Many of the advantages mentioned for outage control centres also apply to the EOF and the TSC. The EOF is normally outside the perimeter of the power plant and it serves as the management and coordination centre for the emergency staff that will operate from there in the event of an emergency at the plant. Advanced HSIs will help to manage information about important plant parameters and radiological conditions in the plant and its immediate surroundings.

The TSC is an on-site facility located close to the control room — according to NUREG-0696 (1981), the TSC must be located within a two-minute walk of the main control room. During upset and emergency conditions it provides technical support to plant management and the reactor operating personnel located in the control room. Advanced HSIs with diagnostic features will be important here too to help TSC personnel analyse the plant conditions before and throughout the course of an accident.
