Extract

One of the major reservations regarding the use of glass as a primary nuclear waste form is its ability to retain hazardous radioactive nuclei when exposed to ground water at tenmeratures above about 75C. It is now generally accepted that the removal of radioactive nuclei from glass in an aqueous environment proceeds via two main mechanisms, i.e., either by a diffusion process (which may be driven or undriven) or by direct matrix dissolution - which, in its initial phase, also results from a diffusion related process [1]. The term "leaching" is generally employed in describing the overall process resulting in the removal of nuclei (whether they are radioactive or not) from glass that is exposed to an aqueous environment.
