If an emergency condition occurs that requires activation of the Technical Support Center during this work activity, contingency plans are in place to restore the TSC to fully functional status, with the time to restoration dependent on the stage of the work activity at the time the emergency occurs. Plans are to utilize the Shift Manager's Office in the Control Room as the Backup TSC for any declared emergency during the time the work activity is being performed. Procedure 91201-C, Activation and Operation of the Technical Support Center, provides instructions to direct TSC management to the Control Room to continue TSC activities if it is necessary to relocate from the primary TSC. At the beginning of the TSC outage, the ENN [Emergency Notification Network] and ERDS [Emergency Response Data System] will not be available until temporary power is being provided. This outage for the communications equipment will last from 2-4 hours, at which time they will be available. | If an emergency condition occurs that requires activation of the Technical Support Center during this work activity, contingency plans are in place to restore the TSC to fully functional status, with the time to restoration dependent on the stage of the work activity at the time the emergency occurs.
