For several years design studies have been under way in the US on high-temperature process heat and steam applications utilizing a high-temperature gas-cooled reactor (HTGR) plant. Plant designs have incorporated safety-class core auxiliary cooling systems (CACSs). Each CACS primary loop includes an auxiliary helium circulator, a shutoff valve, and a water-cooled core auxiliary heat exchanger (CAHE), which transfers heat from the primary coolant helium to secondary system water. This function may be for normal or plant accident conditions and is completely independent of the main heat exchanger loops. The cooling modes include pressurized cooldown, depressurized cooldown, and cooldown for maintenance, refueling, and tests. The design criteria, design configuration, performance, and safety aspects of the CAHE design are presented.
