Request for Additional Information cc w/encl: Distribution via Listserv

REQUEST FOR ADDITIONAL INFORMATION RELATED TO RELIEF REQUEST TO EXTEND THE FOURTH INSERVICE INSPECTION INTERVAL FOR OYSTER CREEK NUCLEAR GENERATING STATION EXELON GENERATING COMPANY, LLC DOCKET NO. 50-219 By letter dated September 30, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML112730210), Exelon Generation Company, LLC (Exelon),

submitted Relief Request R-41 for Oyster Creek Nuclear Generating Station (OCNGS). Relief Request R-41 seeks relief from the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, "Rules for Inservice Inspection of Nuclear Power Plant Components," in accordance with Title 1 a of the Code of Federal Regulations (10 CFR), Section 50.55a, "Codes and standards," paragraph (a)(3)(i). Relief Request R-41 proposes to extend the Inservice Inspection interval by 3 months.

The U.S. Nuclear Regulatory Commission staff is reviewing the submittal dated September 30, 2011, and has determined that additional information is required to complete the review. The specific information requested is below.

REQUEST FOR ADDITIONAL INFORMATION

1. Identify the examinations that still remain to be completed in order to fulfill the 4th 1 a-year inspection interval examination requirements by Examination Category, Item Number and quantity.
2. The ASME Code (IWA-2430(d)(2>> allows the 5th inspection interval examinations to begin in the same outage that the final 4th inspection interval examinations are completed. This could be done without relief from the requirements of IWA-2430. Yet Relief Request R-41 states that the 5th interval will begin at the end of the requested 4th interval extension. Provide a projected schedule for the 5th interval examinations showing when examination periods would begin and end along with projected outage schedules in the examination periods. Justify why delaying the start of the 5th interval provides an acceptable level of quality and safety.
