List of nuclear power systems in space

Add article description

This list of nuclear power systems in space includes 81 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
)
radioisotope thermoelectric generators (RTG) (usually produce heat by spontaneous decay of ²³⁸
Pu
and convert it to electricity using a thermoelectric generator)
miniaturized fission reactors (usually produce heat by controlled fission of highly enriched ²³⁵
U
and convert it to electricity using a thermionic converter)

Systems never launched are not included here, see Nuclear power in space.

Initial total power is provided as either electrical power (We) or thermal power (Wt), depending on the intended application.
