Title | Failure to Evaluate the Impact of Spurious Volume Control Tank Outlet Valves Closure During Alternative Shutdown |
Description | Beaver Valley Unit 2 License Condition 2.F requires in part that FENOC shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report (FSAR) through Amendment No. 17, and submittals dated May 18, May 20, May 21, June 24, and July 6, 1987. BVPS Unit 2 FSAR Rev. 17 Section 9.5.1.1 states that the fire protection system is designed using the guidance of BTP CMEB 9.5-1, Rev. 2. BTP CMEB 9.5-1, Rev. 2, Section C.5.c.(7) requires that alternative safe shutdown equipment and systems for each fire area should be known to be isolated from associated circuits in the fire area so that hot shorts, open circuits, or shorts to ground in the associated circuits will not prevent operation of the safe shutdown equipment. Contrary to the above, on August 4, 2009, the NRC identified that FENOC did not meet this requirement and failed to protect the 21A charging pump from a single circuit failure resulting in the spurious closure of the VCT outlet valves. FENOC is in transition to NFPA 805 and therefore the NRC-identified violation was evaluated in accordance with the criteria established by Section A of the NRCs Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR Part 50.48) for a licensee in NFPA 805 transition. Specifically, although the NRC identified the violation, it is likely that FENOC would have identified and corrected this issue as part of the transition to NFPA 805, FENOC entered the issue into the corrective action program, FENOC implemented compensatory measures in a reasonable time commensurate with the risk significance, the issue was not likely to have been previously identified by routine FENOC efforts, and the violation was not willful. Because all the criteria were met, the NRC is exercising enforcement discretion for this issue. |
