SUBJECT:
. MILLSTONE UNIT 2, MODIFICATION OF SELECTED TESTING
- COMMITMENTS RELATED TO GENERIC LETTER 83-28 (TAC NO. MA3948)
Dear Mr. Necci:
. By letter dated September 30,1PM, the' Northeast Nuclear Energy Company (the licensee)
_ submitted a request for changes to certain commitments made on Action items 4.2.1,4.2.2,
.4.5.1, and 4.5.'2 with respect to Generic Letter (GL) 83-28 at Millstone Nuclear Power Station (Millstone), Unit 2. Since the implementation of GL 83-28, the licensee has been reevaluating
- its reactor trip circuit breaker (RTCB) maintenance program, trending RTCB parameters measured during testing, and performing ~on-line functional testing of the reactor trip system to
. ensure reliable RTCB operation. The licensee has determined that the RTCBs are being tested l
more frequently than necessary, which, in turn, could cause premature degradation of the breakers, and increase the probability of a test-induced plant transient. Therefore, the licensee
' proposes to modify commitments made for Action items 4.2.1,4.2.2,4.5.1, and 4.5.2 of GL 83-28 by providing additional justificab9ns or a safety basis for the changes.
- The staff has reviewed the proposed changes and did not identify any safety concerns, l.
l therefore, no further action is required by the staff. This completes our effort and closes TAC No. MA3948.
l Sincerely, p
