1.0 INTRODUCTION

On November 22 and 23,1993, the Illinois Power Company (IPC) successfully completed the Integrated Leakage Rate Test (ILRT) and the Drywell Bypass Leakage Rate Test (DBLT) on its Clinton Power Station (CPS) Unit I reactor containment building. Both tests demonstrated that the measured leakage rates for the primary containment and drywell do no exceed the allowable values specified in the CPS Updated Safety Analysis Report (USAR) (Reference 1) and the Technical Specifications (Reference 2).

The ILRT and DBLT were conducted in accordance with the requirements of the ILRT procedure (Reference 3), Appendix J to 10CFR50 (Reference 4), ANSI /ANS 56.8 (Reference 5), BN-TOP-1 (Reference 6), and ANSI N45.4 (Reference 7). The nominal test pressures for the ILRT and DBLT were 9.0 psig and 3.0 psig, respectively. Leak rates were calculated using the absolute method, which uses a direct application of the ideal gas law (PV=mRT). The Total Time version described in ANSI /ANS 56.8 was employed to determine the leak rate and the 95% Upper Confidence Limit (UCL) for the ILRT. A similar method was used in determining the leak rate for the DBLT. The test duration was 8.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months for the ILRT and 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for the DBLT.

Suppression pool and drywell sump level changes were monitored continuously throughout both tests to determine the real time free-air containment and drywell volumes. During the Verification Test, the suppression pool level monitor indicated a significant increase in pool level and, consequently, a corresponding increase in the leak rate was indicated. This monitor was determined to be unreliable after verifying that the level increase did not coincide with actual plant conditions. All data from this level m c/.or were subsequently rejected and initial and fmal suppression pool levels were obtained manually, consistent with previous ILRTs. The drywell sump level monitors were found to be reliable throughout the ILRT and DBLT and their data were used in calculating the free air volumes Due to an oversight in the revision to the Instrument Air (IA) test lineup, the Safety / Relief Valve (SRV) accumulators ucre not depressurized during the ILRT and DBLT. A conservative calculation was therefore performed to determine the maximum leakage from the accumulators into the drmell/ containment that could have occurred during testing.

This calculated leakage was added to the ILRT and DBLT leak rate results. A summary of the test results and the corresponding allowable values are provided below. The leakage rates reported below include minimum path leakage rate correction for those penetrations not lined-up for the test, corrections for water level changes during the tests, and corrections for the pressurized SRV accumulators. (See Section 4.0).

2.0 TEST SYNOPSIS Prior to performing the ILRT and DBLT, all pressure, temperature, humidity, and flow sensors were calibrated to their speci6ed accuracy. To ensure proper response of these sensors aner their installation, an in-situ test was conducted as required by ANSI /ANS 56.8 - 1981. Table 1 of Section 3.0 tabulates the location of all temperature and humidity sensors installed inside the containment and drywell.

In accordance with 10CFR50, Appendix J, the containment was isolated by lining up systems penetrating containment in their post-accident con 6guration, except those systems listed in section 3.C.12 of this report. Also, prior to the ILRT, the containment and 3 drywell liners were inspected to assess their pre-test condition. No abnormal degradation I or change in appearance was noted during this inspection.

Pressurization of the containment for the ILRT commenced at 1840 hours0.0213 days 0.511 hours 0.00304 weeks 7.0012e-4 months on November 21,1993, and was secured at 0130 hours0.0015 days 0.0361 hours 2.149471e-4 weeks 4.9465e-5 months on November 22,1993 when test pressure was achieved. Temperature stabilization immediately followed and stabilization criteria were met 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months later (see Appendix B for temperature stabilization data.). The ILRT ofTicially started at 0530 on November 22,1993, and was conducted for a duration of 8.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months (see Appendix D for ILRT data). The Mass Point calculated leak rate was 0.0729Ydday with an upper confidence limit of 0.0835H/ day. The Total Time calculated leak rate was 0.0726Ydday with an upper con 6dence limit of 0.1639Ydday. Both upper confidence limits, after adding a leakage correction of 0.0565H/ day, were below the allowable leakage rate of 0.4875Ydday (75% of La). The Total Time calculations satisfied all short duration test requirements of BN-TOP-1, and the Mass Point calculations satis 6ed all short duiation test requirements of ANSI /ANS 56.8-1981.

Aner pressurization for the ILRT, a walk down of the containment revealed. water draining from the vent paths for penetrations IMC-052 (FC Supply) and IMC-064 (RWCU Return to FW A & B). Since a proper vent path could not be provided for these two penetrations as required by 10CFR50, Appendix J, the penetrations' minimum path leakage rates, measured prior to the ILRT, were added to the calculated leakage rate totals (see Section 4.0). Both penetrations were len in their normal test lineup throughout the ILRT.

The veri 6 cation test commenced at 1400 hours0.0162 days 0.389 hours 0.00231 weeks 5.327e-4 months on November 22,1993. A superimposed leak rate approximately equal to La (13.08 scfm) was continuously vented from containment through a calibrated flow meter to validate the ILRT results. Aner a one hour stabilization period, the altered containment leakage rate was measured for a duration of 4.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months . The Mass Point and Total Time calculated leakage rates were 0.7595 Ydday and 0.7421 Ydday, respectisely. Both leakage rates were within the calculated upper and lower limits (0.5604 to 0.8854 Ydday -- Mass Point and 0.5601 to 0.8851 H/ day -- Total Time).

Approximately midway into the verif cation test, the calculated leakage rate began to trend I upward and ultimately exceeded the allowable upper limit A review of the data revealed that suppression pool level indication had increased significantly (approximately one inch (5000 gallons) over two hours) over the same period of time. After confirming with the Main Control Room that water had not been added to the suppression pool during the test, the cause for this trend was attributed to erroneous level data from the suppression pool level monitor. Post-test calibration of this level monitor later confirmed that it was out-of-3

calibration. Conwyently, the on-line suppression pool level data for the ILRT and verification test were rejected and the suppression pool level was determined manually consistent with previous ILRTs. The two other similar level monitors used to measure the drywell floor and equipment drain sump levels functioned reliably and were used in the calculation of the containment and drywell free air volumes.

Data reduction and leakage rate calculations for the ILRT and verification tests were accomplished using the BCP Technical Services, Inc., ILRT Computer Program, Rev. 2.

Prior to using this software, a Software Acceptance Test was conducted that validated its application for performing calculations required for the ILRT. A summary of this computer program is provided in Appendix A.

After the verification test, pressure was lowered to approximately 3 psig in the drywell and to atmospheric in the containment. The Drywell Bypass Leakage Rate Test commenced at 1115 hours0.0129 days 0.31 hours 0.00184 weeks 4.242575e-4 months on November 23,1993, and continued for five hours with a one hour stabilization penod. Using the absolute method, the leakage rate calculated for the DBLT was 29.33 scfm. This leakage, after adding a leakage correction of 0.90 scfm, was below the allowable leakage rate of 4,312 scfm. The test data and leakage rate calculations are presented in Appendix H. Following the DBLT, the drywell was depressurized and plant systems and equipment were restored.

During the restoration, it was discovered that none of the 16 Safety Relief Valve (SRV) accumulators had been depressurized prior to conducting the ILRT and DBLT.

Consequently, any leakage from these accumulators would have masked leakage of the containment and drywell. Thus, a calculation was performed to detennine the maximum amount of air that could have leaked from the accumulators during the testing. Using conservative assumptions of the initial and final accumulator pressures and in the calculation of the pressurized volume, the maximum total leakage rate from the SRV accumulators during the ILRT was calculated to be 0.90 scfm. The details of this calculation are contained in Section 4.0.

11, Containment Water Volume Changes During The ILRT Containment floor and equipment drain sump pits were flooded prior to the test so that water drainage to these pits would overflow to the suppression pool, As previously discussed, suppression pool level was monitored manually due the unreliable data reccised from the digital level monitor. RPV and suppression pool level changes were determined to be negligible; therefore, corrections to the

! calculated leakage rates were not required. i The drywell floor and equipment drain sump levels were monitored continuously during the ILRT using the digital level monitors and were used in calculating the Total Time and Mass Point leakage rates. The changes in sump levels and in the corresponding containment free air volume are listed below.

b. SRV Accumulators i

Due to a procedural deficiency, the SRV ADS and non-ADS accumulators were not vented to j atmosphere prior to the start of the ILRT. The maximum amount of air that could have leaked into '

containment during the ILRT was calculated to be 25561 scem or 0.9026 scfm. Below are the ;

assumptions made in calculating the maximum accumulator leakage. The leakage calculation can '

be found in Appendix D, ILRT Calculations.

I i

1 The initial pressure of the accumulators was assumed to be 160 psig. This is highest pressure found during the accumulator check valve operability surveillance (CPS No. l 9061.11) performed in RF-4.

l

2. The fmal accumulator pressure was either measured with a calibrated gauge (when the !

associated accumulator had not been recharged during test restoration) or it was assumed to be a containment pressure at the end of the ILRT (9.280 psig). Actual pressure was measured for nine of the 16 SRV accumulators.

3. Accumulators were assumed to be at full pressure at the start of the ILRT and leak at a l constant rate until reaching their fmal pressures. The fmal pressure for accumulators that had been recharged was assumed to be reached at the end of the ILRT.

4. The volume of the accumulators and associated piping up to the check valve was determined by review of the isometric drawings. A 10% error in the volume of piping was utilized to account for minor construction differences, piping smaller than 1 1/4", and fittings (elbows, tees, valves, etc.).

l

5. Temperature was assumed to remain relatively constant during the pressure decay.

IMC208 A 04/26/93 13:20 20.000 1 10.00 LLRT was performed to identify the cause for the increase in leakage of the last test. Identified that the leakage recorded last time 1/7/93 on 1SX097A was due to leakage past the 1SXO95A not the containment isolation valve. MWR D30636 was written to repair this valve and the procedure was PDR'ed to remove the ISXO95A as a pressurization boundary.

This is indicated as an excessive leakage for ISI criteria however the acceptance criteria for ISI has been increased to 20000 SCCM and the acceptance criteria in this data sheet has not yet been revised to reflect the new acceptance criteria.
