1. Completed structural integrity inspection of containment.  ;

1 3.2.2 Equipment and Instrumentation l Pressurization of the containment was achieved by the utilization of a temporary system consisting of seven diesel driven oil free air mip e rs, a water cooled aftercooler, and a refrigerant air dryer. %e system included adequate instrumentation and valving to maintain proper monitoring arx1 control of the ccupressed air quality throughout the pressurization sequence. %e total capacity of the pressurization system was 9000 SG M. Air was supplied to containment through the Containment Purge System.

We various containment parameters required to calculate containment leakage

! were ronitored usirq instrumentation which consisted of 18 resistance l temperature detectors, 5 dewpoint detectors, and 2 absolute pressure quartz Pertinent data for the test instrumentation is listed in manometers.

3.2.3 Data Acquisition System me data acquisition system used for IIRT was a comp 1ter controlled logging system which provided instantaneous raw sensor data.

For the IIRT, the Data Acquisition System monitored the following instrumentation:

Type No. of Sensors

'1bmperature Detectors 18 Dewpoint Sensors 5 Quartz Manmeter 2 Instantaneous readings for eadi sensor were collected and printed at 15 minute intervals. Input to the data analysis program was based on these collections.

Each data set was time stanped.

3.2.4 Data Resolution System he recorded data was inputted to Stone & Webster Engineering Cu putation's computer et wt am for data reduction and leakage rate calculations. S e Mass Point Analysis Method was used to deter.mine the containment leakage rate.

Absolute Method of Mass Point Analysis he Absolute K4 thod of Mass Point Analysis consists of calculatirq the air mass within the containment structure, over the test period, using pressure, temperature, and dapoint data obtained during the IIRP. 20 air mass is computed usirg the ideal gas law as follows:

144V(P-Pv)

{ M=

nr Where:

M = air mass, lhn P = total pressure, psia PV = average vapor pressure, psia R = 53.35 ft-lhn/lhu 'R (for air)

T = average containment temperature, 'R

• V = containment free volume, 1,716,633 cu. ft.

he leakage rate is then determined by plottirg air mass as a function of time, using a least p fit to determine the slope, A = dM/dr. W e leakage rate is expressed as a percentage of the air mass lost in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or symbolically:

Irakage Rate = A/B(-2400) 3.2-2

Where A is the slope of the least-squares curve ard B is the y-intercept. 'Ihe  !

sign convention is sx:h that the leakage out of containment is positive, ard ,

the units are in percent / day. l The air mm is calculated ard the result is carrulated as a function of time l by means of a least-squares curve fit of the form:

M = At + B A confidence interval is min 11ated usirq a Student's T distribution. 'Ihe sum of the leakage rate and confidence is the Upper Confidence Invel.

3.3.2.4 As Found Containment Condition - IIRT Inprovements In order to account for the affect of Im.al Isakage Rate Test (IIRT) repairs (made prior to the IIRP) on the "as found" condition of containment, an ,

analysis of IIRT results was performed.

- The "as found" minimm pathway leakage rate is reviewed against the "as left" i minimum pathway leakage rate for eadi LIRT per==Ls.ation. . If the perewation  ;

minimum pathway leakage rate is r M W because of repairs, maintenance, design L changes, etc., then the leakage rate inprovement is noted. 'Ihe total of all f these leakage rate improvements is the adjustment to the "as found" containment  :

condition. ,

The minimum pathway leakage rate for the following IIRP penetrations was .,

reduced as a result of repairs: '

Total Minimum Pathway Isakage Rate Inprwement = 2.29 SCF/D l Total Minimum Pathway Isakage Rate Improvement = 0.000033 Percent / Day' T

Adding this "as found" containment adjustment to the reported IIRT results yields the following results:

Item (Fu u::nt/Dav)

1. Total Reported IIRT Isakage Rate 0.040975 (See Section 3.3.2.1)

2. As Idund Containment Adjustment 0.000033

3. Total Containment Isakage Rate 0.041008 l 3.3-6

3.3.3 Conclusion No significant leakage paths were identified during the performance of the IIRP. Containment teq mrature stabilization significantly influenced the mass trend, which directly affected the containment leakage and the test duration.

At the start of the test, it appeared that the containment steel liner and concrete shell were at a lower tenperature than the containment atmosphere.

Therefore, during the performance of the test, the liner and shell absorbed heat from the containment ahnnaphere until the difference in teraperature was minimal. Without the assistance of forced ventilation, the tenperature stabilization took much longer than previously a ne d . No ventilation equipment was operated during the BVPC #2 November IIRP.

Consideration for future IIRr's will be given to use forced ventilation in containment prior to the start of the IIRT. One possibility might involve operation of one of more Containment Air Recirculation Fans for at least  !

48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to the start of pressurization, in an attenpt to equalize the liner and shell tenperature with the containrrent atmosphere. Also, the pressurization air tenperature should be maintained as close as possible to the containment atnosphere ten 1perature, even if the pressurization rate must be decreased.  ;

INSIMMENIATION SELECI'ICH GUIDE.

'Ihe Instrumentation Selection Guide (ISG) I far'mila is used to determine the ability of an instrumentation system to measure the integrated leakage of the reactor contai. Tent system. Instrumentation errors are cambined using a >

root-sum-square forFnla. The ISG is not AMai to the value of the calculated '

leakage rate, hit is used for instrument selection and loss of sensor criteria only. Mrec:urvJment system sensitivity values are used in the ISG fornula since  !

it is the change in the containment air mass, not the absolute value in mass, that is used to ca@ute leakage. The following is the information used to calculate the ISG.

IDCAL LEAKAGE PATE TESTS (TYPES B AND C) l Incal Irak Rate Testing (LIRT) of contairunent penetrations is perfonned on a l periodic basis (normally each refueling, but not oWing 24 months), in acconlance with 10 CFR 50 Appendix J ani Beaver Valley Power Station #2 7bchnical Specifications. 'Ihese IIRT's are performed by pressurizing the required penetrations with air or nitrogen and either measuring leakage across the containment isolation valves boundary (Type C), or across the resilient l seals (Type B). The combined leakage rate of containment pernhations subject l to IIRT's shall be less than 60 perant Ia, at a minimum test pressure of Pa.

l

! Additionally IIRT's (Total Volume Type B) are performed for each containment i airlock at 6 month intervals in accortlance with 10 CFR 50 Appendix J, and Beaver Valley Power Station #2 Technical Specifications.

Penetration No. 116 The "As-Found" leak test was performed March 28, 1992 with acceptable leakage rates measured; however, during the performance of 2BVT 1.47.3 " Check Valve Lift Test", the weight arms for check valve 2FPW*388 were binding when fully opened. MWR 8343 was written to repair the valve. The shaft plug seat was found not centered over the valve lxxty causing the birding. A 1/8" spacer was installed to center the plug. The "As-Inft" leak test and the " check Valve Lift Test" were performed on April 6,1992 with acceptable results obtained.

FIXHUH REFUELING IIX:AL LENKAGE RATE TEST REPAIRS Penetration No. 97-1 The "As-Found" leak test was performed Och 14, 1993. Due to low flow  ;

suspected through valve 2SSR*SOV129A-1, MR 23319 was written to inspect the valve.
