Fast reactors utilization for long-lived nuclear wastes transmutation - 247

The possibility calculation studies have been carried out for transmutation long-lived wastes of the nuclear power (minor actinides and fission products) in a fast reactor with the use of special devices, containing a large amount of moderator. Such devices can replace both radial blanket sub-assemblies and axial blanket. It has been shown that the implementation of these devices will allow the achievement long-lived waste burn-up at a level of 90-95%, decreasing essentially the radiotoxicity of wastes to be buried.
