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.
Atomic Homefront is a 2017 documentary film about the effects of radioactive waste stored in West Lake Landfill in St. Louis County, Missouri, by Rebecca Cammisa and co-produced by James Freydberg and Larissa Bills. [1] [2] [3] [4]
Online refuelling allows a nuclear reactor to continue to generate electricity during periods of routine refuelling, and therefore improves the availability and therefore the economy of the plant. Additionally, this allows for more flexibility in reactor refuelling schedules, exchanging a small number of fuel elements at a time rather than high ...
Because this could allow for weapons grade nuclear material, nuclear reprocessing is a concern for nuclear proliferation and is thus tightly regulated. Relatively high cost is associated with spent fuel reprocessing compared to the once-through fuel cycle, but fuel use can be increased and waste volumes decreased. [ 3 ]
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 waste shipments to the Waste Isolation Pilot Plant repository near Carlsbad were suspended for about two months as workers completed numerous maintenance projects at the underground facility.
Commercial LWR spent nuclear fuel contains on average (excluding cladding) only four percent plutonium, minor actinides and fission products by weight. Despite it often containing more fissile material than natural uranium , reuse of reprocessed uranium has not been common because of low prices in the uranium market of recent decades, and ...
Graphic of a dry storage of spent nuclear fuel. Radioactive waste that remains after the decommissioning is either moved to an on-site storage facility where it still is under control of the plant owner, or moved to a dry cask storage or disposal facility at another location. [9] The problem of long-term disposal of nuclear waste is still unsolved.
