WebENGLISH ABSTRACT: A reactor cavity cooling system (RCCS) is used in the PBMR to protect the concrete citadel surrounding the reactor from direct nuclear radiation impingement and heat. The speci ed maximum operating temperature of the concrete structure is 65 ±C for normal operating conditions and 125 ±C for emergency shut-down conditions. Web3.2 Development of RCCS Model Following reactor core are core barrel, coolant channel and reactor pressure vessel (RPV) in radial direction. Reactor cavity which is divided into two parts by hot riser of RCCS is located at the outside of RPV[5]. One part is up-flow region where the air is directly heated by RPV and flows upward.
