Quad Cities Nuclear Power Station

@ Commonwealth Edison 22710 206 Avenue North Corcova, Illinois 61242 Telephone 309/654-2241 NJK-79-388 October 125, 1979 J. Keppler, Regional Director Office of Inspection and Enforcement Region III U. S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, IL 60137

Dear Mr. Keppler:

The purpose of this letter is to pre de you with information concerning the release b : of radioactive materials, in gaseous and pnc : : alate forms, from the Quad-Cities Nuclear Power Station during the third quarter reporting period of 1979.

This information is prelininary in nature be-cause analyses for strontium-89 and strontium-90, on the August and September particulate composite samples, have not been completed yet. An estimate has been made using the July strontium release rates assumed constant over the entire reporting period.

Based on isotopic analyses and the aforementioned estimates, the release rate of radioiodines and radio-active particulates with half-lives greater than eight days was 1.04 times the annual design objective for the third quarter of 1979. A monthly breakdown is as follows: ,

Month Multiple of Design Objective July 1.12 August 1.06 (estimate)

September 0.94 (estimate)

The Station is continuing its efforts to mini-mize these releases.

Sincerely, l}h] j}(
