OSTI ID:5493511

The Auxiliary Heat Removal System (AHRS) is an engineered safety system included in the 2240 MW(t) HTGR-SC/C Plant to remove heat from the reactor core and primary coolant whenever heat removal through the main primary coolant loops and steam system is not available and the reactor has been tripped. As its name implies, this system functions as a backup system for the removal of heat from the reactor and thereby maintain plant protection and control of radionuclide release from the core. As designed AHRS consists of three functionally identical heat transport loops. The scope of the system includes the Auxiliary Circulator Subsystem (ACS) and the Auxiliary Heat Exchanger (AHE), both of which interface with the primary, coolant, the Auxiliary Heat Removal Control Subsystem, controlling power to the Auxiliary Circulator, and Auxiliary Cooling Water Subsystem comprising the secondary circuit that transports the heat removed from the AHE to the system ultimate heat sink for the AHRS, which is ambient air, and the Auxiliary Circulator Motor Cooling Subsystem.
