TYPE A TEST METHODS AND TEST RESULTS i

The containment leakage rate was determined by utilizing the Absolute Analysis l

Method and the Mass Plot Calcula;ional Technique.

Changes in the water level of the reactor vessel were computed and included in each data set collection.

l At the conclusion of the test, the results of the Absolute and Mass Plot l

Methods were corrected to account for changes in the containment net-free air l'

4 j

space due to water accumulation in the drywell sump.

These results were l

further adjusted to incorporate the results of Type B and Type C Local Leak l

Rate Testing (LLRT) for isolation valves which were not exposed to the test 1

j pressure.

The level corrected leakage rates and the LLRT adjusted leakage a

l rates are given below. A calculation of leakage for the last eight hours of 4

l the test was also conducted to insure that the as-left condition of the containment remained below the acceptance criteria.

i 1

LEVEL CORRECTION CALCULATION j

The UCL-95 calculated leakage rate was corrected to account for water l

accumulation into the containment sump as determined by the following equation:

I h

LI = L + (24)(0.1338)(F1 - Fn) (100)

(310,916) T I

7 LOCAL LEAK RATE TEST ADJUSTMENT The level corrected leakage rate is adjusted to include types 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 the isolated penetration minimum leak rates.

A summary of these test results is as follows:

Leakage Rate (SCFH)

Penetration 0 20 psig Cleanup System from Reactor 2.741 Cleanup System to Reactor 0.1041 1

q The post type A test local leakage rate adjustment is 5.8513 SCFH corrected to a test pressure of 20 psig.

This value must be converted to a leakage rate in

% wt./ day and included in the type A test as an added Local Leak Rate

{

1 adjustment factor.

5.8513 SCFH = 0.0183 % wt./ day Therefore, the total post-type A test adjustment factor is an additional 0.0183% wt./ day The type A test results at the measured and at the 95% confidence level for the Absolute Mass Plot method are given below in Table I.

Both the reactor

j ANALYSIS AND INTERPRETATION I

Figure I is a graphical description of the type A test performance as l

determined by the Absolute Mass Plot Analysis technique.

As previously described in Section II, each data point is corrected for reactor water level by calculating the corresponding change in air mass inside the reactor i

i vessel. As displayed in Figure I, the leakage rate steadily decreased I

throughout tne test period and the UCL-95 leakage rate moved steadily toward convergence with the measured leakage rate.

In addition, the last eight hours leakage calculation further verifies the decreasing leakage rate trend and i

}

assures the integrity of the containment, j

SUPPLEMENTAL TEST i

Ir 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 1

the measurement capability and integrity of the leak detection instrumentation.

s The supplemental test utilized the superimposed leak verification method in

)

which a calibrated leak was superimposed on the existing leaks from the primary containment.

A leakage rate of 3.20 SCFM was introduced into the leak j

i detection system and the corresponding composite leakage rate was determined

TYPE A TEST

SUMMARY

AND CONCLUSION A.

"As-Found" Results The results of the "As Found" containment leakage rate met the acceptance criteria required by 10CFR50, Appendix "J".

Local leak rate testing prior to type A testing indicated no excessive leakage of any testable penetration which could result in an unsatisfactory type A test.

During type A testing, containment leakage was far below the acceptance criteria for the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test period.

The data was verified by completing a satisfactory supplemental test.

It is, therefore, concluded that the type A "As Found" test was successfully completed and the containment integrity cequirements were far better than required by 10CFR50, Appendix "J".

B.

"As-Lef t' Results 1

The results of the twenty-four hour type A test determined a primary.

containment leakage rate well below that required by 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 has met the acceptance criteria of 10CFR50, Appendix "J".,

Secondary Containment Leak Rate Tests Secondary containment leak rate tests were performed in accordance with 10CFR50 and Oyster Creek Technical Specifications on two different occasions.

The acceptance criteria of the test is satisfied if the Reactor Building is capable of maintaining.2 0.25 inches H O vacuum with a Standby Gas 2

Treatment System flow rate of 2600 CFM + 260 CFM.

The test conducted on 10/30/87 was performed prior to startup and operation.

On October 28, 1987, a test was performed which failed to meet the acceptance criteria due to a low Reactor Building vacuum.

It was discovered that ongoing repair of the Reactor Building roof at the time of the test has allowed outside air to enter the Reactor Building.

The repair work was completed and a subsequent test was performed on October 30, 1987 with satisfactory results.

A chronological summary of test results is as follows:

Attachment I CALCULATIONAL METHODS Reference 1.

ANSI 56.8-1981, Containment System Leakage Testing Requirements.

The containment leakage rate calculation was performed in accordance with the above standard utilized the Absolute System Analysis Method and Mass Plot 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-lin? least squares analysis to calculate the containment leakage rate.

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

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

The calculational 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) are intercept (B) are given, respectively by:

(EW )(Ett)

N(Et W1) 1 t

A=

(Ett)*

N(Et *)

t and (EWt)(Et

) - (Et W )(Ett) t t t B=

N(Et 2) - (Ett)'

1 Each time interval (t) is the elapsed time between a clock time for the initial reading and the clock time at which with it" 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 containment at the time t = 0, The values of t have units of hours and since the leakage rate is desired in %wt./ day the estimated mass point leakage rate, expressed as a positive number, is calculated as follows:

L = (-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 covariance followed by the computation of an upper limit of the 95th confidence level for the calculated l

leakage rate.

1 _,

The best estimate of the common standard deviation of

. the air masses with respect to the line is given by:

[E(W-W)2)t/2 S=

N-2

where, Mt is the measured mass at time t 1 W

is the estimated mass at time t from W

= At

+ B 1

i 1

t and, N-2 is the number of degrees of freedom, In order to determine the standard deviation of the slope (S) let S

K=

[N(Et ')

- (Ett)']*

t then, the standard deviation of the slope is Sa+K(N)1/2 l

the standard deviation of the intercept is

)1/2 So=K(Ett and the covariance of the slope and intercept is San =K'(-Ett)

In order to calculate the exact upper one-sided limit of a 95% confidence level for the leakage rate, let 2

a a=B

- tos (San),

b = AB - tos (Sao), and 2

c = A' - tos (3,)2 a

Then the exact upper one-sided limit of a 95% confidence 4

level for the leakage rate is determined as follows:

UCL (+95)

-2400 [b -(b2-ac)1' ] /a

=.

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.

Data for drybulb temperature and dowpoint temperature is corrected for any instrument error using three point calibration data provided by the equipment supplier.

Weighting factors are assigned to the RTD Sensors and dewpoint sensors thus providing a mean abolute 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 for any instrument error using fifth order polynominal equation as a best curve fit to the calibration data provided by the equipment supplier.

COMPUTER CODE QUALIFICATION I

An independent audit including a validation and verification was performed on the computer code prior to its utilization for the 1987 Primary. Containment Integrated Leak Rate Test at Oyster Creek.

The audit consisted of. 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 tes:ed 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 component performance I

specifications.
