Revision to the Generic Letter 89-10, Safety-related Motor-operated Valve, Scope

- 1. Letter from TVA to NRC, "Browns Ferry Nuclear Plant (BFN) - Units 2 and 3 - Generic Letter (GL) 89-10, Safety-related Motor-operated Valve (MOV) Testing and Surveillance, NRC Inspector Followup Item (IFI) 50-260, 296/95-19-01, Response to Request for Reevaluation Regarding Reduced scope of MOVs," dated January 6, 1997
Generic Letter 89-10 and Supplements 1 to 7, Safety-related Motor-operated Valve (MOV) Testing and Surveillance," dated May 5, 2004 In a letter dated January 6, 1997 (Reference 1), the Tennessee Valley Authority (TVA) submitted a letter that provided a reevaluation of the safety functions of certain motor-operated valves (MOVs) that were removed from or not included in the Browns Ferry Nuclear Plant (BFN) Generic Letter (GL) 89-10 program for BFN, Units 2 and 3. Based on the reevaluation performed by TVA, certain MOVs were added to the GL 89-10 program.
However, other MOVs that were normally in their safety position were not added to the GL 89-10 program for BFN, Units 2 and 3. For these MOVs, a commitment was made to revise plant procedures to require that the affected system, or train for the MOVs that were not added to the GL 89-10 program be declared inoperable when the MOVs were taken out of their normal safety position for testing.
TVA submitted a letter dated May 5, 2004 (Reference 2) that provided an updated response to GL 89-10 for BFN, Unit 1. Based on this updated response to GL 89-10 program, BFN, Unit 1, included the same scope of the GL 89-10 program as the BFN, Units 2 and 3, GL 89-10 program.

U.S. Nuclear Regulatory Commission Page 2 January 31, 2013 As part of extent of condition reviews associated with the failure of valve 1-FCV-74-66, discovered on October 23, 2010, the scope of the GL 89-10 program for BFN has been reevaluated. The purpose of this letter is to revise the scope of the GL 89-10 program for BFN to include the additional valves identified during this reevaluation. The Enclosure provides a list of MOVs that have been added to the GL 89-10 program for BFN.
The Enclosure provides a summary of commitments contained in this letter and a projected schedule for their completion. Should you have any questions concerning this submittal, please contact J. E. Emens, Jr., Nuclear Site Licensing Manager, at (256) 729-2636.
