1. LNTRODUCTION The Reactor Containment Building Integrated Leakage Rate " Type A" Test is performed to demonstrate that leakage through the primary reactor containment systems and components penetrating primary reactor containment do not exceed the allowable leakage rates specified in the Plant Technical Specifications.

The purpose of this report is to provide information pertinent to the activities related to the preparation, test performance, and reporting of the Limerick Generating Station Unit 2 Integrated Leakage Rate Test (ILRT).

Highlights of activities and events which occurred prior to and during the ILRT are presented in Section II, Test Synopsis.

Section III, Test Data Summary, contains data and results necessary to demonstrate containment atmosphere stabilization, acceptable leakage rate, and a successful verification test. In addition, plots provided in Appendices B and C supply a visual history of containment atmospheric conditions beginning with the ILRT test period and ending with the verification test.

O Information in Section IV, Analysis and Interpretation, supplies the technical details -

associated with the ILRT computer program and its associated hardware as well as the instrumentation used during the ILRT.

Section V, References, lists the documents used for the conduct of the ILRT.

The successful periodic Type A and verification tests were performed according to the requirements of the Limerick Generating Station Unit 2 Technical Specifications and 10 CFR 50, Appendix J. The test method used was the Total Time Method, as described in ANSI N45.4-1972, " Leakage-Rate Testing of Containment Structures for Nuclear Reactors" and Bechtel Topical Report BN-TOP-1 Revision 1, " Testing Criteria for Integrated Leak Rate Testing of Primary Containment Structures for Nuclear Power Plants."

Leakage rates were calculated using the Total Time Analysis technique. Mass Point i Analysis equations from ANSI /ANS-56.8-1987, " Containment System Leakage Testing Requirements" were run concurrently for informational purposes. The test results are i reported in accordance with the requirements of 10 CFR 50, Appendix J, Section V.B3.

TEST SYNOPSIS Prior to commencing containment pressurization at 0355 (first data point at 0415) on March 9,1993, site personnel were engaged in prerequisite activities for the conduct of the ILRT. The ILRT was conducted at the end of Limerick Unit 2's second refueling outage. 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 ILRT procedure review and finalization, ILRT computer program checkout and linkup to the Volumetrics A-100 Data Acquisition System, ILRT instrumentation calibration, installation, and operability checks. A containment temperature survey had been performed prior to the test in the ventilation lineup used for the ILRT.

The ILRT test procedure was reviewed against the requirements of the Plant Technical Specifications; 10 CFR 50, Appendix J; BN-TOP-1; ANSI /ANS-56.8-O 1981; and recent plant modifications.

The ILRT instrumentation was calibrated prior to the ILRT as recommended by ANSI N45.4-1972, Sections 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.

i PHILADELPHIA ELECTRIC COMPANY GENERAL PHYSICS CORPORATION Limerick Generating Station Unit 2 ILRT GP-R-643-93-008 C. Containment Pressurization Containment pressurization started at 0355 on March 9,1993 using three 1500 cfm diesel-driven 100% oil-free air compressors. The pressurization rate was maintained at approximately 6-7 psi per hour. This was within the procedural limitation of 8 psi per hour. The pressurization rate was gradually reduced as the containment pressure approached 44 psig by reducing the number of operating compressors. All compressors were stopped when the containment pressure reached 61.4 psia (46.7 psig) at 11:53, on March 9,1993. This was within the procedural limits of 44.0 +3, -0 psig. During pressurization a containment walkdown was performed to identify potential leakage. No excessive measurable leakage was observed. Pressurization was conducted with the use of the Reactor Containment Fan Cooling Units until rising fan motor currents required them to be secured at 0830 on March 9,1993.

D. Containment Atmosphere Stabilization The stabilization phase was started at 1200 on March 9,1993. By 1600 on March :

9,1993, the temperature stabilization criteria of ANSI /ANS-56.8-1987 and BN-TOP-1 had been met. Prior to the test, it was determined that the acceptance criteria of .75 L awas equivalent to about 4 lbm per 15 minute reading. Mass swings at the beginning of stabilization were between 16 and 9 lbm during 15 minute readings. Eventually, this began to taper off to a change of 9-12 lbm/ reading and appeared to be steadily decreasing over the last hour's readings.

Based on this trend and having met the temperature stabilization criteria, the conditions supported starting the test.

E. ILRT Test Period i i

The ILRT was officially started at 1800 on March 9,1993. Almost immediately j I

after starting the test, the observed downward trend reversed itself and stabilized at a higher value. Excessive leakage (approximately 3-4 times the acceptance criteria as determined at 15 minute intervals) was detennined to exist early on in the test as mass swings settled out. Initial investigations for leakage yielded a ,

number of small leaks which were left as they were. It was determined that the !

combined magnitude of these smallleaks did not approach the magnitude of the -l computer determined measured leakage rate. This magnitude ofleakage would be typical for a large volume between inboard and outboard isolation valves or inside air locks that were equalizing. This was the case in a few of the monitored areas, but again, evaluated independently or combined, these leaks were not determined to be excessive.

PHILADELPHIA ELECTRIC COMPANY GENERAL PHYSICS CORPORATION Limerick Generating Station Unit 2 ILRT GP-R-643-93-008 E. ILRT Test Period (Continued)

Investigations continued while the test was still being conducted. It was later determined that Suppression Pool level that was "the same", by earlier reports, had actually changed by what experience dictated was a significant amount (over 1 inch in 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months ).

New investigations were made into the possible sources of liquid level loss from the Suppression Pool. The safeguards keep-fill pump was decided on as the most likely problem. At 2130 on March 9,1993 discussions started on the ramifications of securing the safeguards keep-fill pump. At 2315, after a shift change, the decision had been made and implemented to secure the suspect pump to aid in troubleshooting.

Observation of the next few data points showed that leakage had dropped down to about one half of the allowable rate. Operations was requested to keep the pump secured for the remainder of the test. A contingency plan was developed for the possibility of restarting the pump for ECCS. The containment had by now been stabilized with no major perturbations since 1600 on March 9,1993. It was concluded that safeguards piping fill was removing approximately 15 gpm from the suppression pool and discharging to the condenser. A decision to abort the present test and restart a new test was made.

A new test was started at 0100 on March 10, 1993 and was successfully completed at 0715 on March 10,1993. The maximum allowable leakage rate (La) for the containment is 0.5 wt.%/24 hours with a test acceptance limit of 0.375 wt.%/24 hours (0.75 La). Total Time and Mass Point Analyses were run concurrently on the General Physics ILRT Computer Program. The leakage rate results are as follows:

Verification Test After the required one hour hold between imposing the known leak and taking four hours of data, a successful verification test was conducted following the ILRT. At 0715 on March 10, 1993, a leakage rate of 5.67 scfm (corrected for actual versus calibration conditions) was imposed on the primary containment. !

The leakage imposed (Lo) on the existing containment was slightly less than La (0.5 wt.%/24 hours) at 0.4998 wt.%/24 hours. The verification phase was I completed at 1245 on March 10,1993.

The drywell was depressurized to an approximate differential pressure of 4.23 psid corresponding to the approximate submergence of the downcomer vents. (Initial depressurization to 4.5 psid with a minimum of 4.0 psid during the two hour test.) The calculated maximum differential drywell to suppression pool pressure (based on the height of water in the downcomers and a conversion to psi) for the test conditions was 5.0 psid (before all water was forced out of the downcomer vents). Depressurization was kept below the procedural limitation of 8 psig per hour. The first data point was taken at 2115 on March 9,1993. After two hours of data, at 2315 on the same day, the bypass test was satisfactorily completed.

Using the Total Time technique, the calculated orifice size was as follows:

BYPASS ACCEPTANCE TEST RESULTS CRITERIA 2

Measured Orifice Size 0.01065 in (First to Last Data Point)

Calculated Orifice Size 0.01089 in2 50.72 in2 (Entire Test)

The calculated orifice size had originally been reported as 0.02284 square inches, which was still well belovi the acceptance criteria. Due to a data handling problem with the bypass test compuar code, the average drywell and suppression pool weighted temperatures were calculated incorrectly. This error was found in the.

bypass test computer code during General Physics' standard post-test data review.

This portion of the code is independent from the ILRT code and does not affect other sections of the program.

The data handling program code was modified to accept a greater number of inputs (sensors) in September 1992, after its last use at Peach Bottom. The December 1991 Peach Bottom bypass test results were successfully verified. The Peach Bottom data and results were thus not affected. Prior to the test at Limerick, hand calculations required by the General Physics software installation procedure were made to verify only the ILRT portion results. The Bypass test is an independent section of code which is only used on Philadelphia Electric Company-BWRs. The modification to accept a greater number of inputs in September 1992 was not expected to impact the calculation of an equivalent orifice size when it was installed and verified. Retest guidelines in September 1992 only ensured that the ILRT portion of the code was properly operating. The Umerick test was the first time that the bypass program had been used since then. The retest requirements at that time therefore did not include the independent hand calculations that have now been implemented.

The revised orifice size calculations are smaller than the originally reported values by a factor of greater than two. Thus, the error was in the conservative direction.

The programming for the bypass test is plant specific and thus no other ILRTs that this code was used for were affected. The computer code has since been modified in accordance with the requirements of General Physics' Software Control Procedure. Using the same raw sensor data, the new modified program code results matched 100% in a comparison to hand calculations performed by two separate individuals.

ANALYSIS AND INTERPRETATION The 95% upper 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.%/24 hours). Additions to the calculated leakage rates must be made to account for penetration paths not exposed to the ILRT pressure and for changes in the net free containment volume due to changes in containment subvolume water levels. These additions are discussed below.

DESCRIPTION OF GENERAL PHYSICS ILRT COMPUTER PROGRAM n

V 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 Volumetrics A-100 Data Acquisition System.

Two computers were brought 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 all required sensor data conversions if the data logger should cease to function. Each computer was equipped with back-up disks in the unlikely event of a disk " crash."

SECURITY -

The General Physics ILRT Computer Program is written in Microsoft's QuickBASIC Version 4.5. QuickBASIC is a high level programming language which combines v l 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 data editing routine to safeguard the integrity of the raw data files.

FEATURF3 The program itself is designed to be a menu driven program consisting of five ,

separate, menu driven operating modes. These are the:

1. Pressurization Mode 4. Verification Mode

2. Stabilization Mode 5. Depressurization Mode

3. Test Mode 6. Bypass 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 (7 program. Program organization consists of a master menu which controls access to V the seven operating modes chained to the individual menus which control these modes.

The data processing, information display capabilities and function of each mode is as E-1

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

including a superimposed acceptance criteria line).

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

5. Depressurization Mode: All data and graphics capabilities of Pressurization Mode. In programs for BWR units.

6. Bypass Mode: This mode includes a Drywell to Suppression Chamber Bypass Test routine which calculates an equivalent orifice size for Philadelphia Electric Company BWR Units.

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

1. Containment total pressure conversion fmm counts to psia (if required), and j averaging. I i

2. Containment drybulb temperature weighted averaging and conversion to ,

absolute units. i

3. Containment dewpoint temperature weighted averaging (conversion from Foxboro dewcell element temperature to dewpoint temperature if required) and i conversion to panial pressure of water vapor (psia).

4. Data storage of ILRT measurement system inputs for each data point.

2

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

O 6. Automated Data Acquisition and/or Manual Data Entry.

l E-2 ,

I

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

8. Calculation of ISO formula at beginning of test; acceptance criteria based on number of sensors remaining and actual test duration.

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

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 certi5 cation 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 acquisition system output to the computer printout data point summary.

t Taken from Bechtel authored 1989 Final Report Note 1 Long stabilization time while attempting to locate excessive leakage through two hydrogen recombiner trains and 'B' Recirculation Pump seal purge line. Temperature stabilization only took 4.0 hours0 days 0 hours 0 weeks 0 months .

Note 2 Safeguarda piping fill was removing approximately 15 gpm from the suppression pool and discharging to the condenser causing an aborted test until the Safeguards keep. fill pump was secured and the test reinitiated.

Note 3 Calculated from total time as-left leakage rate minus the sum of the 95% UCL leakage and the water

> b volume correction.

Note 4 Although not added into leakage for this test, HCU leakage was reported as 4529.8 seczn. Under similar conditions as in the 1993 test, this would convert to an addition of 0.014 wt.%/24 hours. I Note 5 Calculated from total time upper ihnit during the verification test of 0.827 wt.%/24 hours minus the sum of 25% of La (0.125 wt.%/24 hours) and computed leakage rate.

1.0 INTRODUCTION

Containment leakage rate testing is performed at the Umerick Generating Station using the absolute method of obtaining containment mass data, and the mass point or total time analysis techniques to analyze the data. The absolute method involves the determination of the containment air mass (weight) and the calculation of weight losscs during the ILRT by direct observation of containment pressure, temperature, humidity, and by the application of the ideal gas law.

The containment pressure during an ILRT is measured by a pair of precision pressure gauges which measure total pressure in absolute units. To make the application of the ideal gas law appropriate, the partial pressure exerted by the water vapor content of the containment air mass must be quantified and subtracted from the total pressure. Nine dew cells are used to obtain an average dewpoint temperature which can be converted to absolute pressure. The remaining component of the ideal gas law formula observed during an ILRT is temperature. Seventeen RTDs are currently used to derive an average containment drybulb .

temperature. A large number of sensors are ased because the containment is such a large volume; with several subvolumes of air whose individual temperature and dewpoint may not .

be represu.tative of the overall containment conditions. Some of these subvolumes are small and enclosed; like the reactor pedestal or drywell head areas. Others are large and open such as the sr , ession chamber. If a simple arithmetic mean was used to obtain the average Os drybulb amperature for use in the weight calculation, a sensor in the drywell head area measuring conditions in some 8,773 cubic feet would carry as much weight in the equation as v a sensor measuring conditions in 35,000 cubic feet in the drywell. Logic dictates that simple averaging of the sensor data is not appropriate, so weighting factors for drybulb and dewpoint sensor readings are employed.

Weighting factors are applied to the RTDs and dewpoint temperature sensor readings

- to achieve more representative measurements. Each weighting factor is based on the percentage of the containment free volume that the sensor is calculated to be monitoring (in communication with). The total of all volume weighting factors (or volume weighting fractions, VWF) is 1.00 for the drybulb temperature sensors. The dew cells have separately assigned weighting factors (also totaling 1.00) based on the percentage of containment free volume that they monitor.

O 1

i l

2.0 BASIS The containment has been divided into five zones based on clearly defined physical boundaries such as the suppression chamber, drywell head area, and floor areas. The net free volume of these zones has been calculated, and the fraction of the whole that they represent is determined. The fraction for each zone is then divided by the number of sensors in that zone to obtain a volume weighting fraction for the sensors in that zone. Table l' defines the zone's physical boundaries, the net free volume associated with each, the fraction of the whole each zone represents, the number of drybulb temperature sensors placed in the zone, and the >

. volume weighting fraction (VWF) assigned to each sensor in the zone. Table 2 defines the same parameters for the dewpoint sensors. Zone assignments and VWFs for the dewpoint sensors are different than those used for the RTDs because of the different number of sensors.

The use of VWFs improves the statistical value of the raw sensor data used in the air mass calculation. The weighted average values that result give a better representation of the conditions in the overall containment. If a sensor was declared failed prior to or at any time during the ILRT (up to and including' verification)it is required tha. the VWFs for the deleted sensors be reassigned and results recalculated. Table 3 provide. instructions for reassigning VWFs in the event of a single failure for drybulb sensors. Tath 4 provides similar instructions dewpoint sensors. Each table also includes instructions for applying a multiple failure methodology. The volume fraction reassignment methodology is based on the physical proximity of the failed sensor to the other sensors in that zone, or other zones if there is reasonable communication between the air volumes. Tables 3 and 4 reassignment instructions are based on an engineering assessment of actual sensor placement and air flow patterns. Figures 1 through 5 illustrate the sensor placement for the 1993 ILRT. These figu:es should be used to perform an engineering evaluation of any volume weighting factor reassignment beyor.d the guidance of Table 3 or 4.

O Single Failure Volume Weighting Fraction Reassignment (CONTINUED)-

A. Sincie Failure Analysis Methodology

1. Refer to Table 3 for Drybulb (RTD) Sensors. -

2. Refer to Table 4 for Dewpoint Sensors.

B. Multiple Sensor Failure Example - RTDs

1. Assume sensor 015F fails, then sensor 015H:

a. Go to Single Failure Weighting Fraction Reassignment Table (Table 3) and apply instructions for the loss of sensor 015F (i.e. change the MVF for 015F to 0.000, and change the MVFs for sensors: 015G to 0.093, 015H to 0.092,015J to 0.092,015K to 0.092, and 015L to 0.092)

b. When sensor 015H fails, take the current VWF for the failed sensor (0.092) and divide by the number of sensors from Table 3 that will

" share" the failed sensor's redistributed volume weighting fraction. This should be the total number of the remaining active sensors from sensor 015H's single failure instructions column (sensors 015G,015J,015K, and 015L). Thus,015H's current VWF divided by 4 remaining active sensors is 0.092/4 = 0.023. Now s&'. the result to the current VWF of the remaining sensors from sensor 015H's single failure instructions column. (i.e. change the VWFs for sensors: 015H to 0.000,0150 to 0.116,015J to 0.115,015K to 0.115, and 015L to 0.115)

Note: The methodology would be identical if sensor 015H failed first and then sensor 015F failed.

c. Any multiple sensor failure reassignment should undergo a second person review by the ILRT shift test director for accuracy and wacurrence with the methodology based on the remaining sensors.

d. The ILRT computer program automatically checks and volume fraction changes to assure a total of unity (1.000).

Single Failure Volume Weighting Fraction Reassignment I

(CONTINUED)

A. Sincie Failure Analysis Methodology

1. Refer to Table 3 for Drybulb (RTD) Sensors.

2. Refer to Table 4 for Dewpoint Sensors.

B. Multiple Sensor Failure Example - Dewpoint Sensors

1. Assume sensor 015A fails, then sensor 015F:

a. Go to Single Failure Weighting Fraction Reassignment Table (Table 4) and apply instructions for the loss of sensor 015A (i.e. change the VWF for 015A to 0.000, and change the VWFs for sensors: 015E to 0.151 and 015F to 0.151)

b. When sensor 015F fails, take the current VWF for the failed sensor (0.151) and divide by the number of sensors from Table 3 that will O. " share" the failed sensor's redistributed volume weighting fraction. This should be the total number of the remaining active sensors from sensor 015F's single failure instructions column (sensors 015C and 015E).

Thus,015F's current VWF divided by 2 remaining active sensors is 0.151/2 = 0.0755. Now add the result to the current VWF of the remaining sensors from sensor 015F's single failure istructions column.

(i.e, change the VWFs for sensors: 015C to 0.249, and 015E to 0.248)

Note: The methodology would be identical if sensor 015F failed first and then sensor 015A failed.

c. Any multiple sensor failure reassignment should undergo a second person review by the ILRT shift test director for accuracy and concurrence with the methodology based on the remaining sensors.

d. The ILRT computer program automatically checks and volume fraction changes to assure a total of unity (1.000).
