| Title | Licensee-Identified Violation |
| Description | A licensee-identified finding of very low safety significance (Green) and associated NCV of 10 CFR 50, Appendix B, Criterion V, Procedures, was identified on August 9, 2012. Station personnel performing walk-downs for TI 2515/188 identified that a cart and recorder assembly staged in the Unit 2 main control room for troubleshooting of Intermediate Range Monitor 15 was not installed per the station seismic housekeeping procedure. The finding is more 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). MA-QC-716-026-1001, Seismic Housekeeping, provided instructions to prevent temporarily stored or transient materials from adversely impacting safety-related components required for safe shutdown of the plant or continued decay heat removal during or following a seismic event. Step 4.2.3 of that procedure addressed the potential for the object overturning and stated in sub-step 3 that the projected fall distance for unsecured, stacked items was determined based on the height plus a minimum of 1 foot. Step 4.2.3.4 required stacked items to be secured together and/or relocated a safe distance away from safety-related equipment or components since the potential interaction distances for loose items would be difficult to predict. Step 4.2.3.5 required restraints where safe distances could not be maintained for unstable items. Contrary to the above, the licensee did not implement the requirements of MA-QC-716-026-1001, Seismic Housekeeping, while executing the Intermediate Range Monitor 15 troubleshooting under WO1542900. Specifically, the licensee placed the unsecured cart and recorder assembly too close to the safety-related equipment and did not restrain the assembly as required by the procedure. The licensee entered the issue into CAP as IR 1399135 and immediately placed the recorder on the floor to remove the tipping hazard. |
