2.0 PURPOSE The purpose of this report is to document containment leak rate testing at Surry Power Station Unit 1 conducted during June 1988 and to demonstrate that the primary reactor containment has met the containment leakage test requirements of 10CFR50 Appendix J (Reference 1.1).
As discussed in Section 9 an As-Found Type 1A 1 test analysis was also performed to determine leakage savings. This analysis includes the leakage savings from those penetrations that are considered credible leakage sources during the first hour of the accident. Specific penetrations, as described in Section 9, have been excluded as credible leakage paths.
2.1
3.0 UNIT DESCRIPTION Surry Unit One is a Pressurized Water Reactor rated at 2441 MWth.
Two similar units (Units 1 and 2) are located at the site 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 (OBA).
It has been calculated that the peak accident pressure and temperature from a OBA are 44.2 psig and 285 degrees Fahrenheit respectively.

SUMMARY
4.1 TYPE A TEST Unit One 1988 CILRT was successfully completed on June 26, 1988.
The final Upper Confidence Limit (UCL) leakage result for the test was 0.02785 wt%/day.
The test results demonstrated that the integrity of the containment structure satisfied the criteria in 10 CFR 50 Appendix J, Paragraph III.A.(b).(2).
On June 23, 1988 a final Inspection Walkdown was performed at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br />.

During the course of the stabilization period and throughout the CILRT, walkdowns were performed on various areas to identify any possible leakage paths. Six vented penetrations in the Auxiliary Building were identified as leaking past their open Leakage Monitoring connections (LMC).
The total leakage for these penetrations was quantified as 13.26 SCFH.
The start of the CILRT leakage Test period was 1548 hours0.0179 days <br />0.43 hours <br />0.00256 weeks <br />5.89014e-4 months <br /> on June 24, 1988.
Extensive investigations of all penetration areas were conducted and data (temperature, dewpoint, and pressure) was collected throughout the entire test period.
The CILRT leakage period was successfully completed at 1608 hours0.0186 days <br />0.447 hours <br />0.00266 weeks <br />6.11844e-4 months <br /> on June 25, 1988 with a UCL leakage of 0.02785 wt%/day.
With the Type C test penalties added to the test results, the final leakage was 0.03145 wt%/day.

4.3 CONTAINMENT LINER TEST CHANNELS A general inspection of the accessible interior surfaces of the containment structure was performed, as required by 01-PT-16.3, prior to the Type A test.
This inspection is performed for the purpose of identifying evidence of deterioration in the containment liner which may affect the containment integrity.
During the walkdown, a leak-chase channel test plug was discovered missing along the interior \\'Jall between 11A 11 and 118 11 Loop Rooms.
No other plugs were discovered missing during the walkdown which covered the readily-accessible interior surface of containment.
While performing other Type*A related activities, using scaffolding that
\\'1as erected for other containment work, several normally inaccessible areas of the liner were able to be examined for missing channel test plugs.
Two leak-chase channel test plugs were discovered missing.
One was located in the 4.2
4.3 CONTAINMENT LINER TEST CHANNELS (CONT'D) dome of containment near the Recirculation Spray Ring and the other was located along the interior wall outside of 11 8 11 Steam Genei~ator cubicle approximately thirty feet above floor level. There were no other plugs discovered missing during the limited inspection of inaccessible areas.
The liner inspections did not identify any evidence of containment liner deterioration which could affect containment integrity.

5.3
6.0 TEST DESCRIPTION 6.1 EQUIPMENT USED The containment was pressurizrd utilizing a temporary air pressurization rig which tied into containment ventilation ductwork.
The rig consist.ed of 7 diesel driven oil-free a.ir compressors, 2 aftercoolers and 1 air dryer.
The rig was capable of supplying up to 10,000 SCFM to containment during the pressurizatior. phase.
Cooling water for the aftercoolers and air dryer was supplied by the stat.ion 1s chilled component cooling system.
The pressurization rig was satisfactorily checked out prior to pressurization in accordar.ce with.7 of Ol-PT-16.3 (Reference 1.3).
Containment temperature was monitored throughout the Type A test by the use of 22 permanently mounted RTDs whose output is fed to the P250 computers.
The normal span of these RTDS 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 calibration procedure 2-TCAL-664 was performed on each RTDs 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 program 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 for the RTDs to ensure accuracy and sensitivity reqirements were met.
A one point local verification check of the RTDs using a standard traceable to N~S was performed prior to the the Type A test using station procedure 01-PT-16.30.
This check ensures that the reading from the P250 computer corresponds to the actual temperature by the RTD.
6.1
6.1 EQUIPMENT USED (CONT'D)
_ If the deviation between the actual RTD temperature and the temperature of the standard is greate~ than plus 1.0 degrees Fahrenheit, the entire calibration curve for the RTD is shifted to correspond to the temperature of the standard.
Containment dewpoint temperature was monitored by five 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 analyzPrs 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 the condensation is detected, cooling is controlled to held 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 Type A test by the vendor and their accuracy was certified as being traceable to NBS.
An additional one point check was performed for each analyzer using station procedure Ol-PT-16.3D.
6.2
6.1 EQUIPMENT USED (CONT'D)
Containment pressure was monitored by the use of two Mensor Ouartz manometers.
These manometers use the Containment Leakage Monitoring (LM) system through Leakage Monitoring Connections on the 13 1 level of the Auxiliary Building.
The signal from these manometers was fed into the P250 computers.
The manometers were calibrated within six mor.ths of the Type A test by the original manufacturer with the accuracy being certified as being traceable to NBS.
A Hastings linear mass flowmeter was used to monitor flow for the superimposed verification test which proceeded the 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 1 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 NBS by the original manufacturer within six months of the Type A test..1 lists pertinent information for the instrumentation that was used during the Type A test.
6.3
6.2 CILRT PROGRAM -P250 COMPUTER The ILRT program on the P250 computer gathers and logs the required data during the Type A test.
The data is printed out in log format which is then input into the ILRT analysis program on the IBM-PC.
The ILRT program on the P250 computer consists of three sub-programs.
These programs are run on both units P250 computers during the Type A test.
The program on Unit Two's computer would be used as a backup if Unit One's computer fails.
The three programs are MANOS, ILRTDATI and ILRTPRTI.
The MANOS program is used to convert the BCD output of the quartz manometers into floating point numbers.
MANOS 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 ILRTDATI program used the 22 containment RTD readings, 5 moisture analyzer readings and 2 pressure readings to apply the appropriate weighting 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 sensors by summing the instantaneous readings taken during a ten minute period and dividing the totals by the number of readings taken.
The RTDs and moisture analyzers are scanned every 20 seconds by the A&I program.
The ILRTDATl program also performs sensor checks by checking the difference between the ten minute averages of sensors within the same zone against a 6.4
maximum limit.
When the maximum limit is exceeded, the program notifies the operator vi a an error message printed out on the a 1 arm t,ypewri ter 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 sensor weight factor to the remaining sensors in its zone.
The ILRTPRTl program generates a formattP.d loQ of the ILRT data that is gathered by the ILRTDATl program.
The program is bid every ten minutes by the ILRTDATl program or manually via the operators console.
Also the plant process computer P-250 ILRT program was modified to print out the instantaneous data used in the ten minute average calculations and also to perform weighted average temperature and mass calculations on the instantaneous data
- 6.5
6.3 CILRT PROGRAM - PC COMPUTER The Type A test program on the PC computer is used to calculate and plot the change in mass of containment versus time~
Input data for the program is obtained from the plant process computer (PZ50) data collection program.
The variables which are manually input into the PC program are time, containment pressure, dewpoint temperature and containment temperature.
The variables are stored in a data file when input into the program.
The user then has the option of performing various subroutines which enable the user to caclulate 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.
In the calculation mode, the user has the option of performing either mass point; total time or point-to-point analysis.
Mass point was the only method used for this test since Amendment No. 120 was issued by the NRC on May 24, 1988.
This Amendment modifies Section 4.4, "Containment Test 11 of the Surry Units 1 & 2 Technical Specifications to reflect the use of the Mass Point method for calculating containment leakage rates, which is described in ANSI/ANS 56.8-1987, "Containment System Leakage Testing Requirements."
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 P-250 computers.
Air mass is calculated using the ideal gas law formula.
The formula is as follows:
6.6
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 0 P. (for air)
T=average containment temperature, deg R V=containment free volume, 1.8xE6 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:
Where:
M=At+B 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 <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> out of containment:
Leakage Rate:
= (dM/dT)/Mo x (-2400)
The sign convention is such that a positive leakage rate value is an
\\
indication of outward leakage.
The units for this value are in wt%/day.
6.7
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.

8.0 LOCAL LEAK RATE TESTS Type Band C tests were performed on containment penetrations prior to the Type A test. The As-Found and As-Left test results for these penetrations are shown in Attachment 8.1.
The attachment also gives a description of any repairs if they were performed.
Also included in that attachment are Type B and C test results for tests that were performed since the last CILRT in July 1986.
The total As-Found Type Band C leakage value during the 1988 Refueling Outage was 177.372 SCFH when applying minimum pathway criteria. This value is below the maximum leakage of.6La (180 SCFH) as specified in 10CFR50, Appendix J, Section III.B.3(a).
The total-As-Found Type Band C leakage value, when not using minimum pathway criteria, was 793.764 SCFH.
This value is above the maximum leakage of
.6La (180 SCFH).
The corrective action taken to reduce the Type Band C leakage below.6La was to repair/replace valves which had leakages above the maximum allowable leakages as specified in the Type C test procedure.
Following these repairs, the final As-Left Type Band C leakage value was 39.3915 SCFH which is well below the.6La value of 180 SCFH.

9.0 AS-FOUND TYPE A TEST ANALYSIS An As-Found analysis has been performed on the Type A test to determine the leakage savings.
The purpose is to determine what the actual Type A test leakage rate would be if the Type A test had been performed at the beginning of the outage prior to Type Band C testing.
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)
Minimum pathway leakage is the lowest leakage of the inside or outside valve grouping for the penetration in question.
- 3)
If there were no repairs or replacements, a zero leakage savings is assessed to the penetration.
- 4)
If the post-repair minimum leakage is greater than pre-repair minimum pathway leakage, a leakage savings of zero is assigned to the penetration.
- 5)
The leakage savings is the difference between the pre-repair minimum pathway and'post-repair minimum pathway leakages.
- 6)
The *net leakage savings (wt% day) is added to the final Type A test results
- 9.1
9.0 AS-FOUND TYPE A TEST ANALYSIS (CONT'D}
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 a subatmospheric pressure.
The penetrations identified by note 1 through 4 in.A.ttachment 9.1 are excluded as credible leakage sources.
The analysis and technical justification for excluding these specific penetrations was submitted to the NRC in correspondence dated November 16, 1987, August 5, 1988, and August 15, 1988.
(Serial Nos. 87-707A,B,&C)
RESULTS As noted in Attachment 9.1, the as-found integrated leakrate was 0.5055 wt%/day which is less than the acceptance criteria of 10CFR50 Appendix J (0.75 wt%/day).

SUMMARY
NOTES:
- 1) This line is from the charging pump header and is used to' supply the loops.
The charging pumps are used as the high head safety injection pumps and this line (penetration) remains pressurized during post accident conditions.
The eves system valves, piping and components have been designed to permit essentially zero leakage.
Periodic surveillance is performed to verify that leakage is within specifications. Reference Surry UFSAR Section 6.2.3.10, External Recirculation Loop Leakage.

This line is from the low head safety injectjon pump header and is used to supply the loops and this lin~ (penetration) remains pressurized during post-accident conditions.
The safety injection system valves, piping and components have been designed to permit essentially zero leakage.
Periodic surveillance is performed to verify that leakage is within specificatfon. Reference Surry UFSAR Section 6.2.3.10, External Recirculation Loop Leakage.
- 3) The recirculation spray system is designed to operate after the OBA LOeA to depressurize the containment to subatmosphetic pressure.
The sump lines are filled with water and would prevent atmospheric out leakage either through operation and/or static head.
