Nuclear propulsion includes a wide variety of propulsion methods that use some form of nuclear reaction as their primary power source.[1] The idea of using nuclear material for propulsion dates back to the beginning of the 20th century. In 1903 it was hypothesized that radioactive material, radium, might be a suitable fuel for engines to propel cars, planes, and boats.[2] H. G. Wells picked up this idea in his 1914 fiction work The World Set Free.[3] Many aircraft carriers and submarines currently use uranium fueled nuclear reactors that can provide propulsion for long periods without refueling. There are also applications in the space sector with nuclear thermal and nuclear electric engines which could be more efficient than conventional rocket engines.
