Although the work on TPD is relatively recent, there is already a substantial amount of data on its chemical durability, and leach rates are comparable to those of other phosphate waste forms. One can anticipate important advances in the use of TPD or mixed phase assemblages of TPD-monazite (Clavier et al., in press) in reprocessing spent nuclear fuel, processing HEW, and developing new nuclear waste forms for special applications.

Release rate data from actual radioactive waste forms is needed to evaluate the safety of emplacing nuclear wastes in geologic media. However, in addition to waste form development studies, such as the leach test just described, a comprehensive program was started to obtain release data from candidate waste forms for geologic disposal.
