The radioisotope thermoelectric generator which is employed in deep space exploration, converts heat from the natural decay of radioisotope materials into electrical power directly. The ~(238)Pu radioisotopic fuel has potentials at decay period, specific thermal power and radiation protection, so it is widely adopted in space application. This paper outlines the production of ~(238)Pu and its separation and purification process.
