| Title | Failure to Follow Procedures Renders Safety Related Battery Charger Inoperable |
| Description | A self-revealing NCV of TS 5.4.1.a, Procedures was identified for the licensees failure to properly implement maintenance procedures and work order instructions and inadvertently removed the 2AD1CB safety-related battery charger from service while attempting to perform routine battery surveillance on the 2CD1B battery. Upon discovery, the licensee immediately stopped the work and returned the battery charger to service. The licensee entered the condition into their corrective action program as CR 10002493. The performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective in that the opening of the power supply breaker to the incorrect battery charger (2AD1CB) resulted in the charger being inoperable for a total of 30 minutes. The inspectors evaluated the finding using IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012. Because the inspectors answered No to all of the Exhibit 2, Mitigating Systems Screening Questions, the inspectors concluded that the finding was (Green).The inspectors determined the finding had a cross-cutting aspect of Challenge the Unknown in the Human Performance area because the station operator proceeded in the face of uncertainty. |
