SUMMARY

A periodic Type"A" Integrated Leakage Rate Test (ILRT)was successf ully conducted on the primary containment structure of the Florida Power&Light Company St.Lucie Plant Unit No.1 Pressurized Water Reactor.This test was perf ormed at f ull pressure in accordance with the f acility Technical Specifications.

This ILRT test was perf ormed using the"Absolute Method" of testing in accordance with the Code of Federal Regulations, Title 10, Part 50, Appendix J,"Primary Reactor Containment Leakage Testing f or W ater-Cooled Power Reactors," in accordance with ANSI N45.4-1972, American National Standard,"Leakage Rate Testing of Containment Structures for Nuclear Reactors," and the methodology and calculational requirements of Topical Report BN-T(P-l, Revision 1,"Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants." The ILRT was performed at a pressure in excess of the calculated peak containment internal pressure related to the design basis accident as specified in the Final Safety Analysis Report (FSAR)and the Technical Specifications.

This report describes and presents the results of this periodic Type"A" leakage rate testing, including the supplemental test method utilized for verification.

In addition, Florida Power h Light Company performs Types"B" and"C" testing in accordance with the requirements of 10CFR50, Appendix J, and the Technical Specifications.

The results of types"8" and"C" testing performed since the last ILRT are provided in this report.The resulting reported"as-found'ype"A" containment leakage at 40.7 psig is 0 335 percent of the contained mass per day.This value includes the difference between the as-found and as-left minimum pathway Types"B" and"C" local leakage measurements as required by the NRC IhE Inf ormation Notice 85-71.Th resulting reported"as-left" Type"A" containmnt leakage at 40.7 psig is 0.130 percent of the contained mass per day.The acceptance criteria for this test, as contained in the facility Technical Specifications is that leakage cannot exceed 0.375 percent of the contained air mass per day for either the"as-found" or"as-left" case.

II.TEST DISCUSSION A.Description of the Containment The contairrnent vessel ccmpletely encloses the entire reactor and reactor coolant system to ensure no leakage of radioactive materials to the environment in the mlikely event of a hoss of coolant accident.The containment system design incorporates a free-standing containment vessel surrounded by a low-leakage concrete shield building.A four-foot annular space is provided between the outer wall of the containment vessel and the ironer wall of the shield building to allow filtration of containment vessel leakage during accident conditions to minimize off-site doses.The free-standing containment vessel is a two-inch thick right circular cylinder with a one-inch thick hemispherical dome and two-inch thick ellipsoidal bottom.The overall vessel dimensions are 140-f oot diameter by 232-foot high.The vessel wall thickness is increased to a minimun of four inches adjcent to all penetrations and openings.The vessel is fabricated of ASME-SA 516 Grade 70 fully killed pressure vessel quality steel plate.The net free volume of the containment vessel is 2.5 x 10 cubic feet.The contaiment vessel structure includes one personnel airlock, one emergency escape lock, one fuel transfer tube, one equipment maintenance hatch and one seal-welded construction hatch.All process piping and electrical penetrations are welded directly to the containment vessel nozzles with the exception of the main steam, main feedwater, and fuel transfer tube penetrations.

These penetrations are provided with testable multiple ply expansion bellows to allow for thermal growth or building differential motion.The containment vessel is d signed and constructed in accordance with the requirements for Class MC vessels contained in Section III of the ASME Code (1971 Edition).The containment vessel is code stamped for a d sign internal contairment pressure of 44 psig at a temperature of 264 F.The containment vessel and all penetrations are designed to limit leakage to less than 0.5 percent by weight of the contained air per day at the above design conditions.

The calculated peak accident pressure f or the design basis accident for the St.Lucie Plant Unit No.l is 39.6 psig.B.Description of ILRT Instrumentation The containment system was equipped with instruoentation to permit leakage rate determination by the"absolute method." Utilitizing this method, the actual mass of dry air within the containment is calculated.

The leakage rate becomes the time rate of change of this value.The mass of air (Q)is calculated according to the Perfect Gas Law as follows: Q=(P-Pv)V where: P-Containment Total Absolute Pressure Pv-Containment Water Vapor Pressure (Average)V-Containment Net Free Volume R-Gas Constant T-Containment Absolute Temperature (Average)The primary measurement variables required are containoent absolute pressure, containment relative hunidity, and containment temperature as a function of time.During the supplementary verification test, containment bleed-off flow is also recorded.Average containment absolute temperature is determined'y measuring discreet local temperatures throughout the containment and applying a mass and volume weighted averaging technique.

The volune fraction for each sensor is determined based~on solid geometrical calculations:

where: T-Containment Absolute Temperature (Average)Ti-Local Temperature for Sensor i Vfi-Volune Fraction for Sensor i Average containment water vapor pressure is determined by measuring discreet local relative humidities throughout the containment, converting this to local vapor pressures using local group temperatures and applying a mass and volume weighted averaging technique.

The volume f ractions f or the relative hunidity sensors are determined in the same manner as f or the temprature sensors above.(~).j Steam Table=Pv.j TLocal.j where: Pv-Containment Water Vapor Pressure (Average)Pvj-Calculated Local Vapor Pressure for Sensor j VFj-Volune Fraction for Sensor j T-Contairment Absolute Temperature (Average)TLocalj-Local Group Average Temperature iVear Sensor j (XfH)j-Relative Hunidity for Sensor j The Instrument Selection Guide or ISG is used to determine the ability of the instrumentation system to m asure the leakage rate.The calculated ISG for this test met all acceptance criteria for all test instrumentation systems.

1.Temperature Instrumentation Forty precision Resistance Temperature Detectors (RTDs)were located throughout the containment to allow measurement of the weighted average air temperature.

The location of the temperature detectors in the containment is depicted in Figure 1.Each RTD sensor was supplied with a calibrated resistance versus temperature curve accurate to+0.5 F.The sensitivity and repeatability of each RTD sensor is less than'+0.01 r.The signal conditioning circuit and readout for the RTD sensors was a Fluke 2280B data logger operating in a constant current mode.The operating parameters f or the RTD constant current card are accuracy of+0.16 F and 0 resolution of+0.01 F.0 Each RTD was in-situ calibration checked after installation to verify correct operation.

The data logger operating as a total loop with an RTD in the circuit had a repeatability of+0.02 F and a resolution of+0.01 F.0~0 2.Humidity Instrumentation Nine Resistance Humidity Detectors (RHDs)were located throughout the containment to allow measurement of the weighted average containment vapor pressure.An additional RHD was installed in the containment as a spare, in case one of the original nine RHDs failed.The location of the RHDs in the containment is depicted in Figure 2.The calibrated accuracy of the RHDs is+2.5 percent RH, the repeatability of the RHOs is+0.25 percent RH, and the sensitivity of the RHDs is+O.l percent RH.The readout device used for the RHDs was a Fluke 22803 data logger.The repeatability of this device is+0.01 percent RH while the resolution of the device is+0.01 percent RH.Each RHD was in-situ calibration checked after installation to verify correct operation.

3.Pressure Instrumentation Two precision quartz bourdon tube manometers were used to determine containment absolute pressure.The arrangement of tubing connections between the manometers and the contaireent is shown in Figure 3.Either manometer could be used as the primary pressure sensor for leakage rate calculations with the remaining sensor being considered as a backup.The calibrated accuracy of the manometers if+0.015 percent of reading.The sensitivity, repeatability, and resolution of the manometers is+0.0015 psi.Binary Coded Oecimal (BM)output from both manometers was.connected to the Fluke 2280B data logger.4.Flow Instrumentation A variable area float-type rotameter was used to superimpose leakage during the supplementary CLRT.The piping connection between the rotameter and the containment is shown in Figure 3.The accuracy, repeatability, and sensitivity for the rotameter in units of SCFM and converted to equivalent leakage values is given below: SCFM Peak Pressure Rotameter Accuracy+0.20 Repeatability

+0.05 Sensitivity

+0.05 5.Instrument Selection Guide (ISG)Calculation Equivalent Leakage+0.0031 I/day+0.0008 I/day+0.0008 I/day The Instrument Selection Guide is a method of compiling the instrumentation sensitivity and resolution for each process measurement variable used during the ILRT and evaluating the total instrunentation systems'bility to detect leakage rates in th range required.The ISG formula is described in American National Standard ANSI/ANS 56.8-1981.Although the ISG is a very conservative measure of sensitivity, the general industry practice as for this test has been to require sensitivity at least four times better than the containment allowable leakage or ISG~0.25La.

The calculated ISG for the instrumentation used for this test was 0.041 percent per day, for an 8.25-hour test.The allowable valu for this test is 0.25l a or 0.125 percent per day, for an 8.25-hour test.The ISG calculation met all recommended criteria and demonstrated the ability of the ILRT instrumentation system to measure containment leakage with a sensitivity exceeding that required by the appropriate industry standards.

C.Containment Pressurization Equipment The equipment used to pressurize the containment is shown in Figure 4.The ten oil-free industrial diesel-driven air compressors had a total nominal capacity of 11,000 ACFM.The compressed air was then routed to water-cooled aftercoolers, moisture separators, and refrigerant air dryers.This equipment assured that clean and dry air was used to pressurize the containment.

D.Description of the Computer Program The Ebasco ILRT ccmputer program is an interactive program written specifically for fast, easy utilization during all phases of the ILRT and CLRT.The program is written in a high-level, ccmpiled, structured language and is operated on a portable CP/M-based microcomputer.

The program has been verified and meets all requirements of the Ebasco Quality Assurance Program.As necessary, data entry and modifications are readily accomplished by the data acquisition team.In addition to extensive data verif ication routines, the program calculates, on demand, total tim and mass point leak rates as well as the 95 percent Upper Confidence Level for these leakage rate calculations.

Calculations and methodology of the program are derived from American National Standard ANSI N45.4-1972 and Topical Report BN-TCP-1, Revision 1.Containment air mass is determined from mass-weighted sensor readings as described in EFRI report NP-2726, November 1982.

Input data may be d leted for a given instrument in the case of a sensor malfunction.

This deletion of a given instrument is performed on all samples in the data base.Weighting factors, if applicable, are then recalculated for the remaining instrument sensors of that type.Data evaluations are enhanced by the flexible display of either sensor variables or various computed values in tabular or graphical f orm on the computer screen or printer.Data is recorded on magnetic media to prevent loss during th testing.All data is stored on the computer system in use, with retrieval capability to any desired data base throughout the testing.Ancillary portions of the program assist the user in detection of temperature stabilization, determining the ILRT termination criteria, performing ISG calculations, performing in-situ instrum nt loop performance calculations and detecting acceptable superimposed CLRT leakage verification.

Temperature, pressure, and humidity data are transmitted from the ILRT instrumentation system to the ccmp uter via an RS-232 link at 15-minute intervals.

Computer verification and checking routines supplem nt data verification by the data acquisition team.Modifications are promptly made when errors are detected.Prior to issuance of this report, further extensive data verification was perf ormed.

E.Description of the Testing Sequence During the current refueling outage, maintenance modifications to the containment electrical penetrations were made.Electrical penetrations C-8, D-l, 0-2, 0-3, and 0-9 were replaced.In addition, a spare penetration at location C-9 was converted to an operable electrical penetration.

Local leakage rate Type"B" tests were performed cn these electrical penetrations, both prior to and following the replacement.

All ILRT instrunentation was declared operable with perf ormance within manuf acturer'tolerances.

Pressure sensor No.2 was selected to be the primary pressure instrunent, as it had exhibited better repeatability and stability during the in-situ testing.Two penetrations were required to be in service during the ILRT and were not lined up to simulate accident conditions, P-523 (ILRT Pressure Sensing Line)and P-52E (ILRT Controlled Bleedoff Line).These two Il RT penetrations are used to conduct the test and cannot be positioned in the post-accident lin up.The minimum pathway leakage for those penetrations, determined during Type"C" local testing, is added to the measured ILRT leakage to account for these penetrations being in service during the test (refer to Appendix A).As a result of the Type"B" and"C" local leakage rate testing and repairs perf ormed during the ref ueling outage, additions to the"as-f ound" Type"A" ILRT results were necessary du to NRC Information Notice 85-71.These additions were f or the reduction in minimun pathway leakage due to repairs.These leakage reductions have been corrected for uncertainties prior to being added to the measured ILRT values (refer to Appendix A).Preparations to pressurize the containment for the conduct of the ILRT included internal and external inspections of the containment structure; installation and checkout of the ILRT instrumentation; Types"B" and"C" Local Leakage Rate Tests;alignment of valves and breakers for test conditions; and the installation and checkout of the temporary pressurization f acilities.

These preparations were completed early on March 20, 1987.

Pressurization of the containment structure started at 2120 hours0.0245 days <br />0.589 hours <br />0.00351 weeks <br />8.0666e-4 months <br /> on March 20, 1987, at an average pressurization rate of 3.4 psi/hr.Soon after the start'f pressurization, two temperature sensors were beginning to exhibit anomolous behavior.TE-40 (Elevation 194')displayed erratic readings on the data logger ranging from an open connection (high resistance) to-453 F.The diagnosed fault with TE-40 was loose connections 0 at some point in the containment.

Temperature sensor TE-40 was deleted from all computer calculations, and the remaining temperature sensors at that elevation received adjusted volume fractions.

The ISG calculations presented in Section II.B.5 were performed to accommodate the deletion of TE-40.The ISG value remained at 0.041 percent per day, well below the limit of 0.125 percent per day for an 8.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> ILRT.Temperature sensor TE-36 (Elevation 171'was noted to be reading 0 approximately 7 F below the other temperature sensors at that elevation, but exhibited stable behavior and was following the trend of the other temperature sensors at that elevation.

The decision was made not to officially delete temperature sensor TE-36 at this time, but to monitor its behavior during the balance of testing.During final stages of pressurization, leakage survey teams found evidence of small leaks at the leakage chases for the following penetrations:

P-9 Instrunent Air P-14 Nitrogen Su)ply P-26 CVCS Letdown All leakage from these paths was estimated to be less than 5 percent of the ILRT acceptance criteria, and no repairs or adjustments were made to these penetrations.

Pressurization was secured at 0957 hours0.0111 days <br />0.266 hours <br />0.00158 weeks <br />3.641385e-4 months <br /> on March 21, 1987, at a final pressure of 56.3 psia (41.6 psig).This pressure is 2 psi above the minimum test pressure to account for the expected pressure decrease due to temperature stabilization and to allow for some leakage margin during the test sequence.Data acquisition and analysis f or the temperature stabilization phase was begun at 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br /> on March 21, 1987.Plots of Containment Temperature and Pressure versus Time demonstrated smooth and expected behavior.The containment stabilization phase was declared acceptable at 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on March 21, 1987, after four hours of data acquisition.

All stabilization criteria contained in Topical Report BN-TOP-1 were met, and integrated leakage rate measurements were initiated at 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on March 21, 1987.At 1645 hours0.019 days <br />0.457 hours <br />0.00272 weeks <br />6.259225e-4 months <br />, after recording two-and-three-quarter hours of leakage rate data, it was determined that the leakage was trending above the"as-found" ILRT acceptance criteria at a 95 percent Upper Confidence Level.This measured leakage was below the acceptance criteria for an"as-lef t" ILRT, however.Leakage survey teams were dispatched to identify and quantify the containment leaks.The survey t ams identif ied the three 3eaks previously discovered, plus the following small leaks: P-28B Pressurizer Sample P-56 Hydrogen Purge Make~These leaks were determined to be of a small magnitude and in conjunction with the small leaks previously noted on P-9, P-14, and P-26, were not a cause of concern.No repairs or adjustments were made to any of the above leakage paths.At 2115 hours0.0245 days <br />0.588 hours <br />0.0035 weeks <br />8.047575e-4 months <br />, the leakage survey teams f ound that the contairment emergency sump suction isolation valves MV-07-2A and 2B were leaking air into the safety injection system.As these valves are not containment leakage paths in accordance with the FSAR and Technical Specifications, a decision was made to manually tighten these valves with no penalty to the"as-found" ILRT values.These valves were manually tightened shortly af ter 2130 hours0.0247 days <br />0.592 hours <br />0.00352 weeks <br />8.10465e-4 months <br /> on March 21, 1987, and the ILRT calculations restarted at the next data set (2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br /> on March 21, 1987).

After eight-and-one-quarter hours of ILRT data accumulation, all Topical Report BN-TOP-1 acceptance criteria for the ILRT were met with stable and predictable trends.The ILRT was officially terminated at 0600 hours0.00694 days <br />0.167 hours <br />9.920635e-4 weeks <br />2.283e-4 months <br /> on March 22, 1987.At 0606 hours0.00701 days <br />0.168 hours <br />0.001 weeks <br />2.30583e-4 months <br />, a superimposed flow equivalent to 0.318 I/day was initiated using the rotameter.

This flow was observed to be stable during the required BN-TOP-1 Controlled Leakage Rate Test (CLRT)stabilization period of approximately one hour.At 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br />, on March 22, 1987, the leakage rate measurements for the CLRT were initiated.

Stable and acceptable leakage rate measurements were made for four-and-one-quarter hours.At 1115 hours0.0129 days <br />0.31 hours <br />0.00184 weeks <br />4.242575e-4 months <br />, all Topical Report BN-TOP-1 criteria were met for the CLRT verification test, and the test was declared acceptable.

Depressurization of the containment structure was initiated at 1120 hours0.013 days <br />0.311 hours <br />0.00185 weeks <br />4.2616e-4 months <br /> on March 22, 1987, at a rate of 6 psi/hr.At 5.5 psig a containment entry was made during the depressurization to conduct the post-ILRT containment inspec-tion.The only damage observed included 11 broken light bulbs and hydraulic fluid leaking from two HVAC damper actuators.

The ILRT test sequence was officially terminated at 1945 hours0.0225 days <br />0.54 hours <br />0.00322 weeks <br />7.400725e-4 months <br /> on March 22, 1987, with less than three-quarters of a psig in the containment.

Subsequent to the ILRT, the containment sump suction valves MV-07-2A and 2B were reworked to adjust the motor torque switches.Proper closure of the valves was verified by functional testing.Inspection of the data from temperature sensor TE-36 (Elevation 171'after depressurization demonstrated the anomolous reading of 7 F below the other temperature sensors at that elevation persisted throughout the course of testing.The data from TE-36 exhibited stable behavior and was following the trend of the other temperature sensors at that elevation.

It is hypothesized that a high resistance developed in the compensating lead for the RTO, thus causing the low reading.It was decided to delete TE-36 from all calculations as its readings could not be justified.

All Temperature Stabilization, ILRT, and CLRT calculations were r vised following th deletion with no differences in the calculations noted.The ISG calculations of Section II.B.5 were performed to accommodate the deletion of TE-36.The ISG value remained at 0.041 percent per day, well below the limit of 0.125 percent per day for an 8.25-hour ILRT.

III.ANALYSIS AND INTERPRETATION A.Instrumentation S stem Performance Two of 40 temperature detectors failed during the initial stages of pressurization of the containment, as described in Section II.E.All of the remaining temperature detectors performed as expected with no anomolous behavior detected by the Ebasco ILRT computer program" error checking routines.This computer program also determines the in-situ temperature loop repeat ability which consists of process measurement variations as well as sensor noise.The average in-situ loop repeatability for the 38 operating temperature sensors was 0.009 F, with the worst sensor exhibiting an in-situ loop repeatability of 0.024 F.This perf ormance compares well with the vendor-claimed temperature sensor loop repeatability, excluding process variations, of 0.02 F as given in Section II.B.1.Ten relative humidity sensors were installed in the containment for the Il RT, even though the signal conditioning circuitry would only process signals for nine channels.The tenth sensor was maintained as a spare in the event one of the operating sensors failed.The nine operating channels for humidity operated as expected with no anomolous behavior detected by the ILRT computer program error checking routines.The average in-situ loop repeatability for the relative humidity sensors was 0.039 percent RH, with the worse sensor exhibiting an in-situ loop repeatability of 0.092 percent RH.This performance is substantially better than the vendor-claimed humidity sensor loop repeatability, excluding process variations, of 0.25 percent RH as given in Section II.B.2.Two pressure sensors were installed for the ILRT, with one utilized for testing and one considered as a spare.Prior to containment pressurization, computer analysis demonstated that pressure sensor 2 was more stable over an eight-hour period than the other sensor.During the ILRT, the in-situ pressure loop repeatability for both sensors was 0.0018 psi.This performance compares well with the vendor-claimed pressure sensor loop repeatability, excluding process variations, of 0.0015 psi as given in Section II.B.3.The variable area rotameter perf ormed as expected with no evidence of unstable readings, float sticking, or moisture in th float tube.In summary, all of the ILRT test instrumentation performed in an adequate manner to allow determination of containment leakage rates to the sensitivity required.B.Temperature Stabilization Phase Prior to pressurization of the contairment, the atmosphere was very stable with an average temperature of 77.38 F and a maximun spread of 0 temperature from the highest reading sensor to, lowest reading sensor of 0 5.5 F.During pressurization, the heat of compression of the air occurs mainly at the top of the containment with colder pressurization air being added at the bottom.At the end of pressurization, the average temperature was 90.67 F with a maximun spread of temperature f rem the highest reading 0 sensor to lowest reading sensor of 22.9 F.0 The results of the f our-hour temperature stabilization phase are presented in Appendix B.2.The acceptance criteria given in Topical Report BN-TOP-1, Revision 1, are described in Note 2 in that appendix.The data presented shows that a smooth and predictable temperature stabilization occurred.At the end of stabilization, the average temperature was 84.34oF with a maximum spread of temperatue from the highest reading sensor to the lowest reading sensor of 12.8 F.This demonstrates that the heat sinks of 0 concrete and steel in the containment were quickly returning the containm nt atmosphere to a stable condition.

C.Leakage Survey Phase Small leaks were found on five penetrations by leakage survey teams during containment pressurization and temperature stabilization, as described in Section II.E.These leaks were, of such a small magnitude as to not impact acceptance of the leakage rate test and were not adjusted or repaired.Leakage rate measurements on the containment were begun after the temperature stabilization phase using the total tice leakage rate methods of Tooical Report BN-TG'-1, Revision l.As an additional diagnostic tool, mass point leakage rate measurements, as described in ANSI/ANS 56.8-1981, were conducted in parallel.The mass point leakage calculations are not sensitive to the starting point of the test and will detect changes in containment leakage more rapidly than the total time method.As presented in Appendix A, a containment measured leakage rate of no greater than 0.170 percent per day at the 95 percent upper confidence level was the maximum rate which would allow an acceptable"as-found" ILRT.After two-and-thr e-quarter hours of accumulating leakage rate data, both the total time and mass point leakage rate calculations were measuring leakage above the"as-found'LRT acceptance criteria.A sugary of these results at two-and-three-quarter hours is: BN-TOP-1 Total Time ANSI 56.8 Mass Point Simple Leakage Rate 0.184 I/day Fitted Leakage Rate 0.206 I/day Upper Confidence Level 0.243 I/day 0.184 I/day 0.199 R/day 0.228 X/day Due to the short measurement interval, these leakage measurements should not be considered as final accurate measurements, but an indication of the order of magnitude of leakage present in the containment.

Leakage survey teams were dispatched in a coordinated manner to identify the source of high"as-found" ILRT leakage.It should be noted that this measured leakage would pass an"as-left" ILRT as presented in Appendix A.

Leakage measurements were continued as the leakage survey teams searched for the source of excessive"as-found" leakage.Computer analysis using both the total time method and mass point method demonstrated the presence of a steady leakage rate that would stabilize at a value b tween 0.28 I/day to 0.31 X/day.Leakage calculations at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> and 2115 hours0.0245 days <br />0.588 hours <br />0.0035 weeks <br />8.047575e-4 months <br /> on March 21, 1987, demonstrated increasing leakage values and a leakage survey team reported that a large leak on both containment emergency sump suction lines had been found by venting air from the outboard side of isolation valves MV-07-2A and 2B.Observations by the leakage survey team allowed for the possibility that these two emergency sump suction isolation valves were not fully closed.These two isolation valves are, not considered as potential leakage barriers in the Final Saf ety Analysis Report (FSAR)Sections 6.2.4.2 and 6.2.4.4, as they will be water covered in a Loss of Coolant Accident and open during the recirculation phase of the transient.

Any water leakage through these valves in the closed position will be returned to the containment by the Safety Injection System pumps.No potential containment leakage or off-site dose is credible due to seat leakage of these valves in the closed position.These two isolation valves were then manually closed with subsequent containment leakage rates significantly reduced as described in th next section.D.Integrated Leakage Rate Phase Leakage measurements were started after isolation of valves MV-07-2A and 2B at 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br /> on March 21, 1987.Stable leakage rates were measured by both the total time method and mass point method.The total time BN-TCP-1 results for eight-and-one-quarter hours of leakage measurements are presented in Appendix B.3.A summary of the measured leakage by both methods after eight-and-one-quarter hours is:

BN-TOP-1 Total Time ANSI 56.8 Mass Point Simple Leakage Rate 0.102 I/day Fitted Leakage Rate 0.077 I/day Upper Confidence Level 0.130 I/day 0.102 X/day 0.086 I/day 0.098 I/day The higher Upper Confidence Level of the BN-TOP-1 measurements is due to the nature of performing regression analysis on simple 3eakage rates instead of regression analysis on masses and the more conservative statistics utilized by BN-TG'-1.The measured leakage rates and upper confidence levels for both calculated methods were slowly decreasing with time.As all acceptance criteria for a Reduced Ouration BN-TCP-1 ILRT were met at eight-and-one-quarter hours as presented in Appendix B.2, the ILRT was declared acceptable.

Appendix A presents the corrections to the measured ILRT leakage rates for local leakage rate measurements for both the"as-found" and"as-left" cases.E.Verification Controlled Leakage Rate Phase Subsequent to the acceptance of the ILRT results, a superimposed leakage equivalent to 0.318 percent per day was added to the existing containment leakage using the variable area rotameter.

A one-hour stabilization period was allowed to lapse after addition of this leakage in accordance with the requirements of Topical Report BN-TOP-l.Leakage measurements were initiated to verify the results of the ILRT.The minimum duration for the Controlled Leakage Rate Phase was determined to be four-and-one-quarter hours in accordance with Topical Report BN-TCP-l.As presented in Appendix B.4, the leakage measurements met the acceptance criteria for the verification phase.Leakage results for both the total time and mass point method is:
