| Title | Evaluate Tsc Operability During Time With Damper Disconnected |
| Description | The inspectors reviewed CAP 01110686 that documented that operators found an actuating rod for a TSC emergency ventilation damper disconnected. The actuator had been disconnected without procedural guidance. With the actuator disconnected, the damper would not function as designed. The actuating rod was connected following initiation of the CAP. While the licensee identified the issue with a TSC ventilation damper, the licensee failed to evaluate the issue for past operability and regulatory impact until questioned by NRC inspectors. Once the licensee recognized the need to evaluate this issue, the inspectors noted inconsistencies between the information provided by various licensee departments, particularly Emergency Preparedness, Engineer and Licensing. Furthermore, these inconsistencies indicated shortcoming in the licensees management oversight associated with this issue. Therefore, this issue is considered an unresolved item (URI) pending the inspectors review of the operability of the TSC while the damper was disconnected.
