| Title | Tsc Temporarily Out of Service for Planned Maintenance |
| Event Description | The Technical Support Center (TSC) fire protection sprinkler system was isolated and tagged out to perform planned maintenance. In conjunction with the sprinkler system being isolated, the charcoal filtered fan unit for the TSC ventilation was isolated. This prevents placing the TSC ventilation system in 'incident' mode; that is, the air cannot be re-directed through the charcoal filter in an event requiring the TSC atmosphere to be filtered due to an on-site release. The TSC ventilation system remains in service providing proper temperature control to maintain the facility habitable during normal operation; however with the 'incident' mode being unavailable, it may not remain habitable during all postulated scenarios and is, therefore, considered non-functional.
The licensee notified the NRC Resident Inspector and will notify the Public Service Commission. |
