RITEG (RTG) is a Radioisotope Thermoelectric Generator, it's an electrical generator with nuclear fuel. It means, you are need fuel only by construction of it. It needs a lot of nuclear energy, but only once.
- Added integration with Plutonium Energy: MOX-fuel has 20 GJ energy. New tier of RITEG will more powerful, but with shorter half life period.
- Added integration with Nuclear Fuel, 10 breeder fuel cells (each 4 GJ) can be proceed to make new RITEG.
