Translation of "nuclear fuel" into Japanese

Nuclear fuels are obtained from inorganic minerals extracted by mining. Nuclear fuels, such as uranium, are destroyed by a process of spontaneous disintegration, called fission, and prompted by natural radioactivity. In a man-made nuclear reactor the energy-releasing processes of disintegration, which in the natural state happen slowly over thousands of millions of years, are compressed into minutes. The release of energy is harnessed to generate steam which drives electricity generators. (Source: WRIGHT) [..]
