Space Nuclear Power

Data on the development of nuclear power units for use in spacecraft—nuclear rocket engines and nuclear power units—are presented. Information on the creation of a reactor unit for a transport power module based on a megawatt-class nuclear power propulsion system is provided. The research results are presented, including modeling of neutron physics, heat transfer, and gas dynamics; testing of full-scale mock-ups of the main assemblies of the reactor unit; and conducting a control physical start-up.
