| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, states, in part, that, In the case of significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. Contrary to the above, Exelon staff completed corrective actions in response to previously identified pre-conditioning concerns with the collection of the safeguard battery charger TS ST as-found data that was ineffective at precluding reoccurrence of the safeguard battery charger preconditioning. Specifically, the corrective action to revise the safeguard battery charger maintenance procedure did not ensure the as-found current limit setpoint was recorded prior to the cleaning, inspection and potential manipulation of the control circuit cards, which can have a significant impact on the as-found current limit setpoint. This ineffective corrective action lead the site to repeat the potential preconditioning of the safeguard battery chargers for nearly 10 years and called into question whether or not the safeguard battery chargers would perform satisfactorily when in service. Exelon personnel entered the issue into the corrective action program as IR 1478866 and have revised the maintenance procedure to include recording the as-found current limit setpoint prior to any other battery charger manipulation. Because the violation was of very low safety significance (Green) and it was entered into Exelons corrective action program, the violation is being treated as a non-cited violation. |
