ABSTRACT

Modeling to understand the fate and transport of contaminants in the environment is an important aspect of decommissioning. Much progress has been made over the past decade in developing computational tools to model contaminant transport through environmental media such as subsurface soil and groundwater. Certainly, advances in geochemistry and hydrology have led to a better understanding of the physical environment. Consider the Advanced Simulation Capability for Environmental Management (ASCEM) project established by the DOE’s EM program. ASCEM provides predictive capabilities for the fate and transport of contaminants using an integrated set of tools for advanced visualization, data manipulation, and uncertainty quantication for decision making. Advanced modeling of proposed cleanup activities, such as the Hanford tank farms, will enable performance and risk assessments for cleanup and closure activities across the DOE complex-modeling innovations that result in better cleanup decisions being made by regulators and various D&D stakeholders.
