| Title | Malfunctioning Technical Support Center Ventilation |
| Event Description | The facility Technical Support Center (TSC) has been rendered non-functional due to a malfunctioning TSC ventilation system. Investigation into the cause of elevated TSC room temperature led to the discovery of a tripped condensing unit compressor. Repairs to the TSC ventilation system were immediately initiated with high priority.
Compensatory measures per site procedure FNP-0-EIP-6.O (TSC Setup and Activation) for maintaining emergency assessment, off-site response, and off-site communication capabilities were immediately put in place. These measures include the conditional relocation of the TSC staff in the event of a declared emergency if the Emergency Director deems the TSC to be uninhabitable. The licensee will notify the NRC Resident Inspector. |
