Release Data Package for Hanford Site Assessments

Contaminant Release Data Package for Residual Waste in Single-Shell Hanford Tanks

“…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.…”

“…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. The release model for residual tank waste in the latest data compilation (Riley et al 2006) was recommended to be the cement model in which release is controlled by diffusion of contaminants out of the cement matrix. The cement model was chosen by Riley et al (2006) as a best option pending the development of new models based on the work described in this data package and associated contaminant release model and supporting data reports by Deutsch and coworkers at PNNL.…”

The following PNNL reports on contaminant release from waste in the SSTs have been published or are in preparation:…”
