Stone, J. A.

Some of the favorable and unfavorable characteristics of concrete as a matrix for solidification of SRP waste, as found in this study, are listed. Compressive strength and leachability of waste forms containing /sup 90/Sr and alpha emitters are very good. The waste forms have reasonable long-term thermal stability up to 400/sup 0/C, although water is evolved above 100/sup 0/C. Long-term radiation stability of the solid, as measured by strength and leachability, is excellent. For the unfavorable characteristics, methods are available to overcome any problems these properties might cause. /sup 137/Cs leachability can be reduced by additives such as zeolite. Steam generation can be reduced by an initial degassing step; however, radiolytic gassing may require further study. Set times can be retarded with additives. 10 figs.
