UNITED STATES NUCLEAR REGULATORY C0t411SSION DOCKET NO. 50-10 COMMONUEALTH EDISON COMPANY NOTICE OF RE0 VEST FOR EXTENSION OF ECCS EXEMPTION p
The Comonwealth Edison Company (the licensee) is authorized by Facility Operating License No. CPR-2 to operate a nuclear power reactor identified as Dresden Nuclear Power Station Unit No.1 (the facility) at the licensee's Dresden Nuclear Power Station, located in Grundy County, Illinois, at steady state power levels up to 700 tiWt.
On August 21, 1975, the U.S. Nuclear ?,egulatory Commission (the Commission), granted the licensee an exemption from the requirements of Section 50.46 of 10 CFR Part 50 of the Commission's regulations re-lating to emergency core cooling system (ECCS) design considerations, but not from the specific perfomance requirements of the Final Accep-tance Criteria (FAC). That exemption gave the licensee until December 31, 1977, to comply with the requirements of and underlying 10 CFR 50.46 with respect to the desigrr and diversity of the facility's emergency cystems or the diversity of emergency power sources.
Notice is hereby given that th'e Commission has received and is considering a request dated July 8,197f, from the~ licensee for an extension of the date of compliance from December 31,1977 to December 31, 1978, of the previous exemption issued on August 21 1975.

- The licensee has filed, along with its exemptie extension request and in support thereof, a number of affidavits.
The affidavits provide details on the need for the extension, costs for replacement power, and m._
the additional action.that the licensee is taking to further protect the health and safety of the public during the extension period.
The licensee asserts that the additional measures to improve ECCS reliability, the affidavits, and other items discussed in the application demonstrate that for this facility, the public interest favors the extension.
The exemption extension may be granted by the Director, fluclear Reactor Regulation upon a finding pursuant to 10 CFR 550.12 that such exemption is authorized by law and will not endanger li fe or property, or the common defense and security and is otherwise in the public interest.
The operating limitations set forth in the licensee's submittal.
in accordance with 10 CFR 550.46(a)(2)(iv) are no longer effective.
Since that submittal, a new core has been approved for use in operation
.g of the facility having different fuel thermal and hydraulic characteristics, which have necessitated a revised ECCS performar.ce evaluation, and revised ECCS-based operating limitations. Consequently, the procedural require-ments of 10 CFR 550.46(a)(2)(vi) are not applicable to the requested exemption extension.
The Director of Nuclear Reactor Regulation finds that it is appropriate to provide interested persons with an opportunity to comment on the exemption extension request similar to that provided by the Commission in connection with the prior requests.
The Director therefore invites the submission o'f views and comments by interested persons concerning the extension request and the proposed action.
Such views and comments should be submitted in
