1.0 INTRODUCTION

L The Second Periodic Integrated Leakage Rate Test (ILRT) at Georgia Power Company's Vogtle Electric Generating Plant (VEGP) Unit 2 was performed on March 4-5,1995. The ILRT was performed as required by 10CFR50 Appendix J (reference 1) and the VEGP Unit 1 and Unit 2 Final Safety Analysis Report (FSAR)(reference 4) to demonstrate that leakage through the containment boundary at design basis accident pressure does not exceed the VEGP Technical Specification (reference 2) limit. The test was performed in accordance with Procedure VEGP 28329-2 Revision 9 (reference 3). The following documentation is retained at the site along with the Official Test Copy of the procedure:

SUMMARY

l 0, The Second Periodic Integrated Leakage Rate Test for the VEGP Unit 2 containment was  ;

successfully completed at 7:30 a.m. on March 5,1995. The duration of the test was 8 l hours. The results of the test follow: (Additional leakage to account for penetrations in service or isolated during the test and not in post accident alignment is included in the leakage rates. The 95-percent upper confidence level (UCL) plus any penalty addition is referred to as the final leakage rate.) l Leakage Rate  !

(weight % per day)

TotalTime Analysis Determined Value Acceptance Limit 95% Upper Confidence Limit 0.0938 0.1500 O

Extrapolated Leakage Rate < 0.0500 0.1500 Mean of Measured Leakage Rates 0.0574 0.2000 t

Leakage penalties are added to the above 95-percent UCL total time leakage rate to account for penetrations in nonstandard alignment and for water inventory change. Total penalties amounted to a leakage of 0.0001 weight percent / day. This results in a final a:,-

left leakage rate of 0.0939 weight percent / day, which is less than the acceptance limit of 0.1500 weight percent / day.

To determine the as-found leakage rate, minimum pathway improvements made during the local leakage rate testing program previous to the Type A test are added to the sum of the 0.0938 weight percent / day UCL and the 0.0001 weight percent / day penalties. Since the minimum pathway improvements amounted to zero, the final as-found leakage rate is 0.0939 weight percent / day which is less than the acceptance limit of 0.2000 weight .

percent / day.

3.0 METHODOLOGY 3.1 Leakage Rate Calculations Test methods and procedures are specified in ANSI N45.4-1972 (reference 6) and in Bechtel Topical Report BN-TOP-1 (reference 7). ANSI N45.4 and BN-TOP-1 are cited in the VEGP FSAR. ANSI N45.4 is cited in 10CFR50 Appendix J. BN-TOP-1 is an alternative method acceptable to the USNRC.

Reference 7 describes the total time test which is used for Type A tests of a duration less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Since the Type A test described in this report was less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, the total time calculations as described in reference 7 were used to determine leakage rate.

Reference 1 allows leakage rate calculations to be performed using the mass point method defined in ANSI /ANS 56.8 (reference 5). The Type A test must have a duration of at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to use this methodology per reference 1. Mass point results are provided in this report for information only.

Data from the instrumented containment is reduced by direct application of the ideal gas law, PV = w RT, to calculate air mass at each data point. The change in air mass provides information to develop the leakage rate.

The total time data analysis technique is based on the premise that the leakage rate varies with time. A measured leakage rate is calculated as the initial air mass minus current air

("f mass divided by current time minus initial time. A straight line is then fitted to the measured rate versus time data. The calculated leakage rate is defined as the ordinate of this line at the end of the test.

The total time test has three acceptance criteria. First, the end-of-test leakage rate 95-percent UCL must be less than the acceptance leakage ra:e (0.75 La). Second, the calculated leakage rate extrapolated to a 24-hour test duration must be less than the acceptance leakage rate (0.75 La). Third, the mean of the measured leakage rates over the final 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of the test must be less than the maximum allowable leakage rate (La).

3.2 Test Measurements Thirty dry-bulb and six dew point temperature sensors located inside containment at approximately equally spaced elevations were used to collect information for leakage rate calculations. Sensor locations and volume fractions (table 1) were established by considering temperature distributions in past tests, previous temperature surveys, and the containment free volume.

Since both dry-bulb and dew point temperatures tend to exhibit a vertical stratification at the completion of pressurization and throughout the test, sensors were set at approximately aque!!y spaced elevations. The volume associated with each sensor was taken as a pb horizontal slice through the containment with the sensor at its approximate vertical 3

p) i vertical centroid. Sensor support points were created by ropes hung from spray rings, the polar crane, and structural steel. The bearing of each sensor was advanced to the next support point from that of the sensor above it, creating a downward spiral. Above the refueling floor, the radius was set such that one-half of the horizontal area was inside the spiral surface and the other half outside. Below the refueling floor, sensors were positioned about midway between the secondary shield wall and the containment liner.

One dry-bulb sensor was suspended in the refueling cavity. Sensors above the refueling floor were suspended from spray rings, the polar crane, and structural steel. Those below the refueling floor were suspended from grating, piping and structural steel.

Dry-bulb temperatures were measured using 100-Ohm platinum resistance temperature detectors (RTDs). Dew point temperatures were measured using optical chilled mirror dew point hygrometers. These dew point devices use a direct-measuring sensor automatically held at the dew point temperature by an optical system. This technique is a primary measurement of the water vapor content of the air. The mirror temperature represents the true dew point temperature and is measured by an imbedded precision platinum resistance thermometer.

Absolute pressure was measured using a vibrating cylinder element sensor connected through tubing to a modified electrical penetration. The change in pressure during an ILRT is quite small relative to absolute pressure. The pressure device used has an accuracy of +/- 0.015 percent RDG, +/- 0.002 percent F.S. and a repeatability of +/- 0.001 percent F.S.

A data logger was used to collect data at 15-miaute intervals. Information from the RTDs, dew point sensors, and pressure indicators was transferred from the data logger to the ILRT computer for analysis. The data system generated a printed tape and floppy disk record of each data set transmitted to the computer.

The computer used for the ILRT was an IBM compatible. A compiled Basic program as described in appendix I was run on the computer.

The imposed leakage rate for the verification test was measured using a float type flowmeter.

All instrumentation was calibrated within 6 months of the ILRT. Instrumentation characteristics and calibration information are summarized in appendix III. Calibration documents are included with the site procedure.

4.0 TEST PROCEDURE (q) 4.1 Initial Conditions A general inspection of the accessible interior and exterior surfaces of the containment building was performed prior to the ILRT. No repairs or adjustments were made to the containment after initiation of the inspection so that the building could be tested as close as practical to the "as is" condition. The inspection uncovered no evidence of structural deterioration which would affect the containment structural integrity or leak-tightness.

Since the Type A test was performed at the beginning of the outage, the Type B and C local leakage rate testing (LLRT) was only partially completed prior to the inspection. All Type B and C as-found tests were completed before the ILRT.

Plant systems were aligned for the ILRT as specified in the plant procedure. Isolation valves, except those in systems required to maintain the plant in a safe condition and those systems used to conduct the ILRT, were set in post-LOCA positions specified in the FSAR. Any penetrations deviating from the FSAR positions are listed and justified in the

! ILRT procedure.

For those systems or penetrations that were in service or isolated during the test, a penalty addition must be made to the Type A test results. The penalty addition is the sum of the minimum pathway leakages for those penetrations determined to be in a position other than normal post-LOCA position. Penetrations included in this penalty calculation were

\, ILRT Pressurization (#68), ILRT Pressurization (#87), ILRT Sensing (#31), and Containment Sump Discharge (#78).

Piping was vented and drained to expose valve seats per post-LOCA scenarios. All sources of gas at pressures above containment test pressure were isolated or vented to prevent leakage into the containment during the ILRT.

An in-situ test on the sensors was performed to demonstrate the proper functioning of the sensors and the data collection system. RTD in-situ tests were done using an ice bath (32 degrees F) and verifying that temperature at the data system. Dew point in-situ tests were done using a calibrated dew point instrument (spare dew cell) or a calibrated sling psychrometer to measure dew point temperature at each sensor and comparing the results with dew point temperature at the data system. The in-situ checks that all RTDs were operating within +/- 1 degree of the standard and all dew cells were operating within +/- 5 degrees of the standard.

The site procedure documents the completion of the prerequisites for the test, including all exceptions to specified conditions.

4.2 Pressurization The containment was pressurized using oil free compressors discharging through an after j cooler / moisture separator and refrigerated air dryer. A total compressor capacity of 5

l I

fm ~

approximately 18,000 SCFM was used. Compressor discharge to containment was routed through temporary piping to' containment penetrations 68 and 87. Start of pressurization occurred at 8:35 a.m. on March 4,1995. Pressurization was terminated when containment pressure reached 37.8 psig at 5:00 p.m. on March 4,1995. This allowed a 0.8-psi margin for pressure drop to ensure the gage pressure would be at or above the 37-psig minimum pressure required for the test.

Containment lights were turned off and temporary power to containment was isolated for f the test. In addition, permanent plant instmmentation that was not qualified to 37 psig I was removed from containment.

l 4.3 Stabilization Upon reaching ILRT test pressure, the containment was allowed to stabilize. An initial drop in pressure was observed and then stabilized at approximately 37.4 psig. The i

stabilization period was not started until 6:45 p.m. on March 4 in order to verify the i containment pressure was going to stabilize above 37 psig. Data was recorded at 15-minute intervals. The last stabilization data point was taken at 11:30 p.m. on March 4, 1995. All stabilization criteria were met for this point (table 2). Actual change rates and maximum allowable change rates are listed below:

4.4 Type A Test The Type A test was started at 11:30 p.m. on March 4. Containment conditions were O recorded at 15-minute intervals. The test was successfully concluded at 7:30 a.m. on 6

March 5. Results of the test are recorded in section 5.1 of this report. The Type A test was conducted in accordance with the provisions of BN-TOP-1 (reference 7).

During the acquisition of Type A test data, a momentary loss of signal was experienced for dew cell #1 at the 12:45 a.m. data point. The data acquisition paper tape recorded a negative value indicating a loss of signal. A visual reading of the LED display for this sensor immediately after 12:45 indicated a correct reading of 45.12 degrees. The data points before and after this data point both recorded correct values. No further incorrect values were recorded. Based on the negative value (the 12:45 a.m. data point for dew cell

1. 1) being attributed to a momentary loss of signal, the visually observed value was manually inserted for the data point in question.

To further demonstrate the validity of this approach, another method of disposition of this data would be to reject the data point. (The data point with the negative temperature value meets data rejection criteria). By removing the data set, the net effect on the final leakage rate would be 0.0005 weight percent / day; i.e., no effect.

Thus, it is concluded that insertion of the visually recorded value is reasonab!c. The details of the action are recorded in the test log.

4.5 Verification Following completion of the Type A test, a 13.04 SCFM (0.1966 weight percent / day)

( verification leak was imposed, which is between the limits of 0.75 La and 1.25 La specified in reference 7. Containment atmospheric conditions were allowed to stabilize for I hour. The verification test was then started at 8:45 a.m. on March 5 and successfully completed at 12:45 p.m. on March 5. Results of the test are recorded in section 5.2.

Table 3 provides a summary of data collected during the stabilization, the Type A test, and the verification as discussed in sections 4.3,4.4, and 4.5.

4.6 Depressurization Containment depressurization was started at 1:00 p.m. on March 5 at an average rate of no more than 10-psi per hour. Depressurization was completed at 6:50 p.m. on March 5.

Containment and other plant systems modified for the ILRT were restored following depressurization to support the outage schedule.

l 5.0 RESULTS AND ANALYSIS 5.1 Total Time Results  :

The end of test leakage rate was well within the acceptance criteria stated in references 2 and 3. This includes the 95-percent UCL plus any penalty additions. Penalty additions are the sum of the minimum pathway leakages determined for those penetrations which were not in a normal post-LOCA position. A summary of these penetrations and their contribution to the penalty addition is presented below:

Penalty Additions Penetration Description As-left leakage (SCCM 31 ILRT Sensing 0.0 68 ILRT Pressurization 6.0 78 Containment Sump Discharge 180.6 87 ILRT Pressurization 6.0 Total Leakage (SCCM) 192.6 Total Leakage 0.0001 (wt %/ day)

Other test result adjustments consider water inventory corrections. The overall water inventory correction review yielded a slight reduction in leakage rate and thus, being  ;

conservative, no adjustment was made. Details of the documentation are included in the l plant procedure.

The VEGP Technical Specifications specify a maximum allowable leakage rate of 0.2000 weight percent / day. To allow a margin for deterioration of the leakage boundary the as- l lefl leakage rate must be less than 75-percent of the maximum allowable rate (0.1500 weight percent / day). UCL leakage rate, penalty addition, final as left leakage rate and acceptance limit are listed below:

f The as-found leakage rate is calculated by adding the 95-percent UCL, the penalties for non-standard alignment, the adjustments for water level inventory, and the penetration minimum pathway improvements made during the local leakage rate testing program previous to the Type A test. As stared above, no correction was included for the water inventory adjustment since it yielded a slight reduction in the leakage rate. The minimum pathway improvement was zero. Thus the as-found leakage rate is as follows:

The air mass plot (figure 2) shows lines whose slopes represent leakage rates. A least squares fit line is plotted through the actual test data which must lie above a line representing the acceptance limit. As seen in the graph, the actual leakage rate was easily less than the allowable rate. The temperature plot (figm 3 3) shows the weighted average dry-bulb temperature of the containment air mass. The atal temperature change was 0.9305 degrees F over the 8-hour test period. The pressui plot (figure 4) shows the containment total pressure and a total change of 0.0952 psi. The vapor pressure plot l (figure 5) shows a change in vapor pressure of 0.0032 psi. Figure 6 shows a plot of total time leakage rate data from table 4. The leakage rate UCL must be below a line representing the acceptance limit. As seen from the graph the UCL is well below the allowable limit.

5.2 Verification Results The verification test introduced an additional leak of 13.04 SCFM (0.1966 weight percent

/ day). Verification test results are listed in table 5 and graphed in figures 7 and 8. The results of the verification test are acceptable if the leakage rate calculated after imposition 10 r4 -

-p of the additional leak falls within the limits of(Lam + Ln) +/- 0.25 La, where Lam is the

( previously calculated leakage rate (0.0497), Lo is the imposed leakage (0.1966), and La is the maximum allowable leakage rate (0.2000). The final results and acceptance limits are listed below:

APPENDIX I O ILRT COMPUTER PROGRAM DESCRIPTION The ILRT computer program used in this test was a program purchased by Southem Company Services (SCS) from BCP Technical Services. The program is a modified version of the BCP standard ILRT program prepared for specific use at VEGP. Complete verification of the VEGP version has been performed and documented. The program source code was included in the purchase of the software should there be the need to review the routines used to calculate the various ILRT parameters. The BCP ILRT program is written in Microsoft QuickBASIC, Version 4.5, for IBM Personal Computers and Compatibles.

Upon starting the program the user is prompted for the fbliowing predata:

Number of temperature sensors Number of dewpoint sensors Number of pressure sensors Containment free air volume Allowable leakage rate, La Sensor volume fractions Once the test is started the following data is received from'the data acquisition system during the test:

Time and date Containment atmosphere drybulb temperatures Containment atmosphere pressure Containment atmosphere dewpoint temperatures Program options provide calculation of the following reports:

v TYPE B AND C RESULTS NOTES Sheet 10 of 10 NOTEI Penetration 11 A: Check valve 2-1411-U4-031 would not seat initially. While the technician was verifying the leakage was past the check valve, the check valve seated. Reference Deficiency Card 2-93-096. Note that the "As Found" leakage on the outboard valve was within limits (42.6 sccm). In addition, the outboard valve is administratively held closed while in Modes 1-4 (the fuses to the solenoid that operates this fail-closed AOV are removed prior to Mode 4 entry.

NOTE 2 Penetrations 11 A,12A,69A, and 69B: "As Found" LLRT's for 2R3 were performed on check valves 2-1411-U4-029,-031,-043, and -044. These valves were replaced with manual globe valves under Design Change Package 92-V2N0135 during 2R3. He "As Len" leakage values for 2R3 and subsequent 2R4 leakage values are for the new globe valves. The check valves were replaced due to their history of LLRT failures.

NOTE 3 Penetration 15: De bonnet bolts were tightened on 2-1213-U6-051 prior to performing an "As Found" LLRT. The valve was reported as having water spraying at the valve body and the bonnet bolts were tightened immediately prior to performing the LLRT. The LLRT was being performed

to determine the operability of the two containment isolation valves. De LLRT was acceptable on both 2-1213-U6-050 and 2-1213-U6-051.

l Reference Deficiency Card 2-92-259.

l NOTE 4 Electrical Penetration 17: Nitrogt pressure for electrical penetration 2-1818-il3-Pl7 was found at 12 psig. Reference MWO 29203468.

NOTE 5 Penetrations 36,37,38, and 39: Two encapsulation vessels were found to have loose nuts. Reference Deficiency Card (DC) 2-93-027. Those two vessels were retoiqued, while the other two had their torques verified.

l NOTE 6 Penetrations 36,37,38, and 39: Leak Rate Tests performed to check for relaxation of gasket clamping force. Tests were a corrective action based on DC 2-93-027 described in Note 5 above.

NOTE 7 Penetrations 36,37,38, and 39: "As Found" and "As Len" LLRT's performed due to performance of Design Change Package 93-V2N0080 for the installation ofinspection ports on the encapsulation vessel heads to allow visually observation of valve stroke without requiring removal of vessel head. Only one vessel lid was removed at a time, and each modified vessel was LLRT'd prior to the removal of the next vessel lid.
