【 摘 要 】

A research-scale, liquid-fed, ceramic-melter was used to conduct a flowsheet evaluation of a nonradioactive surrogate of sodium-bearing waste currently being stored in underground tanks at the Department of Energy?s Idaho National Engineering and Environmental Laboratory. During this 120-h melter test, the processing characteristics of a glass formulated to have a high sulfur capacity were evaluated with and without reductant (sucrose and glycolic acid) additives. Beyond processing rates, this integrated melter/off-gas system demonstration test evaluated the impacts of reductant type (if used) and concentration upon 1) the partitioning of volatile (sulfur, mercury, and the halogens) and nonvolatile effluents, 2) the oxidation state of the melter glass, 3) the reduction of waste constituent nitrate, 4) the composition of secondary waste streams, and 5) the durability of the melter?s glass product.
