II. TYPE A TEST METHODS AND TEST RESULTS The containment leakage rate was determined by utilizing the Absolute Analysis Method and the Mass Plot Calculational Technique.- Changes in the water level of the reactor vessel were computed and included in each data set collection. At the conclusion of the test, the results of the Absolute and Mass Plot Methods were corrected to account for changes in the containment net-free air space due to water accumulation in the drywell sump. These results were further adjusted to incorporate the results of Type B and Type C Local Leak Rate Testing (LLRT). The level corrected leakage rates and the LLRT adjusted leakage rates are given below.

LEVEL CORRECTION CALCULATION The UCL-95 calculated leakage rate was corrected to account for water accumulation into the containment sump as determined by the following equation:

L' - L + (24)(0.1338)(Fi - Fn ) (100)

(302,400)aT where, L - UCL -95 calculated leakage rate in %wt./ day 24 - 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> / day -

0.1338 - conversion factor for converting gallons to cubic feet Fi - final sump integrator. reading in gallons F. - initial sump integrator reading in gallons 100 - 100%

302,400 - containment net-free air space.in cubic feet AT= time interval between initial and final sump integrator reading in hours

Substituting Type A Test values, L' = 0.209 %wt/ day + (2400) (0.1338)(151)

(302,400)(24)

L' - 0.209 %wt./ day + 0.007 %wt./ day L' = 0.216 %wt./ day LOCAL LEAK RATE TEST ADJUSTMENT The level corrected leakage rate was adjusted to include Type B & C test results of isolation valves which were isolated from the Type A test pressure. The total leakage for this adjustment is the sum of all the isolated penetrations minimum leak rates. A summary of these test results is as follows:

LEAKAGE RATE (SCfH)

This value is equated to a leakage L rate in %wt./ day in order to be added in to the Type A Test results.

7.498 SCFH = 0.025 %wt./ day l

Therefore, the total post Type A Test Local Leak Rate Tests adjustment factor is an additional 0.025 %wt./ day.

SUPPLEMENTAL TEST In accordance with 10CFR50, Appendix "J", a supplemental test was performed at the conclusion of the Type A Test to provide a definitive method for verifying the measurement capability and integrity of the leak detection instrumentation.

The supplemental test utilized the superimposed leak verification method in which a calibrated leak was superimposed on the existing leaks in tae primary containment. A leakage rate of 3.14 SCFM was introduced into the leak detection system and the corresponding composite leakage rate was determined by utilizing the Absolute Analysis Method and the Mass Plot Calculational Technique. The results of the supplementai test are given in Table II.

As can be seen from the plot, near the latter part of the four (4) hour test, the UCL-95 leak rate begins to converge upon the measured leak rate.

i VI. TYPE A TEST

SUMMARY

AND CONCLUSION A. "As-Found" Results The results of the "As-Found" containment leakage rate exceeded the acceptance criteria required by 10CFR50, Appendix "J", due to excessive containment valve / penetration leakage as determined by the " pre-repair" Local Leak Rate Testing Program. Valve repairs and corrective maintenance were completed and the applicable valve " post-repair" leakage rate results were obtained in accordance with 10CFR50, Appendix "J". Both " pre-repair" and

" post-repair" results are included in Table III. Instrument tolerance factors were included in each LLRT test result.

-B. "As-Left" Results The results of the twenty-four hour Type A Test determined a primary

. containment leakage rate well below that required in 10CFR50, Appendix "J".

The accuracy of the test data has been verified by the satisfactory performance of a four hour supplemental test. It is therefore concluded that

-the validity of the test data has been confirmed and that all Type A Testing requirements of 10CFRSC, rependix "J", have been demonstrated.

VIII. TYPE B AND C LOCAL LEAK RATE TESTS Type B and C Local Leak Rate Tests were performed on all testable containment isolation valves, gaskets, and penetrations in accordance with 10CFR50, Appendix "J", and the Oyster Creek Technical Specifications.

A troubleshooting Local Leak Rate Test showed that the Drywell Sump Isolation Valve V-22-28 had an unacceptable leakage rate while the penetration's second isolation valve in series V-22-29, had an acceptable leakage rate. Since one of the penetration's redundant valves had an acceptable leakage rate, corrective maintenance was not performed prior to the Type A test. The local leakage rate result for the penetration was included

-in the local leak rate test adjustment to the Type A Test.

Because of an unacceptable leakage rate, Drywell Purge Isolation Valve V-27-3 was removed prior to the Type A Test and a blind flange was installed in its place. Since the penetration's other redundant valve V-27-4, had an acceptable leakage rate, a tap in the flange was vented to Reactor Building pressure to ensure that the penetration was not isolated from the Type A Test pressure.

The Hydrogen Sensing Lines modification was not completed prior to the Type A Test, therefore, the system was capped and isolated. Type B & C Tests were performed when the modification was complete and the results were included in the local leak rate test adjustment-to the Type A test.

The following is a summary of all valves / gaskets which had an unacceptable leakage for their pre-repair tests. Valves V-1-106, 107, and V-6-395 have been replaced, and the valve packing has been changed. The stem on Valve V-27-1 was adjusted. Valve V-22-28 received a new seat, stem, and plug.

Valve V-22-29 had its seat lapped. Valves V-27-3 and V-27-4 received new seats and the Drywell Head had a new seal installed.

All penetrations passed their subsequent post-repair Local Leak Rate Tests.

SUMMARY

OF TEST RESULTS 20 psig (SCFH) 35 psig (SCFH)

Tetsi (Post-Repair) 102.02 131.75 Total (Pre-Repair) FAILED TO MEET ACCEPTANCE CRITERIA.

IX. SECONDARY CONTAINMENT LEAK RATE TESTS Secondary Containment Leak Rate Tests were performed in accordance with 10CFR50 and the Oyster Creek Technical Specifications on four different occasions during the Cycle 10 Refueling Outage. The test conducted on 2/13/83 was then performed prior to refueling.

On March 18, 1984, a test was performed which failed to meet the acceptance criteria due to a high flow reading through the Standby Gas Treatn'ent System (SGTS). It was determined that this flow reading was not indicative of the true flow when a defective joint in the Pitot Tube and an obstructed flow to the Pitot Tube were discovered. These problems were corrected and a subsequent test was performed on March 19.

The test conducted on March 19 showed acceptable results for SGTS filter train #1, however, SGTS filter train #2 showed unacceptable results due to a high flow rate. The flow rate was adjusted to a lower flow rate by closing SGTS #2 damper arm about 5/8". Functional testing was then performed on SGTS

1. 2 flow rate with satisfactory results on March 19, 1984 A chronological summary of the test results is as follows:

DATE CORRECTED FLOW (CFM) VACUUM (IN. H30) RESULTS 2/13/83 2511 .251 Acceptable 5/10/83- 2423 .357 Acceptable 3/18/84 3779 .388 Unacceptable 3/19/84 2749 (SGTS #1) .391 2878 (SGTS #2)

• Results acceptable for SGTS filter train #1, unacceptable for filter train

CALCULATIONAL METHODS

\

Reference li. ANSI 56.8-1981, Containment System Leakage Testing Requirements.

The containment leakage rate c&lculation was performed in accordance with y ~~ '

the above standard and utilized the Absolute System Analysis Method and Mass Plut Calculational Technique.

The Analysis Method consisted of determining the mass of air in the containment, absolutely, using the ideal gas law, at each time point during the test and then using a straight-line least squares analysis to calculats

_ ,j the containment leakage rate. ,

5

) .An exact upper one-sided limit of 95% confidence level is then applied to the leakage rate using the relationships identified below. The derivations

v. -

and details for this calculational method can be found in reference 1. ,

The calcuational methods employed in the computer code for the mass point technique performs a least squares analysis as follows:

NOTE: Symbols are defined at the end of this section.

The least squares line is given by A

W = At + B where the slope (A) and intercept (B) are given, respectively by A-N(2,bW4)-(25Wi) ()S t4 )

N(25t )-()St) t t e'" .

and p B - (2$W4) ()$ t 42 ) - (23ti W4 ) ( 23t; )

2 N (Ett) . ( 7.,tt)2 5

-- - , , + , , , - -

Each time interval t i s the elapsed time between a clock time for the initial reading and the clock time at which the ith reading is taken. The formulas for A and B do not require equal time intervals.

The' leakage rate is expressed as the ratio of the rate of change of the mass and the mass in the con'tainment at the time t = 0. The values of t have. units of hours and since the leakage rate is desired in 7.wt./ day the estimated mass point leakage rate, expressed as a positive number, is calculated as follows:

Lam = (-2400) (A/B)

The uncertainty in the estimated value of the leakage rate is assessed in terms of the standard deviations of A and B and their convariance followed by -

1- the computation of an upper limit of the 95th confidence level for the calculated leakage rate.

The best estimate of the common standard deviation of the air masses with respect to the line is given by:

~

i Sb( W 9)2 where, ' -

Ni i s the measured mass at time ti and A A Wi is the estimated mass at time ti from Wi - Att+B and, N-2 is the number of degrees of freedom, In order to determine the standard deviation of the slope (S) let K= S

[N(2ti ) - (Eti ) ]

then, the standard deviation of the slope is S 3 - K[N]I ,

the standard deviation of the intercept is Sg = K(( ti2 ))

and the covariance of the slope and intercept is-

2 UCL (+95) - -2400 [b - (b -ac)I]/a l The leakage rate is later corrected for changes in containment free-air volume due to water leakage into the containment. Changes in reactor vessel water level are automatically accounted for in the computer program in each -

data set.

I Data for drybulb temperature and dewpoint temperature is corrected for any instrument error using three point calibration data provided by the L

equipment supplier. Weighting factors are assigned to the RTD Sensors and dewpoint sensors thus providing a mean absolute temperature reading indicative of the actual containment conditions.In addition, the pressure sensor readings ,

are corrected using a similar technique. The mass flow sensor readings are corrected using a fifth order polynomial equation. l 4

COMPUTER CODE QUALIFICATION:

An independent audit including a validation and verification was performed on the computer code prior to its utilization for the 1984 Primary Containment Integrated Leak Rate Test at Oyster Creek. The audit consisted a technical in-depth check of the equations used to confirm agreement with those equations recommended by the governing standards. In addition, the ILRT

-computer code was run using benchmark data obtained from previous ILRT tests conducted at Oyster Creek.

ATTACHMENT II LEAK RATE DETECTION SYSTEM The leakage rate detection system consists of thirty (30) four-wire platinum Resistance Temperature Detectors (RTD's) and ten (10) lithium chloride dew cells positioned in the containment structure as illustrated in Figure III. The analog signals from these sensors are input to a multiplexer scanner also positioned inside the containment. A data acquisition storage system located external to the primary containment interrogates the scanner on demand for temperature and humidity information.

Containment absolute pressure information is input to the data acquisition system from a pair of fused quartz bourdon tube manometers which are connected external to the containment. The analog signals are processed

~through an analog to digital converter and transmitter at preset intervals to a PRIME 750 computer. A system sensitivity check is performed by superimposing a known leak through a calibrated mass flow transducer. The output from the transducer is also processed via the analog to digital converter.and data acquisition system to the computer. In addition, the system reads and records the external ambient temperature and pressure.

The computer operates in a real time mode to collect the transmitted information and calculates on demand the containment leakage rate. Figure IV is a detailed functional block diagram of the Leak Rate Detection System.

Also included in this section are individual appropriate competent performance specifications.
