SUMMARY

2.1 TYPE A TEST The North Anna Unit 1 Containment Integrated Leak Rate Test (CILRT) was performed from March 9-11, 1981. The following is I a summary of activities prior to and during the performance of the test.

Pressurization for the Type A test was initiated at approximately 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> on March 9, 1981, after satisfactory completion of all test prerequisites, including walkdown of the interior and exterior of the containment building. After several problems I related to removal of H bus for maintenance were encountered and resolved (see Section 3), containment pressurization to 58.3 psia was achieved at approximately 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br /> March 9, 1981.

At 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> on March 10, 1981, containment temperature stabili-zation criteria were met and the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> leak rate test was I officially started. After approximately 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of data collec-tion, the overall leak rate had dropped to 0.66 La and continued to decrease until the twenty-fourth hour at which time it was less than 0.17 La.

At 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> on March 11, 1981, the mass pumpback verification test commenced.

SECTION 3 TYPE A TEST

~I 3.1 EDITED LOG OF EVENTS March 9, 1981 After all procedure initial conditions had been satisfied, the North Anna Unit Number 1 Containment Integrated Leak Rate I Test (CILRT) 1-PT-61.1 began at approximately 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br />.

Containment pressurization was accomplished with approximately 10,000 SCFM tf oil free air. Containment atmosphere was centrolled with containment recirculation air fans operating I with chilled water.

At 0905 hours0.0105 days <br />0.251 hours <br />0.0015 weeks <br />3.443525e-4 months <br /> pressurization of the containment was halted I when H bus was deenergized for maintenance. When H bus was deenergized, power to rad monitors RMS 159, 160, and 162 was lost. This caused the monitors to alarm, which led to I closure of MOV-HV102 and MOV-HV100A. These valves are located in the purge and exhaust line which was the line that was used for pressurization. Containment pressure at this time was 38 psia.

Containment pressurization was reinitiated at 1224 hours0.0142 days <br />0.34 hours <br />0.00202 weeks <br />4.65732e-4 months <br />.

I Pressurization continued until 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />, at which time all compressors were secured. The pressure at this time was 58.3 psia.

At 1724 containment recirculation air fan 1-HV-F-1A tripped 8 due to deenergizing H bus once again. An approved jumper was prepared to power 1-HV-F-1A from the J bus. At 2032 hours0.0235 days <br />0.564 hours <br />0.00336 weeks <br />7.73176e-4 months <br /> all I three (3) containment recirculation air fans were once again operable.

At 2215 hours0.0256 days <br />0.615 hours <br />0.00366 weeks <br />8.428075e-4 months <br />, 1-HV-F-lA once again tripped, this time due to I an overload on the feeder breaker used in the temporary jumper written to power 1-HV-F-1A from the J bus.

'E At this time it was decided to perform the type A test with 5 only two (2) operable containment recirculation air fans.

March 10, 1981 Containment temperature stabilization criteria were met at 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> on March 10, 1981.

After approximately 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of data collection, the overall leak rate had dropped to 0.66 La and continued to decrease until the twenty-fourth hour, at which time it was less than I .17 La.

commenced. At 0515 hours0.00596 days <br />0.143 hours <br />8.515212e-4 weeks <br />1.959575e-4 months <br />, approximately 394 lbm of air had  !

been pumped into the containment via the service air line. The I computer calculated mass increase was within the acceptable limit and the test was secured. At approximately 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> containment depressurization was started.

3.2 GENERAL TEST DESCRIPTION 3.2.1 Prerequisites In accordance with the North Anna Unit No. 1 CILRT l-PT-61.1, t , the following is a partial listing of prerequisites that are completed and documented prior to containment pressurization.

1. General inspection of the accessible interior and I exterior surfaces of the containment structure was performed.

I 2. All equipment and instrumentation that could be da.maged or destroyed by test pressure was removed or vented.

3. All instrumentation used for this test was calibrated.

4. Valve line-ups, as required, were completed including closure of the containment isolation valves.

5. Componen* cooling and chilled water systems were operable.

6. Plant computers w3re operational and programmed for the CILRT.

7. Instrument location verification tests were completed (see Appendix 3D).

8. The Official Log of Events book was established and available prior to initiation of the CILRT.

3.2.2 Equipment and Instrumentation Pressul-ization of the containment was achieved by utilization I of approximately 10,000 SCFM of oil free compressed air. Air was piped through two (2) aftercoolers in parallel and a refrig-erated air dryer. The dryer was sized to deliver air at approxi-I mately 100 psig with a 40* dew point. Instrumentation and valving were installed to maintain proper monitoring and control during pressurization.

I.

During the test, the variables necessary to quantify containment leakage were continually monitored using instrumentation which consisted of multiple resistance temperature detectors (RTD'S),

Foxboro dew cells, and two absolute pressure quartz manometers 5 (see Appendix 3C).

A gas totalizer in the service air system was used during the mass pumpback verification test. All test instrumentation I except for the gas totaliser is input into the plant computer for data acquisition and averaging.

3.2.3 Data Acquisition System The North Anna Unit 1 CILRT utilized a Westinghouse Prodac P250 to scan, log, and average, and analyze data received from the I. containment instrumentation.

I The p250 analog scan package reads all analog inputs in a pre-established manner, converts these readings into engineering units, and then stores these values for use by the plant engineers.

For the CILRT, the P250 plant computer monitored the following instrumentation:

Tyge Scan Rate (Sec.)

18 RTD's 20 5 Dew Cells 20 2 Quartz Manometers 2 Instantaneous values of the CILRT instruments were recorded every 5 minutes during the test period using the P250 digital I trend function on the operatcr's console.

A 10 minute time average of the 25 readings, calculated by the I p250 Average and Integrate (A&I) package, was used as input in the plant computer CILRT programs.

I The plant computer CILRT program consists of ILRTDATA, which runs ev_ry 10 minutes, collects A&I data for all the instrumentation, performs sensor validity checks, and calculates weighted average dew point temperature, vapor pressure, weighted average contain-I ment temperature, and containment air mass.

3.2.4 Data Resolution System After the appropriate data has been acquired and averaged utilizing the plant computer system, the results are manually input to a remote computer system for leak rate calculations.

I 3.2.4.1 Absolute Method Mass Point Analysis The absolute method of mass point analysis consists of calculating I air masses within the containment structure over a period of time from pressure, temperature, and dew point observations during the CILRT. The air masses are computed using the ideal gas law as follows:

M= (P-Pv) V (144) (Eq. 1)

RT where:

M = air mass, lb P = total pressure, psia Pv = average vapor pressure, psia I R = 53.35 ft lbf/lbm *R (for air)

T = average containment temperature, 'R V = containment free volume, ft3 The leakage rate is then determined by plotting the air mass as a function of time, using a least-squares fit to determine the slope, A (dm/dt) . The leak rate is expressed as a percentage of 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:

Leak Rate = A/B (-2400) (Eq. 2) where:

A = slope of least squares fit curve I B = y-intercept I The sign convention is such that an outward leak is positive and the units are in percent / day. The air mass is computed separately and the result is correlated as a function of time by means of a Icest-squares fit of the form:

I m = At + B (Eq. 3) l I The slope A and the y intercept B are then used in Equation 2 to determine the leak rate.

A 95 percent confidence interval is calculated using a student's T distribution.

The sum of leakage rate and the 95 percent confidence interval is I the t'CL. Therefore, the leak rate is less than the UCL with a probability of 95 percent.

The interval between approximately 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br /> March 9, 1981 to 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> March 10, 1981 represents the containment stabilization period.

The leakage rate analysis is performed by Virginia Electric and Power Company's (VEPCO) CILRT program. The input data for the VEPCO CILRT program are shown in Appendix 3E.

The absolute method mass point analysis was used to calculate the containment building leakage rate. The results (Appendix 3F) show I the UCL to be 0.01656 percent / day, which is within the acceptable limit of 0.07/ day (0.075 less t1:e Type C penalty for valves on systems not vented to the contai. ment) .
