The NEP spacecraft design is for the 100 kWe SP-100 nuclear reactor thermoelectric power supply. Thermoelectric conversion, one of several conversion options being considered for the SP-100, is discussed. Whereas many of the earlier NEP spacecraft designs have been based on highly integrated power and thruster subsystems and have resulted in subsystem requirements that depended largely on the design mission, the SP-100 nuclear power system is a general-purpose power supply. The configuration design must be compatible with this power subsystem design philosophy. The study also detects power and propulsion subsystem integration issues and related technology requirements. It is noted that the new NEP spacecraft design satisfies the most important subsystem integration requirements at the expense of some increase in vehicle inert mass relative to that used in previous studies.
