in the enclosed Detailed Statement on the Revironmental Considerations prepared by AEC's Division of Reactor:Licensias.

Mise Zenser seems ta be concerned especiallyjhat the operation of the plant may cause an increase in. childhood cameer due to the exposures to pregnant women of 1-1/2 rems of radiation'. Emperienes with planta similar to Davis-Besse indicates that 4 e personiliving near the site boundary of the Davis-Besse nuclear power plant will imeurcassexpeowre r

Honorable Delbert Latta No unusual or unplanned stack releases have occurred at the Enrico Fermi Unit i nuclear power plant during the last two years.- During 1969 no I

gases were released. During 1970 radioactive gaseou releases were'less than 10% of those permitted by the technical specif tions of-the AEC license for the plant-Miss Eenser may be referri to an operating malfmaction at the Fe.mi' plant which occurred in tober 1966,'and resulted in the plant being shut down for almos four yes~s.

%ne Docket No. 50-346 i

Honorable Delbert Latta House of Representatives

Dear Mr. Latta:

This is in response to your letter of January 22, 1971, which enclosed two letters from Miss Sandra L. Zenser er. pres' lug concern about the Davis-Besse Nuclear Power Station near Oak Hatoor, Ohio, in response to a number of inquiries, we have prepared the enclosed sununary which describes the proceedings concerning the licensing of the Davis-Besse plant. In additicn, Miss Zenser may be interested in the enclosed Detailed Statement on the Environmental Considerations prepared by AEC's Division of Reactor Licensing.

Miss Zenser seems to be concerned especially that the operation of the plant may cause an increase in childhood cancer due to the exposures to pregnant women of 1-1/2 rems of radiation.

Experience with plants similar to Davis-Besse indicates that no person living near the site boundary of the Davis-Besse nuclear power plant will incur an exposure anywhere near 1-1/2 rems of radiation. The increase in radiation exposures to persons living at the plant boundary as a result of releases of radioactf.vity in effluents from the Davis-Besse plant are expected to be less than 0.001 rem (1 millirem) per year, or approxi-mately 1/100 of t! a radiation exposure the average person in the United

Honorable Delbert Latta No unusual or unplanned stack releases have occurred at the Enrico Fermi Unit 1 nuclear power plant during the last two years.

During 1969 no gases were released.

During 1970 radioactive gaseous releases were less than 10% of those permitted by the technical specifications of the AEC license for the plant. Miss Zenser may be referring to an operating as1 function at the Fermi plant which occurred in October 1966, and resulted in the plant being shut down for almost four years. As a result of a blockage of coolant flow, two fuel elements overheated and partially melted, which resulted in the release of radioactivity to the sodium coolant.

Some of this radioactivity leaked from the primary system into t% containment building and a small fraction of the gaseous activity usus released escaped to the atmosphere. No measurable offsite radiation was detected.

If we can be of any further assistance, please let me know.

Sincerely, Harold L. Price Director of Regulation Enclosures :
