Commonwealth Edison kSS A /N Ouad Cities Nuclear Power Station 22710 206 Avenue North Cordova, Illinois 61242 Telephone 309/654-2241 NJK-79-388 October 2$, 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 provide you with information concerning the release rates of radioactive materials, in gaseous and particulate forms, from the Quad-Cities Nuclear Power Station during the third quarter reporting period of 1979.
This information is preliminary 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, h
WLaa'/,
