Dear Mr. Opeka:
Gray File 3.5a By your letter dated November 6, 1985, you requested NRC approval of the schedule for the Type "A" containment leak rate tests for Millstone Unit 2.
This approval is required by 10 CFR Part 50, Appendix J, Section III.A.6(a) in that the results of the previous Type "A" test failed to meet the applicable acceptance criteria.
We have reviewed your November 6, 1985 request for Type "A" test schedule approval together with additional information provided in your letter dated June 18, 1986.
As indicated in the enclosed Safety Evaluation, we conclude that your proposed Type "A" test schedule is acceptable provided that:
(1) A preventive maintenance program for Fisher valves be initiated to include replacement of the T-ring gaskets; (2) Traps or screens be provided to prevent debris from entering the sump valve's seat area; (3) Local Leak Rate Tests (LLRT) for identified " problem" valves be conducted; (4) NRC Region I will be notified of any Type B and/or Type C test results which indicate excessive leakage.
With regard to the above, every reasonable effort should be made to complete the above remedial actions during the Fall '86 refueling outage.
Within 30 days following startup from your Fall '86 refueling outage, please inform us regarding the status of the above remedial actions.
Sincerely,
/S/
Ashok C. Thadani, Director PWR Project Directorate #8 Division of PWR Licensing-B
