VerDate Aug<31>2005 16:50 Mar 18, 2008 Jkt 214001 [Docket No. 50–395] South Carolina Electric & Gas Company; Virgil C. Summer Nuclear Station, Unit No. 1; Exemption 1.0 Background The South Carolina Electric & Gas Company (SCE&G, the licensee) is the holder of the Renewed Facility Operating License No. NPF–12 which authorizes operation of the Virgil C. Summer Nuclear Station, Unit No. 1 (VCSNS). The license provides, among other things, that the facility is subject to all rules, regulations, and orders of the Nuclear Regulatory Commission (NRC or the Commission) now or hereafter in effect. The facility consists of a pressurizedwater reactor located in Fairfield County in South Carolina. 2.0 Request/Action Pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Section 50.12, ‘‘Specific Exemptions,’’ SCE&G has, by letters dated May 31 and October 11, 2007, requested an exemption from 10 CFR 50.46, ‘‘Acceptance Criteria for Emergency Core Cooling Systems for Light-Water Nuclear Power Reactors,’’ and Appendix K to 10 CFR 50, ‘‘ECCS Evaluation Models,’’ (Appendix K). The regulation in 10 CFR 50.46 contains acceptance criteria for emergency core cooling system (ECCS) for reactors fueled with zircaloy or ZIRLOTM cladding. In addition, Appendix K requires that the Baker-Just equation be used to predict the rates of energy release, hydrogen concentration, and cladding oxidation from the metal-water reaction. The exemption request relates solely to the specific types of cladding material specified in these regulations. As written, the regulations presume the use of zircaloy or ZIRLOTM fuel rod cladding. Thus, an exemption from the requirements of 10 CFR 50.46, and Appendix K is needed to irradiate a lead test assembly (LTA) comprised of different cladding alloys at VCSNS. The exemptions requested by the licensee would allow the use of one LTA containing either all Optimized ZIRLOTM fuel rod cladding or a combination of Optimized ZIRLOTM and PO 00000 Frm 00085 Fmt 4703 Sfmt 4703 14853 AXIOMTM fuel rod cladding to continue to be irradiated up to a burnup of 75 gigawatt days per metric ton uranium (GWd/MTU). Previously, by letter dated January 14, 2005, the NRC staff approved the irradiation of four LTAs containing fuel rods with Optimized ZIRLOTM and several different developmental clad (AXIOMTM) alloys. That exemption was contingent on the fuel rod burnup remaining within the applicable licensed limits, which for burnup, was a value of 62 GWd/MTU. The licensee inserted those LTAs into VCSNS for irradiation in fuel cycles 16 and 17. In the licensee’s letters of May 31 and October 11, 2007, the licensee requested an exemption to continue the irradiation of one of the four LTAs for a third operating cycle. This LTA would be irradiated in fuel cycle 18 in order to gain high burnup experience. The licensee requested to irradiate the LTA to a peak rod average of up to 75 GWd/ MTU. The licensee also requested an exemption from 10 CFR 50.44, ‘‘Combustible gas control for nuclear power reactors.’’ The requested exemption from 10 CFR 50.44 is not being considered further by the NRC staff because revisions were made to 10 CFR 50.44 (68 FR 54123; September 16, 2003), such that it does not refer to specific types of zirconium cladding, thus removing the need for such an exemption. 3.0 Discussion Pursuant to 10 CFR 50.12, the Commission may, upon application by any interested person or upon its own initiative, grant exemptions from the requirements of 10 CFR Part 50, when (1) the exemptions are authorized by law, will not present an undue risk to public health or safety, and are consistent with the common defense and security; and (2) when special circumstances are present. Under Section 50.12(a)(2) of 10 CFR, special circumstances include, among other things, when application of the specific regulation in the particular circumstance would not serve, or is not necessary to achieve, the underlying purpose of the rule. Authorized by Law This exemption would allow the licensee to re-insert one LTA containing either all Optimized ZIRLOTM fuel rod cladding or a combination of Optimized ZIRLOTM and AXIOMTM fuel rod cladding that does not meet the definition of Zircaloy or ZIRLOTM as specified by 10 CFR 50.46, and Appendix K, into the core of VCSNS E:\FR\FM\19MRN1.SGM 19MRN1
