Subject:
. Type A Integrated Containment Leakage Rate Test Gentlemen:
1 Section 4.4.1.1 of the Technical Specifications to our operating license specifies that all Type. A integrated containment leakage rate tests "will be performed in accordance with the provisions of 10 CFR 50.54-(o) and 10 CFR 50 F
Appendix J."
Section III.D.I.(a) of 10 CFR Appendix J states, in part, that
- )
"a' set of:three Type A tests shall be performed, at approximately equal intervals'during 'each 10-year service period. The third test of each set shall be conducted when the plant is shutdown for the 10-year plant inservice inspections."
Our. third Type A test for the current 10-year service period has been scheduled to be performed during the 1991 refueling shutdown (about December of 1991);'the previous two: tests were performed.in August of 1985 and October of 1988.
The 1991 refueling shutdown was also to have been the shutdown for the 10-year plant inservice inspections.
However, because. of a commitment to inspect our reactor vessel thermal shield in 1990, we now plan to perform the.
required 10-year inservice inspection activities during the 1990 refueling shutdown.
We feel' it appropriate to maintain the sequencing of Type A '
. integrated containment leakage rate tests at every-second refueling shutdown,
.which results in three at approximately equal intervals during each 10-year
. service period. Therefore our plans for conducting the third Type A integrated
. containment leakage rate test during the 1991 refueling shutdown remain unchanged.
