Mobile fission and activation products in nuclear waste disposal.
When disposing nuclear waste in clay formations it is expected that the most radiotoxic elements like Pu, Np or Am move only a few centimetres to meters before they decay. Only a few radionuclides are able to reach the biosphere and contribute to their long-term exposure risks, mainly anionic species like I129, Cl36, Se79 and in some cases C14 and Tc99, whatever the scenario considered. The rec...
متن کاملMolten Salt Critical Rea~ors for the Transmutation of Transuranics and Fission Products
The primary goal of this work is to study the feasibility of designing molten salt reactors to be critical when fed with, and only with the transuranium isotopes (TUS) and long lived fission products produced in LWRS. Another goal is to estimate the transmutation characteristics which might be attainable from such a Molten Sal t Transmuting Reactor (MSTR). Both moderated and unmoderated MSTR sy...
متن کاملTransmutation of Fission Products
Studies of transmutation of long-lived fission products by accelerator and by fission reactor at PNC are described. Four transmutation methods by accelerators are compared in terms of transmutation energy and transmutation rate. A super-powered electron linear accelerator which could transmute a large quantity of fission products has been studied and development of PNC test linac in this line i...
متن کاملSolid Waste Biodegradation Enhancements and the Evaluation of Analytical Methods Used to Predict Waste Stability
Conventional landfills are built to dispose of the increasing amount of municipal solid waste (MSW) generated each year. A relatively new type of landfill, called a bioreactor landfill, is designed to optimize the biodegradation of the contained waste to stabilized products. Landfills with stabilized waste pose little threat to the environment from ozone depleting gases and groundwater contamin...
متن کاملEvaluation of Fluorapatite as a Waste-Form Material
Fluorapatite, fluorinated calcium phosphate, has been identified as a potential matrix for the entombment of the zirconium fluoride fission product waste stream from the proposed FLEX process. If the efficacy of fluorapatitebased waste-storage can be demonstrated, then new and potentially more-efficient options for handling and separating high-level wastes, based on fluoride-salt extraction, wi...
