Design Data
Evaporator bottoms;
Filter sludges / slurries;
Spent resin;
Decontamination solutions;
Solid radwaste (for example, spent filter elements, super compacted waste etc.).
· System throughput: 3 drums/hour.
Advantages
· Proven system design;
· Customised application;
· The final properties of grout prepared with clean water can be tuned to the
characteristics needed e.g. leachability, compressive strength and water resistance;
· Macroencapsulated waste forms do not affect chemistry or the aging characteristics of
the cement.

7.4.3.3 Cast Iron Container
The cast iron container is a multi-purpose cask mainly used for the processing, handling and
storage of ILW. As this container provides a safe handling and storage enclosure it is suitable
for dewatered resins, evaporator concentrates and other components of higher specific
activities.
