| Title | Pressure Boundary Leakage Caused by Primary Water Stress Corrosion Cracking |
| Description | Ginna Operating License Condition 2.C.(3), Fire Protection Program, in part, required Constellation to implement and maintain in effect all fire protection features described in licensee submittals referenced in and as approved or modified by the NRC's SER, dated February 1979, and subsequent supplements. ND-FPP, Fire Protection Program, in part, stated that EPM-FPPR-ANL, Fire Protection Program Report, was utilized to implement the fire protection program requirements approved by the NRC SER. EPM-FPPR-ANL Volume 3, Part lV, Section 4.2.1, in part, stated that for each safe shutdown system, the primary flow paths and operational characteristics that must be established to accomplish the desired safe shutdown performance goal were identified, as well as the components that established the primary safe shutdown flow path and/or system operation. Contrary to the above, on September 21,2012, the NRC identified that Constellation did not identify the VCT flow path to the A charging pump was part of the RCS makeup flow path, and did not identify the operational characteristics that must be established to accomplish the desired safe shutdown performance goal of this flow path. Specifically, Constellation did not identify that the VCT remained connected to the charging pump (through the VCT outlet valve) in parallel with the RWST during alternative shutdown activities. Further, Constellation did not evaluate the impact of the VCT, which was normally pressurized with Hz gas, on the safe shutdown performance goal of that flow path. The violation was historical and occurred when Ginna completed its first safe shutdown analysis. Constellation was in transition to NFPA 805 and, therefore, this NRC-identified violation was evaluated in accordance with the criteria established in Section 9.1 of the NRC's Enforcement Policy regarding Enforcement Discretion for Certain Fire Protection lssues (10 CFR Part 50.48). Because all the criteria were met, the NRC exercised enforcement discretion for this issue. |
