Request for additional information, North Anna Power Station, Unit 2, COLR Cycle 25 Pattern Key Revision 1 - TAC MF7621 By letter dated April 21, 2016, (Agencywide Document Access and Management System (ADAMS)
Accession No. ML16117A261), VIRGINIA ELECTRIC AND POWER COMPANY (the licensee) submitted COLR Cycle 25 Pattern Key Revision 1 for Cycle 25 for North Anna Power Station, Unit No.2.
The U.S. Nuclear Regulatory Commission (NRC) staff reviewed COLR Cycle 25 Pattern Key Revision 1 and determined that an additional information is needed. Generic Letter 88-16 provides guidance to modify Technical Specifications (TS) that have cycle-specific parameter limits that have been developed using NRC approved methodology. The modifications, in part, were to allow these cycle-specific TS parameters to be relocated to licensee controlled Core Operating Limits Report (COLR) and to include a list of the TS parameters relocated to the COLR and their associated methodologies used to establish these TS parameters in the TS. The licensee has adopted Generic Letter 88-16 for use at North Anna Unit 2. Section 5.6.5 of the licensees TS contains a list of many analytical methods used to develop COLR parameters while the COLR only lists a subset of these analytical methods. Please identify those specific analytical methods listed in the TS that were used in the development of COLR parameters for Cycle 25. If there are analytical methods that were not specifically used for Cycle 25, please provide a justification for maintaining them in the TS.
Please submit the response by July 27, 2016.
If you have any questions please contact me at 301-415-2597.
