| Title | Failure to Implement Surveillance Test Instructions to Prevent Over-Speed of the TDAFW Pump |
| Description | A self-revealing NCV of Technical Specification (TS) 5.4.1, Procedures, was identified for failure to implement surveillance test procedure instructions for starting the Unit 1 TDAFW pump. The failure resulted in an over-speed trip and inoperability of the pump. This finding has been entered into the licensees CAP as condition report (CR) 2009110308. The failure to implement surveillance test procedure instructions for starting the Unit 1 TDAFW pump was a performance deficiency. This finding was greater than minor because it adversely affected the equipment performance attribute of the mitigating systems cornerstone objective to ensure the availability, reliability and capability of systems responding to initiating events to prevent undesirable consequences (i.e., core damage). This finding was assessed using the Phase 1 screening worksheet of the SDP and determined to be of very low safety significance (Green) because it did not result in an actual loss of safety function of a single train for greater than the TS allowed outage time, and was not potentially risk-significant due to external events. The inspectors identified a cross-cutting aspect in the human performance area of work practices (H.4(b)). The licensee established procedure instructions requiring both steam supplies to the TDAFW pump be opened simultaneously to prevent overspeeding the pump, however, personnel did not follow those procedures |
