s 4.5-3 In the event the leak rate of any test exceeds the allowable test rate Lt(20), the condition shall be corrected, the testing frequency shall revert to the following schedule, within plus or minus 8 months, as follows:

1. Within ?2 months following the retest made (local or integrated) to correct excess leak rate.

2. Within 24 months of Test 1.

3. Within 48 months of Test 2.

E. Local Leak Rate Tests

1. Primary containment testable penetrations and isolation valves shall be tested at a pressure of 35 psig each refueling outage except bolted double-gasketed _ seals shall be tested whenever the seal is closed after being opened, and at least at each refueling outage.

2. Personnel air lock door seals shall be tested at a pressure of 10 psig eacn refueling outage.

3. Containment components not included in 1, and 2, which required leak repairs following any integrated leakage rates in order to meet the allowable leakage rate unit Lt shall be subjected to local leak tests at a pressure of 35 psig at each refueling outage.

4. The main steam line isolation valves are to be tested at a pressure of 20 psig during each refueling outage.

F. Corrective Action

1. If the total leakage rates listed below as adjusted to a test pressure of 20 psig, are exceeded, repairs and retests shall be performed to correct the condition.

a. The combined leakage rate of all penetrations and isolation valves subject to Type B and C tests 60% La(20)

b. Any one penetration or isolation valve 5% Lto(20) i s
