| Title | Containment Overpressure Not Ensured in the Appendix R Analysis |
| Description | The licensee issued Licensee Event Reports (LER 05000263-2009-001-00 and LER 05000263-2009-001-01) regarding the licensees failure to consider the spurious opening and venting of the primary containment, via purge and vent valves, in the event of a fire in the main control room or cable spreading room. Both LER revisions were closed in Inspection Report 05000263/2009004 and documented as a violation of NRC requirements. Because the licensee was transitioning to NFPA 805 and the violation met the criteria established by the NRC Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR Part 50.48(c)) for licensee in NFPA 805 transition, the NRC exercised enforcement discretion to not cite the violation in accordance with the NRCs Enforcement Policy. On December 22, 2010, the licensee provided an update to LER 05000263-2009-001-02 to reflect their withdrawal of the letter of intent to voluntarily implement 10 CFR 50.48(c) at the MNGP. On May 14, 2009, the NRC issued EGM 09-002, Enforcement Discretion for Fire Induced Circuit Faults, dated May 14, 2009, which authorized enforcement discretion for non-compliance issues associated with fire induced multiple circuit cable faults, providing that the licensee identified the non-compliances, entered them into their CAPs, and instituted appropriated compensatory measures until the issues were corrected, within the six month period following a planned revision to RG 1.189, Fire Protection for Nuclear Power Plants. Regulatory Guide 1.189, Revision 2, issued in October 2009, provided a method acceptable to the NRC to evaluate and resolve multiple fire induced circuit faults. After the six month period designated for the identification of non-compliances, the EGM further authorized enforcement discretion for an additional 30 month period, for licensees to resolve the identified multiple fire-induced circuit fault issues. The inspectors screened this violation and determined that because the violation was associated with multiple fire induced circuit faults and was identified during the discretion period as described in EGM 09-002, the NRC is exercising enforcement discretion for this violation in accordance with EGM 09-002. |
