Fleming, EsquireSenior Counsel Constellation Generation Group, LLC 750 East Pratt Street, 17th Floor Baltimore, MD 21202 EnclosureREQUEST FOR ADDITIONAL INFORMATIONNINE MILE POINT NUCLEAR STATION, UNIT NO. 2REQUEST FOR RELIEF NO. 2ISI-001By letter dated November 16, 2006, Nine Mile Point Nuclear Station, LLC (the licensee)submitted Request for Relief (RR) No. 2ISI-001 for Nine Mile Point Unit 2 (NMP2) requesting analternative to the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),Section XI, Table IWB-2500-1, Category B-A, Item Number B1.11, reactor pressure vessel (RPV) circumferential shell welds inspection requirements. RR No. 2ISI-001 is for the second 10-year inservice inspection (ISI) interval, in which NMP2 adopted the 1989 Edition of Section XI of the ASME Code, with no addenda, as the ASME Code of record.
Subarticle IWB-2500 of the ASME Code requires components specified in Table IWB-2500-1 to be examined. Table IWB-2500-1 requires volumetric examination of all RPV shell circumferential welds each inspection interval. The licensee is requesting permanent relief from the above ASME Code requirements for theremaining license period and the license renewal period of extended operation for NMP2. The following information is required to complete the Nuclear Regulatory Commission staff's review of RR No. 2ISI-001.In order for the licensee to request relief for the extended operation period, it must also addressBWRVIP-74, "BWR Reactor Pressure Vessel Inspection and Flaw Evaluation Guidelines,"
dated September 21, 1999. The staff's evaluation of BWRVIP-74 was provided by safety evaluation (SE), dated October 18, 2001 (ML012920549). That SE concluded that Appendix E of the staff's July 28, 1998 SE of BWRVIP-05 ("BWR RPV Shell Weld Inspection Recommendations," dated September 1995) conservatively evaluated BWR RPVs to 64 Effective Full Power Years (EFPY), which is 10 EFPY greater than what is realistically expected for the end of an additional 20-year license renewal period. Therefore, the staff's analysis provides a technical basis for relief from the current ISI requirements of ASME Code,Section XI for volumetric examination of circumferential welds as they may apply for the license renewal period. The October 18, 2001, SE further stated that, to obtain relief, each licensee will have to demonstrate:That, at the end of the renewal period, the circumferential welds will satisfy the limitingconditional failure probabilities for circumferential welds in Appendix E of the staff's July 28, 1998 SE, and that they have implemented operator training and established procedures that limit the frequency of cold overpressure events to the frequency specified in the staff's July 28, 1998 SE.
