SP-100 nuclear power system. 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. [3] A reactor was developed with heat pipes transporting the heat to thermoelectric ...
In 1983, NASA and other US government agencies began development of a next-generation space reactor, the SP-100, contracting with General Electric and others. In 1994, the SP-100 program was cancelled, largely for political reasons, with the idea of transitioning to the Russian TOPAZ-II reactor system. Although some TOPAZ-II prototypes were ...
SAFE-30 small experimental reactor. Safe affordable fission engine (SAFE) were NASA's small experimental nuclear fission reactors for electricity production in space. [1] Most known was the SAFE-400 reactor concept intended to produce 400 kW thermal and 100 kW electrical using a Brayton cycle closed-cycle gas turbine. [2]
In the 1992-93 time period, this work was stopped due to the termination of the related SP-100 nuclear power system work and NASA's new emphasis on "better, faster, cheaper" systems and missions. In 2020, a free-piston Stirling power converter reached 15 years of maintenance-free and degradation-free cumulative operation in the Stirling ...
