【 摘 要 】

In support of accelerated mission goals, glass formulation efforts have been focused on melt rate, waste loading, and waste throughput for the DWPF. With respect to melt rate, the general trend to improve melt rate has been to enhance the total alkali concentration in the glass system by increasing the alkali concentration in the frit, utilizing (or targeting) a less washed sludge, or using a combination of the two. Cozzi et al. (2002) defined thirty-one glasses that intentionally challenged either the current durability model over an extremely broad compositional region or the Salkali and Al2O3 criteria proposed by Herman et al. (2002). These glasses were batched, melted, and subjected to the PCT. In this report, the results of both compositional analysis and PCT response are discussed.
