' INTRODUCTION - Containmrnt Integrated Leakage Rate Test, 1982 ,

This report contains a discussion of the Beaver Valley Power Station, Unit No. 1, containment leakage testing since the last performance of the Type A Leak Test in November 1978. It has been prepared in accordance with the requirements of 10 CFR 50, Appendix J, Section V, paragraph B.3. Part I discusses this May, 1982 performance of the Containment Type A Integrated Leak Rate Test. Part II summarizes the results of the containment local leak testing performed since the last Type A Test.

SUMMARY

OF' EVENTS After the completion of all prerequisites (i.e. - system alignments, equipment calibrations, computer program checkout, etc.) the pressurization of the reactor containment building was started at 2112 hours0.0244 days 0.587 hours 0.00349 weeks 8.03616e-4 months on May 9, 1982.

It can be noted here that two changes were made to Type "A" equipment subsequent to the Novmeber, 1978 Type "A" test te improve upon the perform-ance of this test.

First, the interface between the quartz manometer (for measuring containment pressure) and the process computer was changed from an analog voltage signal to a binary coded decimal (BCD) signal improving on the accuracy of the computer readings for the Type "A" test. Voltage fluctuations in the analog signal coming into the computer were causing the computer readings of the manometer to fluctuate excessively; thus the manometer readings had to be manually entered into the computer by a test engineer periodically during the previous Type "A" test. But with the addition of the BCD inter-face, the manometer readings had a high degree of accuracy and repeatability thus sparing two test engineers from the monotonous task of manually inputting the readings into the computer.

The second modification was an upgrade of the Type "A" computer program. This modification consisted of 1) changing the calculations from hourly to every ten minutes and 2) using a real time clock for the calculations. This increase in the number of data sets resulted in a better least squares fit for the leakage rate calculation and also a more realistic confidence- level .

The pressurization of the containment continued smoothly until a pressure af approximately 47 psia was reached inside tne containment. During a routine survey for leaks, pressure was discovered increasing inside the

personnel airlock.

Initially the decision was made to let the airlock pressurize along with the containment and use the airlock's outer door as the pressure boundary. Unfortunately, the outer door had a minor seal leak to the outside atmosphere which at this time was suspected to be greater than the acceptable leak rate.

The leakage rate measured on the computer was approximately 20 pound mass of air per hour (Lbm/hr) which was greater than the 15 Lbm/hr acceptable leakage rate. An investigation into a design change which had just been completed on the airlock showed that an emergency access equalizing (whistle) valve had been installed on each airlock door and was probably the reason for the pressure increase inside tue airlock.

This modification consisted of a two inch diameter steel shaf t (locking pin) through the door which operated the equalizing valve depending on the shafts' position, in or out.

The differential pressure exerted a force on the end of the shaft forcing it to slide inward, opening the equalizing valve and creating a flow path f rom the containment into the airlock. To defeat this setup, entrance was made into the airlock and the steel shaft was secured such that the equaliaing valve was in the closed position. During the remainder of the test, the pressure in the airlock stayed at 0 psig.

In continuing with the test, a leakage rate of approximately 20 Lbm/hr was still being measured.

An intensive investigation into all systems for leakages and valve alignments was implemented. At first the only leaks found were very minor, i. e. - flange gasket leaks or valve packing leaks. Then it was discovered that the river water system to the inside containment recir-culation spray heat exchangers was drained when it should have been filled (as in normal operation) for the test. Further investigation revealed that three of the four penetrations were under vacuum while the fourth had a positive pressure of 7 psig. It was suspected that a vent or drain valve on the heat exchanger may have been inadvertently lef t open or a hole was Paea_3

OF EVENTS (CONTLNOED) .

i present in the metal expansion joint inside containment. Either condition would provide a direct air path from the inside to outside containment showing up as a leak on the calculations. The river water system to each heat exchanger was isolated by shutting the inlet and outlet isolation motor operated valves.

The Type "A" computer program was re-initialized at 1620 hours0.0188 days 0.45 hours 0.00268 weeks 6.1641e-4 months on May 12, 1982. After several hours of data acquisitions, a leakcge rate of approximately 7 Lbm/hr (0.04%/ Day) was measured which was well within the acceptable limit of 15Lbm/ Day (.075%/ Day). The test continued for a full 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months without any additional adverse encounters. At 1620 hours0.0188 days 0.45 hours 0.00268 weeks 6.1641e-4 months on May 13, 1982 the Type "A" test was concluded with a leakage rate of 0.0239%/ Day and a 95% confidence level of 0.0019%/ Day. '

The Mass Step Change Verification Test was then performed. For this verification test 240 pounds mass of air per hour was pumped into the containment via the station air system over a two hour period. This mass of air was measured by both a calibrated mass air flow meter and the Type "A" instrumentation system (process computer). The mass air flow meter measurement of 440.5 pounds mass verses the Type "A" instrument system measurement of 412 pounds mass were in agreement by 4.03% (adjusted for measured type A leakage rate during the two hour test) which is well within the allowable 25.0%.

The completion of the verification test concluded the Type "A" ILRT.

Depressurization was started on May 14, 1982 at 0045 hours5.208333e-4 days 0.0125 hours 7.440476e-5 weeks 1.71225e-5 months and the contain-ment reached atmospheric pressure at 2200 hours0.0255 days 0.611 hours 0.00364 weeks 8.371e-4 months . Afterwards general equipment and system restoration was completed.

'PART I - Containm:nt Integrated Leakage Rate Test, 1982 E. ERROR ANALYSIS INSTRUMENTATION SELECTION GUIDE (ISG)

The Instrumentation Selection Guide (ISG) formula is used to determine the ability of an instrumentation system to measure the integrated leakage rate of the primary reactor containment system. The ISG formula is not based on a statistical analysis of leakage rate calculations, but has been developed for instrumentation selection. The ISG computed is not added to the value of the calculated leakage rate, but is used for instrument selection and loss of sensor criteria only.

PART I - Containment Integrated Leakage Rate Test, 1982 F. TYPE C AS - FOUND VS. AS - LEFT ANALYSIS The requirements of 10CFR50 Appendix J, Section III.A.l.2 specify that the Type A test to be performed on the reactor containment building in as close to the "AS FOUND" condition as practical; i.e. - no repairs or adj ustments (RA's) to the primary containment boundary so that the containment can be tested in the "AS - FOUND" condition. Because this isn't always practical during an outage where the Type B and C local leakage rate tests are usually performed and necessary repairs made prior to the Type A test, an analysis was made of the leakage rates of the repaired penetrations both before and after repairs to determine any local leakage rate correction to be added to the Type A test results. These corrections would result from any RA's performed prior to the Type A test and would be used to assess the containment integrity following a period of operation.

The following table is a summary of the AS - FOUND verses AS - LEFT leakage rates from the 1982 Type C testing program. Note that Type A add on leakage only occured if the total penetration leakage decreased as a result of repairs to both the inside and outside isolation valves. If repairs were performed on only one valve and the other isolation valve measured an acceptable leakage rate, the assumption was made that no leakage change resulted from the repairs; that is the containment integrity was maintained by the acceptable valve. As can be seen from the table, only two penetrations (40 and 64) qualified as having repairs made to both isolation valves thereby reducing the leakage rate prior to the Type A test. Thus the total add on leakage rate is 475.97 SCF/D or 0.00734 J;/ Day. (See Section G, conclusions of this report) .

The total Type A leakage is within the BVPS technical specification limit

, of 0.075 %/ Day leakage, and also the verification test was satisfactorily j completed which confirms the capability of the Type A test method and equipment to determine the containment leakage rate. The effects of the two major problems and their significance on the Type A test results are examined below.

1) The air inleakage from the reactor containment into the airlock as a l result of the newly installed equalizing valve on the airlock's inner door had no effect on the outcome of the Type A test. When the locking pin (shaf t) was j secured such that the equalizing valve remained in the closed position, no I

leakage occured into the airlock. This is the normal position of the valve and it is the position the valve would be in during a DBA. After the completion l of the Type A test, an engineering evaluation was performed and a modification

1 .

j made to the equalizing valve to assure containment integrity during a DBA or ;

LOCA.

f

Note: The air path from the equalizing valve into the airlock was plugged

and a Type C test performed to verify no leakage.

l PART I - Containment Integrated Leakage Rate Test, 1982 G. CONCLUSION (CONTINUED)

2) The cause of the initial high leakage rate was determined during the test to be a leak path through one of the recirculation spray heat exchanger's river water piping. The 1B heat exchanger was the most suspect because the pressure in the river water line was approximately 7 psig while the other three were negative pressure (indicating vacuum). For the Type A test, the river water lines were supposed to be filled with water as they would be during a DBA, but because a hydrostatic test was performed on this system just prior to the Type A test, the lines were inadvertently left drained. The river water outside containment isolation valves were then all shut, thereafter the leakage rate dropped to an acceptable level. After the Type A test, an investigation was performed to determine the actual leak path, which was originally suspected to be an open vent or drain valve on the heat exchanger. All the vent and drain valves were found to be closed, but while performing a pressure test on i

the 1B river water system, a hole was discovered in the metal expansion joint inside containment. This would be a direct flow path from inside to outside containment with the outside isolation valves open and the system drained. It could not be determined what caused the hole, but the expansion joints had been removed and reinstalled during the outage prior to the Type A test. The defective joint was then replaced with a new one.

This situation does not contain any unreviewed safety questions, as this condition has already been addressed in the Beaver Valley Power Station Unit #1 FSAR, section 6.4.4.

Also, it can be verified this leak was not. present during cycle 2 operation as it would have been discovered by an abnc mal amount of containment vacuum pump operation.

The result of having a hole in the expansion joint during a DBA would depend on the containment pressure. If this pressure was less than the river water pressure in the system, a small leak would occur out of the expansion joint, resulting in a very small dilution of the sump. If the containment pressure would exceed the river water pressure, as it might for a relatively short time during a DdA, (less than one hour) a radioactive leak may occur through the river water system. This leak would be detected by the 13 RSHX river water radiation monitor and could be isolated by the operator. thus, terminating the release. The important fact is that the river water system would be filled Page 21

and operational during a DBA and ths.refore, isolating the river water lines during the test was a justified response to the initial high leakage rate. !

If the system had been filled at the start of the type A test, as it should have been, the leakage rate would have been acceptable from the beginning.

4 PART II - Local Leakage Rate Test .

INTRODUCTION Local leakage rate testing of the reactor containment building penetrations is performed regularly (approximately every refuelin,g outage) to determine the leakage rates of the isolation valves and other isolation barriers, i e. electrical penetrations, airlocks, etc.

The combined leakage f rom all penetrations and valves subject to Type B and C tests shall be less than sixty percent of the maximum containment allowable leakage rate (.60 La) tested at a minimum test pressure, Pa. The maximum allowable leakage rate (La) is 0.10 percent per day of the containment internal air mass or 6489.80 SCF/D. The maximum leakage for the local leakage rate test is therefore 3893.88 SCF/D.

PART II - Local Leakage Rate Tests A. TYPE B TEST RESULTS Local leakage rate testing for the containment electrical penetrations (Type B testing) has been performed twice since the last November,1978 Type A test; once in May, 1980 and again in March, 1982. The results were acceptable for both series of tests.

The local leakage rate testing for the containment electrical penetrations measures the leakage through the penetration 0-ring seals on the bolt-on flanges and the leakage from the penetration canister. A summary sheet is included listing the electrical penetration leakage rates for each series of tests.

Other Type B leakage rate tests measure the leakage through the personnel airlock, the equipment hatch, and the fuel transfer tube. The results of these tests are also included on the summary for reference.

PART II - Local Leakage Rate Test B. TYPE C TEST RF LTS The purpose of T"pe C testing is to demonstrate the integrity of the containme ' isolation valves in accordance with Appendix J of Title 10 Code of Federal Regulations Part 50 and BVPS Technical Specification-3.6.1.2.

Two complete series of Type C tests have been performed since the November, 1978 Type A test. The first series of Type C tests was performed during the period of March through September, 1980. The second series of tests was performed from January through May,1982. Both series of Type C tests were completed satisfactorily meeting the applicable acceptance criteria and both are summarized on Tables #1 and 2 respectively.

It should be noted that for the 1982 series of tests, five new penetrations had been added during the previous outage, all of which were Type C tested.

The initial leak test was performed 4/28/80. Valve [MOV-CC-112B3]

would not hold the applied pressure. Maintenance Work Request MWR-800468 was initiated and the motor operator limit switch set-point adjusted. The retest was performed 5/19/80, with a leakage of .1524 SCF/D.

Penetration #7 (OST 1.47.9)

The initial leak test was performed 7/28/80. Valve (SI-83] was leaking 375.4 SCF/D. Maintenance Work Request MWR-801945 was initiated and the disc surfaces were lapped, new lock wire and new flexitallic gaskets were installed.

The retest was performed 8/4/80 with a leakage of 245 SCF/D.

Penetration #9 (OST 1.47.11)

The initial leak test was performed 3/9/80. Valve [TV-CC-111Dl] was leaking 94.996 SCF/D and valve [TV-CC-111D2] was leaking 87.09 SCF/D.

Penetration #48 (OST 1.47.39)

The initial leak test was performed 4/16/80. Both valves on the penetration had acceptable leak rates. However, the outside isolation valve

[TV-DG-109Al] was physically relocated, after the test was done, as per Design Change Package DCP-#103. This required a retest of the valve which was performed 8/28/80 with a leakage of 40.8 SCF/D.

Penetration #49 (OST 1.47.40)

The initial leak test was performed 4/10/80. Valve [RC-68] would not hold the applied pressure. Maintenance Work Request MWR-800453 was initiated. A new disc, spring, and gasket were installed and the retest performed 6/16/80 with a leak rate of 18.8 SCF/D.

Penetration #56-3 (OST 1.47.47)

The initial leak test was performed 4/18/80. Valve [TV-1SS-105Al]

leaked at a rate greater than the range of the flow meters. However, no air could be detected leaking out the downstream vent, indicating that the trip valve was not leaking. To see if any of the clearance points, valves

[TV-SS-106A], [TV-SS-106B], [TV-SS-106C] and (TV-SS-106D], were leaking the valves upstream of these clearance points, [RC-1], [RC-6], [RC-8] and [RC-10]

were closed to see if the leakage would go down. First, one of these valves i

was closed, the leakage was checked, the valve was opened, then the next valve was closed, the leak rate checked, then the valve opened, etc. At no time, however, was the leak rate within the range of the flow meter. Valve

[TV-lSS-105Al} was then pressurized through the LMC outboard of [TV-lSS-105Al]

PART II - Local Lsakage Rate Test B. TYPE C TEST RESULTS (CONTINUED) for a free flow path. The leakage with this method was approximately 65 SCF/D.

This was considered a troubleshooting effort because the outboard. side of l [TV-1SS-105A] was pressurized, rather than the inboard side as required; there-fore, the test was invalid. Another attempt was made to test [TV-1SS-105Al]

with the approved method. Again, an attempt was made to 'back up' the clearance points by shutting [RC-1], [RC-6], [RC-8] and [RC-10]. During this test, however, all four of these valves were shut at the same time, unlike the first test when no two of these valves were shut at the same time. This test performed 9/30/80 resul'ted in a leak rate of 65.28 SCF/D.

Penetration #60 and #62 (OST 1.47.52)

The initial leak test was performed 6/4/80 and 6/5/80. Valve [MOV-SI-890B]

leaked excessively. The two parallel isolation check valves, [SI-13] and [SI-14],

also leaked excessively.

It was determined that [SI-13] leaked more than [SI-14].

Therefore, Maintenance Work Request MWR-800768 and MWR-800769 were initiated on [MOV-SI-890B] and (SI-13], respectively. Valve [SI-13] was cleaned and the s

flexitallic gasket was replaced. Ten rings of packing from [MOV-SI-890B] were replaced with new ones. A retest was performed 8/27/80 with a leak rate of 228.7 SCF/D for [MOV-SI-8908). Valves [SI-13] and [SI-14] again leaked excessively.

Due to the repairs made on [SI-13], it was now [SI-14] that leaked the most.

Maintenance Work Request MWR-801223 was initiated to repair valve [SI-14]. It was found that the two disc knobs were not oriented at the bottom of the installed disk (see attached figure) as required, instead, they were oriented at the top of the installed disk. In this orientation, the top of the disk was forced against the ceae. As a result, the bottom of the disk broke contact with the seat.

1 The disk was then rotated and a retest performed 9/21/80 with a leak rate of 228.48 SCF/D for [SI-13] and [SI-14].

Maintenance Work Request MWR-800%760 was initiated to repair valve (SI-23). The leak rate test was performed 8/27/80.

Valve [SI-10] leaked at 57.18 SCF/D, valve (SI-11] leaked at 8.16 SCF/D, and [MOV-SI-890C] leaked at 40.8 SCF/D all of which were acceptable.

Valve [SI-12] still could not be tested due to leakage through (SI-23].

In [SI-23] it was found that the two disk knobs were not oriented at the bottom of the installed disk (see figure) as required, instead they were orienced at the top of the installed disk. In this orientation, the top of the disk was forced against the seat. As a result, the bottom of the disk broke contact with the seat. The disk was rotated and a retest was perfor=ed 9/12/80 with a leak rate of 40.8 SCF/D for (SI-12].
