W. G. Counsil letter to D. G. Eisenhut. dated December 31, 1980.

Gentlemen:

Millstone Nuclear Power Station, Unit No. 2 Auxiliary Feedwater Flow Indication Item II.E.1.2 described in NUREG-0737 requires that safety grade auxiliary feedwater flow indication be provided at Millstone Unit No. 2 by July 1, 1981. In Reference (1), Northeast Nuclear Energy Company (NNECO) docu-mented its intention to comply with the required in-service date in NUREG-0737 for Item II.E.1.2.

Due to an oversight on the part of the equipment vendor, NNECO will not receive control board mounting hardware for the auxiliary feedwater flow indicators in time to support the. required in-service date of July 1, 1981. This is documented in the attached letter from the vendor to NNECO.

Upon receipt of the subject hardware, NNECO will expedite the installation of the auxiliary feedwater flow indicators. The revised in-service date for this system is conservatively estimated to be August 1, 1981. NNECO has determined that the slight deviation from the schedule provided for in NUREG-0737 for this system is acceptable as the automatic initiation of the auxiliary feedwater system at Millstone Unit No. 2 is operational and provides increased assurance that adequate feedwater will be available to remove decay heat. Current auxiliary feedwater flow indication, al-though not scfety-grade, will provide adequato indication of auxiliary feedwater flow until the safety-grade system installation is complete.
