SUMMARY

The periodic Integrated Leak Rate Test (ILRT) of Prairie Island Unit 1 Containment was completed June 24,1994. This leakage rate test was performed in accordance with Prairie Island Technical Specification 4.4.A,10CFR50 Appendix J, and ANSl N45.4-1972. In addition, ANSI 56.8-1981 Mass Point calculation technique was used to analyze the data.

The test was performed at reduced pressure, P, of 23 psig. Containment was pressurized t

and allowed to stabilize for 4.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. An acceptable leakage rate was measured 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> later using the mass point method. The verification test was begun immediately. Four hours into the verification test, the containment leakage rate decreased. As a result of the deceased leakage rate, the verification test was declared unacceptable eleven hours after it was begun. The verification leakage rate went below the minimum acceptanca limit of -25%.

A second ILRT was initiated immediately after securing the induced leak of the first verification test. The containment leakage rate was measured over the next six hours using the reduced test duration method as described by the Bechtel Topical Report, BN-TOP-1.

The leakage rate was also calculated with the mass point method. Again, a verification test was begun. After five hours, the verification leakage rate was stable and within the acceptance band of 25%. This was true using both calculation methods, BN-TOP-1 and the mass point method.

The first leakage rate measured is the leakage rate being reported for Unit 1 containment.

Because the leakage rate changed (decreased) it was necessary to measure the containment leakage rate a second time in order to demonstrate that the leakage rate could be measured accurately. That is to say, the second ILRT was used as a new base line for

"'e verification test.

The personnel airlock is believed to be the cause of the anomaly. Pressure was found in the airlock at the conclusion of testing. The decrease in the leakage rate occurred once the l

airlock had reached equilibrium with Containment.

l For a reduced pressure test,0.75 L as determined during preoperational testing,is t

0.11569 wt%/ day. The 1994 ILRT on Unit 1 containment yielded a least squares curve fit Lm of 0.659 wt%/ day and a corresponding 96 percent upper confidence level L m of d

t t

0.0685 wt%/ day. A valve lineup penalty of D 00074 wt%/ day must be added to L m 95% UCL.

t The final"AS LEFT" leakage rate at UCL including all penalties is 0.0772 wt%/ day while the l

"AS FOUND" leakage rate is 0.0998 wt%/ day (reference Appendix C).

ILRT Unit 1 Page 3 of 45 2.0 DESIGN INFORMATION 2.1 Containment Vessel Design The design parameters of the Unit 1 containment vessel have previously been described in references 6.1 and 6.2.

2.2 ILRT Instrumentation System The Integrated Leakage Rate Test Instrumentation System is designed to monitor containment parameters and calculate a leakage rate using the absolute method. Data read from the transducers is entered directly into a Hewlett Packard Model 1000 computer for reduction and analysis. Details of the test system are described in

~

~

reference 6.5. For the leakage rate test twenty-six resistance temperature detectors (RTD), ten humiters, one precision pressure gauge and one flow meter were used.

2.3 ILRT Pressurization System The containment was pressurized using Atlas Copco air compressors, after coolers and air dryers connected to Prairie Island's pressurization line. All air released from containment for the leakage rate test was vented to the Auxiliary Building and hence monitored by the Auxiliary Building ventilation radiation monitoring system. In addition, continuous air monitors (CAM) were positioned at the localized release path.

3.0 PRE-TEST CONSIDERATIONS 3.1 ILRT Instrumentation All instrumentation utilized during the ILRT was calibrated by vendors whose Quality Assurance Programs were verified by Northern States Power Company.

These instruments, all calibrated within six months of the test date, have calibration certification traceable to the NationalInstitute of Standards and Technology. Sensor calibration correction factors were then derived from the calibration curves.

Though not required by Technical Specifications, the containment fire detection system was temporarily modified by installing 12 photoelectric fire detectors in place of the existing ionization type. This was performed to avoid spurious fire alarms during periods when the containment was pressurized. No fire alarms were received during the duration of the test.

During the ILRT containment pressure was monitored by Control Room personnel via the containment wide range pressure channels. The six safeguards containment pressure channels were defeated by opening the test jack switches in the analog

(

protection racks.

ILRT Unit 1 Page 4 of 45 3.2 Venting and Draining Criteria The following criteria was used to determine the ILRT valve lineup:

A.

From 10CFR50 Appendix J:

1.

"Those portions of the fluid systems that are part of the reactor coolant pressure boundary and are open directly to the containment atmosphere under post-accident conditions and become an extension of the boundary of the containment SHALL be opened or vented to the containment atmosphere prior to and during the test."

2.

" Portions of closed systems inside containment that penetrate containment and rupture as a result of a loss of coolant accident SHALL be vented to the containment atmosphere."

3.

"All vented systems SHALL be drained of water or other fluids to the extent necessary to assure exposure of the system containment isolation valves to containment air test pressure and to assure they will be subjected to the post-accident differential pressure."

4.

" Systems that are required to maintain the plant in safe condition during the test SHALL be operable in their normal mode, and need not be vented."

5.

" Systems that are normally filled with water and operating under post-accident conditions, such as the containment heat removal system, need not be vented."

B.

Other Criteria:

1.

Allisolation valves which shut automatically on a safeguards signal, which are shut manually as a part of the post-accident safeguards sequence, or which are normally shut during power operation (except venting lineups)

SHALL be shut during the ILRT.

2.

Lines penetrating containment are to be vented to the outside atmosphere if, they are normally or potentially vented during power operation or if they could be vented after some phase of the safeguards sequence. Normally closed systems outside of the containment SHALL also be vented unless they are Seismic Class 1.

Pressure vessels inside containment vented to containment atmosphere during the ILRT:

1.

RCS via Pressurizer Vent 2.

Reactor Coolant Drain Tank 3.

Pressurizer Relief Tank 4.

Power Operated Relief Valve Accumulators (2 trains) 5.

No.11 a 12 SI Accumulators 6.

No.11 & 12 Steam Generator Snubber Accumulators Containment H Monitor Calibration Gas Bottles 7.

2 D.

Electrical penetration venting The electrical penetrCons were depressurized to 10 5 psig prior to the ILRT. Any penetration indicating greater than 15 psig would require investigation. During the ILRT, no electrical penetrations were observed to be greater than 15 psig. The nitregen supply to the electrical penetrations and the airlock electrical penetrations were isolated and vented to atmosphere.

E.

Water levelin the following equipment is recorded before and after the ILRT:

1.

Reactor Coolant Drain Tank 2.

Pressurizer Relief Tank 3.

Containment Sump A 4.

Containment Sump B 5.

11 & 12 Steam Generator 6.

Pressurizer During performance of the June ILRT the levelin Sump A increased 5 inches. The pressurizer level increased 1.2%, and the Pressurizer Relief Tank Level decreased 1.2%. This change in volume (0.00131 'wt%) will be included as an added penalty in the final leak rate reported.

i 3.3 Local Leak Rate Testing Program The local leak rate test program was performed during each refueling outage as required by 10CFR50, Appendix J and Prairie Island Technical Specification 4.4.A.

A summary of Type B and C test results, obtained since the last ILRT report was submitted, are in Appendices A, arid B. The 1994 final results reflect the as-left conditions of containment a?.sr the 1994 Unit 1 Type A test. Local leak rate valve repairs are summarized in Appendix C.

The acceptance criteria for type B & C test are as follows:

A.

If the totalleakage of alllocalleakage testing exceeds 60% of La, repairs and

(

retests SHALL be performed to reduce leakage below that value.

I pingp/ misc /gruber/ilrt

ILRT l

Unit 1 Page 6 of 45 B. Total leakage past isolation valves in systems in the Auxiliary Building Special Ventilation Zone (ABSVZ) SHALL be less than 0.1 wt%/ day at Pa-C. Totalleakage past isolation valves in systems exterior to both the ABSVZ and the Shield Building SHALL be less than 0.01 wt%/ day at Pa.

D.

Airlock leakage SHALL be less than 1% of the La at 10 psig for the door inner gasket tests and less than 5% of the La at 46 psig for overall airlock tests.

3.4 Containment inspection A generalinspection of the accessible interior and exterior surfaces of the containment and related components was performed prior to the ILRT as required by 10CFR50, Appendix J, Section V. There was no evidence of structural degradation. The inspection revealed no pressurized containers, fire hazards or containment wall growth interferences. In general, the containment was very clean. The annulus area was also inspected for wall growth interferences; none were found.

4.0 GQEDUCT OF ILRT 4.1 Acceptance Criteria of Type A Test The leakage rate, Lt at reduced pressure P,is calculated as follows:

pingp/ misc /gruber/ilrt I

Unit 1 Page 7 of 45 4.2 Iype A Test and Verification Test Results and Conclusions The Unit 1 Type A test was performed using the Mass Point Calculational Technique.

The test data displayed acceptable results after five hours of testing using the Mass Point Technique. The least squares leakage rate, L m, at the final data point after t

24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of data collection was 0.0659 wt%/ day with a corresponding L m at the t

95 percent upper confidence level equal to 0.0685 wt%/ day.

Upon completion of the Type A test, a supplemental test was performed to verify the validity of the Type A test. For the verification test, a leak of 1.20 L was introduced t

through a calibrated flow meter. Four hours into the verification test, the leakage rate began decreasing. This continued until the measured leakage rate went below the minimum acceptance criteria. After 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br />, the verification test failed when the measured leakage rate went below 75% of the calculated leak (see Figures 5 - 8 and Table 2).

',a immediately after the induced leak of the first verification test was isolated, a second Type A test was initiated. The second Type A test was a short duration test using the method described in BN-TOP-1. The leakage rate was also measured using the Mass Point method as a check on the BN-TOP-1 method. After six hours, a stable leakage rate was measured: 0.0056 wt%/ day (95% Upper Confidence Level), see Figures 9 -

13 and Tables 3 and 4.

At the conclusion of the second Type A test, a second verification test was initiated. To verify that the flow meter used to measure the induced leak was accurate, a second calibrated flow meter was installed in series with the first meter. Because this second meter did not have the range of the first, the induced leak was chosen at 0.86 L. Both t

flow meters displayed the same flow. After five hours the composite leakage rate exhibited very good correlation to the acceptance band (see Figures 14 - 18 and Tab!cs 5 and 6):

0.0896 wt%/ day 5 Le s 0.1547 wt%/ day Once the second verification test was over, depressurization of the containment was begun. At this time, the two airlocks were vented. A significant amount of pressure was found in the personnel airlock. It is believed that the higher than usual leakage rate measured by the first Type A test was caused by the personnel airlock slowly pressurizing. The airlock finally reached equilibrium with containment at four hours into the first verification test. Once the airlock was at equilibrium the containment leakage rate decreased. This caused the failure of the first verification test.

With the exception of the failure of the first verification test, as explained above, review of the test data shows smooth and stable trends. No instruments failed. Ambient weather conditions were favorable. It was a successful Type A test.

5.0 SPECIAL TESTING 5.1 Shield Building Testing Section IV, paragraph B of 10CFR50, Appendix J,"Special Testing Requirements" and Technical Specification 4.4.A.6 require testing of multiple barrier containments. Unit 1 Shield Building is functionally tested at monthly intervals according to NSP Surveillance Procedure SP 1073. The Shield Building is functionally tested when each redundant train of the special ventilation system is tested to determine if it meets drawdown performance computed for the test condition with 75% of the Shie:d Building inleakage specified in Technical Specification Figure TS 4.4.1. None of these monthly tests on Unit 1 Shield Building have failed to meet the acceptance criteria due to Shield Building degradation.

5.2 Auxiliary Building Testing Technical Specification 4.4.A.6 requires retesting of the Auxiliary Building Special Ventilation Zone (ABSVZ). Leak tightness of the ABSVZ is verified at quarterly intervals when each redundant train is run to determine if it can produce an acceptable negative pressure in the zona within six minutes with an opening in the bcindary of at least ten square feet. None of these quarterly tests have failed to meet the asceptance criteria.
