1.0 Browns Ferry Nuclear Plant, Unit 3 Secondary Containment Leak Rate Test Report 2.0 ~Pue eee This report describes the results and analysis of the test data taken during leak rate testing of the Browns Ferry Nuclear Plant Unit 3 secondary containment pursuant'o Technical Specification

'4.7.C.l.b prior to each refueling outage.

3.0 Procedure The attached surveillance instruction, SI 4.7.C-l, outlines the procedures followed during secondary containment leak rate testing.

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

(1) Standby gas treatment system flow rate: 8,600 scfm (2) Reactor building differential pressures:

Unit 3 reactor zone: -0.25" H20 Refueling zone average: -0.25" H20 (3) Wind Speed: 4 mph (4) Wind Direction: South

5.0 Anal sis and Inter retation Technical Specification. 4.7.C.l.b 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 scfm shall be demonstrated at each refueling outage prior to refueling.

Following shutdown of Unit 3 on August 20, 1979, the secondary contain-ment for the common refuel zone and the Unit 3 reactor zone were leak rate tested. The results show that Unit 3 reactor zone and refuel are capable of maintaining <-.25" with less than the allowed I'ones H 0 2

flow.

Page 2 BF SI 4.7.C 8/21/79 SI 4.7.C Secondar Containment SI 4.7.C-1 will be used to demonstrate secondary containment capability.

This is to be accomplished by isolating the secondary containment for the reactor building or the required zones, starting the standby gas treatment trains, adgust-ing the flow to less than the allowable flow and verifying the static pressure of the tested zone(s) is -1/4" H20 (or less as required by Table 1 for varying wind speeds). This procedure will normally be used to test the secondary containment capability of the reactor building prior to refueling.

Note; Wind speed and direction measurements will be taken from the site meteorological tower instrumentation and will be assumed to be acceptably accurate representation for the conditions at the reactor building.

CAUTION: This testing should be limited to 30 minutes if at all possible since the main steam line tunnel temperatures may trip an operating unit.

Leak rate testing will normally be done with all zones simultaneously lined up for testing; however, plant operating conditions and the technical specificatxon do not always permit this. Hhen less than four zones (3-unit plane) are being tasted, the total allowable inleakage will be based on preopcrational testing and will be on the sum of the allowable inleakages for the zones being tested. After a base'econdary containment violation, the total inleakage must not be greater than the total of the allowable inleakage for each individual zone as indicated below.

The technical specifications require the total secpndagy containment inleakage to be less than 12,000 cfm at -1/4" differential pressure. The following are therefoxe established for surveillance'estirg various combinations oi zones when secondary containment has been violated.
