“…Contaminant release from Hanford waste and engineered waste forms has been estimated using mathematical models and various levels of data for many years as part of site and performance assessments. An initial data catalog of release models was prepared by Riley and Lopresti (2001) and was subsequently updated in 2003 and 2006 (Riley and Lopresti 2003;Riley et al 2006). In addition to providing descriptions of a number of mathematical models, such as a soil-debris model, solubility model, cement model, and glass model, these documents provide references to data sources for the various models.…”
