Abstract
Investigations of the characteristics of lead phosphate glasses pertinent to the use of these materials as a storage medium for high-level nuclear waste have been carried out. By combining lead phosphate glass with various types of simulated high-level nuclear waste, it is possible to form a highly corrosion resistant, homogeneous, easily processed glass. For corroding solutions at 90° C, with solution pH values in the range between 5 and 9, the corrosion rate of the lead phosphate nuclear waste glass is at least 10 2 to 10 3 times lower than the corrosion rate of a comparable borosilicate nuclear waste glass. Lead phosphate nuclear waste glasses can be prepared at temperatures as low as 800°C, since they exhibit very low melt viscosities in the 800–1050°C temperature range. These waste-loaded glasses do not readily devitrify at temperatures as high as 550°C and are not adversely affected by large doses of gamma radiation in H 2O at 135°C. It appears that lead phosphate waste glasses can be prepared with minimal modification of the technology developed for processing borosilicate glass nuclear waste forms.
