United Heavy Machinery: Russia Nuclear engineering United Heavy Machinery is a provider of primary circuit equipment for nuclear power plants with pressurized water reactors. Its subsidiary Izhora Plants produces forgings for nuclear reactors. Atommash: Russia Nuclear engineering Atommash is a manufacturer of components for nuclear power plants.
A nuclear electric rocket (more properly nuclear electric propulsion) is a type of spacecraft propulsion system where thermal energy from a nuclear reactor is converted to electrical energy, which is used to drive an ion thruster or other electrical spacecraft propulsion technology.
Nuclear-powered rockets are not used to lift off the Earth. Nuclear thermal rockets can provide great performance advantages compared to chemical propulsion systems. Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples:
The first operation of a nuclear aircraft engine occurred on January 31, 1956 using a modified General Electric J47 turbojet engine. [5] The Aircraft Nuclear Propulsion program was terminated by President Kennedy after his annual budget message to Congress in 1961. [1] The Oak Ridge National Laboratory researched and developed nuclear aircraft ...
It is a world leader in the field of Hall thruster development and a leading Russian developer and manufacturer of electric propulsion systems. [5] The company's third-generation electric propulsion system SPT-100 has been certified in accordance with western standards and the company is actively marketing the system to foreign customers.

The machine will be housed 1,000 feet underground at the Nevada National Security Site, formerly known as the Nevada Test Site, and will have a 400-foot-long accelerator, made up of 102 cells ...
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
Examples of concepts that use nuclear power for space propulsion systems include the nuclear electric rocket (nuclear powered ion thruster(s)), the radioisotope rocket, and radioisotope electric propulsion (REP). [6] One of the more explored concepts is the nuclear thermal rocket, which was ground tested in the NERVA program.
