This list of nuclear power systems in space includes 83 nuclear power systems that were flown to space, or at least launched in an attempt to reach space. Such used nuclear power systems include: radioisotope heater units (RHU) (usually produce heat by spontaneous decay of 238. Pu.
Nuclear power in space is the use of nuclear power in outer space, typically either small fission systems or radioactive decay for electricity or heat. Another use is for scientific observation, as in a Mössbauer spectrometer. The most common type is a radioisotope thermoelectric generator, which has been used on many space probes and on ...
Kilopower is an experimental U.S. project to make new nuclear reactors for space travel. [1][2] The project started in October 2015, led by NASA and the DoE ’s National Nuclear Security Administration (NNSA). [3] As of 2017, the Kilopower reactors were intended to come in four sizes, able to produce from one to ten kilowatts of electrical ...
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] The fuel was uranium nitride in a core of 381 pins clad ...

TerraPower, LLC. TerraPower is an American nuclear reactor design and development engineering company headquartered in Bellevue, Washington. TerraPower is developing a class of nuclear fast reactors termed traveling wave reactors (TWR). [1] TWR places a small core of enriched fuel in the center of a much larger mass of non-fissile material, in ...
SNAP-11 →. SNAP-10A (Systems for Nuclear Auxiliary Power, [3] aka Snapshot for Space Nuclear Auxiliary Power Shot, also known as OPS 4682[4]) was a US experimental nuclear powered satellite launched into space in 1965 [5] as part of the SNAPSHOT program. [6][4] The test marked both the world's first operation of a nuclear reactor in orbit, [7 ...
A fusion rocket is a theoretical design for a rocket driven by fusion propulsion that could provide efficient and sustained acceleration in space without the need to carry a large fuel supply. The design requires fusion power technology beyond current capabilities, and much larger and more complex rockets. Fusion nuclear pulse propulsion is one ...
