New volume reduction systems, which treat most of nuclear power plant radioactive wastes including liquids and sludges, have been developed and they are ready for commercial use. The main feature of the system is that mixed wastes having different chemical and physical characteristics can be treated by one unit. This report describes the outline of the system, mathematical simulation models to estimate the operational characteristics of the key components, on-line computer control system using these models, and packaging technique for the long term storage of the wastes.
