FORT CALHOUN STATION, UNIT NO. 1 - WITHDRAWAL OF ANAMENDMENT REQUEST (TAC NO. MC8093)

Dear Mr. Ridenoure:

By letter to the Nuclear Regulatory Commission (NRC) dated August 11, 2005, assupplemented by letter dated November 3, 2005, Omaha Public Power District (OPPD/the licensee) applied for an amendment to the Fort Calhoun Station, Unit No. 1 (FCS), Facility Operating License No. DPR-40. The proposed change would have revised the FCS's Technical Specifications (TS) pertaining to the volume of trisodium phosphate (TSP) needed in containment. Specifically, this proposed change would have revised TS Figure 2-3, "TSP Volume Required for RCS Critical Boron Concentration (ARO, HZP, No Xenon)," and related technical information used for calculating minimum volumes of TSP required for maintaining sump pH equal to or greater than 7. By amendment request dated August 21, 2006, OPPD requested to change the containmentbuffering agent from TSP to sodium tetraborate. By letter dated November 13, 2006, the NRC staff approved this change. As a result of this approval, TSP is no longer used in the containment at the FCS. As such the amendment is no longer needed at this time and by letter dated November 30, 2006, OPPD withdrew the amendment request. The Commission has filed the enclosed Notice of Withdrawal of Application for Amendment toFacility Operating License with the Office of the Federal Register for publication.Sincerely,/RA/Alan B. Wang, Project ManagerPlant Licensing Branch IV Division of Operating Reactor Licensing Office of Nuclear Reactor RegulationDocket No. 50-285

The proposed amendment would have revised the Technical Specifications (TSs)pertaining to the volume of trisodium phosphate (TSP) needed in containment. Specifically, this proposed change would have revised TS Figure 2-3, "TSP Volume Required for RCS [Reactor Coolant System] Critical Boron Concentration (ARO [All Rods Out], HZP [Hot Zero Power], No Xenon)," and related technical information used for calculating minimum volumes of TSP required for maintaining sump pH equal to or greater than 7. The amendment was necessary to account for the increase in the RCS volume as result of the planned replacement of the steam generators and pressurizer. The amendment is no longer needed since the NRC staff has approved the OPPD amendment dated August 21, 2006, to remove the TSP and replace it with sodium tetraborate. The Commission had previously issued a Notice of Consideration of Issuance ofAmendment published in the FEDERAL REGISTER on September 27, 2005 (70 FR 56502).

However, by letter dated November 30, 2006, the licensee withdrew the proposed change.For further details with respect to this action, see the application for amendment datedAugust 11, 2005, as supplemented by letter dated November 3, 2005, and the licensee's letter dated November 30, 2006, which withdrew the application for license amendment.
