Cement based nuclear waste solidification forms

Cements are major candidates for solidification of low-level, intermediate-level and defense high-level wastes for a combination of reasons including ease of processing, necessity of only low temperature for processing, inexpensive materials required, and the resulting properties of the solidified form. Modified cement processing may be considered as an option for generating waste forms permitting higher thermal loading. Previous and current work on the physical, mechanical and thermal properties; stability; and solubility of the waste forms relevant to their immobilization of RW species is discussed. Optimally processed cement-waste mixtures may constitute a durable low temperature ceramic waste form. 8 figures, 11 tables
