. GP-R 263110 GENERAL PIlYSICS CORPORATION II. TEST SYNOPSIS Prior to containment pressurization on March 26,1991, site personnel were engaged in prerequisite activities for the conduct of the ILRT. Local leakage rate testing was completed and those components with excessive leakage were repaired and retested.

The results of the local leakage rate tests are presented in Appendix F.

The following discussion highlights some of the activities that were essential to the successful and timely completion of the ILRT. These items are presented in chronological order.

A. Pre-pressurization Activities These activities included completing local leakage rate tests, ILRT procedure review and finalization, ILRT computer program checkout and linkup to the Volumetrics Data Acquisition System, ILRT instrumentation operability checks, and containment subvolume weighting factor and sensor failure analysis calculation.

. The ILRT test procedure was reviewed against the requirements of the Plant-Technical Specifications; 10CFR50, Appendix J BN TOP-1, Rev.1,1972, and ANSI /ANS 56.8-1987.

L The ILRT instrumentation was calibrated prior to the ILRT as recommended by ANSI N45.4-1972, Section 6.2 and 6 3. Final ILRT instrumentation operability checks and in-situ checks, as specified in ANSI /ANS 56.8-1987, Section 4.2.3.1, were performed to ensure that all instrumentation was operating correctly. Calibration records for the ILRT instrumentation system components are retained at the plant. ,

. GP R-263110 GENERAL PilYSICS CORPORATION C. Containment Pressurization Containment pressurization started at 1050 on March 26,1991 using three 1200 scfm portable diesel-driven 100% oll free air compressors. The pressurization rate was maintained at approximately 5.5 psi per hour until containment pressure reached 49 psig. At this time the pressurization rate was reduced to approximately 3 psi per hour, by stopping two of the three compressors. The third compressor was stopped when containment pressure reached approximately 50.7 psig at 2110 on March 26,1991. This was within the procedural limits of 49.1 +2,-0 psig.

During pressurization, a containment walkdown was performed to identify potentialleakage. No measurable leakage was observed. The pressurization, ILRT, and verification test were performed with the use of drywell fans and chilled water supply to the fan coolers. No temperature stratification was observed. One drywell fan tripped off on high current during pressurization and was not restarted.

D. . Containment Atmosphere Stabilization The stabilization phase was started at 2110 on March 26,1991. Prior to the completion of the four hour hold at 2300 on March 26,1991, the temperature stabilization criteria of BN-TOP-1 and ANSI /ANS 56.8 had been met and preliminary leakage rate calculations indicated very low leakage. However, at approximately 2330, a drywell cooling fan tripped off resulting in a -

temperature excursion. Ammeter measurements were taken on the remaining operating drywell fans which revealed that they were operating at or in excess of their thermal overload trip setpoints. Drywell cooling fans had been run for previous ILRTs with no problems. However, a recent modification was 5 j

L e GP-R-263110 GENERAL PIIYSICS CORPORATION made at Peach Bottom to upgrade electrical bus voltage levels. The higher operating currents observed during this ILRT were most probably a result of that modification. To prevent furth:r temperature excursions,it was decided to shut down all operating drywell cooling fans and allow the containment to reach a new equilibrium condition. As the RHR system was operating in Shutdown Cooling at a temperature of approximately 130 degrees F and providing a significant heat source, temperature stabilization had still not been reached by 1200 on March 27,1991. At 1300 hours0.015 days 0.361 hours 0.00215 weeks 4.9465e-4 months , it was decided to prepare a temporary modification to replace the drywell cooling fan thermal motor overloads with a larger size and restart the drywell cooling fans. At approximr.tely 2100, the ILRT Test Coordinator was informed by Operations that the Reactor Vessel Head Fiange temperature was decreasing and that there was a Technical Specification limit of 70 degrees F. Operations requested either that the drywell cooling fans be turned off or RHR temperature be increased. Since turning off the drywell cooling fans would result in another long restabilization period, it was decided to increase RHR temperature. By 2330 on March 27,1991, the containment air temperature stabilization criteria had been met and it was decided to r. tart the ILRT test period at 0000 hours0 days 0 hours 0 weeks 0 months on March 28,1991. At approximately the same time, the Operations Department increased RHR temperature at a rate of approximately 2 degrees F per hour. An additional adjustment was also made at approximately 0250 on March 28,1991. The increased RHR temperature resulted in an increase in the Reactor Vessel water level. By approximately 0600 on March 28,1.991, it became evident that due to the very low level of containment leakage, the increasing Reactor Vessel water level was causing the leakage rate calculations to indicate a negative leakage rate. At a meeting with Operations,it was decided to raise RHR temperature to a range of 150 to 180 degrees F to maintain Reactor Vessel Head Flange temperatures well above Technical Specification limits. After this was 6

, GP-R-263110 GENERAL PIIYSICS CORPORATION accomplished, Operations would maintain a steady control of the RilR temperature. By 1830 hours0.0212 days 0.508 hours 0.00303 weeks 6.96315e-4 months on March 28, 1991, all evolutions had been accomplished and all containment air temperature stabilization criteria had been met.

E. ILRT Test Period The ILRT was officially started at the next data point at 1845 on March 28, 1991 after the stabilization criteria had been met. During the stabilization period, one moisture sensor in the Torus was indicating a dewpoint temperature above the drybulb temperature. As a result, moisture sensor No.

5 was removed (by use of the weighting factors) from the ILRT and verification data. The ILRTwas successfully completed at 0245 on March 29, 1991. The maximum allowable leakage rate (L,) for the containment is 0.5

% wt. per day with a test acceptance limit of 0.375 % wt per day (0.75 L,).

The Mass Point and Total Time Analyses were run concurrently on the General Physics iLRT Computer Program. The containment leakage rate data met all the requirements of DN-TOP-1, Rev.1, necessary to end the test in less than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . During the ILRT and verification test, sensor data was

. continuously monitored and plotted in order to detect sensor malfunctions.

The leakage rate results are as follows:

_g.. .

. GP-R-263110 GENERAL PHYSICS CORPORATION F. Verification Test A successful verification test was conducted following the ILRT. At 0258 on March 29,1991, a leal: age rate of 4.57 scfm was imposed on the primary containment and allowed to stabilize for one hour. The verification phase started at 0400 on March 29,1991 and was completed at 0800 on the same day. The 4.57 scfm leakage imposed (Lo) on the existing containment leakage was slightly more than L, (0.500 % wt./ day) at 0.5071 % wt. per day.

The verification test results are presented below:

l Subsequent to the ILRT and the verification test, the Drywell-to-Torus Bypass Area Test (DTBAT) was conducted. The test started at 1627 on March 29, 1991, and was successfully completed after 2.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months . The calculated bypass area was determined to be 0.127 square inches. The maximum acceptable bypass area, as stated in the Peach Bottom Atomic Power Station Technical Specifications, is equivalent to a 1.000 inch I.D. orifice or 0.785 square l- inches.

. GP-R-263110 GENERAL PIlYSICS CORPORATION IV. ANALYSIS AND INTERPRETATION The upper 95% confidence limit (UCL) Total Time and Mass Point leakage rates calculated during the ILRT were less than the test acceptance criteria of 0.75 La (0.375 % wt./ day). Additions to the calculated leakage rates must be made to account for penetration paths not exposed to the ILRT pressure and foi changes in the net free containment volume due to changes in containment water levels. These additions are discussed below.

A. Type C Penalties Penetration paths not exposed to the ILRT pressure and the corresponding minimum pathway leakage rates are as follows:

, GP R 263110 GENERAL PilYSICS CORPORATION DESCRIPTION OF GENERAL PilYSICS IIRT COMPlTIER PROGRAM The following paragraphs describe the various features and attributes of the General ,

Physics ILRT Computer Program and the process used to certify it for each application.

REDUNDANCY <

-The General Physics ILRT team _was equipped with two fully operational IBM compatible. microcomputers during the ILRT and for on site data reduction and analysis. The computer software and hardware interfaced directly with the ILRT Measurement System Data Acquisition System (Volumctrics A 100).

Two computers were brour,ht on site for 100% redundancy, as each computer and its software is capable of independently performing the ILRT. The General Physics ILRT Computer Software is also capable of accepting manual input of raw sensor data and performing au required sensor data conversions if the data logger should cease to function. Each computer was equipped with back up discs in the unlikely event of a dise " crash."

SECURITY The -General Physics ILRT Computer Program is written in IBM's BASICA.

BASICA is a high level programming language which combines programming ease with user oriented command functions to create an-easy-to use and understand program. In order to increase speed of operation the program was then compiled into an executable command file. Compiling was accomplished using the IBM Basic Compiler. In addition to execution speed, this had the added benefit of making the program more secure as compiled programs cannot be edited or changed. The program requires a password to change modes of operation, start times, or enter the l_

data editing routine to safeguard the integrity of the raw data files.

FEATURES The program itself is designed to be a menu driven program consisting of five separate, menu driven operating modes. These are the: i

1. Pressurization hiode 4. Verification Mode

2. Stabilization Mode 5. Depressurization Mode

3. Test Mode These modes also correspond to the phases of the ILRT. Menu driven means that the user is presented with a list of options that the program can perform and from which the user can choose it allows for interactive information exchange between the user and the computer and prevents invalid information or user mistakes from crashing the program. Program organization consists of a master menu which centrols access to the five operating modes chained to the individual menus which control these modes. The data processing, information display capabilities and function of each mode is as follows:

1. Pressurization Mode: All data reduction,- graphic displays of average temperature, dewpoint, and corrected pressure.

2. Stabilization Mode: All data reduction, automatic comparison of data against ANSI 56.8 and BN-TOP-1 temperature stabilization criteria, notification when criteria is met, grapnic displays of average temperature, dewpoint, and l corrected pressure.

3. Test _ Mode: All data reduction, calculation of leakage rates using mass point,-

total time and point to-point analysis techniques, display of trend report information required by HN-TOP-1, graphic display of average temperature, i

dewpoint, pressure and mass, as well as graphic display of mass point measured leakage,95% UCL; total time measured and calculated leakage and L the total time leakage rate at the 95% UCL (as calculated by BN TOP-1),

( including a superimposed acceptance criteria line).

1 1

GP.R.263110 GENERAL PilYSICS CORPORATION

4. ysrification Test Mode: With input of imposed leakage in SCFht automatically calculates and displays on graph and trend report the acceptance criteria band, plus all graphics displays available in test mode.

5. Depressuri7ation hiode: All data and graphics capabilities of Pressurization hiode, in programs for BWR units, this mode tho includes a Drywell to Suppression Chamber Bypass Test routine.

Other reduction and analysis capabilities of the General Physics ILRT computer program include:

1. Containment total pressure conversion from counts to psia (if required), and averaging.

2. Containment drybulb temperature weighted averaging and con' Jon to absolute units.

3. Co::tainment dewpoint temperature weighted averaging (conversion from Foxboro dewcell element temperature to dewpoint temperature if required) and conversion to partial pressure of water vapor (psia).

4. Data storage of ILR'I measurement system inputs for each data point.

5. Weight (mass) point calculations using the ideal gas law.

6. Automated Data Acquisition and/or hianual Data Entry.

7. Sensor performance and deviation information for sensor failure criteria, graphic display of individual sensor perfortnance for selected operating mode.

GP R-263110 GENERAL PilYSICS CORPORATION

8. Calculation of ISG formula at be" .ig of test; acceptance criteria based on number of sensors remaining ai,. actual test duration.

9. Computer System Error Functions automatically checks for error in incoming data, printer or disk drive faults.

1 l

The computer program used by General Physics has been previously certified for six tests at the San Onofre Nuclear Generating Station and over a dozen other ILRTs.

The initial certification required verification of the program through hand calculations and an independent review by Bechtel Power Corporation. After certification was completed, a calibration set of raw data was used to verify software of the program prior to usage. Additionally, once the computer was linked to the data acquisition system and a complete data stream was available, the input function of each mode of the program was verified by comparing the data .mquisition system output to the computer printout data point summary.
