The test was performed in accordance with 10 CFR 50, Appendix J, and the Quad-Cities Unit One Technical Specifications. For the second time at Quad-Cities a short duration test (less than 24 hours) was conducted using the general test method outlined in BN-TOP-1, Revision 1 (Bechtel Corporation Topical Report) dated November 1, 1972. The first short duration test was conducted on Unit One in Decembei, 1982. Using the above test method, the total primary containment integrated leak rate was calculated to be 0.2286 wt %/ day at a test pressure greater than 48 PSIG. The calculated leak rate was within the 0.750 wt 1/ day acceptance criteria (75% of L ). The associated upper 95% confidence limit was 0.2975 A wt %/ day. The supplemental induced leakage test result was calculated to be 1.2864 wt %/ day. This value should compare with the sum of the measured leak rate phase result (0.2286 wt %/ day) and the inducted leak of 8.16 SCFM (1.0000 wt %/ day). The calculated leak rate of 1.2864 wt %/ day lies within the allowable tolerance band of 1.2286 wt %/ day 1 0.250 wt %/ day. SECTION A - TEST PREPARATIONS A.1 Type A Test Procedure The IPCLRT was performed in accordance with Quad-Cities Procedure QTS 150-6, Rev. 1, including checklist QTS 150-Si through S13 and subsections T2, T3, T6, T8, T9, and T10. Approved Temporary Procedure 1363 and 1364 were written to include the precaution of valving out the H /02 monitoring 2 panel calibration gas cylinders prior to the test and valving the cylinders back in after the test. Approved Temporary Procedure 1365 altered the valve lineup to include the CAM H /02 monitoring system. 2 These procedures were written to conply with 10 CFR 50 Appendix J, ANS/ ANSI N45.4-1972, and Quad-Cities Unit One Technical Specifications, and to reflect the Commission's approval of a short duration test using the BN-TOP-1, Rev. 1 Topical report as a general test method. A.2 Type A Test Instrumentation Table One shows the specifications for the instrumentation utilized in the IPCLRT. Table Two lists the physical locations of the temperature and humidity sensors within the primary containment.

A.2.a. Temperature The location of the 30 platinum RTD's was chosen to avoid conflict with local temperature variations and thermal influence from metal structures. A temperature survey of the containment was conducted prior to the test to verify that the sensor locations were representative of average subvolume conditions. The RTD's were manufactured by Burns Engineering Inc. and are Model SP 1Al-5 1/2-3A. Each RTD and its associated bridge network was calibrated to yield an output of approximately 0-100 mV over a temperature range of 50-150*F. Each RTD was calibrated by comparing the bridge output to the true temperature as indicated by the temperature standard. Three temperatures were used for the calibration. Two calibration constants (a slope and intercept of the regression line) were computed for each RTD by performing a least squares fit of the RTD bridge output to the reference standard's indicated true temperature. The temperature standard used for all calibrations was a Volumetrics RTD Model VMC 701-B used with a Dewcell/RTD Calibrator Model 07782. The standard was calibrated by Volumetrics on January 1, 1986 to standards traceable to the NBS. The plant process computer scanned the output of each RTD-bridge network and converted the output to engineering units using the calibration constants. A.2.b. Pressure Two precision quartz bourdon tube, absolute pressure gauges were utilized to measure total containment pressure. Each gauge had a local digital readout and a Binary Coded Decimal (BCD) output to the process computer. Primary containment pressure was sensed by the pressure gauges in parallel through a 3/8" tygon tube connection to a special one inch pipe penetration to the containment. Each precision pressure gauge was calibrated from 62.6-65.2 PSIA in approximately 0.5 PSI increments using a third precision pressure gauge (Volumetrics Model 07726) that had been sent to Volumetrics for calibration. The pressure standard was calibrated on January 2, 1986 using NBS traceable reference standards. The digital readout of the instruments were in " counts" or arbitrary units. Calibration constants (a slope and intercept of a regression line) were entered into the computer program to convert " counts" into true atmospheric pressure as read by the third, reference gauge. No mechanical calibration of the gauges was performed to bring their digital displays into agreement with true pressure. A.2.c. Vapor Pressure Ten lithium chloride dewcells were used to determine the partial pressure due to water vapor in the containment. The dewcells were calibrated using the Volumetrics calibrator described in section A.2.a. above and a chilled mirror dewcell standard (Volumetrics S/N 1263) calibrated on March 7, 1986 by 0483H Volumetrics'. The calibration constants for each dewcell (the slope and intercept of a regression line) were computed relating the 100 mV output of the signal conditioning carJs to the actual dewpoint indicated by the reference standard. A humidity survey of the conteinment was conducted prior to the test to verify that the sensor locations were representative of average subvolume conditions. A.2.d. Flow A rotameter flowmeter, Fischer-Porter serial number 8508A9252R001, was used for the flow measurement during the induced leakage phase of the IPCLRT. The flowmeter was calibrated by Fischer-Porter to within 31% of full scale (.9-11.-5 SCFM) using NBS traceable standards. Plant personnel continuously monitored the flow during the induced leakage phase and corrected any minor deviations from the induced flow rate of 8.16 SCFM by adjusting a 3/8" needle valve on the flowmeter inlet. The flow meter outlet was unrestricted and vented to the atmosphere. A.3 Type A Test Measurement The IPCLRT was performed utilizing a direct interface with the station process computer. This system consists of a hard-wired installation of temperature, dewpoint, and pressure inputs for the IPCLRT to the process computer. The interface allows the process computer to scan the inputs and send the data, still as a millivolt signal or BCD (binary coded decimal) in the case of pressure, to the PRIME computer with minimal manual inputs and without the disadvantages of multiplexers or positioning sensitive electronic hardware inside the containment during the test. The PRIME computer was used to compute and print the leak rate data using the ANSI /ANS mass plot method and the BN-TOP-1 method. Key parameters, such as total time measured leak rate, volume weighted dry air pressure and temperature, and absolute pressure were plotted on a Ramtek color terminal. Plant personnel also plotted a large number of other parameters, including reactor water level and temperature, dry air mass, volume weighted partial pressures and temperature, total time leak rate, statistically averaged leak rate and UCL, and all sensor outputs in engineering units. In all cases, data was plotted hourly and computer summaries were obtained at 10 minute time intervals. The plotting of data and the computer printed summaries of data l allowed rapid identification of any problems as they might develop. Figure 2 shows a schematic of the data acquisition system.

A.4 Type A Test Pressurization A 3000 SCFM, 600 hp, 4 kV electric oil-free air compressor was used to pressurize the primary containment. An identical compressor was available in standby during the IPCLRT. The compressors were physically located on a single, enclosed truck trailer located outside the Reactor Building. The compressed air was piped using flexible metal hose to the Reactor Building, through an existing four inch fire header penetration, and piped to a temporary spool piece that, when installed, allowed the pressurization of the drywell through the "A" containment spray header. The inboard, containment spray isolation valve, M0-1-1001-26A was open during pressurization. Once the containment was pressurized, the M0-1-1001-26A valve was closed and the spool piece was removed and replaced with c blind flange. l 0483H ; L

SECTION 8 - TEST METHOD B.1 Basic Technique The absolute method of leak rate determination was used. The absolute method uses the-ideal gas laws to calculate the measured leak rate, as defined in ANSI N45.4-1972. The inputs to the measured leak rate calculation include suovolume weighted containment temperature, subvolume weighted vapor pressure, and total absolute air pressure. As required by the Commission in order to perform a short duration test (measured leak rate phase of less then 24 hours), the measured leak rate was statistically analyzed using the principles outlined in BN-TOP-1, Rev. l. A least squares regression line for the measured total time leak rate versus time since the start of the test is calculated after each new data set is scanned. The calculated leak rate at a point in time, t, is the leak rate i on the regression line at the time t. i The use of a regression line in the BN-TOP-1, Rev. I report is different from the way it is used in the ANSI /ANS standards. The latter standard uses the slope of the regression line for dry air mass as a function of time to derive a statistically averaged leak rate. In contrast, BN-TOP-1, Rev. I calculates a regression line for the measured leak late, which is a function of the change in dry air mass. For the ANSI /ANS calculations one would expect to always see a negative slope for the regressica line, because the dry air mass is decreasing over time due to leakage from the containment. For the regression line computed in the BN-TOP-1, Rev.1 method the ideal slope is zero, since you presume that the leakage from the containment is constant over time. Since it is impossible to instantaneously and perfectly measure the containment leakage, the slope of the regression line will be positive or negative depending on the scatter in the' measured leak rate values obtained early in the test. Since the measured leak rate is a total time calculation, the values computed early in the test will scatter much more than the values computed after a few hours of testing. The computer printouts titled " Leak Rate Based on Total Time Calculations" attached to the BN-TCP-1, Rev. I topical report are misleading in that the column titled " Calculated Leak Rate" actually has printed out the regression line values (based on all the measured leak rate data computed from the data sets received up untti the last time listed on the printout). The calculated leak rate as a function of time (tj) can only be calculated from data available up until that point in time, t. This is significant in that the i calculated leak rate may be decreasing over time, despite a substantial positive slope in the last computed regression line. Extrapolation of the regression line is not required by the BN-TOP-1, Rev. I criteria to terminate a short duration test. What is required is that the calculated leak rate be decreasing over time or that an increasing calculated leak rate be extrapolated to 24 hours. The distinction between the regression line values and the calculated leak rate as a function of time is made in Section 6.4 of BN-TOP-1, Rev. l. Calculated leak rates, as a function of time, are correctly printed out in the " Trends Based on Total Time Calculations" computer printouts in Appendix B of BN-TOP-1, Rev. l. 0483H Associated with each calculated leak rate is a statistically derived upper confidence limit. Just as the calculated leak rate in BN-TOP-1, Rev. I and the statistically averaged leak rate in the ANSI /ANS standards are not the same (and do not necessarily yield nearly equal values), the upper confidence limit calculations are greatly different. In the BN-TOP-1, Rev. I topical report the upper confidence limit is defined as the calculated leak rate plus the product of the two sided 97.5% T-distribution value (as opposed to the one-sided 95% T-distribution used in the ANS/ ANSI standard) and the standard deviation of the measured leak rate data about the computed regression line (which has no relationship to the value computed in the ANSI /ANS standards). There are two important conclusions that can be derived from data analyzed using the BN-TOP-1, Rev. 1 method:

1) the upper confidence limit for the same measured leak rate data can be substantially greater than the value calculated using the ANSI /ANS method, and 2) the upper confidence limit does not converge to the calculated leak rate nearly as quickly as usually observed in the latter method as the number of data sets becomes large.

With this in mind, the upper confidence limit can become the critical parameter for concluding a short duration test, even when the measured leak rate seems to be well under the maximum allowable leak rate. A graphical comparison of the two methods can be made by referring to Figure 3 for the BN-TOP-1, Rev. I calculated leak rate and upper confidence limit and to Figure F-1 for the statistically averaged leak rate and upper confidence limit based on ANSI /ANS 56.8-1981. This data supports the contention of many that BN-TOP-1, while it may not give the best estimate of containment leakage, is a conservative method of testing. B.2 Supplemental Verification Test The supplemental verification test superimposes a known leak of approximately the same magnitude as LA (8.16 SCFM or 1.0 wt %/ day as defined in the Technical Specifications). The degree cf detectability of the combined leak rate (containment calculated leak rate plus the superimposed, induced leak rate) provides a basis for resolving any uncertainty associated with the measured leak rate phase of the test. The allowed error band is i 25% of L-A There are no references to the use of upper confidence limits to evaluate the acceptability of the induced leakage phase of the IPCLRT in the ANS/ ANSI standa ' or in BN-TOP-1, Rev. 1. B.3 _ sment Error Analysis An instrument error analysis was performed prior to the test in accordance with BN-TOP-1, Rev. 1 Section 4.5. The instrument system error was calculated in two parts. The first was to determine the system accuracy uncertainty. The second and more important calculation (since the leak rate is impacted most by changes in the containment parameters) was performed to determine the system repeatability uncertainty. The results were 0.0881 wt %/ day and 0.0160 wt %/ day for a 12-hour test, respectively. These values are inversely proportional to the test duration. The instrumentation uncertainty is used only to illustrate the system's ability to measure the required parameters to calculate the primary containment leak rate. The mathematical derivation of the above values can be found in Appendix D. The method of calculating the equipment uncertainty is in conformance with the method outilned in BN-TOP-1. 0483H -. = - - _ _. It is extremely important during a short duration test to quickly identify a failed sensor and in real time back the spurious data out of the calculated volume weighted containment temperature and vapor pressure. Failure to do so can cause the upper confidence limit value to place a short duration test in jeopardy. It has been the stations experience that sensor failures should be removed from all data collected, not just subsequent to the apparent failure, in order to minimize the discontinuity in computed values that are related to the sensor failure (not any real change in containment conditions). For this test, however, no instrument failures were encountered. SECTION C - SEQUENCE OF EVENTS C.1 Test Preparation Chronology The pretest preparation phase and containment inspection was completed on March 21, 1986 with no apparent structural deterioration being observed.

SECTION E - TEST CALCULATIONS Calculations for the IPCLRT are based on the BN-TOP-1, Rev. I test method and are found in Quad Cities procedure tables QTS 150-T3 and T9. A reproduction of these procedures can be found in Appendix C. In preparing for the firs't Quad Cities short duration test using BN-TOP-1, Rev. I a number of editorial errors and ambiguous statements in the topical report were identified. These errors _are presented in Appendix E and are editorial in nature only. The Station has made no attempt to improve or deviate from the methodology outlined in the topical report. Section 2.3 of BN-TOP-1, Rev.1 gives the test duration criteria for a short duration test. By station procedure som? of these duration criteria have been made more conservative and in some cases these changes may be required by regulations. A. " Containment Atmosphere Stabilization ' .Once the containment is at test pressure the containment atmosphere shall be allowed to stabilize for abcut four hours ( 4 hours required by Quad Cities procedure and actual stabilization: 8 hrs) The atmosphere is considered stabilized when: 1. The rate of change of average temperature is less than 1.0*F/ hour averaged over the last two hours. DATA SET

Approximate time interval between data sets is 10 minutes, or 2.

"The rate of change of temperature changes less than 0.5*F/ hour / hour averaged over the last two hours." (Not required if A.1 satisfied) B. Data Recording and Analysis 1. "The Trend Report based on Total Time calculations shall indicate that the magnitude of the calculated leak rate is tending to stabilize at a value less tnan the maximum allowable leak rate (L ) A By Quad Cities procedure the calculated leak rate must be less than 0.75 L. The actual value was 0.2286 L, stable, and A A decreasing (no extrapolation required). i and 0483H - -__

2. "The end of the test upper 95% confidence limit for the calculated leak rate based on total time calculations shall be less than the maximum allowable leak rate." if By Quad Cities procedure the upper confidence limit must be less than 0.75'L. The actual value was 0.2975 L - A A an_d 3. "The mean of the measured leak rates based on Total Time calculations over the last five hours of the test or last 20 data points, whichever provides the most data, shall be less than the maximum allowable leak rate." By Quad Cities procedurs this' average must be less than 0.75 L. The actual value was 0 2372.L.for the last 5 hours. A 7 A afLd 4. " Data shall be recorded at approximately equal intervals and in no case at intervals greater than one hour." At Quad Cities data scans are automatically performed on 10 minute intervals. No. data sets were missed or lost during the 12 hour s test period. No computer failures were encountered. and J 5. "At least twenty (20) data point shall be provided for proper statistical analysis." There were 73 data sets taken for this test. a!Ld 6. "In no case shall the minimum test duration be less than six (6) hours." Quad Cities' procedure limits a short duration test to a minimum of twelve (12) hours. This may be reduced in the future. The data taken during this test would support the argument that a shorter duration test can be conducted. All of the above termination criteria were satisfied in six (6) hours. SECTION F - TYPE A TEST RESULTS F.1 Measured Leak Rate Test Results Based upon the data obtained during the short duration test, the following results were determined: (LA - 1.0 wt %/ day)

1) Calculated leak rate at 12 hours equals 0.2286 wt %/ day and declining steadily over time (<0.7500 wt %/ day).

0483H -

2) Upper confidence limit equals 0.2975 wt %/ day and declining (<0.750 wt

%/ day).

3) Hean of the measured leak rates for the last 5 hours (31 data sets) equals 0.2372 wt %/ day (<0.750 wt 1/ day).

4) batasetswereaccumulatedatapproximately10minutetimeintervals and no intervals exceeded I hours.

5) There were 73 data sets accumulated in 12 hours.

6) The minimum test duration (by procedure) of 12 hours was successfully accomplished (> 12 hours).

F.2 Induced Leakage Test Results A leak rate of 8.16 scfm (1,000 wt %/ day) was induced on the primary containment for this phase of the test. The leak rates during this phase of the test were as follows. Total Time Calculated Leak Rate 0.2286 0.2286 (Measured Leak Rate Phase) Induced Leak (8.16 scfm) 1.0000 1.0000 Allowed Error Band +0.2500 -0.2500 1.4786 0.9786 Calculated Leak Rate 1.2864 wt %/ day The induced phase of the test has a duration criteria given in Section 2.3.C of BN-TOP-1. The test duration requirements are listed below and were satisfied by the test procedure and the data analysis: 1. Containment atmospheric conditions shall be allowed to stabilize for about one hour after superimposing the know leak. (actual: I hour 8 minutes). 2. The verification test duration shall be approximately equal to half the integrated leak rate test duration. (actual: 6 hours for 12 hour test) 3. Results of this verification test shall be acceptable provided the correlation between the verification test data and the integrated leak rate test data demonstrate an agreement within plus or mius 25 percent. (actual: see results above) I i 0483H i F.3 Pre-Operational Results vs Test Results Past IPCLRT reports have compared the results of each test with the pre-operational IPCLRT, performed April 20-21, 1971. Over the last 15 i-years, different test equipment, sensor locations and number of sensors, test. methods, and test duration have been used. This test yleided results 1 that compare favorably with recent tests and demonstrate that there has j been no substantial deterioration in containment integrity.

e e APPENDIX B TEST CORRECTION FOR SUMP LEVEL CHANGES 6 0483H - - - -

The total time measured leak rate, given by equation 3 in QTS 150-T9 (see Appendix C), assumes that the containment free air space is 288,737 ft3 at a water level in the reactor of 35" and that any change in reactor water level is due to a water leakage from the containment changing the free air volume. If the water leakage is from the containment and due to the operation of the shutdown, cooling mode of RHR to maintain reactor water temperature, this leakage would not be representative of accident conditions when shutdown cooling would be isolated. During the stabilization phase of the test considerable effort went into tr ing to reduce the rate of level decline from the 1.18 inches / hour (27.1 ftg/hror3.7GPM) that was experienced during the test. Since the leakage could not be reduced further and level indication for the suppression pool indicated that most of the water leaving the reactor was entering the suppression pool, not leaving the containment, the data input to the computer program was duplicated except for leaving the reactor water level constant at 35". The effect of this alteration was to remove the free air space volume correction from the leak rate calculation. To do so was conservative in that it increased the leak rate value and, if some of the water was leaking from the containment, the actual air leakage was less than the computed value. The calculations ignoring the vessel level change were available during the test and have been used for the reported leakage in this report. The test verification during the induced phase of the test demonstrates the accuracy of this model and the change was completely explained to the NRC inspector witnessing the test. A hand calculation, using a complete water balance, is included in this Appendix to show that the leak rate reported is not significantly affected by a more detailed analysis, including changing subvolume free air space due to water leaking from the reactor vessel to the drywell sumps and suppression pool. To perform a leak rate calculation with a changing containment free air space, the dry air mass for each containment subvolume is calculated using the following equation: Hj - 2.6995 X Pj X Vj (Tj + 459.69) where Pj = dry air pressure in i th subvolume, Vi - free air space in the I th subvolume, and T = average temperature in the i th subvolume. L The total containment dry air mass is given by the sum of the dry air masses for all of the subvolumes. 11 Wt, y Ng i=1 0483H -

r The computed leak rate will be the total time leak rate and is given by: Lt - - 2400 X -t _ w. W H W* where W* - dry air mass of the containment at the start of the test, Wt - dry air mass of the containment at time t, H - duration of the test from start to time t in hours, and Lt - total time leak rate at time t. There are 3 subvolumes to consider in evaluating the effects of water leakage from the vessel: the vessel itself (subvolume 11), the suppression pool (subvolume 10), and the subvolume for the drywell equipment drain sump (DWEDS) and the drywell floor drain sump (DWFDS) (subvolume 9). Any water leaking from the vessel in excess of that added to the sumps and suppression pool will be assumed to have leaked from the containment through the shutdown cooling mode of RHR.

Statistical Leak Rate and Confidence Limit. LINEAR LEAST SQUARES FITTING THE IPCLRT DATA The method of "Least Squares" is a statistical procedure for finding the best fitting regression line for a set of measured data. The criterion for the best fitting line to a set of data points is that the sum of the squares of the deviations of the observed points from the line must be a minimum. When this criterion is met, a unique best fitting line is obtained based on all of the data points in the ILRT. The value of the leak rate based on the regression is called the statistically average leak rate. Since it is assumed that the leak rate is constant during the testing period, a plot of the measured containment dry air mass versus time would ideally yield a straight line with a negative slope (assuming a non-zero leak rate). Obviously, sampling techniques and test conditions are not perfect and consequently the measured values will deviate from the ideal straight line situation. Based on this statistical process, the calculated leak rate is obtained from the equation: H = At + 8 where H = contained dry air mass at time t 0483H.

B = calculated dry air mass at time t - 0 A = calculated leak rate t - test duration The values for the Least Squares fit constants A and B are given by: A = {N

where t = the average time for all data sets R = the average air mass for all data sets The second formulas are used in the process computer program to reduce round-off-error. By definition, leakage out of the containment is considered positive-leakage; therefore, the statistically average leak rate is given by: L5 - (-A) * (2400) (9) B (weight %/ DAY) 0483H STATISTICAL UNCERTAINTIES In crder.to c.11culate the 95% confidence limits of the statistically average leak rate, the standard deviation of the least squares slope and the student's T-Distribution function are used as follows.

When performing these calculations on the process computer, E(Hj)2 and (IWj)2 become so large that they overflow. To avoid this problem aWi is substituted for W. 4W1 is the difference 1 between Hj and WBASE-The single sided T-Distribution with 2 degrees of freedom is approximated by the folicwing formula from NBS Handbook 91: T.E. - 1.646698 + 1.455393 + 1.975971 (N-2) (N-2)4 The upper confidence limit (UCL) is given by UCL = ls + o * (TE) 2400 B (weight %/ DAY) (10) 0483H.

CALCULATIONS PERFORMED FOR IPCIJt? DATA FOR TEST DURATION LESS TRAN 24 HOURS Data collected from pressure sensors, dew cells, and RTD's located in the contain===t are processed using the following equations. Some data needs to be analyzed using equations in QTS 150-T3 prior to using these equations. Those equations are referenced by equation number. The primary reference for these calculations is the Topical Report BK-TOP-1 Revision 1. A. MEASURED LEAE RATPi (Total Time) From BN-TOP-1 Rev. 1, Section 4.5 the following equation is given for the measured leak rate using the total time procedure: i = 2400, f,T E\\ o i M g (3) 9,) t T g g th where Ng = measured leak rate in weight % per day for the i data point assuming r), R, and V are constant in the Ideal Gas Law equations;,, time since the beginning of the test period to the i tg = data point in hours; T,, Tg = mean, volume weighted containment temperature at the beginning of the test and at the data point i in 'R (Reference EQ. 3 in QTS 150-T3 and convert to *R (*F + 459.69 = 'R) ). F,, e = calculated dry air pressure in PSIA at the beginning of g i the test and at the data point i (Reference EQ. 5 in QTS 150-T3). Using the following relationship derived in ANSI N45.4-1972 Appendix B given below: W W T P i, o i o-g, (2) o i o where W, Wg = dry air mass of the containment at the beginning of the test and data point i, respectively. 4,

And substituting in the calculation of the containment dry air mass that corrects for a change in reactor water level given in QTS 150-T3 EQ. 6 gives the following expression for the measured leakage: i

CALCULATED LEAK RATE The method of Least. Squa.res is a statistical procedure for finding the "best fit" straight line, commonly called the regression line, for a set of measured data such that the sum of the squares of the deviations of each measured data point from tle straight line is minimized. To determine the calculated lets (L,) rate at time t, the regression line g is determined using the measured leak rate data from the start of the test to time t The calculated leak rate is the point on this line at g. time t. g Lg=Ag+Bg g (4) t where tg = data point; time in hours since the beginning of the test to the i aIt M (I t ) (I M ) 1 g g 1 i* n I (t )3 - (It )3 t g 2 (IM ) (Itt ) _ (yg ) (ze g ) g Ag= ,ygz, (7g )z a I=I i=1 a = number of data sets to time tg C.

The following assumptions are made: A A Pj = E = P where P is the average dry air pressure of the N containment (PSIA) during the test; A A Tj - TN=T where T is the average volume weighted primary containment air temperature (*R) during the test; Pj - PN where P is the total containment atmospheric pressure (PSIA); Pyj = PVN Where Py is the partial pressure of water vapor in the primary containment. l 0483H.

In measuring containment temperature; eg - the error in the measured leak rate; H = duration of the test. NOTE Subvolume #11, the free air space above the water in the reactor vessel, is treated separately from the rest of the containment volume. The reason for the separate treatment is that neither the air temperature or the partial pressure of water vapor is measured directly. The temperature of the air space is assumed to be the temperature of the reactor water, as measured in the shutdown cooling or clean-up demineralizer piping before the heat exchangers. The partial pressure of water vapor is computed assuming saturation conditions at the temperature of the water. Volume weighting the errors for the two volumes (Subvolume #11 and Subvolumes #1-10) is the method used. 0483H _

O APPENDIX E BN-TOP-1, REV. 1 ERRATA The Commission has approved short duration testing for the IPCLRT provided the Station uses the general test method outlined in the BN-TOP-1, Rev. I topical report. The primary difference between that method and the ones previously used is in the statistical analysis of the sessured leak rate data. Without making any judgments concerning the validity of this test method, certain errors in the editing of the mathematical expressions were discovered. The intent here is not to change the test method, but rather to clarify the method in a mathematically precise manner that allows its implementation. The errors are listed below. EQUATION 3A, SECTION 6.2 Reads: L. = A + B t. 1 1 Should Read: Lg=Ag+Bg g t Reason: The calculated leak rate (L ) at time t is computed g using the regression line constants A,g The summation signs la(equation 6 are B. computed using g equations 6 and 7). n defined as I = I, where n is the number of data sets up until i=1 time t.. The regression line constants change each time a new daka set is received. The calculated leak rate is not a linear function of time. PARAGRAPH FOLLOWING EQ. 3A, SECTION 6.2 Reads: The deviation of the measured leak rate (M) from the calculated leak rate (L) is shown graphically on Figure A.1 in Appendix A and is expressed as: Deviation = M -L g g Should Read: The deviation of the measured leak rate (M.) from the regression line (N ) is shown graphically on Figure A.1 in Appendix A and is g expressed as: Deviation x M -N g g where N. = A +B

Reason: The calculated leak rate as a function of time during the test is based on a regression line. The regression line constants, A and B, are g g changing as each additional data set is received. Equation 3A is used later in the test to compute the upper confidence limit as a function of time. For the purpose of this calculation, it is the deviation from the last computed regression line at time t that is.important.
