Dear Mr.. Frizzle:

SUBJECT:

EMERGENCY RESPONSE CAPABILITY - CONFORMANCE TO REGULATORY GUIDE 1.97, REVISION 3 (TAC 51103)

We are transmitting herewith our subject safety evaluation with its attachment, EG&G Idaho, Inc., Technical Evaluation Report (TER) dated April 1989. We find the instrumentation provided by Maine Yankee Atomic Power Company for meeting the recommendations of Regulatory Guide 1.97, Revision 3, acceptable except for the variables accumulator tank level and pressure and containment sump water temperature. Our safety evaluation is based on our review of EG&G's TER EGG-NTA 7083.

The acceptability of instrumentation for accumulator tank level and pressure and containment sump water temperature will remain open pending the outcome of the staff's review of the need for environmentally qualified instrumentation to monitor these variables. The staff's conclusion will be reported when the generic review is complete.

An appropriate' implementation schedule will be developed by the Project Manager via discussion with the licensee. Once the schedule is established, you are required to inform the Commission, in writing, of any significant changes in the established completion schedule identified in the staff's safety evaluation and when the action has actually been completed.

Sincerely, r,gg Utiginalsigned by:
