II. The local leak rate tests on all boundary valves and penetrations were conducted during the Unit 3 refueling shutdown from October 7, 1974, to December 4, 1974, to meet the refueling surveillance requirements.

The following procedures were used:

Operating Procedure 13514.1 - Personnel / Emergency Air Locks Operating Procedure 13531.1 - Equipment Access Hatches Operating Procedure 13104.1 - Containment Purge Valves Operating Procedure 13404.2 - Electrical Penetration Canisters Operating Procedure 13404.1 - Containment Isolation Valves Operating Procedure 16004.1 - Fuel Transfer Tube Flange The total "as-found" leak rate was 125.67% of the maximms allowed in Section 4.4.2 of - he Technical Specifications.

Repairs and retests were made and the total leak rate at the time of heat up above 2000F was 21.21% of the maximum allowed in Section 4.4.2.

As part of the local leak rate tests, the following valves were repaired to reluce their respective leak rates:

l III. Th'e local leak rate tests on all boundary valves and penetrations were conducted during the unit #3 refueling shutdown from October 25, 1975, through December

( 11, 1975. l i.

The following procedures were used; Operating Procedure 13,514.1, Personnel /Emergenty Air Locks Operating Procedure 13,531.1, Equipment Access Hatch Operating Procedure 13,104.1, Containment Purge Valves Operating Procedure 13,404.2, Electrical Penetration Canisters Operating Procedure 13,404.1, Containment Isolation Valves Operating Procedure 16,004.1, Fuel Transfer Tube Flenge The total "as found" leak rate was 546% of the maximum allowed in Section 4.4.2 of the Technical Specifications. .

Repairs and retests were made and the total leak rate at the time of heat-up above 2000F was 27% of the maximum allowed in Section 4.4.2.

A new maximum allowable leak rate was established using La of .25% per day as per Appendix J of 10 CFR 50.
