WebRCCS is a passive safety-related system that removes the decay heat of VHTR when normal decay heat removal systems are in failure. Understanding thermo-hydraulics of RCCS is important to design a safer VHTR. RCCS consists of 292 cooling panels, which are placed in the reactor cavity. The layout of RCCS gives an idea WebThe primary functions of the Reactor Cavity Cooling System (RCCS) are to protect the concrete structure surrounding the reactor vessel from overheating during all modes of operation and to provide alternate means of removing reactor heat when neither the Primary Cooling System (PCS) nor the Shutdown Cooling System (SCS) is available.
Webstart-up RCCs do reactivity changes with power level, and the shutdown RCCs do reactivity changes between the cold zero power state and the hot zero power state. Only 12 operation RCCs are inserted in the core during full power operation. Either of these groups can move the reactor from a hot full power to a hot shutdown state. The shutdown
