UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 January 22, 2010 Mr. David J. Bannister Vice President and CNO Omaha Public Power District Fort Calhoun Station 444 South 16th St. Mall Omaha, NE 68102-2247

SUBJECT:

FORT CALHOUN STATION, UNIT NO.1 - CORRECTION TO AMENDMENT NO. 263 RE: REQUEST TO ADD STEAM GENERATOR BLOWDOWN ISOLATION REQUIREMENTS TO TECHNICAL SPECIFICATIONS (TAC NO. ME0596)

Dear Mr. Bannister:

On October 9, 2009 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML092540591), the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 263 to Renewed Facility Operating License No. DPR-40 for the Fort Calhoun Station, Unit NO.1. The amendment consisted of changes to the Technical Specifications (TSs) in response to your application dated January 30, 2009, as supplemented by letters dated June 30 and August 28,2009 (ADAMS Accession Nos. ML090340536, ML091830041, and ML092440295, respectively).

Amendment No. 263 added steam generator blowdown isolation operability and surveillance requirements to the TSs. These requirements will be needed as a result of a plant modification to add an interlock to automatically isolate steam generator blowdown following a reactor trip.

In addition, the amendment modified the remedial actions for channels that currently contain a key-operated bypass switch by deleting the term "key-operated" so that channels with a bypass switch that are not key-operated may be bypassed as well.

On June 30, 2008, the NRC staff issued Amendment No. 257 (ADAMS Accession No. ML081790191), which renumbered most of the pages in TS 3.1. Upon implementation of Amendment No. 257, what had been TS 3.1 - Page 13 became TS 3.1 - Page 14. Due to an administrative error, the NRC issued Amendment No. 263 which revised TS 3.1 - Page 14 improperly as TS 3.1 - Page 13 thereby creating two TS pages having the same page number, TS 3.1 - Page 13.

This administrative error did not impact Amendment No. 263 for FCS. The error does not change the NRC staff conclusions regarding Amendment No. 263 for FCS. Enclosed are corrected versions of TS 3.1 - Page 13 (Amendment 257) and TS 3.1 - Page 14 (Amendment 263). Please discard the associated pages from the previous amendments and replace them with the enclosed pages.
