Özet:

 A variable-temperature heat reservoir endoreversible simple closed Brayton cycle CBC model for space nuclear power plant is established. Thermal efficiency TEF and power output POW are derived. When total heat transfer area of radiator panel and two heat exchangers HEXs is fixed, the maximum POW   is obtained by optimizing area distributions  , and  among two HEXs and radiator panel, the double maximum POW   is obtained by optimizing inlet temperature   of cooling fluid in low temperature heat sink, and the triple maximum POW   is obtained furtherly by optimizing thermal capacity rate matching   between heat reservoir and working fluid. When , and are optimized, increases by 4.33 compare to initial POW  ; when is furtherly optimized, increases by 6.33 compare to and increases 1.86 compare to ; and increases 11.76, 7.13 and 5.17 compare to , and , respectively.
