    Reprocessing Spent Nuclear Fuel for Nuclear Power. In the closed nuclear fuel cycle, spent reactor fuel is reprocessed to recover the uranium and plutonium to fuel nuclear reactors using the PUREX process. Reprocessing also reduces the amount of radioactive waste that must be managed. Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors. The reprocessed uranium, also known as the spent fuel .

    Thus the amount of fissile material in irradiated fuel is only decreased by 30% from that in the fresh fuel. Irradiated fuel is removed from the reactor, not because there is no more energy to extract, but because too many neutron-absorbing fission products have built up. Reprocessing is a complex, chemical process that involves chopping up.

Recent Advances in Reprocessing of Irradiated Fuel. Nuclear Engineering. Part XX. Symposium : Rodger & Ferguson. The processes for non-aqueous reprocessing of spent nuclear fuel are briefly described: refining, melting, oxidation-reduction of oxide fuel, fluoride volatility method.

The advantages and disadvantages are estimated. The processes in molten salt are examined and an attempt of their classification and analysis is by:   Though a fissile isotope of uranium, U is formed by neutron irradiation of fertile thorium in reactors; the subsequent reprocessing of irradiated thorium for recovery, purification, and further handling of U product (accompanied by U) has remained a challenge because of the complex radiological problems associated with irradiated by: 1.

Nuclear fuel reprocessing is a controversial process by which spent nuclear fuel is reprocessed to extract uranium. Reprocessing of high-level waste is controversial because it produces large quantities of liquid high-level waste from the solvents used, and also because extracted plutonium or uranium is easily amenable to illicit nuclear weapons.

Reserve for reprocessing of irradiated nuclear fuel In order to provide for the costs required for reprocessing irradiated nuclear fuel (except for those without specific reprocessing plans) generated in proportion to the corresponding combustion of nuclear fuel, reserve is made at the present value (discount rate %) of such costs.

Irradiated nuclear fuel - material containing uranium, thorium and/or plutonium isotopes which has been used to maintain a self-sustaining nuclear chain reaction. Plutonium - the resultant mixture of isotopes of that material extracted from irradiated nuclear fuel from reprocessing.

Prior to being used in commercial nuclear fuel, uranium is typically enriched to 3–5% in U. If the enrichment process discards depleted uranium at percent U, it takes more than seven tonnes of uranium feed to produce one tonne of 4%-enriched uranium.

The evolution of the reprocessing of irradiated fuel and the recovery of plutonium from it is traced out, starting by following the Manhatten project up to the present time.

The results of investigations of the leading operation of a nonaqueous technology for reprocessing fuel elements from nuclear reactors — dissolution of fuel claddings in a zinc-based melt — are presented. Data obtained in experiments on simulators and samples of irradiated fuel elements in standard BOR and SM-2 packages with different burnup and holding time are presented.

In the. A process for separately recovering uranium, plutonium and neptunium substantially free of fission products from irradiated nuclear fuel is presented in which the fuel is dissolved in a strong mineral acid forming an aqueous dissolved nuclear fuel solution and treated to separate the uranium, plutonium and neptunium therefrom substantially free of said fission products by the sequential steps Cited by: Non -aqueous (molten salt) reprocessing of irradiated spent nuclear fuels is being studied between the ITU and CRIEPI.
