| Title | Inoperable Control Room Ventilation System due to Damper Mispositioning |
| Description | The inspectors identified a Green NCV of Technical Specification (TS) 3.7.10 because Entergy personnel did not ensure proper configuration control of a damper in the control room ventilation system (CRVS), which resulted in both trains of CRVS being inoperable for greater than the TS allowed outage time. Although the closed damper was identified by the licensee during planned testing to fulfill Surveillance Requirement (SR) 3.7.10.4, this finding is being considered an NRC-identified finding due to significant questions from the inspectors that resulted in the implementation of additional corrective actions. Entergy personnel entered this issue into their Corrective Action Program (CAP) as CR-IP2-201 0-03076 and CR-IP2-201 0-03564 for resolution. Planned corrective actions included reinforcement of human performance tools, utilization of operating experience during future pre-job and pre-outage briefings, revised system check-off list, and implementation of a more robust method for locking the damper in position. This finding was greater than minor because it was associated with the Barrier Performance attribute of the Barrier Integrity cornerstone, and it impacted the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. This finding is of very low safety significance because it impacted the radiological barrier function of the control room but did not impact other barrier functions of the control room. The inspectors determined that the finding has a cross-cutting aspect in the area of Human Performance, Work Practices component, because Entergy personnel did not ensure that human error prevention techniques were applied to ensure work activities on the \\\'A\\\' CRVS damper did not impact the nearby CCRB1 damper. |
