A self-revealing NCV of Unit 1 TS 6.8, Pro … A self-revealing NCV of Unit 1 TS 6.8, Procedures & Programs, was identified for the licensees failure to provide adequate procedures for a maintenance activity involving the required inspection of an Essential Raw Cooling Water (ERCW) pipe leak in the Unit 1 Turbine Driven Auxiliary Feedwater Pump (TDAFW) room. This resulted in water intrusion into the governor control cabinet of the TDAFW Pump, which caused the pump to be inoperable due to an electrical overspeed trip caused by fluctuating speed indications. This issue was entered into the licensees corrective action program as Problem Evaluation Report (PER) 470310. The performance deficiency was determined to be more than minor because it was associated with the procedure quality attribute of the mitigating systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the Unit 1 TDAFW pump was made inoperable due to water intrusion into an AFW control system cabinet. Using Inspection IMC 0609, Significance Determination Process, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance (Green) since it did not represent an actual loss of safety function of a single train for greater than the associated TS allowed outage time. The finding was determined to have a crosscutting aspect in the Work Control component of the Human Performance cross-cutting area since the licensee failed to appropriately plan and coordinate work activities, consistent with nuclear safety.rk activities, consistent with nuclear safety. +
