Objetivo The objective of this proposal is the long-term disposal of radioactive wastes at minimum volume. It will be achieved by the development of efficient methods for the decontamination of aqueous nuclear waste effluents from actinide elements, fission products, activation products and heavy metals using highly selective inorganic ion exchangers designed for use in column operations. High selectivities and maximised capacity usage of the materials will minimise the volume of exchanger waste for disposal and make exhaustive decontamination of the waste stream, and thus decategorisation, a possibility. Further applications of highly selective materials for ion exchange are hindered because large amounts are unavailable in granular form for columns. The range of applications of present materials is narrow, despite applicability to radionuclide waste treatment. The materials under study give the means to design and direct their ion exchange behaviour towards the most important radionuclides. The programme will enable a better understanding of exchanger selectivity, produce well-characterised crystalline exchangers at the lab and pilot scale and evaluate their potential for the separation of the most common nuclides in simulated and then real wastes. Materials will be used in highly effective column operations for industrial applications and make use of thermodynamic and column models to assist ; application to industrial processes. The partnership has considerable experience in the whole range of nuclear waste types from Nuclear Power stations (IVOINTER) to reprocessing and decommissioning wastes (BNFL). These partners have engineering and design capabilities to allow development into operational plants and direct experience of industrial scale ion exchange plants operation. Crosfield and IVOINTER have expertise in the synthesis of industrial scale quantities of exchanger materials. Salford has experience in the laboratory synthesis, characterisation, and performance of ion exchangers. Helsinki has experience in the evaluation of exchanger materials, thermodynamic and column models to allow performance prediction.
