Nuclear material that is no longer capable of sustaining the fission process.
Fuel that has been used in a nuclear reactor and then withdrawn. Spent fuel is thermally hot and highly radioactive.
Nuclear fuel which has become deficient in fissionable material after being used in a power reactor.
nuclear reactor fuel once it has been exposed to a nuclear reaction; also called irradiated fuel.
Fuel elements that have been used in the nuclear fuel cycle and removed from the reactor because they contain too little fissile material and too high a concentration of radioactive fission products. They are highly radioactive.
A synonym for spent nuclear fuel. Acronym: SF.
fuel rods that have been used in nuclear power plants, usually from one to two years. They are highly radioactive and must be heavily shielded to contain the radioactivity.
Fuel assemblies removed from a reactor after use. Spent fuel contains a number of highly radioactive nuclides.
Fuel that has been withdrawn from a nuclear reactor following irradiation, the constituent elements of which have not been separated by reprocessing.
Nuclear fuel elements that are discharged from a nuclear reactor after they have been used to produce power.
Fuel elements that have been removed from a reactor after use because they contain too little fissile and fertile material and too high a concentration of unwanted radioactive by-products to sustain reactor operation. Spent fuel is both thermally and radioactively hot.
Spent fuel is irradiated fuel which is removed from a nuclear reactor after final use.
is used nuclear fuel awaiting disposal.
Irradiated fuel that is permanently discharged from a nuclear reactor. Except for possible reprocessing, this fuel must eventually be removed from its temporary storage location at the reactor site and placed in a permanent repository.
Fuel rods which no longer have enough fissionable uranium in them to be efficiently used to produce power.
Used fuel assemblies removed from a reactor after several years use and treated as waste.
