- Fort Calhoun Station Amendment Description TAC No.
FCS No.
Implementation Date N/A In accordance with NRC letter dated July MD4534 12/31/07.
26, 2007, (NRC-07-0073) a new license condition capturing the interim compensatory measures (ICM) Order (EA-02-026) Section B.5.b mitigation strategy requirements was incorporated into the licensing basis.
250 The amendment deleted the Technical MD3854 10/04/07 Specification (TS) requirements associated with the hydrogen purge system. The change is consistent with revisions of Section 50.44 of Title 10 of the Code of Federal Regulations, "Combustible Gas Control for Nuclear Power Reactors," that became effective on. October 16, 2003. This operating license improvement was made available by the NRC on September 25, 2003 (68 FR 55416) as part of the consolidated line item improvement process (CLIIP).
251 The amendment revised TSs 2.7(1),
MD6221 05/24/08 2.7(2), and TS 3.7(5), to allow the addition of two safety-related swing inverters to the 120-volt alternating current instrument buses. The TS changes take advantage of the additional operational flexibility provided by the swing inverters.
LIC-08-0080 Attachment Page 2 Amendment Description TAC No.
FCS No.
Implementation Date 252 The amendment revised the TS safety MD6808 05/23/08 limit (SL) requirements related to the use of a non-cycle specific peak linear heat rate SL of 22 kilowatt hours per foot (kW/ft) to fuel centerline melt. The change is consistent with the objective of TS Task Force (TSTF) 445-A, Revision 1, which determined that the current SL does not clearly conform to paragraph 50.36(d)(1 )(ii)(A) of Title 10 of the Code of Federal Regulations.
253 The amendment removed the footnote to MD6704 05/20/08 TS 2.3(4) and TS 3.6(2)d, limiting the use of sodium tetraborate to Operating Cycle 24 only. In addition, TS 2.3, Figure 2-3 was revised to increase the volume of sodium tetraborate due to the selection of a different chemical vendor and an increase in mass to provide additional pH margin.
254 The amendment revised emergency MD6939 06/06/08 diesel generator,(DG) surveillance testing in TS 3.7, to support modification of the DG start circuitry. Prior to the amendment, TS 3.7 required verification of the anticipatory DG start-to-idle speed upon a reactor trip. The amendment deleted the anticipatory DG starting requirement. This amendment also deleted a footnote to TS 3.7(1)e pertaining to a one-time extension of the surveillance interval for DG-1 that was granted in Amendment No. 112.
LIC-08-0080 Attachment Page 3 Amendment Description TAC No.
FCS No.
Implementation Date 255 The amendment revised TSs 2.4, 2.14, MD6204 06/03/08 2.15, 3.1, 3.5(4), 3.6(3), and associated MD7043 TS Basis documents and Updated Safety Analysis Report sections to modify the containment spray system actuation logic to preclude automatic start of the containment spray pumps for a loss-of-coolant accident. The amendment also revised TS 3.6(3)a to delete a surveillance requirement (SR) for testing of the containment air cooling and filtering system emergency mode dampers and replaced it with a SR to verify that the dampers are in their accident positions in all operating plant modes. The SR in TS 3.6(3)b to remotely operate the dampers was deleted. The amendment added license conditions related to the replacement and testing of containment air cleaning and filtering (CACF) unit HEPA (high-efficiency particulate air) filters and surveillance testing of the CACF unit relief ports.
256 The amendment revised TS 2.1.1 and the MD6993 05/18/08 SR of TS 3.1.6 to increase the shutdown cooling (SDC) system entry temperature from 300°F to 350°F (cold leg), and the SDC entry pressure from 250 pounds per square inch absolute (psia) to 300 psia (indicated at the pressurizer).
