2.0 PURPOSE:

The purpose of this report is to document Containment Integrated Leakage Rate Testing (CILRT) at Virginia Power Surry Power Station, Unit Two, conducted during May 1991 and to provide a summary of the Local Leakage Rate Tests (LLRT's) performed on Unit Two containment penetrations since the last Unit Two CILRT which was performed in November 1986.

This report is submitted as required by 10CFR50, Appendix J, Section V.B. to demonstrate that the primary reactor containment has met the containment leakage test requirements set forth in 10CFR50, Appendix J, Section III.A.5.(b). (2) .

2.1

3.0 UNIT DESCRIPTION:

Surry Unit MWth. Two 2, Docket Two is a Pressurized Water Reactor rated at 2441 similar units (Unit 1, Docket No. 50-280 and Unit No. 50-281) are owned by Virginia Power and are located in Surry County, Virginia.

The containment structure is a steel-lined, reinforced concrete cylinder with a hemispherical dome and a reinforced concrete foundation mat. Containment volume is 1.8 x 10 6 ft 3

Containment design pressure is 45 psig which is sufficient to withstand the internal pressure from a design-basis accident (DBA). It has been calculated that the peak accident pressure and temperature from a DBA are 44.98 psig and 285°F respectively .

SUMMARY

4.1 CONTAINMENT INTEGRATED LEAKAGE RATE TEST (CILRT):

The Unit Two 1991 CILRT was successfully completed on May 27, 1991. The final upper confidence limit (UCL) leakage, including the required penalties, was . 041887 wt

%/day. The test results demonstrated that the integrity of the containment structure satisfied the criteria set forth in 10CFR50, Appendix J, Paragraph III.A.5. (b). (2).

As part of preparations for the CILRT, component cooling water to the containment air recirculation fans was secured approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months prior to pressurization.

Securing component cooling water causes containment air temperature at the start of the CILRT to be close to the containment structural temperature thereby reducing the containment stabilization time.

A one point in-situ calibration check performed on the temporary moisture analyzers ( 5) installed in containment revealed that one moisture analyzer (#8) was reading erratically. It was decided to remove the moisture analyzer computer point from the CILRT computer program.

The CILRT computer program automatically reassigns the weight factor for the rejected analyzer to the other

moisture analyzers in that zone. As required by Attachment 2 of 02-NPT-CT-101, Reactor Containment Building Integrated Leak Rate Test, a Instrumentation Selection Guide (ISG) recalculation was performed to determine the minimum test duration. The minimum CILRT duration, minus the one rejected sensor, was 11.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months .

As part of the containment leakage rate test program, an air test is performed every refueling on the service water side of the Recirculation Spray Heat Exchangers (RSHX). Air tests are performed to verify integrity of service water piping and components associated with each RSHX. The test of the "C" RSHX revealed excessive leakage from a Service Water (SW) check valve gasket located inside containment. A replacement gasket was not available at the time (prior to pressurization for CILRT), so the lines were blanked in Safeguards outside containment and a vent was opened inside contai11.ment. No CILRT penalty was added for blanking these lines because the RSHX Service Water piping and components inside containment are considered a closed system. Because it is a closed system, the valves assoc.:iated with these penetrations are not required to be Type c tested.

Following completion of the CILRT, the check valve gasket was replaced and a satisfactory air test was performed to verify leak tight integrity of "C" RSHX SW piping and components prior to unit startup.

SUMMARY

(CONTINUED):

On May 24, 1991, a final containment walkdown was performed at 0045 hours5.208333e-4 days 0.0125 hours 7.440476e-5 weeks 1.71225e-5 months . Containment pressurization commenced at 0220 hours0.00255 days 0.0611 hours 3.637566e-4 weeks 8.371e-5 months on May 24, 1991 and continued until 1311 hours0.0152 days 0.364 hours 0.00217 weeks 4.988355e-4 months on May 24, 1991 with a peak containment pressure of 61. 366 psia. During pressurization, the "C" containment air recirculation fan tripped off line on high current overload at 0300 hours0.00347 days 0.0833 hours 4.960317e-4 weeks 1.1415e-4 months . The "B" containment air recirculation *tan and the "A" containment air recirculation fan were secured prior to exceeding 200 amps, at 0321 hours0.00372 days 0.0892 hours 5.30754e-4 weeks 1.221405e-4 months and 0530 hours0.00613 days 0.147 hours 8.763227e-4 weeks 2.01665e-4 months respectively. After the "A" containment recirculation fan was secured, a remote fire watch for containment was established in accordance with Attachment 14 of 02-NPT-CT-101.

The containment temperature stabilization criteria in Attachment 7 of 02-NPT-CT-101 was met at 1749 hours0.0202 days 0.486 hours 0.00289 weeks 6.654945e-4 months . The CILRT started at 2330 hours0.027 days 0.647 hours 0.00385 weeks 8.86565e-4 months on May 24, 1991. During the course of the pressurization period, stabilization period, and throughout the CILRT, extensive leak checks were performed by inspecting potential leakage paths such as the mechanical penetration area in the Auxiliary Building, the electrical penetration area, the personnel and equipment air locks, Safeguards, Safeguards Valve

Pit, Fuel Building area and Containment Purge MOV' s located outside containment. Two electrical penetrations indicated a small increase in pressure and minor leakage was observed through the inside of Containment Purge Supply MOV's using an LMC located outside containment.

No other significant leakage paths were discovered.

The CILRT leakage test was successfully completed at 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months on May 25, 1991 with a UCL leakage of .041452 wt

%/day. With the Type C test penalties added to the test result, the final leakage was 0.041887 wt %/day.

In accordance with O-NPT-CT-107, Data Collection During Type A Test, the levels of tanks and vessels associated with systems in containment were monitored hourly during the entire CILRT. Overall change in containment volume was an increase of approximately 279 ft 3 due to changes in tank/vessel/sump levels during the CILR~. This equates to having to subtract .000155 wt %/day from the CILRT results which results in a final leakage of .041732 wt %/day. Taking a conservative approach, this change in net free volume was not factored intQ the final CILRT results.

4.2 SUPERIMPOSED VERIFICATION TEST:

The superimposed verification test was started at 0039 hours4.513889e-4 days 0.0108 hours 6.448413e-5 weeks 1.48395e-5 months on May 26, 1991 with a leakage of approximately

5. 00 SCFM on the flow meter. The. stabilization period for the superimposed verification test ended at 0239 hours0.00277 days 0.0664 hours 3.95172e-4 weeks 9.09395e-5 months on May 26, 1991. At that time, leakage calculations were started. The superimposed verification test then continued for approximately 17.75 hours8.680556e-4 days 0.0208 hours 1.240079e-4 weeks 2.85375e-5 months . The final superimposed leakage rate value was .114287 wt

%/day and satisfactorily met the acceptance criteria of 02-NPT-CT-115, Superimposed CILRT Verification Test.

Depressurization of containment commenced at 2250 hours0.026 days 0.625 hours 0.00372 weeks 8.56125e-4 months on May 26, 1991 and was completed at 0752 hours0.0087 days 0.209 hours 0.00124 weeks 2.86136e-4 months on May 27, 1991. The post CILRT containment inspection was completed at 1238 hours0.0143 days 0.344 hours 0.00205 weeks 4.71059e-4 months on May 27, 1991.

4.3 LOCAL LEAKAGE RATE TESTS (LLRT):

Local leakage rate testing of containment penetrations was conducted as required by 10CFR50, Appendix J and Technical Specifications using approved station procedures. In accordance with 10CFR50, Appendix J, Section V.B.3, Attachment 8.1 summarizes all the local leak rate tests that have been conducted since the performance of the last Unit Two CILRT (November 1986) .

4.4 CONCLUSION

Since all applicable acceptance criteria were met, the normal CILRT schedule as specified in 10CFR50, Appendix J, paragraph III.D.l(a) should continue. The next CILRT will be performed during the 1994 Refueling outage in conjunction with the ASME Section XI second interval 10 year inservice inspection.

6.0 TEST DESCRIPTION:

6.1 EQUIPMENT USED The containment was pressurized utilizing a temporary air pressurization rig which tied into the containment purge ventilation duct. The rig consisted of 8 diesel driven oil-free air compressors, 2 aftercoolers and 1 air dryer.

The rig was capable of supplying up to 10,000 SCFM of air to containment during the pressurization phase. Cooling water for the aftercoolers and air dryer was supplied by the station I s chilled component cooling system. The pressurization rig was satisfactorily checked out prior to pressurization in accordance with Attachment 4.0 of 02-NPT-CT-101.

Containment temperature was moni tared throughout the Type A Test by the use of 22 permanently mounted Resistance Temperature Detectors (RTD's) whose output is fed to the P250 computers. The normal span of these RTD's was changed for the test by utilizing a temporary resistance bridge that was installed on the P250 computer. The span was narrowed to 60-120 degrees Fahrenheit to allow for greater sensitivity in recording containment temperature.

Station computer input calibration procedure, 2-CAL-753, was performed on each RTD input signal to each units P250 computer. A decade box was temporarily installed on the P250 computer which simulated the resistance reading for each RTD inside containment. The computer was then checked to ensure that the proper output for each RTD was obtained when the resistance was varied. A three point calibration at 60 degrees, 90 degrees, and 120 degrees Fahrenheit was performed within 6 months on the RTD's to ensure their accuracy. A one point local verification check of the RTD' s using a standard traceable to NIST was performed prior to the CILRT using station procedure o-NPT-CT-103, "Calibration Check For RTD' s and Moisture Analyzers".

6.1

6.1 EQUIPMENT USED {CONTINUED)

Containment dewpoint temperature was monitored by five (5) Ondyne moisture analyzer probes located throughout containment. Readout devices with a tie-in to the P250 computers were located in the electrical penetration area. The Ondyne analyzers use the principle whereby the temperature of the detecting surface on the probe is cooled by a thermoelectric device to the point where condensation forms. When condensation is detected, cooling is controlled to hold the surface at the condensation temperature and then the surface temperature is measured using a platinum RTD. This surface temperature is the dewpoint temperature of the air next to the probe.

The moisture analyzers were calibrated within six months of the CILRT by the vendor and their accuracy was certified as being traceable to NIST. An additional one point check was performed for each analyzer using station procedure O-NPT-CT-103.

Containment pressure was monitored by the use of two (2)

Menser Quartz manometers. These manometers use the Containment Leakage Monitoring (LM) system through leakage monitoring connections on the 13' level of the Auxiliary Building. The signal from these manometers was fed into the P2 5 o computers. The manometers were calibrated within six months of the CILRT by the original manufacturer with the accuracy being certified as being traceable to NIST.

A Hastings linear mass flowmeter was used to monitor flow for the superimposed verification test which followed t:he Type A Test. The flowmeter measures flow without any corrections being needed for pressure and temperature.

Flow is displayed and totalized at the flowmeter which is installed in the LM system on the 13' level of the Auxiliary Building. The LM piping then ties into the Service Air (SA) piping penetration which is vented inside containment. The flowmeters accuracy was certified as being traceable to NIST by the original manufacturer within six months of the CILRT.

Attachment 6. 1 lists pertinent information - for the instrumentation that was used during the CILRT.

6.2

6.2 CILRT PROGRAM - P250 COMPUTER The ILRT program on the P250 computer gathers and logs the required data during the CILRT. The data is printed out in log format every 10 minutes and is then input into the PC ILRT program.

The ILRT program on the P250 computer consists of three sub-programs. The programs are run on both units P250 computers during the Type A Test. The program on Unit one's computer would be used as backup if Unit Two's computer fails. The three programs are ILRTMANO, ILRTDAT2, and ILRTPRT2.

The ILRTMANO program is used to convert the BCD output of the quartz manometers into floating point numbers. The ILRTMANO program reads six BCD digits for each quartz manometer via a direct channel read and converts these BCD signals into floating point values which are placed in calculated points U0962 and U0963 of the P250 computer. Each quartz manometer is scanned on a two second frequency.

The ILRTDAT2 program uses the 22 containment RTD readings, 5 moisture analyzer readings and 2 pressure readings to apply the appropriate weight factors and to perform sensor validity checks. These values are obtained from the P250 Average and Integrate (A&I) program which calculates a simple average for each of the twenty-nine (29) sensors by summing the instantaneous readings taken during a ten minute period and dividing the totals by the number of readings taken. The RTD's and moisture analyzers are scanned every 20 seconds by the A&I program.

The ILRTDAT2 program also performs sensor checks by checking the difference between the ten minute averages of sensors within the same zone against a maximum limit.

When the maximum limit is exceeded, the program notifies the operator via an.error message printed out on the alarm typewriter to check the zone. If a sensor has malfunctioned, the operator can direct the program to stop scanning the faulty sensor and to reassign the failed sensors weight factor to the remaining sensors in its zone.

6.3

CILRT PROGRAM - P250 COMPUTER (CONTINUED) 6.2 ILRTDAT2 prints three sets of containment data every ten minutes. First, the instantaneous value of each sensor is printed on the trend typewriter. These data points are used by the Test Engineers for trend evaluation.

Second, the containment averaged parameters based on the ten minute averages of sensor readings are printed to the alarm typewriter. Third, the containment averaged parameters based on instantaneous sensor readings are printed to the alarm typewriter. The containment averaged parameters (those based on instantaneous sensor readings) and time are input to the PC ILRT for the actual leak rate calculation. These data are also stored on the P250 disk drive for up to 25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months .

The ILRTPRT2 program prints a formatted log of the containment averaged data that is calculated and stored on disk by ILRTDAT2. ILRTPRT2 is executed automatically by ILRTDAT2 either after 25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months of. data are collected or when a print request flag has been set. ILRTPRT2 can also be executed manually from the P250 programmer's console. The log contains containment averaged data based on both time averaged sensor readings and instantaneous sensor readings .

6.3 CILRT PROGRAM - PC COMPUTER The CILRT program on the PC computer is used to calculate and plot the change in containment air mass versus time.

Input data for the program is obtained from the plant process computer (P250) data collection program. The variables which are input into the PC program are time, containment pressure, dewpoint temperature and containment temperature.

An auxiliary PC program (CONVERT} is used to transfer the PC ILRT input data automatically from the P250 printed output. CONVERT reads the captured alarm typewriter output. It discards all information except the tabular listing of containment averaged data based on instantaneous sensor values. The containment data is then reformatted and stored in a data file suitable for iriput to PC ILRT.

PC ILRT has options for performing various functions which enable the user to calculate results, list data set members, input additional data set* members, modify existing data set members and to delete data set members which are not needed .

6.4

6.3 CILRT PROGRAM - PC COMPUTER (CONTINUED)

In the calculation mode, the user has the option of performing either mass point, total time or point-to-point analysis. Mass point was used for this test because Amendment No. 120 to Technical Specifications, which was approved by the NRC on May 24, 1988 modified Section 4.4 to reflect the use of the Mass Point method for calculating containment leakage rates.

The Mass Point method calculates the air mass at a series of points in time, and plots it against time. The air mass in containment was calculated using pressure, temperature, and dewpoint data which was collected by the P250 computers. Air mass is calculated using the ideal gas law formula. The formula is as follows:

M = 144 V (P-Pv)

R T Where: M =airmass, lbm P = total pressure, psia Pv = vapor pressure, psia R = 53.35 ft-lbf/lbm R (for air) 0 T = average containment temperature, R 0

V = containment free volume, 1.8 x 10 6 cu FT After the mass is calculated, the results are correlated as a function of time by using a least-squares-curve fit of the form:

M = At+B Where: M = estimated mass A= least squares slope - dM/dT B = least squares y - intercept - Mo The slope (A) and y-intercept (B) are used to calculate the leak rate. The leakage rate is calculated after the mass is plotted as a function of time using a least-square fit to determine the slope, A= dM/dT. Leak rate is expressed as the fraction of mass lost per 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months out of containment:

Leakage Rate= (dM/dT)/Mo x (-2400)

Where dM/dT is the slope of the mass least-square curve and Mo is they-intercept.

6.5 le

6.3 CILRT PROGRAM - PC COMPUTER (CONTINUED)

The sign convention is such that a positive leakage rate value is an indication of outward leakage. The uni ts for this value are in wt %/day.

A 95 percent confidence limit is calculated for each value using a Student's T distribution. The sum of the 95 percent confidence limit and leakage rate is the Upper Confidence Limit (UCL).

The output from the program will then print out the time, mass, measured leakage, estimated leakage, confidence limit and the Upper Confidence Limit for each data set .

6.6

ATTACHMENT 6.1 INSTRUMENTATION The following instrumentation-was calibrated and/or functionally verified within 6 months prior to the performance of this test and in accordance with 10CFR50, Appendix J.

7.0 TEST RESULT ANALYSIS 7.1 CILRT The CILRT was satisfactorily completed at 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months on May 25, 1991. The Mass Point method was used to analyze the data to ensure that containment integrity met the requirements of 10CFR50, Appendix J. Figure 7.1 and 7.2 show the trends of containment mass and UCL leakage during the CILRT. Attachment 7.5 lists the final CILRT results along with the required Type C penalties.

Attachment 7.1 and 7.2 list the input data and mass point CILRT results using instantaneous data from the plant process computer (P250).

7.2 SUPERIMPOSED VERIFICATION TEST The supplemental verification test was satisfactorily performed using 2-NPT-CT-115, "Superimposed Verification Test". Figure 7.3 shows a plot of leakage versus time for the verification test. Included on the plot are the upper and lower limits for the verification test results.

The equation used to ensure that the verification test was acceptable is:

(Lam + Lo - . 25La) ~ Le ~ (Lam + Lo + . 25La)

Where: Lam= Type A calculated leakage Lo = Superimposed leakage rate on containment Le = Leakage during verification test (computer)

La = Maximum allowable leakage Attachment 7.3 and 7.4 has a listing of the input data and test results for the verification test.

Subs ti tu ting actual test results, the above equation turns out to be:

(.039545+.0981-.025) ~ .114287 ~ (.039545+.0981+.025)

.112645 ~ .114287 < .162645 As shown above, Le falls within the upper and lower limits of the equation.

- 8.0 LOCAL LEAK RATE TESTS (TYPE BAND C)

Type Band C tests were performed on containment penetrations prior to the CILRT. The As-Found and As-Left test results for these penetrations are shown in Attachment 8 .1.

repairs were required, a. description is included.

If any Also included in Attachment 8.1 are Type Band C test results for tests which were performed since the last CILRT in November 1986.

The total As-Found Type Band C leakage value, using maximum pathway leakages, during the 1991 Refueling Outage was 680.99 SCFH which is above the maximum leakage of 0.6 LA (180 SCFH) as specified in 10CFR50, Appendix J, Section III.B.3.(a).

The majority of the As-Found leakage can be attributed to two penetrations. These two penetrations each had an inboard containment isolation valve leakage of 305 SCFH. The penetrations/valves were Penetration 38 (02-DA-TV-200A) and Penetration 33 (02-DG-TV-208A). The outboard containment isolation valves for these two penetrations (02-DA-TV-200B and 02-DG-TB-208B) had an As-Found leakage rate of 0.045 SCFH and 0.56 SCFH respectfully. Therefore, the maximum leakage that could have passed through these penetrations using the minimum pathway leakage criteria was 0.605 SCFH.

The total As-Found Type Band C leakage value during the 1991 Refueling Outage was 20. 38 SCFH when using the minimum pathway leakage criteria.

The corrective action taken to reduce the Type Band c leakage below the O. 6 LA value was to repair and/or replace valves which had leakage above the maximum allowable leakage specified in 02-0PT-CT-201, "Containment Isolation Valve Local Leakage Rate Testing" (Type C Containment Testing).

Following these repairs the final As-Left Type B and c leakage, using the maximum pathway leakage criteria, was 26 .17 SCFH which is well below the 0.6 LA value of 180 SCFH.

9.0 AS-FOUND CILRT ANALYSIS An As-Found analysis has been performed on the CILRT. The purpose is to determine what the actual .CILRT leakage rate would be if the CILRT had been performed at the beginning of the outage prior to any repairs to Type Band C penetrations.

The As-Found analysis is performed using the following criteria:

1) The leakage savings was calculated for each penetration that was repaired and/or replaced.

2) The leakage savings is the difference between the pre-repair minimum pathway and post-repair minimum pathway leakages.

3) Minimum pathway leakage is the lowest leakage of the inside or outside valve grouping for the penetration in question.

4) If there were no repairs or replacements, a zero leakage savings is assessed to the penetration.

5) If the post-repair minimum leakage is greater than pre-repair minimum pathway leakage, a leakage savings of zero is assigned to the penetration .

6) The net leakage savings (wt %/day) is added to the final CILRT test results.

An analysis was performed on those penetrations that are considered credible leakage paths during the first hour of the accident, prior to the containment returning to subatmospheric pressure. The penetrations identified by note 1 through 4 in Attachment 9 .1 are excluded as credible leakage sources. The analysis and technical justification for excluding these specific penetrations was approved by the NRC in correspondence dated November 21, 1988 (serial #88-787).

As noted in Attachment 9.1, the as-found CILRT leak rate was 0.045299 wt %/day which satisfies the acceptance criteria of 10CFR50, Appendix J.
