F. ACCEPTANCE CRITERIA  :

1. The maximum allowable leakage rate (L,) shall not exceed 1.0 weight percent of the  ;

contained air per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at a test pressure adjusted to 35 psig (P,). The allowable leakage rate (I,), at the test pressure (PJ shall not exceed the following:

I,= 1.0 wt. % [P,/P,]" .

I,= 1.0 [23.5/35]*

I,= .8194 ,

The ratio of pressures is based on gauge pressure, not absolute pressure as stated in the technical specification. The use of gauge pressure is more conservative, as explained in Engineering Evaluation No 485-90.

1. The measurement system installed inside containment prior to pressurization consists of two precision pressure gauges,30 resistance temperature detectors,10_ -  !

dewcells, and one multiplexer. These inputs are connected to a data acquisition system located outside containment which communicates with the Prime plant 'I computer. The arrangement of the Type A test instrumentation system is shown in ,

Figure 1. '

1 4

2. The multiple inputs for each parameter (pressure,'drybulb temperature, and dewpoint temperature) are combined using a weighted average based on the represented volume.The sensor readings are processed at 15 minute intervals for a minimum period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The sensor locations are shown on Figure 2.

3. All test sensors and flowmeters were calibrated prior to the ILRT in accordance with ANSI N56.8. In-situ checks were performed prior to the ILRT.

4. All sensors, except for one dewcell, performed acceptably during the ILRT. The one dewcell was removed from the calculations, and the remaining sensors were re-weighted according to procedure 666.5.007.

5. After completion of the Type A test, a known leak was superimposed on the containment through a calibrated flow sensor and measurements were continued.

The leakage rate calculated by the computer program during the verification test was compared to the leakage rate measured during the Type A test. Successful campletion of the verification test validated the test method and the instrumentation system.

H. TEST PROCEDURE

1. General Discussion During the pressurization phase, weighted pressure is monitored until the desired pressure is reached. Conditions are then allowed to stabilize for a minimum of four hours before the test is begun. Stabilization is reached when the weighted temperature meets the relationship in paragraph 2b of this report. Data scans are recorded every 15 minutes. The measured leakrate is closely monitored to detect high leakage. If detected, an evaluation will be made to determine the course of action to take. In addition, sensor data is reviewed to detect any malfunctioning sensors. Window calculations are performed, wrich record the leakrate over the last hour. This data is

reviewed periodically for trends which might affect the test results, a

C321-93-2153 Enclosure' 1 Page 4 The test is terminated when the measured leakrate and the UCL-95 leakrate are both within the allowable for the final 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, and the minimum time has elapsed. The final phase is the verification test, where a known leak is super-imposed on the containment and measured by the test equipment. A plot of the leakrate vs. time is printed.

2. Detailed Discussion

a. The pressurization phase took approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> to reach 24 psig. The rate of pressurization was limited by the compressors ability to deliver flow,

b. The stabilization phase took the minimum time of four hours. The slow pressurization rate allowed stabilization to occur quickly. The criteria for-temperature stabilization is when the test pressure is reached and the latest rate of ; ,

change of the weighted average contained air temperature averaged over the last . j hour does not deviate by more than 0.5 F per hour from the average rate of :

change of the weighted average contained air temperature averaged over the last -

four hours.  ;

73.164-72.698 = .1165 (four hour average) 4 72.798-72.698 = .100 I (last hour)

c. During the first few hours of the test, a high leakrate was observed. As a result,- l adjustments were made to reduce the leakage. Several valves were adjusted and -  :

the drywell sump was isolated. The test was then restarted, after about 26 hours3.009259e-4 days <br />0.00722 hours <br />4.298942e-5 weeks <br />9.893e-6 months <br />, ..

on January 28 at 1015 hours0.0117 days <br />0.282 hours <br />0.00168 weeks <br />3.862075e-4 months <br />. Subsequent to the test completion, a review of the  ;

results was made. It was determined that the repairs made during the test and the j induced leak were not detectable by the statistical model. For conservatism, the repairs were quantified and added to the UCL-95 value, along with the LLRT J

'~

leakage savings, Isolated Penetrations, and Drywell Sump Level Correction to - j determine the As-Found results. This evaluation is summarized in Engineering Evaluation No 314-93. The final ILRT test results are shown in Table 1 and .

Figure 3. i l

d. After completion of the Type .A test, a known leak was superimposed on the L containment through a calibrated flow sensor and measurements were continued. l The leakage rate measured during the verification test was compared to the sum of the induced leak plus the leakage rate measured during the Type A test.

Successful completion of the verification test validated the test method and the instrumentation system. The results are shown in Table 1.

I. METHODS OF ANALYSIS i The containment integrated leakage rate is calculated using the Mass Point data analysis technique. This technique reduces the data to a contained air mass.by application of the ideal gas law. The test data consists of a sequence of independent values of contained air mass. The assumption is made that the leakage rate is constant with time and the data is 3 analyzed using the method oflinear least squares regression. The slope of this line represents the rate of change of air mass to time, which is the leakage rate. The data is also analyzed statistically to determine the upper 95 percent confidence interval. The final reported leakage rate is the upper 95 percent confidence leakage rate. ] '

a. During 13R, Local Leak Rate Tests were performed in accordance with Appendix .;

J. The results by penetration are shown in Table 2. A summary is shown below.-  :

As-Found LLRT Total .

Several Valves failed the acceptance criteria, therefore, the Tech Spec Limit of l' 426 SCFH was exceeded. LER 91-002 was issued to address these concerns.

AS-Left LLRT Total  ;

The as-left total was 165.6 SCFH; the acceptance criteria of 255.60 SCFH was  !

met. 5

b. During 14R, Local Leak Rate Tests were performed in accordance with Appendix-  !

J. The results by penetration are shown in Table 3. A summary is given below. ,

As-Found LLRT Total l The total as-found LLRT's could not be calculated because the leakrate for MSIV i NSO4B could not be quantified. Therefore the Tech Spec limit was exceeded. l LER 92-013 was issued to address this failure.

As-Left LLRT Total The total max path as-left total was 127.5 SCFH, which is within the Tech Spec  :

limit of 255.6 SCFH.

Enclosure 1 Page 10-

c. During Cycles 12 and 13, several valves and the drywell airlock were tested.

Table 4 summarizes the tests. The valves were tested due to maintenance performed on the valves. The Airlock is tested _every 6 months, and whenever it is opened. There were no significant test results.

K.

SUMMARY

The calculated As-Found ILRT was .7704 wt%/ day vs the acceptance criteria of .8194 wt%/ day. The As-Found value was calculated conservatively because a _ leak was induced on the containment during the first test to try and find the source of the leakage.The affect of this induced leak was not removed from the calculation of As-Found results since it was below the acceptance criteria with this factor included.

The As-Left test results were .4006 wt%/ day compared to the acceptance criteria of

.6146 wt%/ day.

The verification test was performed in accordance with ANSI /ANS 56.8. Paragraph J3 of this report shows that the requirements of 56.8 were met, thus verifying the test -

instrumentation.

The As-Found LLRT results for both 13R and 14R exceeded the Tech Spec limit. LER's were issued as re. quired. ,

The As-Left LLRT results were below the acceptance criteria for both 13R and 14R. 1 Therefore, plant startup was allowed per Tech Spec requirements.

Periodic Local Leak Rate Tests were performed during Cycles 12 and 13 for Tech Spec  ;

Surveillances, forced outages, maintenance, or modifications. No significant results were  ;

found.

• a REPORT 1 SECONDARY CONTAINMENT LEAK RATE TEST RESULTS Secondary Containment Leak Rate Tests were performed in accordance with 10CFR50 and Oyster Creek Technical Specifications prior to the start of refueling outages 13R and 14R. The acceptance criteria of the test is satisfied if the Reactor Building is capable of maintaining a vacuum equal to or greater than .25" H2 O with a Standby Gas Treatment System flowrate of 2600 CFM i 260 CFM.

The results of the initial test prior to 14R did not meet the acceptance criteria for the Reactor Building vacuum. Minor repairs were made to door seals on the Reactor Building and the test was reperformed. The results met the acceptance criteria for both flow and vacuum.

l The results of the tests are summarized below:
