INTRODUCTION This report presents the test method and results of the Integrated Primary Containment Leak Rate Test (IPCLRT) successfully performed on December 16-17, 1982 at Quad-Cities Nuclear Power Station, Unit One. The test was performed in accordance with 10 CFR 50, Appendix J, and the Quad-Cities Unit One Technical Specifications.

For the first time at Quad-Cities a short duration test (less than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ) was conducted usin2 the general test method outlined in BN-TOP-1, Revision 1 (Bechtel Corporation Topical Report) dated November 1,1972.

Using the above test method, the total primary containment integrated leak rate, adjusted to include penetrations not tested during the IPCLRT, was calculated to be 0.524 wt %/ day at a test pressure greater than 48 PSIG. The calculated leak rate was within the 0.750 wt %/ day acceptance criteria (75% of L ).

A The associated upper 95% confidence limit was 0.731 wt %/ day.

Excluding non-testable penetrations,.the supplemental induced leakage test result was calculated to be 1.326 wt %/ day. This value should compare with the sum of the measured leak rate phase result (0.453 wt %/ day) and the induced leak of 8 SCFM (0.980 wt %/ day). The calculated leak rate of 1.326 wt %/ day lies within the allowable tolerance band of 1.433 wt %/ day i 0.250 wt %/ day.

i SECTION A - TEST PREPARATIONS J A.1 Type A Test Procedure.

The IPCLRT was performed in accordance with Quad-Cities Procedure QTS 150-6, Rev. 1, including checklists QTS ISO-SI through S13 and subsections T2, T3,-

T6, T8, T9, and T10. Approved Temporary Procedure 1748 was written for the proper operation of the. IPCLRT air compressor and the. method for pressurizing .

the containment volume. Temporary ' Procedure 1757 slightly modified the instrument

~

location of four test instruments without changing subvolume locations.

Temporary Procedure 1756 modified the pre-test valve line-up to reflect valves that had been removed (with lines capped) since the last IPCLRT and' valves that were not locked in their position and needed no locks. Temporary Procedure 1758 modified the post test valve line-up to bring it in agreement with the start up preparations for the Unit that were in progress following the IPCLRT.

These procedures were written to comply with 10 CFR 50, Appendix-J, ANS/ ANSI i N45.5-1972, Quad-Cities Unit One Technical Specifications, and to. reflect the l Commission's approval of a short duration test using the BN-TOP-1, Rev. 1 Topical report as a general test method.

A.2.a. Temperature The location of the 30 platinum RTD's was chosen to avoid conflict with local temperature variations and thermal influeuce from metal structures.

The RTD's were manufactured by Burns Engineering Inc. and are Model

'SP 1Al-5\-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 cotput 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 07731. The standard was calibrated by Volumetrics on November 11, 1982 to standards traceable to-the NBS.

The plant process computer scanned the output of each RTD-bridge network I

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 50-70 PSIA in 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 October 22, 1982 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 l The eight lithium chloride dewcells were physically situated in the contain-ment based on the results of the last four IPCLRT's performed at Quad-Cities and remained unchanged from the last IPCLRT performed for Unit One in February, 1979. The dewcells used were supplied by Volumetrics and manufactured by Foxboro.

i I

The calibration constants (the slope and intercept of a regression line) for each dewcell were computed relating the 0-150 mV output of the sensor conditioning card to the actual dewpoint indicated by a reference standard.

A three point calibration was performed for each dewcell. The reference standard was a chilled mirror dewcell standard, Volumetrics Model VMC 305, used with the Dewcell/RTD Calibrator Model 07731. The reference standard was calibrated by Volumetrics on October 22, 1982 using NBS traceable standards.

A.2.d. Flow A rotameter flowmeter, Fischer-Porter serial number 8209A9118RIA, was used for the flow measurement during the induced leakage phase.of the IPCLRT. The flowmeter was calibrated on October 20, 1982 by Fischer-Porter to within 11%

of full scale ( 8-8.44 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 SCFM by adjusting a 3/8" needle valve on the. flowmeter inlet.

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, calculate, and print results with minimal manual input. The process computer output gave measured and calculated leak rate data using the dry air mass method given in i ANS/ ANSI 56.8-1981. This output was used for comparison purposes only.

Data sets giving instrument outputs were automatically transferred to a Prime 750 computer where the containment data was used to compute the leak rates and confidence limits based on BN-TOP-1, Rev. 1. A Ramtek color terminal was used to aid in monitoring the containment environmental configuration and instrument stability. The BN-TOP-1, Rev. I calculations were also' displayed in summary form showing the results and trends as each additional data. set was received. Key parameters such as containment volume weighted dry air pressure and temperature and calculated leak rates with upper confidence limits were plotted and displayed on the computer terminal.

l During the IPCLRT plant personnel plotted a number of subvolume, containment, and calculated parameters in order to quickly identify any problems that might develop during the test such as a failed sensor or unusual leak rate data that might indicate excessive leakage.

Figure 2 shows a schematic diagram of the IPCLRT 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 Etactor 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 MO 1-1001-26A valve was closed and the spool piece was removed and replaced with a blind flange.

Il0V PR1i1E 3:1-TOP-1 C0ftPUTER liETHOD FIGURE 2 SECTION B - 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 ANS/ ANSI N45.4-1972. The inputs to.the measured. leak rate calculation include subvolume weighted containment temperature, subvolume weighted vapor pressure, total air pressure, and a total containment volume correction for reactor water level.

As required by the Commission in order to perform 4 short duration' test (measured leak rate phase of 12-24 hours), the measured lea's rite was-strtisti-cally analyzed using the principles outlined in BN-TOP-1, Rev. 1. A least squares regression line for measured leak rate versus time since the startiof the test is calculated af ter each new data set is scanned. The calculated leak rate at a point in time, t i, is the leak rate on the regression line at the time t g.

The use of a regression line in the BN-TOP-1, Rev. I report is different from the way it is used in the ANS/ ANSI 56.8-1981 standard. 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.~1 calculates a regression line for the measured leak late, which is function of the change in dry air mass. For the ANS/ ANSI calculations one would expect to-always see a negative slope for the regression 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. I 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-TOP-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 until the last time listed on the printout). The calculated leak rate as a function of time (t y ) can only be calculated from data,available up until that point in time, t.. This is significant in that the 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 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

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. 1.

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. 1.

! Associated with each calculated leak rate is a statistically derived upper confidence limit. Just as the calculated leak rate in BN-TOP-1, Rev.-1 and the statistically averaged leak rate in the ANS/ ANSI standard -are not the same (and do not evenl yield nearly equal values), the upper confidence limit calcula-tions 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 ANS/ ANSI standard).

There are two important conclusions that can be derived from data analyzed using the BN-TOP-1, Rev. I method: ~1) the upper coafidence limit for the same measured leak rate data can be substantially greater than the value calculated 4 using the ANS/ ANSI 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 i 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. 1 calculated leak rate and upper confidence limit and to Figure 13 for the statistically averaged .

leak rate and upper confidence limit based on ANS/ ANSI 56.8-1981.

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 wt %/ day as defined in the Technical j

Specifications). The degree of detectability of the combined leak rate (contain-ment 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 l

, the acceptablility of the induced leakage phase of the IPCLRT in the ANS/ ANSI standards or in BN-TOP-1, Rev. 1.

l L B.3 Instrument Error Analysis l

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 j system repeatability uncertainty. The results were 0.0890 wt %/ day and t

0.0175 wt %/ day for a 12-hour test, respectively. -These values are inversely proportional to the test duration.

After pressurizing the containment and at various stages of the test two i

RTD's and one dewcell failed giving unreasonable indications. The two RTD's j were deleted from the subvolume average temperature calculations from the point where they deviated from their past pattern and the values indicated by.

other RTD's in the same subvolume. The deweell, though somewhat erratic in its output, was included in the measured leak rate phase until it failed completely 11 hours1.273148e-4 days 0.00306 hours 1.818783e-5 weeks 4.1855e-6 months into the test.

Removing the three instruments that failed during the test gives a system accuracy uncertainty of .0911 wt %/ day and a system repeatability uncertainty of .0184 wt %/ day for a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months test.

The instrumentation uncertainty is used only to illustrate the system's ability to measure the required rarameters to calculate the primary containment leak rate. The mathematical derivation of the above volues can be found in Appendix D. The instrumentation uncertainty is always present in the data and is incorporated in the 95% upper confidence limit.

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.

SECTION C - SEQUENCE OF EVENTS C.1 Test Preparation Chronology The. pretest preparation phase and containment inspection was completed on December 16, 1982 with no apparent structural deterioration being observed.

Major preliminary steps included:

1) Completion of all Type B and C tests, component repairs, and retests except for the main steam line drain valve MO 1-220-1. The IPCLRT was conducted, with Commission approval, with this valve closed. The HO 1-220-2 valve, in line with the above valve, minimized leakage-through this flow path during the IPCLRT.

2) Blocking open three pairs of drywell to suppression chamber vacuum breakers.

3) Installation of all IPCLRT test equipment in the suppression chamber.

4) Completion of all <--s4rs and installations in the drywell.

5) Venting of the is . vessel to the drywell by opening the manual head vent line t o the drywell equipment drain sump.

6) Completion of the.IPCLRT data acquisition system including computer programs , instrument console, locating instruments .:ba the drywell, and associated wiring.

7) Re-established water level in the suppression chamber following a seismic piping change to the level instrument sensing lines.

8) Completion of the pre-test valve line-up.

1008 dinor leaks observed in 7IP room. Packing leaks on isolation valves. Total approximate 4 scfh.

Reduced to minute value after tightening packings.

1045 A0 1-8801C had small packing leaks (48 scfh).

Repaired.

1130 Torus water temperature is 58 F. Containment will probably be cooling off during the test due to the above. Containment temperature dropping at 0.33 F/hr.

1330 Containment temperature dropping in the last hour at a rate of 0.55 F/hr.

C.3 Measured Leak Rate Phase Chronology DATE TIME EVENT 12-16-82 1330 Containment temperature stable to misch less than 1*F/hr.

1 1342 Started Measured Leak Rate Phase with RTD 18 removed from the instrument scan.

1805 Observed erratic readings from Dew Cell #1. Dew point temperature changed 22*F in 10 minutes. On the next scan it went back to an intermediate value.

Instrument continued to act erratic, but was not removed from thc scan.

12-17-82 0112 Dew Cell #1 for subvolumes 1 and 2 failed. Computer rejected input automatically for giving an unreason-

! able output. Program assigns partial _ pressure of water vapor from the-nearest.deweell to subvolumes I and 2. Measured leak rate dropped 0.065 wt %/ day.

and stayed steady when Dev Cell #1 was removed from the scan.

Radiation Protection is collecting a sample.

0223 Radiation Protection Department completed sample analysis.

0302 One hour stabilization is complete. Re-initialized program for new base data set.

0325 Failed RTD #23. Changed output by approximately 25*F in one data set. Unreasonable temperature compared to all other temperatures in the drywell.

Three other RTD's in that subvolume. Re-initialized i

base data set with RTD #23 removed from scan.

0332 Scan completed for base data set for the Induced Phase.

0412 Dewcell~#1 reappeared in the scan. Failed Dewcell

1 because its sudden reappearance.in the scan shows erratic unreliable output. Will remove the sensor data manually from computer for the three ,

data sets it re-appeared.

0435 Process computer down. No scans.

0515 Computer back up. Beginning scan without Dewcell #1.

SECTION E - TEST CALCULATIONS Calculaticns for the IPCLRT using the BN-TCP-1, Rev. I test method are found in Quad-Cities procedures QTS 150-T3 and T9. A reproduction of these procedures can be found in Appendix C. In the course of preparing for the IPCLRT a number of errors were identified in the published version of BN-TOP-1, Rev. 1. These errors were editorial in nature and no attempt was made by Station personnel to deviate from the intended procedure outlined in the BN-TOP-1, Rev. I topical report. These errors are identified in Appendix E.
A block diagram of the computer program to perform the calculations based on the BN-TOP-1, Rev. I test method can be found in Appendix G.

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 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months equals 0.453 wt %/ day and declining steadily over time (<0.750 wt %/ day).
2) Upper confidence limit equals 0.660 wt %/ day and declining
(<0.750 wt %/ day).
3) Mean of the measured leak rates for the last 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months (30 data sets) a equals 0.377 wt %/ day (<0.750 wt %/ day).
4) Data sets were accumulated st approximately 10 minute time intervals and no intervals exceeded I hour.
5) There were 73 data sets accumulated in 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .
6) The minimum test duration of 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months was successfully accomplished
(> 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months ).
F.2 Induced Leakage Test Results A leak rate of 8.0 scfm (0.980 wt %/ day) was induced on the primary containment for this phase of the test. The leak rates during this phase of the test were ds follows.
Total Time Calculated Leak Rate 0.453 0.453 (Measured Leak Rnte Phase)
Induced Leak (8.0 scfm) 0.980 0.980 Allowed Feror Band + 0.250 -

l F.3 Leak Rate Compenaation For Non-Vented Penetrations The IPCLRT was performed with the following penetrations not drained and a vented as required by 10 CFR 50, Appendix J. The "as left" leak rates for
each of these penetrations, as determined by Type C testing, is also listed

, TOTAL 34.81 0.0711 This yields the following adjusted leak rates:
I Calculated Leak Rate (BN-TOP-1, Rev. 1). .524 wt %/ day Upper Confidence Limit (BN-TOP-1, Rev. 1) .731 wt %/ day i
For the purposes of comparison, using the ANS/ ANSI method the following are the adjusted leak rates:
Statistically Averaged' Leak Rate .376 wt %/ day Upper Confidence Limit (ANS/ ANSI 56.8) .465 wt %/ day _
It is understood that the leak rates associated with the ANS/ ANSI calculations can only be reported if a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months test is performed.
F.4 Pre-Operational Results vs. Test Results Past IPCLRT reports have compared t e results of those tests with the pre-operational IPCLRT, performed April 20-21, 1971. The last IPCLRT on Unit One conducted February 19-22, 1979 yielded a statistically averaged leak rate (ANS/ ANSI method) of 0.3175 wt %/ day after' correcting for non-tested penetrations.
I The present test, if the same method of data analysis were used, except for the test duration, gave a leak rate of 0.376 wt %/ day. The difference between the results are within each tests uncertainty limits.
The reported leak rate using the BN-TOP-1 Rev. I method of calculating a leak rate for a short duration test will show a significant increase over past
, IPCLRT results. The increase is due almost entirely to the difference in method of computation, rather than an increase in containment leakage.

APPENDIX A TYPE B AND C TESTS Presented herein are the results of local leak rate tests conducted on all penetrations, double-gasketed seals, and isolation valves since the previous IPCLRT in February, 1979. All valves with leakage in excess of the individual valve leakage limit were restored to an acceptable leak tightness prior to the resumption of power operation with the exception of the Main Steam Line Drain Valve, MO 1-220-1. Technical Specification change to T.S. 3.7 A.2.a.2. was approved by the Commission to allow operation withest first repairing this valve. Total leakage for double gasketed seals and total leakage for all other penetrations and isolation valves following repairs satisfied the Technical Specification limits. These results are listed in Table A-1.

The total as found leakage for isolation valves was 2143.76 SCFH plus an unknown value for the "A" feedwater line.
The total as found leakage for double gasketed seals was 7.5 SCFH plus an unknown value for the drywell head seal.
i Based on the above, the total as found leak rate of the primary containment wan greater than the Technical Specification criteria of I wt%/ day.
If only the leakage' paths tested during the IPCLRT, plus an adjustment for all penetrations not tested during the IPCLRT, are considered, then the containment leak rate is calculated to be 0.524 wt%/ day and falls within the Technical 1 Specification acceptance criteria of 0.750 wt%/ day.

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 devi&tions 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 af 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:

The following assumptions are made: l l _ A A P where P is the average dry air pressure of the containment g =P_3=P (PSIA) during the test; A A T1=T3=T where T is the average volume weighted primary containment air temperature ('R) during the test; Pg =P N where P is the total containment atmospheric pressure (PSIA); Pyg = PVN *** is the partial pressure of water vapor in the primary V containment. j FOR REFERECE 0! t 1 l l
QTS 150-T10 Revision 1 Taking the partial derivative in terms of pressure and temperature of equation (I and substituting in the above assumptions yields the following equation found in Section 4.5 of BN-TOP-1 Rev. 1: e g=1 0*2( )2+2( )2 (2) P T where ep = the error in the total pressure measurement system, e = t ( (*p ) + ( Py)2 } ; p T p = (instrument accuracy error) / J no. of inst. in measuring T total containment pressure; py = (instrument accuracy error) / J no. of inst. in measuring vapor partial pressure; e T = (instrument accuracy error) / / no. of inst. in measuring containment temperature; e 3 = the error in the measured leak rate; 7 H = duration of the test. .

___ u NOTE t Subvolume #11, the free air space above the water in the reactor vessel, is treated separately from t.ae 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 desineralizer piping before the heat l exchangers. The partial pressure of water vapor is computed assuming saturation conditions at l the temperature of the water. Volume weighting i the errors for the two volumes (Subvolume #11 and Subvolumes #1-10) is the method used. QTS 150-T10 Revision 1 B.

I topical report. The primary difference between that method and the ones previously used is in the statistical analysis of the measured 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: Lg=A+Btg o Should Read: L = A. + B. t. i i i i Reason: The calculated leak rate (Lg ) at time t is computed using the regression line constants A ,gBgg (computed using equations 6 and 7). The summation signs in equation 6 are 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 newdaba. set is receivsd. 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 g -L g Shou'd Read: The deviation of the measured leak rate (M g) from the regression line (N )g is shown graphically on Figure A.1 in Appendix A and is expressed as: Deviation = M g -N g where N. 1

Reason: The calculated leak rate as a' function of time during the test is based on a regression line. The regression line constaats, Ag and B g, are changing as each additional data set is received. Equation 3A is used later in the test to compute the upper ccafidence limit as a function of time.
-For the yarpose of this calculation, it is the deviation from the last computed regression line at time t that is important.
