HEAT EXCHANGER TEMPERATURE RESPONSE FOR DUTY-CYCLE TRANSIENTS IN THE NGNP/HTE Unprotected event The upset begins with a loss of generator electric load. The control system is assumed to reduce the pre-cooler and intercooler powers by reducing cold side flow rate. The objective is to bring the long-term heat removal rate into balance with the reactor power which should be decreased to move the plant toward a shutdown state. Failure to reduce the power of the coolers will overcool the plant and cause the reactor inlet temperature to drop. This will add reactivity through a negative inlet temperature coefficient and work against bringing the core power down. The inherent neutronic/decay heat power response resulting from fuel and graphite reactivity temperature feedback is shown in Figures 23 and 24.
