Tennessee Valley Authority, Post Office Box 2000, Decatur, Alabama 35609-2000 December 18, 2013 10 CFR 21.21 ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Browns Ferry Nuclear Plant, Unit 3 Renewed Facility Operating License No. DPR-68 NRC Docket No. 50-296
Subject:
Closure of 10 CFR Part 21 Interim Report - General Electric (GE)
Hitachi Nuclear Energy - SBM Type Manual Switch
Reference:
Letter from TVA to NRC, "10 CFR Part 21 Interim Report - General Electric (GE) Hitachi Nuclear Energy - SBM Type Manual Switch," dated September 12, 2013 On September 12, 2013, The Tennessee Valley Authority submitted an interim Title 10 of the Code of Federal Regulations (10 CFR) Part 21 Report (Reference) regarding the SBM Type manual hand switch for the Residual Heat Removal System I Suppression Pool Isolation Valve. The manual hand switch failed to operate as expected (i.e., spring return to center).
The manual hand switch was sent to General Electric (GE) Hitachi Nuclear Energy to determine the cause of the failure.
GE Hitachi Nuclear Energy completed their evaluation of the manual hand switch and determined that the manual hand switch operated as expected and no credible failure exists.
Since the manual hand switch was determined to be not defective, no deviation in a basic component existed and the condition is no longer subject to an evaluation pursuant to 10 CFR Part 21. Therefore, the referenced interim report may be closed with no additional action required.
