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. 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
WebCanada has attracted specific interest from developers of nonwater-cooled small modular reactor (SMR) technologies, including concepts based on high-temperature gas-cooled reactors (HTGRs). It is anticipated that some research and development (R&D) will be necessary to support safety analysis and licensing of these reactors in Canada. The … WebA Reactor Cavity Cooling System (RCCS) is equipped in RDE, functions as heat removal system. Heat transferred from the reactor vessel is removed to the environment so that the reactor wall does not overheat. The RCCS is installed in the cavity between the reactor vessel and the concrete structure. It is designed to maintain the
