| Description | Hatch Renewed OLCs 2.C.(3) and 2.C.(3)(a), for Units 1 and 2 respectively, state, in part, that Southern Nuclear shall implement and maintain in effect all provisions of the fire protection program, which is referenced in the Updated Final Safety Analysis Report for the facility, as contained in the updated Fire Hazards Analysis and Fire Protection Program for the Edwin I. Hatch Nuclear Plant, Units 1 and 2, which was originally submitted by letter dated July 22, 1986.Section IV.C.5, Carbon Dioxide Suppression Systems, of Appendix D of the FHA states, in part, that the computer room design concentrations are in compliance with NFPA Standard No. 12, Section 2421, which requires a 50-percent concentration for dry electrical, wiring insulation hazards in general . NFPA 12 states, in part, that an acceptable CO2 system deliver and hold a minimum gas concentration of 50 percent in the protected area. Contrary to the above, the CO2 system design concentration in the computer room is not in compliance with the Hatch FHA, in that the CO2 system would not deliver and hold a minimum gas concentration of 50 percent in the protected area. The violation has existed since initial plant start-up. The licensee entered the deficiency in the CAP as CR 736771. Because the licensee committed to adopt NFPA 805 and change their fire protection licensing bases to comply with 10 CFR 50.48(c), the NRC is exercising enforcement and reactor oversight process (ROP) discretion for this issue in accordance with the NRC Enforcement Policy, Section 9.1, Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48) and Inspection Manual Chapter 0305. Specifically, this issue was identified and will be addressed during the licensees transition to NFPA 805, was entered into the licensees corrective action program, immediate corrective action and compensatory measures were taken, was not likely to have been previously identified by routine licensee efforts, was not willful, and it was not associated with a finding of high safety significance. |
