| Title | Failure to Adequately Ensure Cable Protection and Eliminate Potential Secondary Fires |
| Description | Calvert Cliffs Nuclear Power Plant Operating License conditions 2.E. for both Unit 1 and Unit 2, require that Calvert Cliffs Nuclear Power Plant, LLC, shall implement and maintain in effect all provisions of the approved fire protection program as described in the approved fire protection program (FPP) as described in the Updated Final Safety Analysis Report (UFSAR). UFSAR Section 9.9.1 states in part that the FPP has been developed in accordance with the documents listed in Section 9.9.12 (References 1 through 19). References 4 and 5 are the Interactive Cable Analysis (ICA) for Calvert Cliffs Nuclear Power Plant Unit 1 and Unit 2 respectively. Assumption 5 in the ICA Manual for Units 1 and 2 states: If a fire causes electrical shorts or overloads, protective devices are assumed to function properly except as affected by the postulated fire. Contrary to the above, on June 18, 2013, Constellation identified seven Unit 1 cables and three Unit 2 cables which were not coordinated, i.e. the cables were undersized and could overheat due to fire induced faults causing secondary fires. The cables traversed multiple fire areas where secondary fires could render additional redundant or alternate safe shutdown equipment unavailable. The violation was historical and occurred when Calvert Cliffs completed its first safe shutdown analysis. Constellation is in transition to NFPA 805 and, therefore, this licensee-identified violation was evaluated in accordance with the criteria established in Section 9.1 of the NRC Enforcement Policy, Enforcement Discretion for Certain Fire Protection issues (10 CFR 50.48). Specifically, because all of the criteria were met, the NRC is exercising discretion and not issuing a violation for this issue. |
