The SP-100 program develops, validates, and demonstrates the technology for space nuclear power systems in the range of 10 to 1000 kilowatts electric for use in future military and civilian space missions.
SP-100 reactor for lunar surface power system applications. Two designs were characterized and modeled. The first design integrates a 100-kWe SP-100 Brayton power system with a lunar lan-der. This system is intended to meet early lunar mission power needs while minimizing on-site installation requirements.
1 Φεβ 1989 · The design concept consists of a 2500 kWt (kilowatt thermal) SP-100 reactor coupled to eight free-piston Stirling engines. Two of the engines are held in reserve to provide conversion...
Of particular interest are methods for achieving thaw within the reactor vessel, means for thawing progressively along piping and within components, and assuring fluid communication of molten zones with free expansion spaces to avoid structural damage.
An update on the SP-100 reactor subsystem design and performance is provided. Several key requirements have influenced the design substantially as the more detailed nuclear, thermal/hydraulic, and structural analyses have been completed for the various mission phases including accident safety performance characteristics.
The NASA, DOD, and DOE triagency SP-100 Pro- gram has recently embarked on a major effort to demonstrate the technology readiness of nuclear reactor space power systems for space applications by 1992. This program is termed the SP-100 ground engineerin system (GES) in which system safety and typica? reactor and aerospace (conversion,
SP-100 (Space reactor Prototype [1]) was a U.S. research program for nuclear fission reactors usable as small fission power systems for spacecraft. [2] It was started in 1983 by NASA , the US Department of Energy and other agencies.
