Nuclear propulsion includes a wide variety of propulsion methods that use some form of nuclear reaction as their primary power source. The idea of using...

Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for...

banned nuclear explosions in space, amid concerns over nuclear fallout. Physicist Stanislaw Ulam proposed the general idea of nuclear pulse propulsion in...

Nuclear pulse propulsion or external pulsed plasma propulsion is a hypothetical method of spacecraft propulsion that uses nuclear explosions for thrust...

Aircraft Nuclear Propulsion (ANP) program and the preceding Nuclear Energy for the Propulsion of Aircraft (NEPA) project worked to develop a nuclear propulsion...

as of 2024[update], no nuclear thermal rocket has flown. Whereas all early applications for nuclear thermal rocket propulsion used fission processes,...
