The advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
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.
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 ...
Nuclear fuel cycle Japan Nuclear Fuel Limited is involved in the production of nuclear fuel, as well as the reprocessing, storage and disposal of nuclear waste. Kazatomprom: Kazakhstan Nuclear holding Kazatomprom is a state-owned nuclear holding company in Kazakhstan.
The first shipments of spent fuel arrived at the site in 1965, and reprocessing began the next year. In 1969, Nuclear Fuel Services was acquired by Getty Oil. [4]: 5 A 23-ton cask containing a single fuel element is lowered into the unloading pool at Nuclear Fuel Services' West Valley reprocessing plant circa 1966.
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 ...
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 ...
Nuclear fuel cycle begins when uranium is mined, enriched and manufactured to nuclear fuel (1) which is delivered to a nuclear power plant. After usage in the power plant the spent fuel is delivered to a reprocessing plant (if fuel is recycled) (2) or to a final repository (if no recycling is done) (3) for geological disposition.
