Abstract
Water-containing bibulous solids such as ion-exchange or filter matters from a nuclear electricity-generating power plant are introduced into a final storage container and heated therein under vacuum to dewater the solids and provide a high interstitial volume. The latter is substantially filled with radioactive salts by introducing flowable evaporator concentrate in one or more stages and for each stage heating the container under vacuum so as to drive off the concentrate water.
