1.0 INTRODUCTION

Successful-preoperational Integrated Leakage Rate (ILRT) and Drywell Bypass Leakage Rate (Bypass) Tests were conducted on the Clinton Power Station Unit I reactor containment building between November 3, 1986 and November 4, 1986. These tests were performed to demonstrate that the containment leakage and drywell bypass leakage rates do not exceed the allowable values specified in the Clinton Power Station Unit 1 FSAR (Reference 1) and Clinton Power Station Technical Specification (Reference 2).

The ILRT and Bypass tests were conducted in accordance with the requirements of the ILRT procedure (Reference 3), Appendix J to 10CFR50 (Reference 4), ANSI'56.8 (Reference 5), BN-TOP-1 (Reference 6), and ANSI 45.4 (Reference 7) . Test pressure for the ILRT and Bypass tests were 9 psig and 3 psig respectively. Test results, which satisfied all acceptance criteria, are summarized below.

2.0 TEST SYNOPSIS Prior to performing the leakage rate tests, all pressure, temperature humidity, and flow sensors were calibrated and the temperature and humidity sensors installed in the drywell and containment at the locations tabulated in Table 1. An in-situ check was performed on all sensors per the requirements of ANSI /ANS 56.8 - 1981. Per the requirements of the 10CFR50 Appendix J, the containment was isolated by aligning systems in specified post-accident mode, with the exceptions listed in Section 3.C.12. On October 23, 24, 1986 a pre-ILRT Containment and Drywell structural inspection was conducted resulting in discovery of nine temporary attachments requiring removal prior to commencing the test. All attachments were removed by November 1, 1986. No other discrepancies that would impact the test were noted.

Pressurization for the Containment ILRT began at 0957 on November 3, 1986. ILRT test pressure of 9 psig was reached at 1430 on November 3, 1986. Temperature stabilization commenced at 1430 November 3, 1986 and was completed 4.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months later. The BN-TOP-1 stabilization criteria of less than l'F/hr over the last 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months was met in 2) hours. The ANSI 56.8 stabilization criteria that the last hour weighted average does not deviate by more than 0.5'F from the weighted average rate of change over the last 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months was met in 4.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months . Temperature stabilization data is presented in Appendix B. Subsequent to the temperature stabilization period, a 9.00 hour0 days 0 hours 0 weeks 0 months ILRT was conducted from 1900 on November 3, 1986 to 0400 on November 4, 1986. The mass point calculated leakage rate was 0.260 %/ day with an upper confidence limit of 0.266 %/ day. The total time calculated leakage rate was 0.262 %/ day with an upper confidence limit of 0.293 %/ day. Both upper confidence limits were less than the allowable leakage rate of 0.4875 %/ day (75% of La). The total time calculations satisfied all short duration test requirements of BN-TOP-1 and the mass point calculations satisfied all short duration test requirements of ANSI /ANS 56.8-1981.

The verification test was initiated at 0515 on November 4 by continuously venting 13.04 scfm (100% of La) of air from the containment through a flowmeter and allowing test conditions to stabilize for one hour. A 41-hour verification test was conducted from 0515 to 0945 on November 4. The mass point calculated and total time calculated verification leakage rates of 0.845

%/ day and 0.854 %/ day, respectively, were within the required ranges of 0.740 to 1.066 and 0.742 to 1.067 %/ day respectively to verify the performance of '

, the ILRT instrumentation.

Following the verification test the drywell was depressurized to 3 psig l and the containment to 0 psig. The Drywell Bypass Leakage Rate Test was l performed between 1931 on November 3 and 2341 on November 3 at a test t pressure of 3 psig. A drywell bypass leakage rate of 20.77 scfm was l calculated as the leakage rate obtained during the pressure decay test.

The calculated leakage satisfied the acceptance criteria of being less than 4,312 scfm. The data and pressure decay leakage rate calculations are presented in Appendix I. Following the leakage rate test, the drywell was depressurized.

Prior _to'the atart of pressurization it was elected to use the more.

conservative 5% data rejection criteria per ANSI 56.8. During the ILRT on November 4, at 03,15 humidity sensor No. 3 exhibited an excursion to 75.53% RH and the data set'was rejected, as it met both 1% and 5% criteria. The sensor was continuously monitored and by 0320 it read 81.8% RH, the 0300 reading being 81.63% RH and the 0330 reading being 81.81% RH. This event repeated at the 0630 and 0815 scans during the verification test, in both instances the sensor returned to normal readings within two minutes. The sensor was allowed to stabilize and the data was corrected manually in both computer pregrams.

This sensor was monitored closely for the remair.dcr of the tes.t but never exhibited any erratic behavior. other than the times noted. Subsequent to depressurization cable continuity and resistance checks were immediately conducted on the suspect cables and_ connectors. Results compared favorably to those performed prior to the test. The sensor was also examined and resistance substitution checks performed all with favorable results. The sensor electronics and DAS internal wiring will be checked thoroughly during the post test calibrations with results appropriately annotated in the Procedure Log.

During the test the RCIC exhaust steam check valve on penetration MC-41 developed a bonnett leak. The leakage rate was quantified even though it was being accounted for in the calculated containment leakage rate. This ,

penetration was not aligned in POST LOCA configuration and a _ full discussion appears in Section 3.0 and 4.0.

Subsequent to the ILRT the NRC raised the question that the main steam tunnel sub volume may not be adequately modeled by its assigned temperature sensors.

The area cooling units, in this sub volume, were in operation prior to the temperature survey thus reducing the temperature of the surrounding concrete to approximately 66*F,.even with both access doors remaining open. The adjacent areas remained at 71.9'F. This volume is a relatively small volume resembling the RWCU heat exchanger rooms. The steam tunnel and heat exchanger rooms both allow air to stagnate, hence the only effective means to add heat to the surrounding concrete and entrapped air is by conduction. For purposes of asertaining the effect, it was decided to simulate the steam tunnel volume fraction utilizing the Bechtel ILRT computer program. The Steam tunnel represents a volume fraction of 0.012 in the overall 0.165 for subvolume D so the volume fractions assigned to RTD 13, 14, 15 were reduced to 0.038 and RTD l 16 was reduced to 0.039 still totaling 0.165. Simulated sensor RTD 25 was L assigned to the steam tunnel. Since the RWCU hent Exchanger Room was being used as a conservative model the following data was compiled:

Four models were used to simulate the effect of additional temperature sensor RID-25 placed in the steam tunnel and assigned a volume fraction of 0.012.

The starting temperature was 69'F and the ending temperature was 70*F, both of which are conservative for if RTD-25 modeled RTD-10 the starting temperature would be 69.31*F (66.69 + 2.62*F) and the ending temperature would be 69.67'F (69.31 + 0.36).

Case No. 1 Assumed that RTD-25 remained at a constant 69'F.

Case No. 2 Assumed that RTD-25 exhibited a linear temperatures increase of 0.04*F/Hr from 69.31 to 69.67'F.

Case No. 3 Assumed that RTD-25 exhibited a linear increase from 69'F to 70*F.

Case No. 4 Assumed that RTD-25 exhibited a linear increase from 69'F to 70*F with 4 temperature perturbations.

For each of the above cases a summary report, trend report, total time analysis, and mass point analysis as well as a Plot of RTD 25 appears in Appendix D. The worst case results show a 0.004 %/ day increase to the total time UCL and 0.006 %/ day increase to the mass point UCL, these results are insignificant and as such are not included in the reported leak rate.

Penetration System Leakage Rate IMC-41 RCIC Exhaust Steam Check Valve 0.10 gpm**

- Penetration MC-41 is designed to be sealed with Suppression Pool water for a minimum of 30 days Post LOCA, hence it is tested with water and not additive to the Containment Integrated Leakage Rate.

During the ILRT, Valve IE51-F041 (the outboard check valve) leaked at a rate of 700 ML/ MIN. @P since this resulted in a respective small level decrease in Suppression Pool level and a corresponding decrease in containment pressure the leakage was included in the Containment Leak Rate. This is conservative as water leakage is not required to be added to the Integrated Leak Rate.

700 ML/ MIN = 0.185 gpm = 1.483 CFH which resulted in a 40.04 cu. ft.

volume reduction in Suppression Pool level during the 27 hour3.125e-4 days 0.0075 hours 4.464286e-5 weeks 1.02735e-5 months test evolution.

4.0 ANALYSIS AND INTERPRETATION 4.1 ILRT Test During the ILRT, the following penetrations were not in post-LOCA alignment. The penetrations together with their Type C leakage rates are given below:

TOTAL 1251.74 SCCM (0.0442 SCFM)

Penetration MC-41 is tested with water as it is designed to be sealed with suppression pool water post LOCA hence the leakage experienced during ILRT, is included within the containment leak rate, which is conservative.

4.2 The total leakage rate correction for penetrations not in post-LOCA alignment and water volume changes is 0.007 %/ day.

I The calculated leakage rates during the ILRT were 0.253 %/ day (mass point) and 0.255 %/ day (total time). The calculated 95% upper confidence limits were 0.259 %/ day (mass point) and 0.286 %/ day (total time).

, Adding the total leakage rate correction for penetrations not in post-LOCA alignment and containment water volume changes yields the corrected leakage rates as follows:

Leakage Rates, %/ day Mass Point Total Time

, Leakage Rate UCL Leakage Rate UCL Calculated 0.253 0.259 0.255 0.286 Corrections 0.007 0.007 0.007 0.007 Corrected 0.260 0.266 0.262 0.293 Since the corrected 95% upper confidence limits for both mass point and total time are less than 0.75 La (0.4875 %/ day), the test results demonstrate that

. the leakage through the primary containment and systems and components penetrating primary containment does not exceed the allowable leakage rated specified in the Clinton Power Station, Unit 1 FSAR and Technical Specifications.

APPENDIX A ILRT Computer Program Summary l

[

APPENDIX A ILRT Computer Programs Two computer programs were available during the test the Bechtel ILRT computer program and the Illinois Power Corp ILRT computer program. The Bechtel program is the official program of record, the Illinois Power Corp. program was utilized to collect data and to provide a baseline against the Bechtel program for its future use. Leak Rate Summary Data for the Illinois Power Corp. program is presented in Appendix D and E for direct comparison against the Bechtel test results.

1.0 DESCRIPTION

OF BECHTEL ILRT COMPUTER PROGRAM A. Program and Report Description

1. The Bechtel ILRT computer program is used to determine the integrated leakage rate of a nuclear primary containment structure.

The program is used to compute leakage rate based on input values of time, free air volume, containment atmosphere total pressure, drybulb temperature, and dowpoint temperatureg (water vapor pressure). Leakage rate is computed using the Absolute Method as defined in ANSI /ANS 56.8-1981, " Containment System Leakage Testing Requirements" and BN-TOP-1, Rev. 1, " Test.ing Criteria for. Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants". The program is designed to allow the user to evaluate containment leakage rate test results at the jobsite during containment leakage testing. Current leakage rate values may be obtained at any time during the testing period using one of two computational methods, yielding three different report printouts.

2. In the first printout, the Total Time Report, leakage rate is computed from initial values of free air volume, containment atmosphere drybulb temperature and partial pressure of dry air, the latest values of the same parameters, and elapsed time. These individually computed leakage rates are statistically averaged using linear regression by the method of least squares. The Total Time Method is the computational technique upon which the short duration test criteria of BN-TOP-1, Rev 1, " Testing Criteria for integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plant", is based.

3. The second printout is the Mass Point Report and is based on the Mass Point Analysis Technique described in ANSI /ANS 56.8-1981,

" Containment System Leakage Testing Requirements". The mass of dry air in the containment is computed at each data point (time) using the Equation of State, from current values of containment atmosphere drybulb temperature and partial pressure of dry air. Contained mass is " plotted" versus time and a regression line is fit to the data using the method of least squares. Leakage rate is determined from the statistically derived slope and intercept of the regression line.

4. The third printout, the Trend Report, is a summary of leakage rate values based on Total time and Mass Point computations presented as a function of number of data points and elapsed time (test duration). The Trend Report provides all leakage rate values required for comparison to the acceptance criteria of BN-TOP-1 for conduct of a short duration test.

Relative liumidity sensors are used at Clinton.

5. The program is written in a high level language and is designed for use on a micro-computer with direct data input from the data acquisition system. Brief descriptions of program use, formulae used for leakage rate computations, and program logic are provided in the following paragraphs.

B. Explanation of Program

1. The Bechtel ILRT computer program is written, for use by experienced ILRT personnel, to determine containment integrated leakage rates based on the Absolute Method described in ANSI /ANS 56.8-1981 and BN-TOP-1.
