SUBJECT:

ISSUANCE OF EXEMPTION FROM THE REQUIREMENTS OF 10 CFR 70.24 -

FORT CALHOUN STATION, UNIT NO.1 (TAC NO. M99544)

Dear Mr. Gambhir:

By letter dated August 29,1997, as supplemented by letter date October 23,1997, Omaha Public Power District requested an exemption from the requirements of 10 CFR 70.24 concerning criticality monitors.

Based upon the information provided, there is reasonable assurance that irradiated and unirradiated fuel will remain subcritical; furthermore, you maintain radiation monitors in accordance with General Design Criterion (GDC) 63. The low probability of a criticality together with your adherence to GDC 63 constitute good cause for granting an exemption from 10 CFR 70.24.

The U.S. Nuclear Regulatory Commission, pursuant to 10 CFR 70.14, has issued the enclosed exemption for Fort Calhoun Station, Unit No.1. A copy of the exemption is being forwarded to the Office of Federal Register for publication.
