Partitioning-transmutation Technology: a Potential Future Nuclear Waste Management Option
نویسندگان
چکیده
Partitioning-transmutation technology (PT) will produce radioactive wastes of different physical and chemical properties and in different amounts from those generated in the current nuclear fuel cycle. To assess quantitatively the effects of PT on waste disposal, we first analyzed the amounts of the PT wastes, assumed conditioning for each type of the waste, and then made an attempt to estimate the repository area for disposal of the PT wastes. The properties of the “hot” Sr-Cs waste form are controlling factors in determining the size of the geologic repository. The disposal area could be reduced if the “Sr-Cs” fraction is disposed in a different subsurface repository or by long-term storage of the waste under institutional control. Disposal in a subsurface repository was found to comply with the Japanese law in terms of radioactivity constraint, through a performance assessment for disposal of the “Sr-Cs” fraction.

At the Ignalina nuclear power plant (NPP), app. 22 thousands of spent nuclear fuel (SNF) assemblies from the RBMK-1500 type reactor have been accumulated [15]. During the operation of Ignalina NPP, the assemblies of SNF were stored in water pools and in storage containers, located in the interim storage facilities. According to revised Lithuanian Strategy for Management of Radioactive Waste [20...

متن کاملNuclear Development ACTINIDE AND FISSION PRODUCT PARTITIONING AND TRANSMUTATION
Partitioning and transmutation (P&T) aims at making nuclear energy more sustainable from the viewpoint of the back-end of the fuel cycle by minimising the high-level waste with respect to its mass, radiotoxicity and (possibly) repository risk. P&T mainly deals with the management – i.e. transmutation and/or special conditioning and confinement – of minor actinides and fission products, but invo...
متن کاملTransmutation of All German Transuranium under Nuclear Phase Out Conditions - Is This Feasible from Neutronic Point of View?
The German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P&T) could be considered as a technological option for the management of highly radioactive waste, therefore a wide study has been conducted. In the study group objectives for P&T and the boundary conditi...
