| Title | Failure to Implement Procedures Used to Prevent Seismic Interaction with Safety-Related Equipment |
| Description | A self-revealing finding was identified for a failure to implement procedures to ensure that temporary equipment carts were immobilized in order to prevent inadvertent contact with safety related equipment. Specifically, the Unit 1 H bus protective relay cabinet resulting in inoperability of the 1C Emergency Diesel Generator (EDG). This finding was entered into the licensees CAP as CR 2009101710. Failure to implement a procedure to ensure temporary equipment carts were immobilized to prevent inadvertent contact with the Unit 1 H bus protective relay cabinet was a performance deficiency. This finding was greater than minor because it adversely affected the equipment reliability 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. The finding did not involve a total loss of any safety function, as identified by the licensee through a Probabilistic Risk Assessment (PRA), Individual Plan Examination of External Events (IPEEE), or similar analysis, contributing to external event-initiated core damage accident sequences (i.e., initiated by a seismic, flooding, or severe weather event). The inspectors identified a cross-cutting aspect in the human performance area of work practices component (H.4(b)). The licensee had established a procedure requiring all wheeled items left in safety-related areas be made incapable of rolling and personnel did not follow the procedure. The procedure the licensee failed to implement was not safety related, therefore, the performance deficiency did not result in a violation of regulatory requirements. |
