| Title | Failure to Perform a TS Required Battery Performance Test |
| Description | The team identified a finding of very low safety significance (Green) involving a non-cited violation of Salem Unit 1 Technical Specification (TS) Surveillance Requirement (SR) 4.8.2.5.2.h. Specifically, the team identified that PSEG did not perform a battery capacity test of the 1B 28VDC battery within 12 months of the previous performance test that showed signs of degradation (battery capacity as measured on October 28, 2008, dropped more than 10 percent compared to the April 26, 2004, performance test). PSEG promptly entered TS 4.0.3 and completed all TS 4.0.3 requirements for a surveillance not performed within its specified frequency. Additionally PSEG entered the issue into their corrective action program to evaluate the casual factors for long-term corrective action and scheduled the 1B 28VDC battery performance test during the next scheduled Salem Unit 1 shutdown. The finding is more than minor because it is associated with the human 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. Specifically, the availability of the 1B 28VDC battery was not ensured by performing additional surveillance testing to monitor for battery degradation. The team evaluated the finding in accordance with IMC 0609, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 4a for the Mitigating Systems Cornerstone. The team determined that the finding was of very low safety significance because it was a qualification deficiency confirmed not to result in loss of operability. The team determined that this finding has a cross-cutting aspect in the area of Human Performance, Work Practices Component, because PSEG personnel did not follow procedure requirements during the 1B 28VDC battery performance discharge surveillance test. Specifically, personnel did not follow step 5.12.21 of SC.MD-FT.28D-0003 which required technicians to mark the surveillance data sheet Yes for Battery Degraded, notify supervision, and initiate a corrective action notification if the calculated battery performance capacity drop was greater than 10 percent.
