Dear Mr. Randazza:
The Commission has issued the enclosed Amendment No. 98 to Facility Operating License No. DPR-36 for the Maine Yankee Atomic Power Station. This amendment consists of changes to the Technical Specifications (TS) in response to your application dated February 24, 1987.
This amendment modifies the Technical Specifications to reflect revised Loss of Coolant (LOCA) Limits.
These revised LOCA Limits were detemined using a revised delta P injection j
penalty factor during the reflood phase of LOCA's and limiting axial power j
shapes. The revised delta P injection penalty factor and the method to select the limiting axial power shapes wera proposed and justified in the Maine Yankee Atomic Power Company (MYAPCo) letter to NRC dated November 10, 1986.
These proposed revisions to the Emergency Core Cooling System (ECCS) Evaluation Model were reviewed and found acceptable in the NRC letter to MYAPCo dated January 6,1987.
A copy of the Safety Evaluation is also enclosed. The' notice of issuance will l
be included in the Commission's next regular bi-weekly Federal Register notice.
