l I. INTRODUCTION i j The initial periodic Containment Integrated Leak Rate Test on the primary containment structure of the Duke Power Company Catawba Nuclear l Station Unit 2 Pressurized Water Reactor was successfully completed on March 18, 1989. The ILRT was conducted in conformance with the l requirements of 10CFR50 Appendix J (and associated ANSI standards) and Catawba Technical Specifications. A 24-hour test was performed utilizing the absolute test method and mass point data analysis technique with the 1 containment pressure > 14.68.psig (calculated peak containment accident pressure). The results were verified by the satisfactory completion of a j superimposed leak rate test. I Analysis of final test data shows the results to be well within the specified limits for this containment. The acceptance criterion for this test is that the containment integrated leakage rate be less than 0.225 percent by weight of the containment air mass per day for both the "As-Found" and "As-Left" cases. The actual test results are 0.0243%/ day for the Type A Leaksge Rate (95% UCL Leakage Rate + Leakage Penalties + 1 Leakage Savings). The Leakage Rate was the same for "As-Found" and i' "As-Left" because the ILRT was conducted at the beginning of the outage. The Leakage Savings was 0.0000%/ Day for this test (See Appendix E). { 1 1 l 1 I i l i i 1 i b

0.' II. TLST BACKGROUND INFORMATION 1 1 A. Description of Containment I The Catawba Unit 2 Containment System' consists of a free-standing steel containment vessel surrounded by a separate concrete reactor building.. A~six foot annular space is provided between the outer wall of the containment vessel and the inner wall of the reactor i building to allow filtration of containment vessel leakage during accident conditions to minimize off-site doses. The following containment vessel specifications are used as base data for the containment leak rate test. I 3 l Containment Net Free Volume 1,172,618 ft Design Pressure 15 psig Calculated Peak Accident Pressure 14.68 psig Test Pressure > 14.68 psig Test Temperature Ambient Maximum Allowable Leakage Rate (L,) 0.3 weight %/ day B. Description of ILRT Instrumentation The containment system was equipped with instrumentation to pe.mit leakage rate determination by the absolute method. Utilizing 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 (W) is calculated according to the ideal gas law as follows: W = (P-Pv)V RT Where: P = Containment Absolute Pressure I Pv = Partial Pressure of Water Vapor V = Containment Net Free Volume R = Gas Constant T = Containment Absolute Temperature The primary measurement variables required are containment absolute l ] pressure, containment dewpoint temperature and containment temperature as a function of time. During the supplemental verification test, containment bleed-off flow is also recorded. j 1 l i I i 2 I l

1 52 Resistance Temperature Detectors, 6 Dewpoint Hygrometers, and 3 Pressure Sensors are installed at predetermined locations in the containment vessel to allow determination of weighted average temperatures, vapor pressures, and pressures. For analysis purposes, the containment is divided into three compartments, with the following specifications: Volume

1 Upper Containment 0.595 13 2 1 Ice Condenser 0.134 15 2 1 Totals 1.0 52 6 3 1. Pressure Instrumentation i Three precision pressure gauges were installed outside the containmer.t vessel, with pressure tubing connecting each gauge to its applicable compartment ' containment penetration. The gauges used were Ruska Model 6000-801-40 psia gauges, with the following specifications: Range: 0 to 40 psia Repeatability: 24 Hr: 1 0.0008 psi I 90 Day: 0.0016 psi Accuracy: (0.01% Full Scale + 0.011% Reading) or better, traceable to NBS .i Sensitivity: 1 0.002% FS Output: DC Analog Out.put (0-4 v) to Digital Meter for display and fluke data acquisition system. 2. Temperature Instrumentation Fifty-two precision Resistance Temperature Detectors were located throughout the containment to allow measurement of the weighted average air temperature. The locations of the RTDs i are'shown in Appendix C. The RTDs used were Rosemount Model j No. 78S, with the following specifications: i l Range: 0 to 200*F j Repeatability: 1 0.025% over entire range Accuracy: 1 0.45 F over entire range j Sensitivity: 0.09*F Element: Platinum i Resistance: 100 ohms at 32*F (nominal) l i i s j

L,: & 3. Humidity Instrumentation Six Dewpoint Temperature Analyzers were located in containment. } '(Each. compartment had two dewpoint cells installed'at'different locations within the compartment.) The locations of the . dewpoint cells are also shown in Appendix C. The instruments used were EG&G Dewtrack Model 200, with the following .i specifications: [l Range:.-40.0 to 140 F 1 Accuracy: i 1*F,' traceable to NBS f Sensitivity: 1 0.36*F worst case Output: 4-20 mA 4. Data Acquisition Facility l The data acquisition system consists of a Fluke 2289A computer j

front end and a Fluke 2281A extender chassis, which interfaces j

with the. IBM System 2 Model 80 computer. The required cards i and pertinent data are listed below. Absolute Pressure - DC Voltage Measurement I Cards Required: 161 High Performance A/D-162 Thermocouple /DC Volts Scanner 175 Isothermal Input Connector Range: 8 VDC Resolution: 73 pV (sensitivity) Accuracy: 1 0.01% Reading, 800 pV.for 1 year calibration 1 0.005% Reading, 700 pV for 90 day calibration Repeatability: 10.003% Reading, 300 pV 'DewToint - DC Current measurement Cards Required: 161 High Performance A/D. 162 Thermocouple /DC~ Volts 171 Current' Input' Connector Range: i 64 mA Resolution: 0.6 pA (sensitivity) j Accuracy; i 0.5% Rdg, i 5 pA for 1 year j l Repeatability: 0.015% Rdg, 2 pA Temperature - RTD Resistance Measurement Cards Required: 161 High Performance A/D 163 RTD/ Resistance Scanner ) 177 RTD/ Resistance Input Connector Range: 256 ohms Resolution: 2.4 mohms (sensitivity) Accuracy: 10.0175% Rdg, i 5.7 mohms for 1 year cal.

5. Flow Instrumentation A rotameter was used to impose the leak during the verification test. The rotameter used was a Brooks Model #1110 with the following specifications: Range: 0 - 5.86 SCFM Repeatability: 0.5% FS Accuracy: 1.0% FS, traceable to NBS 6. Instrumentation Selection Guide (ISG) Calculation The Instrumentation Selection Guide is an acceptable method to verify the ability of the instrumentation system to measure the containment integrated leakage rate. The ISG formula is described in American National Standard ANSI /ANS-56.8-1987. The maximum allowable value for the ISG is 0.25 L, or 0.075%/ day'for Catawba. The ISG calculated for tftis test (24-hour duration) was 0.0174%/ day. The ISG calculated for an 8-hour duration was 0.0522%/ day. C. Description of Computer Program The ILRT Program actually consists of two separate programs. The main program is called LEAK.EXE. This is a totally generic program, in that this program may run at any station with no changes required. Its " personality" is derived from a configuration file, which must be developed for each test. The ILRT Program contains the tools needed to create and edit the configuration file. The I second program is called DATACQ.EXE. This program provides the I interface to the data acquisition system. Although, it must be custom written for each data acquisition system, it does not contain any test-specific information. All it has to be able to do is establish communication with the data acquisition system, provide commands to the data acquisition system, and send the results back to LEAK. ] Test parameters to be measured are pressure, dewpoint temperature, ) and dry bulb temperature inside the containment. Instrument readings by the data acquisition system are recorded on the hard disk of the computer. From this data, the leak rate is calculated l by the computer. All data, raw and calculated, can be displayed on the computer monitor. Use of the absolute pressure method as described in ANS N45.4-1972 is the basis for the leakage calculations performed by the ILRT System Program. The primary methodology is.nass point analysis as described in ANSI /ANS 1 56.8-1987. The secondary methodology is the total time calculation as described in BN-TOP-1. A description of the calculations performed is given in Appendix A. l 5 l lu____ t

As a. result, very little type B&C leak rate testing was ~ -done prior'to ILRT. The tests performed prior'to ILRT are listed' l below. A tabulation.of the leakage savings resulting from this. testing can be found in Appendix E. M346 As Found LR for.

In addition to the installation of the data acquisition system and i instrumentation, preparation for the ILRT included inspections of 3 the interior and exterior surfaces of the containment vessel and the l reactor building interior. The inspection of the reactor building. exterior was performed after the ILRT. These inspections,Lperformed by Duke Power Company Design Engineering / Civil Group, were completed q on 4/19/89. Another test prerequisite was the performance of'a temperature survey, required by both ANSI N45.4-1972 and ANSI /ANS-56.8-1987 to verify the proper location'of'the RTDs in containment. The temperature' survey was performed per procedure PT/2/A/4200/01U, and was satisfactorily completed on 3/16/89. Operations alignment of containment penetrations was completed on 3/16/89, and pressurization of the Containment Vessel commenced at 1015 hours on 3/16/89. (A list of the containment penetrations not exposed to test pressure can be found in' Appendix D.) The average l pressurization rate was approximately 2 psi / hour. Pressurization was secured at 1820 hours on 3/16/89. The temperature l stabilization phase was started at 1830. During the temperature l stabilization period, a soap bubble test was performed on all hot ciechanical penetrations as required by Catawba Technical Specifications. Also, leakage survey teams were dispatched to search ~for any leakage paths from containment. No significant leaks were identified. 7 =

The temperature stabilization criteria of ANSI /ANS-56.8-1987 were met at 2230 hours on 3/16/89, at which point the ILRT was initiated. After 24 hours of data accumulation, all acceptance criteria were met using the Mass Plot method, and the ILRT was officially . terminated at 2231 hours on 3/17/89. Following removal of a containment air sample by Health Physics, a leak was imposed on the containment v.ssel through a containment pressure transmitter tubing sense line (one of the permanent containment pressure transmitters, independent of the ILRT pressure instrumentation). The imposed leak test started at 22:56 on 3/17/89 and was successfully completed at 02:56 on 3/18/89. The depressurization of containment commenced at 03:39 on 3/18/89. The primary flowpaths were through IVY 34 to the annulus and a VQ line to the unit vent (modifications had to be performed to the VQ line to permit flow through this line to the unit vent). Due to a high concentration of noble gases in containment, one of the planned vent paths (a VQ line to the open VQ filter units on 543 elevation of the Auxiliary Building) could not be used. Due to the slow rate of depressurization, the upper airlock door seals were deflated at 08:30. (The discharge through thesa door seals is to the annulus.) With these paths, depressurization was completed at 1500 on 3/10/89. No equipment damage was found during the post-ILRT containment inspection. There were no instrumentation failures during the performance of the test. B. Analysis and Interpretation 1. Temperature Stabilization Containment ventilation fans were run during pressurization to aid in mixing the containment air. Due to the cool ambient conditions, the approximate average compartment temperature rise during pressurization was only 3.1 F. As a result, containment temperature stabilized rapidly, and the stabilization criteria of ANSI /ANS-56.8-1987 were me". within the minimum four hour period. 8 10

2. Pressure Decay (24 Hour) Test Due to the highly stable conditions inside containment following the temperature stabilization period, coupled with the leak-tightness of the containment penetrations (no significant leaks were found by the leakage survey teams), the 95% Upper Confidence Limit Mass Point Leakage Rate was well below the acceptable limit after only four hours of data accumulation. However, in order to meet current Appendi;: J requirements, the test was conducted for'a duration of 24 hours. The mass point results were as follows: Measured Leakage Rate: 0.0196%/ day 95% UCL Leakage Rate: 0.0239%/ day Leakage Rate: 0.0243%/ day (95% UCL + Leakage Savings + Leakage Penalty) Acceptance Criterion: 0.225%/ day (75% of L,) It may be worth noting that although the measured leakage using the Total Time Method was acceptable after 8 hours of data accumulation, the 95% UCL leakage using the Total' Time Method (with BN-TOP-1 short duration acceptance criteria) did not meet the acceptance criterion until 18 hours irto the test. One thing noted from the plots for the 24 hr test was the spikes in ice condenser average vapor pressure. These spikes correspond to the defrost cycles that the ice condenser air handling units were set for. The units defrost approximately 30 minutes every six hours. The individual spikes occur every six hours as well as indicating that this was the cause. 3. Superimposed Leak Rate Test A superimposed leak equivalent to 0.2980%/ day was added to the existing containment leakage using the turbine flowmeter. After 4 hours of data accumulation, the verification test was i terminated with the following acceptable results: 1 Minimum acceptable Measured Leakage Rate: 0.2426%/ day (24-Hour Test Measured Leakage Rate + Superimposed Leak Maximum acceptable M$a)sured Leakage Rate: Rate - 25% of L 0.3926%/ day (24-Hour Test Measured Leakage Rate + Superimposed Leak Measured Leakage Rat $)during Verification Test: Rate + 25% of L 0.3319%/ Day l l l 9 11

Total Time Leakage' Rate Calculation .The' Total Time method calculates a series of leakage rates based on the starting mass ~ point and the most recent mass point (i.e. it, calculates a leakage' rate.between data points 1 & 2; then between 1 & 3; and so on). Each successive leakage calculation is based upon a longer period of time. The overall leakage rate,

in weight percent per day, at any given time is determined by applying linear regression analyses to the leakage rates-at'each time point.

The leak rate corresponding to each data point is determined from equation 3.1. 144,000 Li= I tg where:- Lg = measured leakage rate based on the difference between the initial mass at time t and the mass at time t (Note: the normaliked mass at at time t =1),g(wt. %/ day) tf==normalizeelapsedtimesincefirsthea(Ndkn=g,W(bin} ) mass at time t /W N i = 2 to n;;where n = number of (N ,t pairs) g g Page 8 of 16 50 _ R-m _

The following three statistical tests have been proposed to the NRC staff as a method for determining the acceptability of mass pointLleakage results for test durations less than 24 hours.

The first of these tests is the Maximum Window Leakage Criterion.. This^ routine calculates the leakage rate, using the mass point methodology,'for all time intervals (windows) equal to 1/2 or 11/3 of the-test duration and records the valt-of the maximum leakage. The default vclue for the program is the 1/2 window leakage calculation, which has been submitted to the NRC staff 'for review. The 1/3 window leakage calculation option is also available'if desired. The window time interval is calculated by multiplying the elapsed time between the first reading and the last reading (reading n) by the window multiplier (1/2 or 1/3). Using the first reading as a starting point for the leakage calculation, the program uses the data acquisition frequency and subsequent iterations to find the da.ta set having an elapsed time most closely matching Page 11 of 16 SE A-11 _ = - _ = _ _ _ _ _ _z_____

av v the window time interval". This data set is called the 'end reading' 'and represents the latest edge of,the window . calculation. The leading edge of the window calculation is referred to as the 'berin reading'. Using the Mass-Point Method. for determining leakage rate described by Section 2.0 of this i Appendix, the measured-leakage rate (Lam) is calculated through 1 all data points from 'begin reading' to 'end reading'. j j! The 'begin reading' is then advanced by one reading. The 'end reading' is advanced, such that the time span between the 'begin' ] and 'end' rea' dings most nearly approximates the time interval of the window; the leakage rate is then recalculated. The window leakage calculations a;e repeated until the 'end reading' is equal to the last reading of the test duration (reading n). The maximum. measured leakage rate (Lam) generated by the sequential' window leakage calculations is the 1/2 or 1/3 maximum window leakage value for this test duration. The test data satisfies this-criterion at the point when the 1/2 or 1/3 maximum window leakage _valuc'is less than 0.75 L,. The second statistical test is the Limit on Data Scatter as described by Condition 2 of the NRC draft Regulatory Guide l MS 021-5. This test ensures a tight fit of the test da.:a about j the linear least squares fit regression line used by tr.e nass point method to calculate the leakage rate. The test is acceptable when inequality 4.1 is met. Page 12 of 16 gq A-12

The Predictor Criterion as outlined in T.M. Brown's and L.E. Estenssoro's paper, " Suggested Criteria for a Short Duration -ILRT" is the third statistical test performed on the test data. Satisfying this criterion ensures that the measured leakage rate -(L,,) and the. 95 percent. upper confidence limit (UCL) are 4 Page-13 of 16 53 A o p 1 converging.- In _ addition, the predictor equation will-provide j reasonable assurance that'the leakage rate reported following i I test-termination will result in the verification ~ test' meeting its; ] o acceptance criteria.

Manually determine the corrected value for the superimposed leak rate, (Lo) to account for differences between calibration i temperature and pressure and actual flow conditions.

IE Information Notice 85-71 requires both As-Found (Pre-Maintenance) and As-Left (Post Maintenance) leak rate tests on penetrations performed during the outage. Because ILRT was performed at the beginning of the outage, there was no maintenance work performed on any penetrations, therefore, no As-Found leak rate tests were conducted because of maintenance. The only As-Found leak rate tests conducted were the VP valves and the equipment hatch. The total leakage savings (which is added to the measured As-Left ILRT Result, yielding the total As-Found ILRT Result) is calculated by summing the differences between the As-Found minimum pathway leakage rate and the As-Left minimum pathway leakage rates for all affected penetrations. Below is a tabulation of the Leakage Savings realized during the Unit 2 EOC-2 refueling outage prior to ILRT. The leakage rates listed are corrected for I instrument error. Because the leakage savings was negative, a conservative value of zero was used for addition to the measured ILRT results. As-Found As-Left Min. Pathway Min.

U l Since the preoperational Type A Test performed on' Catawba. Unit 2'in June and July of 1985,;1ocal leak rate testing.was conducted in accordance with 10CFR50 Appendix J'and the station Technical Specifications. During this time period, the' summation of the Type B and C leakage rates averaged less than l8,000SCCM,whichiswellbelowthe.acceptancecriterionof55,877SCCM. The maximum Type B~and C leakage; rate total over this time period was 10,204.5 SCCM, which still represents less than 0.11 L. It should be noted that L was changed from 0.2%/ day to 0.3%/ day in Febr0ary 1988 resulting in an-a acceptance criteria of 82,979 SCCM. Attached are three printouts listing leakage rates for all Type B and C penetrations: ' Printout #1 lists a summary of As-Left~ leakage rates for Unit 2 Post Preoperational ILRT prior to coraercial operation. - Printout #2 lists the As-Left leakage rates for the Unit 2 EOC-1 refueling outage, and Printout #3 l lists the As-Left leakage rates for the Unit.2 EOC-2 refueling outage. The " Reported Leakage" for each' penetration is the Maximum Pathway leakage rate. When the measured leakage rate is less than the lower (threshold). limit for which the Volumetrics. Leak Rate Monitor is calibrated, the calibration lower limit is. reported as the leakage rate. Acceptance Criterion 11.2 on Page 11 of the printouts addresses penetrations which are " Bypass; Leakage Paths". (i.e., Any leakage through these penetrations would escape both the Containment Vessel and the Reactor Building, bypas' sing the Annulus.) Acceptance Criterion 11 3 addresses the Containment Purge System penetrations. Below is a summary of the Type B and C penetrations which failed the local leak rate test since the last ILRT. In these instances, although the Maximum Pathway Leakage Rate might have exceeded the acceptance criterion of 0.6 L, the Minimum Pathway Leakage Ratas were always well below the acceptable limits. The list does not incluJe failures of valves being retested following maintenance, or failures of the Containment Purge System valves after they had been opened. (These large butterfly valves, which are opened only during plant shutdown, have a 50% probability of leak rate test failure following ' cycling. It is for this reason that an As-Found LRT on all of the purge valves was performed prior to opening them.)
