UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 Honorable Joseph M. Hendrie Chairman
- u. s. Nuclear Regulatory Commission Washington, DC 20555 June 7, 1978 REPORI' ON MAINE YANKEE A'IDMIC POWER STATION
Dear Dr. Hendrie:
During its 218th meeting, June 1-2, 1978, the Advisory Committee on Re-actor Safeguards completed its review of the application by the Maine Yankee Atomic Power Company for authorization to operate the Maine Yan-kee Atomic Power Station at power levels up to 2630 MW(t).
A subcom-mittee meeting on this matter was held in Washington, D. C. on May 25, 1978. The Committee had previously reported favorably on operation of the Maine Yankee Atomic Power Station at power levels up to 2440 M'fl(t) in its report of January 13, 1972. During this review, the Committee had the benefit of discussions with representatives of the Maine Yankee Atomic Power Company, Yankee Atomic Electric Company, Combustion Engi-neering Incorporated, and the Nuclear Regulatory Commission Staff. The Committee also had the benefit of the documents listed.
In the NRC Staff review of the request to increase power, analyses of accidents and transients, physics tests, fuel performance and site me-teorology were carried out. Modifications to the Technical Specifica-tions were also considered. In addition, the NRC Staff reviewed the operating history of the plant. In evaluating the proposed power in-crease in each of these areas, the NRC Staff used current NRC criteria.
The NRC Staff has concluded that operation at the proposed power level in accordance with the proposed Technical Specifications is acceptable.
The ACRS concurs.
The Advisory Conmittee on Reactor Safeguards believes that there is rea-sonable assurance that the Maine Yankee Atomic Power Station can be oper-ated at power levels up to 2630 MW(t), without undue risk to the health and safety of the public.
Sincerely,
~!r~
