ASCEM’s new developments will allow EM researchers to address larger and more intricate problems—a necessity in dealing with the challenging waste sites in the EM complex. A key result of ASCEM’s advances will be the creation of next-generation performance assessment (PA) capabilities for EM, made possible by improvements to predictive capabilities. These enhanced capabilities will allow for more realistic modeling of key processes and uncertainty to support improved decision-making for the most difficult EM problems, while maintaining a graded modelling approach for less complex sites.
Updating DOE-EM’s simulation capability with the most advanced scientific understanding will enable predictions that support decisions on the management and disposition of challenging waste. It will provide a consistent approach for performance and risk assessment that site personnel and regulators can use to guide and assess remedial actions (including natural attenuation), site closure, and long-term waste management decisions. An anticipated outcome will be increased public confidence in the reliability of EM decision-making and reduced long-term maintenance and monitoring costs.
