FORT CALHOUN STATION, UNIT 1 - NRC RECEIPT OF OMAHA PUBLIC POWER DISTRICT RESPONSE TO GENERIC LETTER 2006-03, POTENTIALLY NONCONFORMING HEMYC AND MT FIRE BARRIER CONFIGURATIONS (TAC NO. MD1582)

Dear Mr. Ridenoure:

The Nuclear Regulatory Commission (NRC) acknowledges the receipt of your responses dated June 2 and August 2, 2006 (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML061530476 and ML070850193, respectively), to Generic Letter 2006-03, Potentially Nonconforming Hemyc and MT Fire Barrier Configurations. Under oath or affirmation, you have stated that your nuclear power plant does not rely on either the Hemyc or MT fire barrier system. You have submitted documentation under oath or affirmation that other 1 or 3-hour fire barriers that separate redundant safe shutdown trains located within the same fire area have been designed and installed in accordance with current NRC guidance.

Based on your responses, the basis for stating that this other fire barrier has been designed and installed in accordance with NRC guidance should be maintained on site, and will be subject to inspection during the normal NRC inspection process.

If you have any questions regarding this response, please contact me at 301-415-1445.

Sincerely,

/RA/
