INTRODUCTION This report presents details of the' Primary Containment Integrated Leak Rate Test (PCILRT) successfully performed on June 3, 1990 at LaSalle County _ Nuclear Power Station, Unit Two.

The test was performed in accordance with 10CFR50,

~

Appendix J and the LaSalle County Unit 7Vo Technical Specifications.

LaSalle County Station is a BWR 5, Mark II containment, located in.Marsellies, 1111 nolo.

LaSalle Unit Two received its operating license in June,;1984.-

A short duration test (6.167 hours0.00193 days 0.0464 hours 2.761243e-4 weeks 6.35435e-5 months ) was conducted using the general test' method outlined in'BN-TOP-1,' Revision 1 (Bechtel Corporation Topical Report)-

dated November 1, 1972.

The total primary containment' integrated leakage' rate was found to be 0.2310 wt%/ day at a test pressure of 41.0 psig, which is within the 0.476'wt%/ day-y acceptance-criterion. lThis value"is the sum of-the calculated leakage rate of O.1541 wt%/ day plus the leakage rate of alljnon-vented penetrations which-16 1

0.0769 wt%/ day The total 95% upper-confidence limit-leakage rate was found i

to be 0.4273 wt%/ day. -This value is the sum'of the. measured 95% upper.

confidence limit of 0.3504-wt%/ day plus the.leakege rate of all non-vented-h penetrations which is 0.0769 wt%/ day.

j The total "As Found" containment leakage rate.was found to be indeterminate.

The Induced phase leakage test result was found to'be 0~7198'wt%/ day. Thisi l

value should. compare with the sum of the measured leak rate phase of 0.1541.

wt%/ day and the induced leakage rate of. 0.6440 wt%/ day '(383.0: SCFH), -the sum of which being within the 1 0.159 wt%/ day (0.25 La) tolerance band.- The l

actual test data results'show a difference of 0.0783 wt%/ day which is within the acceptance criterion.

The schedule for the next integrated primary containment leak; rate-test:is to

The PCILRT was performed in accordance uith Procedure LTS-300-4, Revision 15,: dated March 19, 1990.

This procedure was~ written to:

-comply with 10CFR50 Appendix J, ANSI N45.4 1972, and LaSalle. County-Unit Two Technical Specifications, and to reflect the Nuclear-l Regulatory Commission's, approval of a.short duration test using the BN-TOP-1, Rev. 1 Topical Report as a test method.

Table One shows_the specifications for the 1nstrumentation used in the PCILRT..TabJe.Two lists the physical locations of the temperature'and humidity sensors within;the primary containment.

j a.

Inmperaturn i

Sensors were-suspended to prevent direct thermal influences from any-metal surfaces.

Sensors-were'also kept?away from anyydirect-air flows.

Each thermister was calibrated to yield an-output of -99 mV to

'[

+99 mV over the range of 50*F; to 140*F. : ' Calibrations were done by Commonwealth Edison company, Operational Analysis Dept.

b.

Ernsants Two precision PPM-1000 pressure transmitters were1 utilized.

l Each' transmitter had a local digitalireadoutiin addition to a Binary Coded Decimal output to the process computer.. Primary containment-pressure was sensed by:the pressure transmitters in parallel through-a 3/8" tube connected to a primary-Containmenti pressure sensing instrument line.

Each precision pressure transmitter-was' calibrated over the-1 range O psia to 100 psia in approximately 5 pslajincrements.

l using a Volumetrics Inc. VMC 836 calibration standard.

.c.

Vapor Pressure Ten Lithium Chloride Dewpoint Temperature Units were_ installed throughout the DrywellLand Suppression Pool. The dewpoint cells were placed in locations where the chance of the dewcell becoming damaged was1 slight.

A calibration'was done on each deweell network over theorange of dewpoint temperatures of 34'C'to 100'C. ' Calibrations were 1

performed by Commonwealth Edison Company, Operational. Analysis-Dept.

A.3 Iype A Test' Measurement-The PCILRT was performed utilizing an interf ace with the:Volumetrics Data Acquisition System (DAS) and. Prime Computer.

Information from R

the thermisters.and deweells-is sent to a' Dual MultiplexerLScanneriinL j

the_Drywell. The Scanner takes the-data and sends it through an electrical penetration (E-20) to a SystemLConsole. -The System Console takes' the raw data and converts it' into data readable to a '

computer and'the test engineer. This information is then sent to the-Prime Computer:where'all.needed calculntions are performed and a hard-copy of the;information isLproduced.

A.4 Iype'A Test PressurizAtio.D

.Two. CECO _3000+SCFM, 600 HP diesel: air compressors 1were used to.

pressurize the primary containment.

The compressors were physica11yLlocated:outside the reactor-building. The compressed air was-piped into the reactor building through an existing PCILRT PressurizingLLine.

For. ease:of handling,:

a flexible 4' inch pipe'was used outside:of the reactor building.-

Li The drywell was. pressurized _through the "A" containment spray. header' l

15 inch flange.with an inboard valvo 2E12-F017Ah open'during the' i

PCge 9 SECTION B - TEST METilOD 1

B.1 llasic Techn12Rt The absolute method of' leak rate determinution 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-subvolume weighted containment temperature, subvolume weighted-vapor pressure, and total absolute air pressure.

As required by the Nuclear. Regulatory Commission, in order to perform a-short duration test (measured leak rate phase of less-than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ),-the

_j measured leak rate was statistically analyzed using the principles outlined in BN-TOP-1, Rev. 1.

A least squares' regression line for the measured total time l

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 i

leak rate on the regression line at the time tg.

l D.2 Supplemental Verifign. tion Test-The supplemental verification test superimposes-a known leak of approximately_the same magnitude as La (La =.385.7 SCTH or_0.6350 wt%/ day as-defined in the Technical Specificatons).

The. degree of 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'1 0.25 La.(0.159) wt%/ day.

There are no references to the use of upper. confidence limits to evaluate; the acceptability of the induced leakage phase of the PCILRT in the ANS/ ANSI-standards or in BN-TOP-1, Rev. 1.

\\

D.3 Instrumentation Error Analysig An instrumentation error analysis was performed prior to the _tiest-in accordance with DN-TOP-1, Rev 1 Section 4.5.. The-__ instrument' system error was.

calculated in two parts. The first part was to determine system accuracy uncertainty. The second and more importanE calculation (since the leak' rate

-i is impacted most.by changes in the containment param'eters) was: performed-to

'{

determine the system repeatability uncertainty.

The maximum system error analysis performed prior to a 6-hour test yielded a total: instrument uncertainty of 1 0.0120 wt%/ day.

t The instrumentation uncertainty is used only to illustrate the. system's

'?

ability to measure the required parameters.to calculate the primary-containment leak rate' ItLis 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

~

j can cause the upper confidence'11mit value to place a short duration test in-jeopardy.

It has been station 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 computer values that are related to

.i the sensor failure (not any real change in' containment conditions)'.

F.4 Change in Drywell Sump Letg}

Changes in drywell sump levels were not used in calculating the final' leakage rate. The observed sump level increase during the test resulted 3

in a net volume change of 2.9 Ft.

This represents approximately 7.14*10~4 of the total containment volume.

All inputs to the sumps were in all. probability made through a leakage path directly from the Reactor vessel.

There were no known inputs made from outside the containment throughout the test.

The observed increase i

in sump level therefore, is considered to have negligible effects on the overall-measured leakage rate.

L The method of Least Squares is a statistical procedure for finding the "best fit" straight line, commonly b iled the regression line, for a set of measured data such that the sum of tie aquares of the deviations of each measured data point f rom the straig'et line is minimized.

To determine the calculated leak tate (L ) at time tg, the regression line 1

is determined using the measureG 1eak rate data from the start of the test to time t. The calculated bak rate is the point on this line at time t.

Confidence Limits P

Even though the regression line is statistically determined to minimize j

the sum of the squares of the error, the values of the calculated leak rate cannot be considered to be exactly correct.

If the containment integrated leak rate test were run a number of times, under the same conditions, the calculated leak rates would be close in value but not exactly the same each time.

However, based on statistics we can establjsh confidence limits associated

[

with the regression line cuch that the limits of the calculated leak rate computed would suseessiv11y enclose the true value of the desired parameter a large f raction of the time.

This fraction is called the confidence coefficient and the interval within the confidence limits 1s-the confidence interval.

Confidence limits for the it',egrated leak test computer program are determined based on a confidence coefficient of 95%.

This means that the i

probability that the value of the calculated leak rate will fall within the upper and lower confidence limits, or confidence ins,..

T1, is 95%.

APPENDIK C (CONTINUED) 4 BN-TOP-1 METHOD TEST CALCULATIONS To determine the value of the confidence limits the:following statistical information is required the variance, standard deviation, and the Student's T-distribution.

The variance, as the name implies, is a measure of the variability of individually measured data points from the mean, or in this case, from the regression line.

The variance of the measured leak' rate (M1)'from the calculated leak rate (L1) is given by 2

s

, ggg

-[7) n-2 Where s is the variance and s is the standard deviation based on (n-2) degrees of freedom.

SSO is the sum of the squares of the deviations from the regresssion line and is mathematically expressed below SSO = E (Mi - Ni)2 (8)

Where N3 = deviation from regression line The standard deviation has more practical significance since computing the standard deviation returns the measure of variability to the original-units of measurement. Additionally, it can be shown that given a normal distribution of measurements, approximately 95% of the measurements will' fall within two standard deviations of the mean.-

The number of standard deviations either side of.the regression line which establish a upper confidence interval are more accurately determined using a statistical table called a " Table of Percentage Points.of the T-distribution" and provide increased confidcence in outcomes for small and large sample sizes.

Since we are interested in reporting a single value of calculated leak rate based on measurements taken over a specific. time period, an additional factor is applied to the formula for computing the variance and hence, the standard deviation.

Data Rejection Criteria i

1.

If a sensor, in the opinion of the 7.ech Staf f Engineer, is out of J

range, it will be ignored (i.e., set =0) and the number of operable RTD'a/Thermisters or Dewcells in the subvolumt will be reduced by j

one..The sensor should be considered out of range if it is evident that the sensor has malfunctioned. All rejected data should be maintained if possible and the reason for rejection documented on i

Attachment Z data sheet and in the Events log, (Attachment C).

Should the number of RTD's/Thermisters or the number of Dew cells in

)

a subvolume become equal to zero (accept for Subvolume, 2 and 7:

Zero dowcells already) then.with approval of the Technical Staff, i

Supervisor, substitute the average temperature of the rappropriate subvolume which is chosen based upon the temperature survey and/or:

temperature distribution prior to instrument failure. Document on i

Attachment Z data sheet and in Events bog, (Attachment C).

HQIE i

If all RTD's/Thermisters in subvolume 9 are lost, then stop the test and repair the RTD's/Thermisters or if the AIR in Subvolume 9 can be shown to be near saturation, use Subvolume 9 average Devsell temperature.

If all Dewcells in'Subvolume 9 are lost, and the kir.In Subvolume 9 I

can be shown to be near saturation, use Subvo1Wne 9 s<verage RTD/Thermister temperature.

Also, if the average RTD/Thermister temperature over the last 6 data sets is within 0-%'T of a specific RTD/Thermister, the specific RTD/Thermister-may be chosen as'the Dewcell.

2.

If one pressure transmitter is out of the range of 14 < P (psia) '< 60 the pressure transmitter will be ignored (set =0).

ETEL All Data should be recalculated with bad element (s) deleted.

3.

Raw temperature, pressure, and dew point data should not be. rejected l-statistically, but may be rejected and not used in~the final calculations provided there is a good physical reason ror the rejection.

Datt. ejected, including the cause or probable cause for the bad data, are to be documented.

If the validity of certain data is suspect, but no physical reason is found, then a statistical.

j rejsselon technique may be applied.

(See ANSI /ANS 56.8-1987, for l

Data Rejection Criterion).

A. data point may be rejected'if it is expected to ocr.ur statistically less than 5% of the time..The statistical rejection of more than 5% of a set of data should not be allowed.
