Abstract:

This document reviews the design status of the SP-100, heat pipe space nuclear reactor system. It also identifies those systems and components requiring additional research to support continued SP-100 system development. The heat pipe reactor was designed to produce 100 KWe of continuous power in a space environment. The design constraints include an expected system operation time of 7 years and a maximum weight of approx. 3000 kg. The reactor, employing an unclad, highly enriched uranium dioxide core, operates as a fast reactor, and is cooled by high temperature molybdenum -- 13 percent rhenium, heat pipes with lithium working fluid. Electric power is generated by thermoelectric converters, with the bulk of the thermal energy rejected to space by a radiator panel system. Keywords Space nuclear reactor Radiation shield Thermoelectric converter Heat pipe Radiator Nuclear fuel Fuel waters Control drums Self- welding Thermal radiation Fuel swelling Lithium coolant Gamma fission products Power upgrade Uranium dioxide fuel.
