In a telephone conference call on May 15, 2008, the NRC staff communicated a concern with the License Renewal scoping boundary defined in the LRA for equipment in the Prairie lsland Substation. The boundary defined in the LRA is the jurisdictional boundary between plant equipment and non-plant transmission system equipment. The staff indicated that the scoping boundary would be required to encompass certain non- plant transmission system busses and breakers to comply with draft License Renewal Interim Staff Guidance LR-ISG-2008-01, "Staff Guidance Regarding the Station Blackout Rule (10 CFR 50.63) Associated With License Renewal Applications," published in the Federal Register for public comment on March 12, 2008 (73FR13258). | Commrtted to Nuclear Excellence Prairie lsland Nuclear Generating Plant Operated by Nuclear Management Company, LLC May 16,2008 L-PI-08-043 10 CFR Part 54 U S Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Prairie lsland Nuclear Generating Plant Units 1 and 2 Dockets 50-282 and 50-306 License Nos.
