Reference:
(a) Licerse No. DPR-36 (Docket No. 50-309)
(b) USNRC Letter to All Operating Reacter Licensees, dated May 7, 1980 (c) USNRC Letter to All Operating Reactor Licensees, dated March 28, 1980
Subject:
Five Additional TMI-2 Related Requirements
Dear Sir:
Your letter, Reference (b), transmitted five items from the NRC TMI Action Plan which, applicable to operating reactors, constitute a second set of requirements for operating reactors. Maine Yankee was requested to reply within 30 days stating our commitments to meet the additional requirements and associated schedules.
The attachment to this letter provides a tabulation by item of the eleven requirements specified in Reference (b) and our specific plan to address each. Maine Yankee recognizes our obligation to respond to NRC requests for information and it is our intention to be fully responsive in this regard.
However, we trust that the NRC staff recognizes that Maine Yankee, as the 21censee, bears the full weight of responsibility for the safe operation of our facility. In the felfillment of our responsibilities, we are obligated to parform independent, plant specific assessments of any additional requirements prior to implementation, to assure that the collective impact of NRC requirements will not compromise existing system safety and reliability. This overall assessment of the collective impact of the requirements was recommended by the Bulletins and Orders Task Force in Item B.15 of NUREG 0626.
