Question | Answer |
breeder reactors | A type of nuclear reactor that utilizes between 40 and 70% of its nuclear fuel and converts fertile nuclei to fissile nuclei faster than the rate of fission Thus breeder reactors actually produce nuclear fuels. |
burner reactors | A type of nuclear reactor that consumes more fissionable material than it produces. |
fission | The splitting of an atom into smaller fragments with the release of energy. |
fusion | nuclear Combining of light elements to form heavier elements with the release of energy |
high-level radioactive waste | Extremely toxic nuclear waste, such as spent fuel elements from commercial reactors. A sense of urgency surrounds determining how we may eventually dispose of this waste material. |
low-level radioactive waste | Waste materials that contain sufficiently low concentrations or quantities of radioactivity so as not to present a significant environmental hazard of properly handled |
meltdown | Refers to a nuclear accident in which the nuclear fuel forms a molten mass that breaches the containment of the reactor, contaminating the outside environment with radioactivity |
nuclear energy | The energy of the atomic nucleus that, when released, may be used to do work. Controlled nuclear fission reactions take place within commercial nuclear reactors to produce energy |
nuclear fuel cycle | Processes involved with producing nuclear power from the mining & processing of uranium to control fission reprocessing of spent nuclear fuel, decommissioning of power plants & disposal of radioactive waste. |
nuclear reactors | Devices that produce controlled nuclear fission, generally for the production of electric energy. |
radioactive decay | A process of decay of radioisotopes that change from one isotope to another and emit one or more forms of radiation. |
radioisotope | A form of a chemical element that spontaneously undergoes radioactive decay |
transuranic waste | Radioactive waste consisting of human-made radioactive elements heavier than uranium. Includes clothing, rags, tools, and equipment that has been contaminated. |
