| Title | Failure to Evaluate the Affects of a Spurious Safety Injection Signal 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.(1) requires that during postfire shutdown, the fission product boundary integrity shall not be affected; i.e., there shall be no rupture of any primary coolant boundary. Contrary to the above, on July 23, 2009, the NRC identified that FENOC did not meet this requirement and failed to ensure that the RCS SRVs would remain closed if a single spurious operation of the SI signal were to occur during a postfire shutdown. 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. |
