An NRC-identified non-cited violation (NCV … An NRC-identified non-cited violation (NCV) of Technical Specification (TS) 5.4.1 Procedures, was identified with two examples. The licensee failed to implement and maintain surveillance test procedures for surveillance requirements (SR) 3.8.4.4 and SR 3.8.4.2. As a result, the licensee failed to perform actions to satisfy TS surveillance requirements and the battery terminal fasteners corroded and degraded over time. This event was entered into the licensees corrective action program as condition report (CR) 10206961. The licensee conducted the surveillance tests and implemented work order (WO) 777073 to remove visible terminal corrosion, replace corroded termination hardware, and verify battery cell-to-cell and terminal connections were coated with anti-corrosion material. The licensees failure to implement and maintain procedures used to satisfy surveillance requirements for the Unit 1 1B 125VDC auxiliary building battery was a performance deficiency. The performance deficiency was more than minor because, if left uncorrected, it had the potential to result in excessive corrosion buildup on the battery cell-to-cell and terminal connections which could have impacted the ability of the battery to perform its safety-related function. The significance of the finding was of very low safety significance (Green) because it was not a design or qualification deficiency, it did not represent a loss of system safety function of a single train for greater than its Technical Specification allowed outage time, and it did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating events. The inspectors determined the finding had a cross-cutting aspect of Resources in the Human Performance area, because the licensee failed to ensure procedures used to conduct TS surveillance requirements for the 1B 125 VDC auxiliary building battery were adequate and implemented correctly. (H.1) adequate and implemented correctly. (H.1) +
