Assessments of future arisings of conditioned radioactive wastes for waste management system studies

The report describes two assessments of conditioned radioactive waste arisings. One is based on existing and committed nuclear installations and the other on an assumed nuclear power generation scenario representing a moderate growth in nuclear generation. Radioactive wastes arise from: i. Commercial Nuclear Reactors, ii. Fuel Cycle Activities, iii. Research, Industrial and Medical activities. Decommissioning wastes are also considered. The study uses the SIMULATION 3 code which models waste material flows through a system of waste treatment and packaging to disposal. With a knowledge of the accumulations and average production rates of untreated wastes and their nuclide compositions (or total activities), the rates at which conditioned wastes become available for transportation and disposal are calculated, with specific activity levels.
