The solidification of spent ion exchange resins in a grout matrix as a means of disposing of spent organic resins produced in the nuclear fuel cycle has many advantages in terms of process simplicity and economy, but associated with the process is the potential for water/cement/resins to interact and degrade the integrity of the waste form solidified. Summarized in this document are the results of our previous investigation{sup 1} along with new results on the encapsulation of beaded anion-exchange resins in grout formulations containing ground, granulated blast furnace slag; Type 1-2 (mixed) portland cement; and additives (clays, amorphous silica, silica fume, and fly ash). The results of the studies show that the cured waste forms tested have a low leach rate for nitrate ions from the resin, a very low leach rate for {sup 99}{Tc}, and acceptable durability. The results also suggest that a surrogate waste form prepared in vinyl ester styrene binder performs satisfactorily against the wetting/drying criterion, and it should offer additional insight into future work on the solidification of spent organic resins.
