1.0 INTRODUCTION
A successful 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> preoperational Integrated Leakage Rate Test (ILRT) was ;
conducted on the South Texas Project Electric Generating Station (STPEGS)
Unit 1 containment building on March 24 and 25, 1987. This test was per-formed to demonstrate that the containment leakage under prescribed post accident conditions does not exceed the allowable leakage rate value spe-cified in the STPEGS Unit 1 Technical Specifications. The ILRT was fol-lowed by a successful verification test to verify instrumentation perfor-mance.
These tests were conducted in accordance with the STPEGS preoperational test procedure (1-RC-P-03), to comply with the requirements of the STPEGS FSAR and Technical Specifications and Appendix J to 10CFR50. The leakage rates were calculated using formulas identified in ANSI 45.5-1972 " Leakage Rate Testing of Containment Structures for Nuclear Reactors" ANSI /ANS 56.8-1981 " Containment System Leakage Testing Requirements", and BN-TOP-1, Rev. 1 " Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants".
A summary of the test events and test chronology are presented in Section 2.0, Test Synopsis. Plant information, technical data, test results, and measurement system information are presented in Section 3.0, Test Data Summary. Test results are compared to the Acceptance Criteria in Section 4.0, Analysis and Interpretation. Referenced documents are listed in Sec-tion 5.0, References.
2.0 TEST SYNOPSIS The containment was isolated by aligning systems in the specified post accident modes, except as noted in Section 4.1. Prior to pressurization, the containment sump water levels were measured to verify a nominal water level. A pre-test walkdown of the containment structure yielded no unac-ceptable structural deterioration. The ILRT was conducted after the Structural Integrity Test (SIT). Containment pressurization for the SIT started at 2320 on March 21, 1987 (SIT Report under seperate cover). ILRT pressure (52.2 psia) was reached at 1400 on March 24, 1987. The pressur-ization lines were isolated from containment and vented.
The temperature stabilization criteria was satisfied during the period of 1430 to 1915 on March 24, 1987.
The ILRT test period began at 1930 on March 24. Initial test pressure was 52.080 psia. Containment pressure and temperature were recorded at 15 minute intervals using electronic sensors and data logging devices. Con-tainment vessel water levels and barometric pressure were monitored at one hour intervals. The Type A test was terminated at 1930 on March 25, 1987,
'after twenty four hours of data had satisfied all leakage rate acceptance criteria. The test data resulted in a calculated leakage rate of 0.0314 wt %/ day using the Mass Point calculation technique and 0.0245 wt %/ day using the Total Time calculation. The 95% upper confi-dence limits were 0.0320 wt %/ day and 0.0321 wt %/ day for the above tech-niques respectively. These leakage rates, which include a correction of 0.0036 wt %/ day for those penetrations which were not in a post-accident lineup, satisfy the acceptance criteria of 0.75La, or 0.225 wt %/ day.
The verification test was initiated by continuously venting approximately 26.3 SCFM of air from the containment through a mass flow transducer. The verification leakage rate calculated using the 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of data from 2045, March 25 to 0045, March 26, 1987, verified the performance of the instru-ment system. This leakage rate was calculated to be 0.3188 wt %/ day using the Mass Point technique and 0.3260 wt %/ day using the Total Time tech-nique. These results satisfy the acceptance criteria of being within the range'of 0.2528 to 0.4028 wt %/ day for Mass Point and 0.2459 to 0.3959 wt %/ day for Total Time.

4.0 ANALYSIS AND INTERPRETATION 4.1 Integrated Leakage Rate Test During the ILRT, a total of fourteen penetrations were not in post-accident alignment. Eleven of these are described in STPEGS FSAR Table 6.2.6-1
" Systems not Vented During Type A Testing". Two others were in use during the ILRT and Verification Test. The final penetration was identified dur-ing pressurization as having an inadequate lineup, in that it was not vented inside containment. The minimum path leakage rate test values for these penetrations are given in section 3.3.11 of this report. Also iden-tified prior to pressurization were four of the 177 liner weld leak chase channels which could not be vented because the vents were inaccessible.
Records from previous individual tests on these leak chase channels indi-cate no leakage so no correction is necessary.
The calculated leakage rates during the ILRT for least square fit (LSF) and 95% upper confidence limit (UCL) are shown below. Adding the total leakage rate corrections for penetrations not in post-accident alignment is included.

Rate O.0036 0.0036 0.0036 0.0036 Correction Total Leakage ,0.0314 0.0320 0.0245 0.0321 Rate Since the corrected 95% UCL for mass point and totai time are less than 0.75 La (0.225 wt %/ day) the test results demonstrate the leakage through the primary containment and systems is within allowable limits as identi-fied in STPEGS Unit 1 Technical Specifications.
4.2 Instrumentation, Data and Calculations ILRT test' data was gathered through sensors and a data acquisition system.
The data acquisition system received inputs from the sensors and trans-mitted them into a personal computer which reduced the raw data to a calcu-lated leakage rate (See Appendix A for a software description).
4.2.1 Instrumentation The instrumentation was chosen for its stability and dependability.
The instrumentation used during the ILRT satisfied all Instrumenta-tion Selection Guide requirements. All instrumentation performed adequately during the test.

\?
4.2.2 Sensor Location and Volume Fractions A mathematical model of the containment was developed using eleva-tion and plan view drawings to define containment-subvolume boun-daries. Subsequent to subvolume boundary definition,' volume frac-tions were assigned to each subvolume in the containment. Sensors were then placed as near to.the centroid of each subvolume as pos-sible to detect' changes in containment atmospheric conditions.
Tabla 1 indicates sensor locations relative to volume fraction assignments. A pre-test temperature survey was performed to verify that the instrument locations accurately represented their subvo-lumes.
Sensor placement provided a stable accurate representation of con-tainment. atmospheric conditions during the ILRT. All sensors oper .
'ated without the disturbance of containment ventilation or. chiller operation. yielding highly reliable test data.

SUMMARY
1.0 Introduction The Type A test is an integrated leakage rate test (ILRT) designed to ver-ify the leak tight integrity of the entire containment building. The ILRT is performed in accordance with ANSI /ANS 56.8-1981 " Containment Systems Leakage Testing Requirements", ANSI N45.4-1972 " Leakage Rate Testing of Containment Structures for Nuclear Reactors", and Bechtel Topical Report BN-TOP-1 " Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants".
The STPEGS ILRT computer program computes total time leakage rates, mass point. leakage rates, LSF leakage rates, and 95% upper confidence limit (UCL) leakage rates during the course of an ILRT from input measured values of containment pressure, temperature, and dew point temperature. The com-puter program is also capable of performing verification test calculations and will. generate specific features,to aid in verifying the ILRT.
The computer program is designed to automate the task of sampling and reducing the data to a usable form in accordance with the documents men-tioned above. This greatly limits the possibility of. human error and pro-vides intermediate results after only a short delay. This makes it pos-sible to monitor =the progress of the test very closely in approximately real time.- For each of the two test periods, the computer program samples the containment's environment and calculates the values needed to assess the status of the test. Interim results are provided as desired and the program checks to see if the acceptance criteria have been satisfied for the two test periods. The software also produces a printout of all data gathered as well as a record of its calculations. In addition, the data is stored on hard or floppy computer disks for future reference. The program can recover from a power failure or any other accidental interruption of the program's execution by reloading the old data and restarting the data sampling routine at the proper location. Lastly, should one of the instru-ments fail during the test, the program will detect the problem and the user can remove that sensor from further calculations. When the test is completed, the program has the ability to recalculate all values for the test, suppressing any failed instruments from the entire series of calcula-tions.
The STPEGS ILRT computer program is written in a high level language (BASIC) and is designed for use on a micro-computer with direct data input from the data acquisition system. Brief descriptions of program use, ori-gin of formulae used for leakage rate computations, and program logic are provided in the following sections.
2.0 Explanation of Program The STPEGS ILRT computer program is written for use by ILRT personnel to determine containment integrated leakage rates based on the Absolute Method described in ANSI /ANS 56.8-1981, ANSI N45.4-1972, and BN-TOP-1.

Information loaded into the program prior to or at the start of the test:
- a. Number of containment atmosphere drybulb temperature sensors, dew point temperature sensors, and pressure instruments to be used in leakage rate computations for the specific test.
- b. Volume fractions assigned to each of the sensors.
- c. Calibration data for sensors.
- d. Test title.
- e. Test pressure.
- f. Maximum allowable leakage rate at test pressure.
Data recorded from the data acquisition system during the test, and used to compute leakage rates:
- a. Time and date.
- b. Containment atmosphere drybulb temperatures.
- c. Containment atmosphere pressures.
- d. Containment atmosphere dew point temperatures.
If the drybulb or dew point temperature sensors should fail during the test, the data from the sensor (s) is not used. The volume fractions for the remaining sensors are revised and reloaded into the program for use in ensuing leakage rate calculations.
3.0 Program Logic and Operation Summary Initial startup of the STPEGS ILRT computer program requires that some executive questions be answered as shown in Figure A.I. The computer pro-gram logic flow is then controlled by a set of user options. Figure A.2 outlines the basic logic for running the program options. These options and a brief description of their associated functions are presented below:
LOG ON Allows for use of the data acquisition system for automatic data recording or suspends data acquisi-tion use.

UPDATE If the records are changed or deleted, this option redefines the entire file so that the calculations can be made without interfering with the computer's file handling capabilities.
REPORTS This function performs the calculations of the pro-gram and prints the results.
PLOTS This function implements the graphics portion of the program. Any channel or leakage rate can be plotted.
END This option properly terminates the program.
4.0 Computer Reports and Plots 4.1 REPORTS REPORTS does the analysis of the data accumulated by the ILRT system and then prints out a report of the results. The types of analysis performed are: mass point, total time, environmental averages, mass loss, tempera-ture stabilization, and data rejection. All results from the analysis are printed. The subprogram REPORTS requires the user to select a valid time window or record window as listed below as a prerequisite for performing the analysis.
MASS POINT The mass point report, based on the ANSI /ANS 56.8-1981 standard, identifies leakage rates and the associated 95% upper confidence limits and compares them to the acceptance criteria.
TOTAL TIME The total time analysis, based on the Bechtel Topi-cal Report (BN-TOP-1), identifies the mer.sured and calculated leakage rates and the associated 95%
upper confidence limits and compares them to the acceptance criteria.
ENVIRONMENT The environment report lists relevent containment parameters as recorded by the instrumentation system and calculated by the computer program.
MASS LOSS The mass loss report provided projected mass loss rates for evaluation.
TEMP STAB The temperature stabilization report is based on temperature stabilization criteria given in BN-TOP-1 and ANSI /ANS 56.8-1981.
A-4
DATA REJECT The data rejection report is based on data rejection criteria given in ANSI /ANS 56.8-1981.
4.2 PLOTS The graphics subprogram PLOTS allows the user to plot the mass point analy-sis, total time analysis, and displayed channels. Further, plots can be made in a batch mode by instrument type to a plotter. PLOTS performs auto-ranging of the data being plotted for axes values. PLOTS requires the user to select any valid time window or record window as a prerequisite for plot generation.
