RADIOTOXICITY AND RESIDUAL ENERGY RELEASE OF ACTINIDES AND FISSION PRODUCTS OF SPENT VVER FUEL IN LONG-TERM STORAGE

摘要

The time dependence of the residue energy release and radiotoxicity of spent VVER-1000 nuclear fuel with long-term storage or uniform accumulation in long-term storage is investigated. The calculations of the energy release take account of the contribution of α,β, and γ radiation, and the calculations of the radiotoxicity take account of the maximum admissable activity of nuclides in water and air. The data presented can be used for developing a strategy for long-term storage of spent nuclear fuel from power reactors. 4 figures, 4 tables, 4 references.
