The three-loop power system which is to be used with Experimental Breeder Reactor No. II (EBR-II) was analyzed to determine the coolant flow rate requirements at various power levels, coolant temperatures at various power levels, effects of heat exchanger sizes (system optimization), and effects of control errors. An intermediate heat exchanger, preheater, evaporator, and superheater are included in the EBR-II power system. Constant thermal resistances and physical properties, and perfect insulation were assumed in the analysis. Among other things, the study showed that at low power levels, excessive thermal stresses are produced at the cold end of the intermediate heat exchanger ualess a high sink temperature is used. It was also found that a short cut may be used to determine approximate system conditions at all power levels, that system optimization requires compromises, and that system flow rate control is possible through high-low measurements of two coolant temperatures in the primary system.
