A finding of very low safety significance … A finding of very low safety significance (Green) and an associated NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors when licensee personnel failed to adhere to Surveillance Procedure BwHS 4002-012, Revision 9, AF (Auxiliary Feedwater) Nickel Cadmium Battery Surveillance. Specifically, the licensee failed to identify open spaces between the wooden shim blocks and the end of the battery rack for the diesel-driven AF pump batteries. The licensee entered this issue into the CAP as IR 1379674 and planned to replace the shim blocks. The inspectors determined that the failure to follow the surveillance procedure was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the licensee failed to ensure that batteries were restrained from sliding along the rack to avoid over-stressing the end or base of the racks as specified in the seismic qualification document. The finding was determined to be of very low safety significance (Green) because it was a design or qualification deficiency confirmed not to result in a loss of operability or functionality. This finding had a cross-cutting aspect in the Work Practices component of the Human Performance cross-cutting area (H.4(b)) because the licensee failed to effectively communicate the expectation and the bases regarding the acceptance criteria of the surveillance procedure.ce criteria of the surveillance procedure. +
