REPORT ON YANKEE ATOMIC ELECTRIC COMPANY, CORE III i

Dear Dr. Seaborg:

.j.

j At its forty-eighth meeting on July 11-13, 1963, at Los Alamos, New Mexico, d the Advisory Comittee on Reactor Safeguards considered Proposed CbFnge No. 36 which refers to refueling the Yankee reactor with Core III. The .

E proposal involves a change in the loading pattern and fuel enrichment as well as the use of boric acid at power. The Comittee had the benefit of g the referenced documents and discussions with representatives of Yankee Atomic. Electric Company, Westinghouse Electric Corporation, and the AEC ,,]

Regulatory staff. _.

J On February 10, 1962, the Comittee, in response to a request from the Comission, reported on increased enrichment for the proposed Core III l and the use of boric acid in the primary coolant at power. At that time, information on the design of the new core and a complete safety analysis I were not available and several unresolved areas were indicated.

Since then, complete design details have been provided and questions rela-tive to such items as shut down margin, integrity of the boron injection system, and control rod worth have been resolved. On the basis of the information presented, the Advisory Committee on Reactor Safeguards believes that the proposed Core III loading and operation up to full power'with boric acid in the primary coolant may be carried out without undue hazard to the health and safety of the public.

Dr. T. J. Thompson did not participate in this review. .g Sincerely yours, I

.' l
