TENNESSEE VALLEY AUTHORITY Division of Power Production SECONDARY COIITAINMENT LEAK RATE TEST BROWNS FERRY NUCLEAR PLANT UNIT 1 CONDUCTED NOVEMBER 27, 1978 SUBMITTED TO THE UNITED STATES NUCLEAR REGULATORY COMMISSION PURSUANT TO FACILITY OPERATING LICENSE NUMBER DPR-33 790213 0097

e 1.0 - Browns Ferry Nuclear Plant Unit 1 Secondary Cont ainment Leak Rate Test Report 2.0 Purpose This report describes the results and analysis of the test data taken during leak rate testing of the Browns Ferry Nuclear Plant unit 1 secondary containment pursuant to Technical Specification 4. 7.C.1.c before the first refueling outage.

o 3.0 Procedure The attached surveillance instruction (SI), S1 4.7.C-1, outlines the procedures followed during secondary containment Icak rate testing.

4.0 Data The attached surveillance instruction data sheets list the following test data:

(1) Standby gas treatment system flow rate: 9,000 scfm (2) Reactor building differential pressures:

Unit 1 reactor zone:

-0.33" H O 2

Unit 2 reactor zone:

-0.30" H O 2

Unit 3 reactor zone:

-0.29" H O 2

Refueling zone average:

-0.31" H O 2

(3) Wind Speed:

3.5 mph (4) Wind direction: southeast 5.0 Analysis and Interpretation Technical Specification 4.7.C.l.c requires that secondary containment capability to maintain 1/4-inch water vacuum under calm (<5 mph) wind conditions with a total system inleakage rate of not more than 12,000 ocfm shall be demonstrated at each refueling outage before refueling.

sllowing shutdoen of unit 1 on November 27, 1978, the secondary containment for the common refuel zone and the unit reactor zone were leak rate tested.

Browns Ferry Nuclear Plant Unit Secondary Containment Leak Rate Test Report (Continued) 5.0 Analysis and Interpretation (continued)

These two zones were isolated from the unit 2 and unit 3 reactor zones.

Appendix A to S1 4.7.C gives the allowable inleakage per secondary containment zone documented during preoperational testing. Assuming a total allowable inleakage of 12,000 scfm, it is shown in Appendix A that the allowable inlerkage for testing the refuel zone and unit I reactor zone in combination under calm wind conditions is 9,204 scfm. From the data taken during this test, it is shown that, assuming a total combined inleakage of 9,000 scfm in the unit reactor zone and the refuel zone, the secondary containment system is capable of maintaining greater than 0.25 inches of water vacuum.

These results fulfill the requirements of Technical Specification 4.7.C l.c.

The reactor building is broken up into four zones, each of which can be isolated independently. These zones are the unit I reactor zone (UlRZ), the unit 2 Reactor zor.e (U212Z), the unit 3 reactor zone (U3RZ), and the refueling zone RFZ) which is common to all three units.

This surveillance instruction is written to use the SCTS fans A and C, B and C, ur A and B, or.a singic fan to demonstrate th'at at a flow of 5 12,000 cfm the secondary containment zones can be maintain,cd at a ntatic pressure of -1/4" water under calm wind conditions. Manual isolation of a

SI 4.7.C - Secondary containment Description (Continued)

SI 4.7.C-1 will be used to demonstrate secondary containment capability.

This is to be accomplished by isolating the secondary containdent for the reactor building or the required zones, starting the standby gas treatment trains, adjust-ing the flow to less than the allowable flow and verifying the static pressure of the tested zone (s) is -1/4" 110 or less. This procedure vill normally be used to 2

test the secondary containment capability of the reactor building prior to refueling.

(

SI 4.7.C-1 testing should bc Ifmited to 30 minutes if at all possible since the main steam line tunnel temperatures may trip an operating unit.
