At the Japan Atomic Energy Research Institute (JAERI), active and comprehensive studies on partitioning and transmutation (P&T) of long-lived nuclear waste from the reprocessing processes of spent fuel has been carried out under the OMEGA program.
It is also called 'materials recycling', which includes sorting and separation of waste, washing for removal of dirt and contaminants, grinding and crushing, and reprocessing process (Aguada and Serrano 1999).
Prior to the molecular design of N-substituted 2-pyrrolidone precipitants (NRPs), differences in the conditions of these spent fuel reprocessing processes especially for the concentrations of U VI) and other relevant species were indicated.
These distinctive characteristics eliminate the necessity of both enrichment and reprocessing processes that are recognized as essentially inevitable parts in the conventional nuclear energy concept.
The North Korean diplomats read a statement from Pyongyang declaring that the reprocessing of the rods, a chemical process that the North perfected in the late 1980's after receiving considerable foreign help, had been completed on June 30.
During last decade a huge interest has been grown in the development of nearly perfect absorber materials for applications as solar energy collectors, and, more in general, for all the thermophotovoltaic applications (TPV), so to increase the absorbed power for energy harvesting, storage and conversion as well as for the reprocessing of wasted heat in industrial processes [1, 2].
Plastic, my nemesis, is especially problematic in that it can rarely be used for primary reprocessing – the process of breaking down a product and manufacturing it back into that same product.
The target waste considered was the acidic raffinate (HAR) issuing the reprocessing of the used nuclear fuels by the PUREX process.
The reprocessing of spent nuclear fuels is one of the key processes in the nuclear fuel cycle.
