Title | Licensee-Identified Violation |
Description | Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to this requirement, on May 10 and May 12, 2011, the licensee failed to accomplish an activity affecting quality as prescribed by the documented procedure. Specifically, the licensee failed to perform operability reviews when heat trace circuit 1-8C fell below the operating instruction temperature on the steam supply piping to the emergency feedwater pump in accordance with Procedure EN-OP-104, Operability Determination Process. The team determined that this finding was of very low safety significance (Green) because it affected the design or qualification of a mitigating system structure component; however, the system structure component maintained its operability. The emergency feed water pump AB was declared inoperable on May 14, 2011; however, subsequent evaluation declared the pump operable but degraded. This was documented in the licensees corrective action program as Condition Reports CR-WF3-2011-03599 and CR-WF3-2011-03600. |
