FORFARANDE OCH ANORDNING FOR YTBELEGGNING AV FAST MATERIAL

摘要

An inert carrier process for drying radioactive waste material and for incorporating the dry material into a binder from which the dried material will not be leached is disclosed. In this process, a hot inert liquid carrier is provided into which the solution to be dried is introduced under extremely turbulent conditions. The solvent flashes off leaving the dried particles dispersed in the inert carrier which carries these particles to a mixing station where a binder for the particles is injected under turbulent conditions. The binder preferentially wets the particles and the coated particles are carried to a separator section where the binder coated particles coalesce and separate from the carrier as a second phase. Thereafter a curing agent can be added to the binder.
