The concept of a chemical-engineering complex and its operation stability is described for a radioactive-waste separation and transmutation plant. In the framework of the plant, this chemical complex runs in a closed cycle with a nuclear transmutation reactor driven by a 1 GeV–100 mA class accelerator. Heavy water provides circulation of materials to be transmuted in the reactor blanket and transports the irradiated suspension to and from the chemical-engineering complex for reprocessing and further disposal of transmutation products. Modeling and experimental tests of radiolytic decomposition and corrosion were made in order to evaluate the operation stability of the desired separation and transmutation cycle. Preliminary calculations were made for some methods to suppress gas evolution from water (deuterium) solutions with thorium and transuranium nuclides or from suspensions of their oxides at a pressure of 10 MPa, a temperature of 285°C and radiation doses up to 5×107 Gy. The results were checked experimentally. Also the change in size of the suspended particles during irradiation was measured. Additionally, corrosion rates of zirconium alloy tubes were estimated from experiments under the same conditions. |
