate Test (ILRT) included installation of a temporary pressurization system that included oil free air compressors and refrigerated dryers, instrumenting the containment with temperature, dew point and pressure monitoring sensors, and process system valve lineups.
I Prior to pressurization of the containment for ILRT, prerequisites specified in the test procedure (Reference 6.2) were completed.
Specifically, a survey of the containment exterior and accessible interior was performed per 10CFR50 l
Appendix J (Reference 6.3).
No evidence of structural deterioration was found during the containment inspection. Also, a containment temperature survey was conducted to determine that the ILRT instrumentation will accurately represent containment atmospheric conditions during the test. The containment temperature survey was conducted with containment fans off, a condition that was also maintained during ILRT.
Records of satisfactory completion of the i
test prerequisites is documented and records are maintained in the Official Test Copy of procedure ECT-701A, Revision 1.
Containment pressurization was started at 2033 hours0.0235 days <br />0.565 hours <br />0.00336 weeks <br />7.735565e-4 months <br /> on July 3, and a pressurization rate of approximately 3.6 psi /hr was maintained.
Pressurization system consisted of air compressors with an aggregate capacity of 14,400 scfm, after cooler, and a refrigerated air dryer.
During containment pressurization the containment fan coolers, with cooling water through the cooling coils, were run to control air temperature and prevent stratification.
Pressurization was stopped at 0400 on July 4 to investigate decreasing level indication in the Reactor Coolant Drain Tank.
The reading was determined within expectations and l
pressurization was resumed at 0619 on July 4.
Pressurization was stopped at i
1443 and a blind flange was installed in the pressurization line at 1550 on July 4.
Containment pressure was at the test condition of 49.3 psig.
Containment fans were stopped, cooling water to the cooling coils was isolated, and a temperature stabilization period was started.
Temperature stabilization criteria specified in Reference 6.2 were met four hours after reaching the test pressure. However, the measured leakage at the end of stabilization period was excessive. A survey of all containment penetrations was initiated to determine cause of high leakage rate.
Instrument air isolation valves 1-HV-3487 and 1-01-030 were inadvertently cycled during leak search. Therefore a LLRT penalty is taken for this penetration.
Leak search results indicate that there was no significant leakage through the containment isolation valves before or after being cycled.
Leakage from a containment recirculation sump was found and isolated at the containment spray pumps 1 and 3.
No penalty is taken for this penetration as this system retains water filled. A blind flange was installed to isolate containment purge at valve 1-HV-5538.
A penalty is taken for this penetration. Following restoration of the ILRT valve lineup, the ILRT was started at 1415 hours0.0164 days <br />0.393 hours <br />0.00234 weeks <br />5.384075e-4 months <br /> on July 6.
At the end of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the ILRT start, the leakage rate and 95 percent Vpper Confidence Levels as specified in the Reference 6.2, for Mass Point Analysis were satisfied.
Total Time Analysis, although not required per the procedure, is also reported for information. During the entire ILRT test period the containment pressure remained between 48.3 and 50.0 psig as required. 1
i following the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of ILRT, a supplemental verification test was conducted.
At 1420 hours0.0164 days <br />0.394 hours <br />0.00235 weeks <br />5.4031e-4 months <br /> on July 7, a steady leakage of air at a rate equal to 8.96 scfm from the containment was established. After one hour of stabilization the leakage rate was measured for a period of four hours to verify accuracy of i
the ILRT instrumentation and the test methodology. The supplemental verification test validated the test results and ILRT instrumentation. After completion of verification test the containment was depressurized to O psig.
Various items of data needed to support or supplement the ILRT were recorded at regular intervals during the test, as required by the test procedure. All recorded data are included in the Official Test Copy of the procedure (Reference 6.2).
Data required to support ILRT results are included here in App ndix C.

TEST METHODOLOGY The integrated leakage rate test is performed to verify that the leakage from the containment system at calculated accident pressure does not exceed the specified limit.
The containment is prepared for tie test by closing all access ways and aligning valves in post accident position.
All valves are closed using normal means and without exercising or using excessive force.
The valves not aligr.ed in the >ost accident condition are listed in Section 5 of 6
this report. Measured lea (age through these valves, using minimum pathway analysis, is added to the UCL to account for the non. standard lineup. All items that could be damaged by test pressure are removed from the containment l
or vented.
Pressure sources inside the containment are vented or removed, i
Leakage Rate Measurements j
The test objective is accomplished by pressurizing the containment with clean and relatively dry air. The containment atmospheric parameters are measured using the ILRT instruments described in Section 3.
Containment average drybulb temperature, wetbulb temperature and absolute pressure are i
measured. Using the ideal gas law, containment air mass is calculated at every 15 minute interval.
The loss of containment air mass over a specified seriod determines the leakage from the containment. After a leakage rate has seen 4
determined, the calculational method is verified by a supplemental test during which an additional known leakage is imposed on the containment and a new leakage rate is calculated, j
Leakage Rate Calculational Methods Containment leakage rate is calculated using the mass point method described in Reference 6.6.
The method uses containment pressure, drybulb temperatures l
and dewpoint temperatures recorded every 15 minutes as input data.
The mean absolute temperature of the containment was calculated using method described in Reference 6.5.
The measured dewpoint temperatures are used to calculate the l
water vapor pressure in the containment atmosphere.
Evaporation and condensation of water changes the partial pressure of the vapor phase. This partial pressure is subtracted from the containment absolute pressure so that the internal phase changes are not erroneously accounted for as actual in or out leakage from the containment. The mass of dry air in the containment is calculated using the ideal gas law, with average containment temperature and dry air pressure.
The calculated air mass is plotted against time.
The slope of the l
regression line (best fit line) through the air masses is defined as the mass point leakage rate.
The measured leakage rate at a given time is defined as the calculated change in the air mass since the start of the test divided by the elapsed time since the start of the test.
The mass point method utilizes the variance of data points about the regression line to establish a 95 percent Upper Confidence Limit on the leakage rate.
Reference 6.6 describe the calculation method in detail.
After pressurizing the containment to test pressure the containment atmosphere is required to stabilize for a minimum of four hours. Once the stabilization criteria specified in the test procedure are satisfied the test may be started.
The lea (age rate is calculated for a test period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
i 10-
l i
l Following determination of the leakage rate the test results are verified by the supplemental verification test.
The supplemental test consists of imposing 3 known amount of leakage from containment (normally La) and measuring the increased leakage rate. The new calculated leakage rate must equal previously calculated leakage rate plus the imposed flow within the allowable tolerance of 25% of La. The supplemental test has a duration of at least four hours.
l Test data collected during the test and leakage rate analysis are presented j
in the Appendix C.

ANALYSI' AND INTERPRETATION S
5.
The sumary of test results presented in Section 3 of this report is based on data collected during the test. These results must be corrected for the penetrations in non-standard alignment and adjustments must be made for any water level changes during the test.
Local Leakage Rate Addition A number of mechanical systems that penetrate containment and systems that are assumed to be drained and vented post LOCA were maintained in operation or were not vented during the test. To account for leakage which would have passed through these penetrations in the normal post LOCA configuration, the minimum pathway local leakage is totaled and the total is added to the calculated leakage rate UCL. Table 5.1 lists all such penetrations and the penalties associated with them.
Water Volume Correction During the Type A test, water levels in the reactor cavity sump, containment sumps 1 and 2, containment CCW drain tank, accumulators 1-4, and aressurizer relief tank were recorded hourly during the test. Level changes osserved during the conduct of the test are listed in table 5 2.
The water volume changes is equivalent to a leakage rate of 0.0008 %/ day.
Composite Test Results The composite leakage rate is the sum of the calculated rate, the correction for the water level changes and local leakage rate penalties.
The final results are sumarized as follows:

The Bechtal IIRP ocmputar pww.wi is used to detemine the integrated leakage rate of a ruclear primary contaiment structure. 7he program is used to ocagute leakage rata based on igut values of time, free air volume, contaiment atnosphezu total pressure, drybulb tasperature (mean 'Naperature, calculated usirg ANSI /ANS 56.8-1981),
ard dowpoint temperature (water vapor pressuru).
Imakage rata is ocmputed usirg the Absolute Method as defined in ANSI /ANS 56.8-1987, "contaiment System Imakage Testing Requirements" and Bi-cop-1, Rev 1, "'Mstirg Critaria for Integrated Imakage Rata 'Nsting of Primary contaiment Structures for Nuclear Power Plants". 7he program is
}
designed to allow the user to evaluate containment leakage rate test results at the jobsite during contalment leakage tasting. Current leakage rate values may be obtained at any time during the tastiry period using one of two ocmputational methods, yieldirg three diffarent report printouts.
[

In the first printout, the 7btal Time Report, leakage rata is ocmputed frm initial values of free air volume, containment atnesphere drybulb tanparature and partial pressurv of dry air, the latest values of the same parameters, ard elapsed time. These individually ocetuted leakage ratas are statistically averaged using linear regression by the method of least squares. The 7btal Time r
Method is the ocmputational technique upon which the short duration test criteria of af-cop-1, Rev 1, " Testing Criteria for Integrated Isakage Rata 'Msting of Primary containment Structures for Nuclear Power Plants," are based.

The second printout is the Mass Point Report and is based on the Mass Point Analysis 'Mchnique hibed in ANSI /ANS 56.8-1987, l
"Contaiment Systan Isakage 'hsting Requirements". The mass of dry air in the containment is ocmputed at each data point (time), using i
the Ideal Gas Law, frun current values of mean containment at iW,ere drybulb tamperature (based on ANSI /ANS 56.8-1981) and partial pressure of dry air. Contained mass is "plottad" versus time and a repassion line is fit to the data using the method of least squares. Imakage rata is detamined frun the statistically derived i
slope and intercept of the regression line.

3.0 PERMRMAllCE SUlttARY Performance of testing per ECT 701A commenced July 3, 1989 at 2033 hours0.0235 days <br />0.565 hours <br />0.00336 weeks <br />7.735565e-4 months <br /> by starting pressurisation of containment using 14, 400 SC m of compressor capacity. The pressurisation rate was maintained less than 5.0 psi / hour in accordance with ECT 701A. At 0400 hrs (7/4) pressurization was halted due to a concern on Reactor Coolant Drain Tank (RCDT) level anomalias and tank venting.
TDR 8251 was written and after evaluation it was determined the RCDT level was behaving within expectations.' At 0619 hours0.00716 days <br />0.172 hours <br />0.00102 weeks <br />2.355295e-4 months <br /> pressuriza-tion was resumed. At 1443 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.490615e-4 months <br /> pressurization was completed after obtain-ing test pressure.
At 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br /> (7/4) the Temperature Stabilization sequence was entered. At 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br /> preliminary calculations revealed that leakage was greater than allowable and leakage survey teams were sent out to find possible sources.
Some leakage was found by the teams and the source locations recorded in the test log.
In the process of trouble shooting leak sources, instrument i
air valves 1 HV 3487 and 101-030 (penetration MIII 22) and 48" HVAC contain-sent isolation valve =1 HV 5538 (MV 02) were stroked (see TDR 8252 and 8256).
Since the valves were stroked, these penetrations are included as pensity leakage additions.
Containment Spray Pumps 01 and 03 suction, discharge and eductor isolation manual valves were closed due to leakage through pump seals and casing gaskets (see TDR 7999).
Containment Spray Pumps 02 and 04 suction valves were closed but later reopened prior to the ILRT sequence start. Blind flanges were installed on H2 Purge and Exhaust Valves'1 HV-5540 (MIII-19) and 1 HV 5542 (MIII 18) but later removed prior to ILJtT start. N2 blankets were instituted on 48" Containment Purge and Exhaust penetrations MV 01 and MV 02 but were rencved prior to IIJtT start. At 2220 hours0.0257 days <br />0.617 hours <br />0.00367 weeks <br />8.4471e-4 months <br /> (7/5) a blind flange was installed on 1 HV 5538 (MV-02) and left in l
place throughout the 11JtT.
At 0230 hours0.00266 days <br />0.0639 hours <br />3.80291e-4 weeks <br />8.7515e-5 months <br /> on 7/6 the Temperature Stabilization sequence was declared complete, the IIAT sequence begun, and NRC personnel informed. At 1000 hrs. (7/6) mainsteam vent valves 1MS 382,-385,-388, and.392 were found closed.
Per ECT 701A these valves are allowed to be closed and opened to do leak checking of the steam generators. TDR 8254 was written and after evaluation it was decided to open the valves and restart the IIJtT sequence for conservatise sake.
At 1415 hrs. (7/6) the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> IIJtT was restarted and NRC notified of the new start time. At 1415 hrs. (7/7) the IIJtT sequence was completed with a final 954 Upper Confidence Limit (UCL) of.0234/ day determined without penalty leakage inclusion.

At 1430 hrs. (7/7), after creating a superimposed leakage of approximately 8.9 SC M, a one hour stabilisation sequence was begun prior to entering the Verification test.
At 1530 hrs. (7/7) the Verification Test was started.
At 1930 hrs. the Verification Test was completed with a final Composite Leakege Le determined to be 115t/ day and average superimposed leakage of 105t/ day (8.96 SCFM).
Following the Verification Test, preparations were made to start depressurising and leakage troubleshooting was performed on i
Containment Spray System Train A (Pumps 01 & 03). At 2200 hrs (7/7) depres-l surisation was begun. Containment was entered with.2 psig pressure remain-ing to prepare for personnel entry and begin restoration activities.
At approximately 2200 hrs. (7/8) depressurisation ended with containment at O psig.
Clearances on systems / components were released, IIJtT instruments removed, containment inspections performed, and other restoration activities continued.
During the restoration process penalty leakages were determined for s
Instrument Air penetration MIII-22 and Containment Purge Exhaust penetra-tion MV-02.
"As Found" L1JtTs were performed, the CIVs stroked, and then "As IAf t" LIJtTs done. Since the "As Found" leakages were within their allowable L1JtT range, no corrective actions were implemented prior to the "As laft".
The penalties ("As IAft" Einimum pathway) with measurement in-accuracy included were 632 SCCN for MIII-22 and 1842 for MV 02, resulting in a total of 2474 SCCN. Combined with the planned penalty leakages of 60.99 SCCN, the total of all penalties if 2534.99 SCCM which translates to.00114/ day.
Also evaluated for impact on the overall leakage rate was water level changes in tank and sumps communicating with Containment atmosphere.
Those that indicated change during the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> I1JtT were as follows:

Containment Sump #2 806' to 806'3" 6
Reactor Coolant Drain Tank 34.9% to 35.9%
0.5 L
i Pressuriser Relief Tank 724 to 734 18.5 Total 25.0 For conservatism sake, since these levels increased during the I!JtT, they are factored into the overall leakage determination. The total of a 25.0 cubic foot level increase over 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is equivalent to a leakage of
.00084/ day. Therefore, the 954 UCL + "As Left" penalty leakages + water level change correction came to.023t/ day +.00114/ day +.0008t/ day for a total of
.0249t/ day (ie
.0254/ day).

1 Pes) 5 of 7 I
l Concerning isolation of Containment Spray System (CT) pumps 01 and 03, following completion of the verification test with containment still at l.
test pressure, pumps 01 and 03 discharge isolation valves were opened. No increase in the pumps pressure was observed. However piping between recir-culation sump valve 1 HV 4782 (penetration MS 3) and pump suction valves was found to be air fi Sed.
When the pump suction valves were opened the i
pump pressure increaset Following completion of depressurization, an "As l
l' Found" 1.1JtT was performed on 1-HV 4782 with the leakage found to be within F
allowable I.IAT range. Then the valve was stroked and an "As left" 1.LJtT i
done.
The "As Found" value was 3040. SCCN and "As 14ft" 953 SCCN.
Since l
the valve was within allowable range no corrective actions were needed. A 4
leakage test of CT Pumps 01 & 03 was performed by pressurizing the pumps to 49 psig.
Pump 01's leakage was determined to be approximately 32,000 SCCM and Pump 03's between 20,000 and 32,000 SCCN.
Evaluating the CT Pump 01 & 03 situation, it was determined recire sump l_
valve 1 HV 4782 was leaking through at 3040 SCCN, allowing air to fill piping displacing water / air through CT Pump 01 & 03 seals and casing gaskets, till the suction piping was predominantly air filled. Concerning l
application of a penalty leakage for the CT Systesi, it was determined to be nonapplicable since the-CT recirc sump (inside Containment) and piping is water filled during and post accident (see FSAR Table 6.2.4-2, item
- 127 & Note #9).
Therefore leakage through a possibly inoperable CT Train A would be only of water, not Containment atmosphere.
If Train A was oper.
L ating the water would be recirculating back to Containment.
1 It was found even with penalty leakage inclusion and considering the leak-age isolated through CT Pumps 01 & 03, that the total would not have caused failure of the IIAT.
Further evaluation recommends, for future tests, that manipulations not be performed too early inside the stabilization sequence.
Although the temperature stabilization criteria was met within the first six hours, a large temperature difference between the bottom and top of I
containment remained.
It is felt the test would have passed with no mani-pulations being performed, if a longer stabilization time (i.e. 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />),
had been utilized.
Five other TDR's beside those mentioned above and a total of 15 TPC's were l^
generated during the course of the test and its preparation and restoration l
activities. None invalidated the test results nor impacted the test objec-
[
tives.
See page 6 of 7 for individual itemization and status of TPC's and TDR's.
The TPC's will os evaluated for inclusion permanently in ECT 701A and incor-porated either by procedure revision or procedure change notice.

1 l-There were 26 TPCs written during the performance of ECT 716A, all of which were non. intent chonse in nature. TPCs 019, 020, 021, 022, 023 and 024 were written to allow testing by the water addition method.
TPCs 001, 002, 00), 004, 008, and 025 changed the valve lineups on their i
associated tests to facilitate better isolation, easier lineup, or delete valves outside required test boundary.
TPCs 005, 010, 011, 014, and 015 are in response to DCAs adding valves or changing valve number assignments.
TPCs 009, 012, 013, 017, and 018 change direction of i
testing to forward from reverse to better satisfy the intent of 10CFR50 Appendix J. TPC 016 adds penetrations requiring flanges to procedure. TPC
. 007 facilitates more efficient testing of electrical penetration assemblies.
TPC 006 addresses completion of system piping separating units 1 and 2.
TPC 026 was a temporary change to allow testing from l
SFCDs building while Containment Area was inaccessible due to painting.
ECT 716A should be revised to incorporate all of the TPCs written with i
the exception of TPC 026.
The following TDRs were generated during performance of ECT 716A. All were satisfactorily rotested after rework by the responsible organisation, or revision of test method, as applicable.

Test of 1 8840 was completed satisfactory. On 04/22/89 Retest #1 was performed for 1 88098 af ter drainage boundary valves were adjusted and results were
. satisfactory.
On 07/02/89 Retest #2 was performed to test 1 88098 and 1 8840 due to a test sage found to be out of calibration.
TDRs 7327, 7337, and 7380, 7744 and 7745 were generated during test performance and are closed.
A recommended permanent change to the procedure would be to allow for higher test pressures due to piping being pressurized.

ECT 795A Sqgl681 1.0 0&JECTIVES:
o ECT.795A " Type 'C' 14 cal 1Aak Rate Test for Penetrations MII.02 and MII.03' was performed to quantify leak rates on RNR Hot legs 1 and 4 containment isolation valves 1 4701A and 1 87015 as well as 1 8708A and 1 87085.
The leak rates are to be added to the totals from ECT 716A to satisfy the requirewets of 10Cm50 Appendix J and Technical Specification 3.6.1.25.
2.0 STATENENT OF CRITERIA AND RESULTS ACHIEV,Eg Each of the four valves tested was reufred to meet an acceptable leakage rate when pressurized to between 48.3 ESIC and 50.0 PSIC.
leakage criteria for 1 8701A and 1 87018 is 3500 SCCN each.The acceptable 1 4704A and 1 87088 For valves The test results are as follows:the acceptable leakage criteria is 350 SCCN each l-Valve Test Pressure Leakane

.1 87088 49.5 PSIG 158 SCCN Note:
1 87015 required ratesting after initial failuse of test.
TDR 7915 was generated to document the test failure and required Start up to perform an EE.10.
The retest results are those noted above.
Because the valve passed the 14ak Rate Test following the EE.10, the determination is that the valve was not seating full depth prior to the EE.10, 3.0 PERFORMANCE SUMMA 11Y I
ECT 795A was started on June 22, 1989 on ni he shift with the testing of
[
S valve 1 87018.
The test failed due to leakage past the seat.
TDR 7915 was written and Start up performed an EE.10 after which the leak rate retest passed.
1 87088 was the second valve tested. This is a pressure relief valve that is tested from the discharge side.
l-A work package to break the inlet and discharge flanges to rotate the valve in place was required due to the number of restraints on the discharge side of the piping.
The leak rate test was satisfactory and work package SWP Z.4992 replaced the valve to complete the work.
3 14op was returned to OPS and A loop testing started on June 24, 1989 with the satisfactory testing of 1 8701A. Valve 18708A was tested on June 25, 1989
,resulta using traveler SWP.Z.4991 to provide support for rotation andwith satisfactory reinstallation of the valve.
During the testing of 1 8708A it was noted that there was no " Quality Related" stamp on the cover sheet to EGT 795A.
l DR P89 1679 was written to document the deficiency.

l At the completion of testing, the RHR system was returned to OPS control.
