Fission thermal rocket
A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction, often nuclear fission, replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor and then … See more Nuclear-powered thermal rockets are more effective than chemical thermal rockets, primarily because they can use low-molecular-mass propellants such as hydrogen. As thermal rockets, … See more A nuclear thermal rocket can be categorized by the type of reactor, ranging from a relatively simple solid reactor up to the much more … See more An atmospheric or orbital rocket failure could result in the dispersal of radioactive material into the environment.
