摘要：

Precipitation and separation of the radioactive matter from the bulk liquid, has been developed at Kernforschungszentrum Karlsruhe (KfK) as an alternative to direct solidification of Medium Level Liquid Waste (MLLW)-concentrates by bituminization or cementation. More than 90% of the total radioactivity is removed from MLLW stream by absorbing it on surface rich precipitate, which is ultimately vitrified with HLLW. An addition of MLLW-precipitate to a matrix (glass or glass-ceramic), to which HLLW has already been incorporated, showed no significant decrease in product quality or increase in product amount.
