spent fuel


Also found in: Acronyms.

spent fuel

[′spent ′fyül]
(nucleonics)
Nuclear reactor fuel that has been irradiated to the extent that it can no longer effectively sustain a chain reaction because its fissionable isotopes have been partially consumed and fission-product poisons have accumulated in it.

Advance Market Analytics released a comprehensive study of 200+ pages on 'Nuclear Spent Fuel' market with detailed insights on growth factors and strategies.
The IAEA has repeatedly called for newcomer countries to join and ratify the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.
The guidelines also urged the utility operators to increase their capacity to keep spent fuel in long-term storage until it's needed for reprocessing at Rokkasho.
A handheld optical instrument called an Improved Cerenkov Viewing Device (ICVD) is used to confirm the presence of spent fuel stored underwater.
The Russian law on environmental protection allows transportation of spent fuel assemblies to Russia, but does not sets forth the order for transportation of spent nuclear fuel.
Most of it remains in pools, which cool the spent fuel for several years once it comes out of the reactors.
Commenting on the objection that transport and disposal of spent fuel from nuclear power plants will be an unmanageable problem, he said "An idea of the smallness of the volume involved can be gauged from the fact that all the spent fuel discharged from both plants over their whole 60-year lifetime would not fill up a room of dimensions 15m x15m x 8m".
He said after sufficient cooling, the spent fuel can be transferred to a secure long term storage facility, adding there are tried and tested procedures for carrying out such a transfer without undue risk.
* The NRC should consider alternatives to minimize the risks of storage of spent nuclear fuel and high level waste, including placement below ground level, elimination of the current practice of high-density storage of spent fuel in pools, and more robust designs for storage casks.
and to spent fuel and radioactive waste from military or defence programmes if and when such materials are transferred permanently to
* The loss of water exposing the spent fuel would result in overheating and cause melting, igniting the fuel's zirconium metal cladding--resulting in a fire that could deposit large amounts of radioactive materials over hundreds of miles.
Five years after discharge from reactor cores, spent fuel can and should be transferred to dry storage.
