Development work at the Idaho National Engineering and Environmental Laboratory (INEEL) has built on the FUETAP experience in the study of cementitious waste forms for the immobilization of NEEL HEW (Russell et al., 1998; Dafoe and Losinski, 1998; Lee and Taylor, 1998~.

This cement/waste mixture would be extruded into stainless steel canisters where a curing process would produce a structurally sound and geologically stable hydroceramic waste product. The canisters used would be the same as those used at the Defense Waste Processing Facility at the Savannah River Site (Defoe and Losinski, 1998~.

As a result, costs should be low relative to those processes requiring calcine redissolution and various separations. This option does depend on the existing or similar calciner being usable soon and probably entails the lowest risk and lowest development effort of any of the various cementitious processes.

This option requires significant dissolution and separations steps that have not been demonstrated in pilot-plant level operations. A regulatory reclassification ruling would be required, as above, to approve of a TRU waste stream derived from a HLW input.

It is clear from the literature on cement that a wide variety of phases may form depending on initial compositions and processing parameters. Despite the considerable literature on cementitious waste forms and the fact that cementation is a candidate technology for INEEL waste, it does not appear that much recent work has been focused on the development and characterization of the cementitious waste form.

From page 60... ...
A principal advantage is that the SEW and/or the calcined waste might be directly incorporated into the cementitious waste form with minimal or no treatment. How ever, an informed decision on He use of a cementitious waste form must be based on a thor ough analysis of experimental data gathered on waste forms typical of the selected processing technology.
