| liability for nuclear damages Subjection to a legal obligation, such as financial recompense or ecological reparations, for any harm or damage inflicted on persons, property or the environment during the production, use or transport of radioactive materials used as an energy source or in weaponry | dliteanas as damáiste núicléach |
| nuclear accident An event occurring in a nuclear power plant or anywhere that radioactive materials are used, stored, or transported and involving the release of potentially dangerous levels of radioactive materials into the environment | tionóisc núicléach |
| nuclear debate The ongoing, public discussion and dispute over the uses of energy | díospóireacht núicléach |
| nuclear energy Energy released by nuclear fission or nuclear fusion | fuinneamh núicléach |
| nuclear energy legislation | reachtaíocht ar fhuinneamh núicléach |
| nuclear energy use Nuclear energy is employed in the industrial sector, in the production of other energy types, in the medical and scientific research field, in transportation, in the production of nuclear weapons, etc. | fuinneamh núicléach a úsáid |
| nuclear explosion accident, An unintentional release of energy from a rapid reaction of atomic nuclei yielding high temperatures and radiation potentially harmful to human health and the environment | pléascadh núicléach (tionóisc) |
| nuclear facility A place, including buildings, where all the activities relating to nuclear research are performed | áis núicléach |
| nuclear fission The division of an atomic nucleus into parts of comparable mass; usually restricted to heavier nuclei such as isotopes of uranium, plutonium, and thorium | scoilteadh núicléach |
| 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 | breosla núicléach |
| 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 | gné de bhreosla núicléach |
| nuclear fusion | comhleá núicléach |
| nuclear fusion Combination of two light nuclei to form a heavier nucleus with release of some binding energy | comhleá núicléach |
| nuclear hazard Risk or danger to human health or the environment posed by radiation emanating from the atomic nuclei of a given substance, or the possibility of an uncontrolled explosion originating from a fusion or fission reaction of atomic nuclei | guais núicléach |
| nuclear physics The study of the characteristics, behaviour and internal structures of the atomic nucleus | fisic núicléach |
| 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 | stáisiún núicléach |
| nuclear power plant disposal | diúscairt ar stáisiún núicléach |
| 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 | imoibriú núicléach |
| nuclear reactor Device which creates heat and energy by starting and controlling atomic fission | imoibreoir núicléach |
| nuclear research centre A facility in which scientists and other researchers study the behavior and characteristics of atomic nuclei through testing and other forms of experimentation, often to invent new technology with scientific, medical and industrial purposes | ionad taighde núicléach |
| 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 | baol núicléach |

| nuclear test Test performed to evaluate nuclear weapons | tástáil núicléach |
| nuclear weapon Any bomb, warhead, or projectile using active nuclear material to cause a chain reaction upon detonation | arm núicléach |
