| Title | Failure to correctly position EDG room ventilation temperature controllers in automatic |
| Description | The team identified a finding of very low safety significance (Green) involving a non-cited violation of Technical Specification (TS) 5.4, Procedures. Specifically, following EDG maintenance, operators did not restore the A and C EDG ventilation systems in accordance with operating procedure OP-60, Diesel Generator Room Ventilation. In particular, operators failed to correctly position the A and C EDG room ventilation temperature controllers to automatic as required by Entergy procedure OP-60. Following discovery, operators promptly restored controllers to automatic, performed additional extentof- condition control panel walkdowns throughout the plant, and entered the issue into their corrective action program to evaluate and address causal factors. The performance deficiency was determined to be more than minor because it was associated with the Configuration Control 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. The team evaluated the finding in accordance with IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings at Power, Exhibit 2 Mitigating Systems Screening Questions. The team determined that the finding was of very low safety significance because it was not a design qualification deficiency resulting in a loss of functionality or operability and did not represent an actual loss of safety function of a system or train of equipment. The team determined that this finding has a cross-cutting aspect in the area of Human Performance, Work Practices Component, because Entergy did not adequately ensure supervisory and management oversight of EDG ventilation system restoration activities such that nuclear safety was supported. |
