SUMMARY

2.1 TYPE A TEST 2.1.1 Test Summary The Structural Integrity Test (SIT) for the containment was successfully i

completed on February 12, 1987.

The containment was opened and an entry was made to perform a general inspection.

The valve lineups required for the ILRT had been established for the SIT.

Pressurizatifon for the ILRT began at approximately 1027 hours0.0119 days <br />0.285 hours <br />0.0017 weeks <br />3.907735e-4 months <br /> on February 12,

-1987 with a fairly constant pressurization rate of 4.42 psi per--hour.

Pressurization was temporarily secured at 1810 hours0.0209 days <br />0.503 hours <br />0.00299 weeks <br />6.88705e-4 months <br /> due to a pressurization skid air dryer trip on high refrigerant. pressure.

This was ' caused by high chilled water temperature.

Pressurization of the containment was resured at approximately 2037 hours0.0236 days <br />0.566 hours <br />0.00337 weeks <br />7.750785e-4 months <br />.

The compressors were secured at approximately 2333 hours0.027 days <br />0.648 hours <br />0.00386 weeks <br />8.877065e-4 months <br /> on February 12, 1987 with a peak instantaneous pressure of 61.46 psia.

At 0405 hours0.00469 days <br />0.113 hours <br />6.696429e-4 weeks <br />1.541025e-4 months <br /> on February 13, 1987, the procedural temperature stabilization-criteria was satisfied.

Initial mass trends iodicated an unacceptable leakage

' nvestigations of all rate of. approximately 40 ~ lbm/hr.

Extensive leakage i

penetration areas were conducted.

These investigations revealed three O'

substantial leakage paths in the Recirculation Spray Syrtem (RSS).

Various minor leakage paths were also identified.

The three substantial leakage paths-in the RSS were as follows:

1.

Block Valve 2RSS*4 which isolates the non-seismic Demineralized Water System from the RSS..

2.

RSS Pump 2RSS*P21B shaft seal swagelok fitting.

3.

RSS Pump 2RSS*P21D shaft seal.

At approximately 1059 hours0.0123 days <br />0.294 hours <br />0.00175 weeks <br />4.029495e-4 months <br />, the leakage through 2RSS*4 war. isolated by closing the manual valve on the pump recirculation line. Mass trends from 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> to approximately 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br /> indicated an unacceptable leakage rate of approximately

- 22 lbm/hr.

The next substantial leakage path, which was the 2RSS*P21B shaft seal swagelok fitting, was isolated at approximately 1715 hours0.0198 days <br />0.476 hours <br />0.00284 weeks <br />6.525575e-4 months <br />. This isolation was performed by isolating the entire. loop outside of containment by closing the isolation valves.

The mass trend following this second isolation indicated an acceptable leakage rate of about 8 lbm/hr.

Section 3.3.2.4 contains the as-found and as-left leakage rates for the 2RSS*4 and 2RSS*P21B shaft seal swagelok fitting.

' Attachment 2.1A shows how the mass trend was affected by these two isolations.

The start time for the Type A Test was finally declared to be 1903 hours0.022 days <br />0.529 hours <br />0.00315 weeks <br />7.240915e-4 months <br /> on February 13, 1987 when the stability of all the containment parameter trends had recovered from the last isolation.

Temperature, dewpoint, and pressure data was continuously collected at one

(

minute intervals throughout the entire test period and were printed at 10 minute intervals.

The Type A Test was successfully completed at 1905 hours0.022 days <br />0.529 hours <br />0.00315 weeks <br />7.248525e-4 months <br /> on February 14, 1987

.V with a Mass Point Upper Confidence Limit (UCL-MP) of 0.037056 percent / day and a Total Time Upper Confidence Limit (UCL-TT) of 0.057981 percent / day, (See Section 3.3, Test Results).

Both the Mass Point and Total Time leakage rates were well below the 0.75 La acceptance criteria of 0.075 percent per day.

The Superimposed Leakage Verification Test was started at 2205 hours0.0255 days <br />0.613 hours <br />0.00365 weeks <br />8.390025e-4 months <br /> on February 14, 1987 when the stability of all the containment parameter trends _ had recovered from the imposed leakage rate perturbation. The Superimposed Leakage Verification Test was successfully completed at 0205 hours0.00237 days <br />0.0569 hours <br />3.38955e-4 weeks <br />7.80025e-5 months <br /> on February 15, 1987.

The results of the verification test satisfied the requirements set forth in Reference 2, (See Section 3.3, Test Results).

Depressurization of the containment commenced at 0240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br /> and was completed at 1045 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.976225e-4 months <br /> on February 15, 1987.

2.1.2 Conclusion The February 1987 Beaver Valley Power Station Unit 2 Type A Test was successfully completed, thus demonstrating the leak-tightness of the containment boundary.

The as-left leakage rate is well below the plant's procedural acceptance criteria, s

O 3.2-1

n (V) 3.2.2 Equipment and Instrumentation Pressurization of the containment was achieved by the utilization of a temporary system consisting of eight air compressors, two aftercoolers and a refrigerant air dryer. The system included adequate instrumentation and valving to maintain proper monitoring and control of the compressed air quality throughout the pressurization sequence.

The total capacity of the pressurization system was rated at approximately 10,200 standard cubic feet per minute (scfm).

Air was supplied to the containment through the plant's Leakage Monitoring and Containment Purge Systems.

The various containment parameters required to calculate containment leakage during the test were monitored using instrumentation which consisted of 18 resistanca temperature detectors, 5 dewpoint temperature sensors, and an absolute pressure quartz manometer. Pertinent data for the test instrumentation is listed in Attachment 3.2B, and the general locations of the temperature and dewpoint instrumentation are shown in Attachments 3.2C through 3.2F.

A rotometer was used to perform the Superimposed Leakage Verification Test.

3.2.3 Data Acquisition System The data acquisition system used for the Beaver Valley Power Station Unit 2 ILRT was the plant process computer.

O For the ILRT,.

the plant process computer monitored the following V

instrumentation:

M No. of Sensors Tenperature Detectors 18 Dewpoint Sensors 5

Quartz Manometers 2

i Instantaneous readings for each sensor were collected at one minute intervals and were printed every 10 minutes.

Input to the data analysis program was based on these collections. Each data set was time stamped.

(

)

3.2.4 Data Resolution System The recorded data was inputted to Stone & Webster Engineering Corporation's (SWEC) portable computer for data reduction and leakage rate calculations. Both the Mass Point and Total Time Analysis Methods were used to determine the leakage rates.

Absolute Method of Mass Point Analysis The Absolute Method of Mass Point Analysis consists of calculating the air mass within the containment structure, over the test period, using pressure, temperature, and dewpoint observations made during the ILRT.

The air mass is computed using the ideal gas law as follows:

M = 144V(P-Pv)

RT (Eq. 1) where M = air mass, lbm P = total pressure, psia Pv = average vapor pressure, psia R = 53.35 ft-lbf/lb, R (for air)

T = average containment temperature. R 3

V = containment free volume, 1,716,633 ft 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 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:

Leakage Rate = A/B(-2400)

(Eq. 2)

Where A is the slope of the least-squares curve and B is the y-intercept.

The sign convention is such that the leakage out of the containment is positive, and the units are in percent / day.

OV 3.2-3

i

)

The air mass is calculated and the result is correlated as a function of time by means of a least-squares curve fit of the form:

M = At + B (Eq. 3)

The slope A and.y-intercept B are ' then used in Equation 2 to determine the leakage rate.

A confidence interval is calculated using a Student's T distribution.

The sum of the leakage rate and confidence interval is the Upper Confidence Limit-Mass Point (UCL-MP).

Absolute Method of Total Time Analysis The Absolute Method of Total Time Analysis consists of calculating air lost from

-the containment, using pressure, temperature, and dewpoint observations made.

during the ILRT.

The containment air mass is computed using Equation 1.

The measured leakage rate at any time (t) is then determined by subtracting the mass at that time (Mt) from the initial mass (Mi) and dividing by the initial mass. The measured leakage rate is expressed as a percentage of containment 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:

Measured Leakage Rate = Mi-Mt (2400)

(Eq. 4)

U]

/

Mi (At)

The sign convention is such that leakage out of the containment is positive, and the units are in percent / day.

The calculated leakage rate is then determined by plotting the measured leakage rate as a function of time and then performing a least-squares curve fit of the measured leakage rate values as follows:

Calculated Leakage Rata = At + B (Eq. 5) where A is the slope and B is the y-intercept of the least squares curve'.

The sua of the calculated leakage rate and the confidence interval is the Upper Confidence Limit - Total Time (UCL-TT).

SECTION 4 V

LOCAL LEAKAGE RATE TESTS (TYPES B AND C) A summarizes the results of the Local -Leakage Rate Tests (ILRT's) data that was established to support the overall containment leakage testing program.- These LLRT's were performed by pressurizing the listed penetrations with air or nitrogen and either measuring leakage across the containment isolation valves boundary (Type C) or across the resilient seals (Type B).

The leakage rates that are listed in Attachment 4A are valve leakage rates, not penetration leakage rates.

Each penetration leakage rate can be obtained from site reference material.

The acceptance criteria for Types B and C leakage rate testing is in accordance with 10CFR50, Appendix J.

The combined leakage rate for all penetrations and valves, subject to Types B and C tests, is well below the acceptable leakage rate of 0.60 La.
