  2. Spent nuclear fuel - Wikipedia

    en.wikipedia.org/wiki/Spent_nuclear_fuel

    Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and, depending on its point along the nuclear fuel cycle , it will have different isotopic ...

  3. Nuclear fuel - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fuel

    The radiation hazard from spent nuclear fuel declines as its radioactive components decay, but remains high for many years. For example 10 years after removal from a reactor, the surface dose rate for a typical spent fuel assembly still exceeds 10,000 rem/hour, resulting in a fatal dose in just minutes. [20]

  4. Nuclear fuel cycle - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fuel_cycle

    The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end , which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end , which are necessary to safely ...

    EIA notes that the U.S. has nuclear fuel production capacity insufficient for domestic needs, with domestic mining now accounting for about 5% of the fuel used in U.S. reactors.

  6. High-level radioactive waste management - Wikipedia

    en.wikipedia.org/wiki/High-level_radioactive...

    The Nuclear Waste Policy Act of 1982 established a timetable and procedure for constructing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary storage of waste, including spent fuel from 104 civilian nuclear reactors that produce about 19.4% of electricity there. [39]

  7. Radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Radioactive_waste

    A 1000-megawatt nuclear power plant produces about 27 tonnes of spent nuclear fuel (unreprocessed) every year. [44] For comparison, the amount of ash produced by coal power plants in the United States is estimated at 130,000,000 t per year [ 45 ] and fly ash is estimated to release 100 times more radiation than an equivalent nuclear power plant.

  8. Environmental radioactivity - Wikipedia

    en.wikipedia.org/wiki/Environmental_radioactivity

    This radioisotope can be released from the nuclear fuel cycle; this is the radioisotope responsible for the majority of the dose experienced by the population as a result of the activities of the nuclear power industry. [citation needed] Nuclear bomb tests have increased the specific activity of carbon, whereas the use of fossil fuels has ...

    In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide MOX fuels. One of the main method for the separation of spent fuel is the PUREX process, which separates the plutonium and other transuranics from the remainder of the spent fuel. The uranium and plutonium are separated in turn in ...
