| ydinpolttoaine | nuclear fuel (Nuclear fuels are obtained from inorganic minerals extracted by mining. Although they are at least partially consumed when used in nuclear reactors for the production of heat, they differ from fossil fuels in the way they release energy. Burning of fossil fuels, such as coal, oil and gas, is a chemical reaction. Nuclear fuels, such as uranium, are destroyed by a process of spontaneous disintegration, called fission, and prompted by natural radioactivity. If the process is left to occur naturally in uranium-bearing rock, the rate of change is imperceptibly small. 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) | |
| ydinpolttoaine-elementti | nuclear fuel element | |
| ydinpolttoaine-elementti | nuclear fuel element (A piece of nuclear fuel which has been formed and coated, and is ready to be placed in a reactor fuel assembly) | |
| ydinreaktio | nuclear reaction (A reaction involving a change in an atomic nucleus, such as fission, fusion, neutron capture, or radioactive decay, as distinct from a chemical reaction, which is limited to changes in the electron structure surrounding the nucleus) | |
| ydinreaktori | nuclear reactor (Device which creates heat and energy by starting and controlling atomic fission) | |
| ydinsulautuma | nuclear fusion (Combination of two light nuclei to form a heavier nucleus with release of some binding energy) | |
| ydintekninen turvallisuus | nuclear safety (Measures and techniques implemented to reduce the possibility of incidence and the potential harm posed by radioactive substances used as an energy source, a test material or in weaponry) | |

| ydinvahingon vaara | nuclear risk | |
| ydinvahingon vaara | nuclear risk (A risk connected to the functioning of nuclear power plants, by the storage or transportation of radioactive materials and involving the release of potentially dangerous levels of radioactive materials into the environment) | |
| ydinvoimala | nuclear power plant (A power plant in which nuclear energy is converted into heat for use in producing steam for turbines, which in turn drive generators that produce electric power) | |
