Influence of Leach Rate and Other Parameters on Groundwater Migration.

摘要

A sensitivity analysis is performed in which the leaching characteristics of selected low-level radioactive waste streams are varied, and the resulting potential groundwater impacts calculated, as a function of alternative disposal site environments and alternative facility designs and operating practices. The analysis also assesses whether a leaching standard for solidified waste streams is needed to ensure safe low-level waste disposal. In the analysis, the leach rate of particular waste streams suitable for solidification (LWR concentrated liquids, Class B and C LWR ion-exchange resins and filter sludge) is varied, while the leach rate of other waste streams unsuitable for solidification is held constant.
