  2. Nuclear reprocessing - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reprocessing

    The first large-scale nuclear reactors were built during World War II.These reactors were designed for the production of plutonium for use in nuclear weapons.The only reprocessing required, therefore, was the extraction of the plutonium (free of fission-product contamination) from the spent natural uranium fuel.

  3. Advanced reprocessing of spent nuclear fuel - Wikipedia

    en.wikipedia.org/wiki/Advanced_reprocessing_of...

    The first reprocessing approach is based on the PUREX (Plutonium Uranium Reduction EXtraction) process, which is the standard and mature technology applied worldwide to recover uranium and plutonium from spent nuclear fuel at industrial scale. Following the dissolution of the spent fuel in nitric acid and the removal of uranium and plutonium ...

  4. PUREX - Wikipedia

    en.wikipedia.org/wiki/PUREX

    Reprocessing of spent nuclear fuel by the PUREX method, first developed in the 1940s to produce plutonium for nuclear weapons, [1] was demonstrated commercially in Belgium to partially re-fuel a LWR in the 1960s. [2] This aqueous chemical process continues to be used commercially to separate reactor grade plutonium (RGPu) for reuse as MOX fuel ...

    Infrared absorption spectra of the two UF 6 isotopes at 300 and 80 K. Schematic of a stage of an isotope separation plant for uranium enrichment with laser. An infrared laser with a wavelength of approx. 16 μm radiates at a high repetition rate onto a UF6 carrier gas mixture, which flows supersonically out of a laval nozzle.

  6. High-level radioactive waste management - Wikipedia

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

    Belgian spent nuclear fuel was initially sent for reprocessing in France. In 1993, reprocessing was suspended following a resolution of the Belgian parliament; [51] spent fuel is since being stored on the sites of the nuclear power plants. The deep disposal of high-level radioactive waste (HLW) has been studied in Belgium for more than 30 years.

  7. High-level waste - Wikipedia

    en.wikipedia.org/wiki/High-level_waste

    High-level waste is the highly radioactive waste material resulting from the reprocessing of spent nuclear fuel, including liquid waste produced directly in reprocessing and any solid material derived from such liquid waste that contains fission products in sufficient concentrations; and other highly radioactive material that is determined, consistent with existing law, to require permanent ...

    SEOUL (Reuters) -North Korea has halted the nuclear reactor at its main atomic complex, probably to extract plutonium that could be used for weapons by reprocessing spent fuel rods, a South Korean ...
