PERFORMANCE ASSESSMENT COMMUNITY OF PRACTICE TECHNICAL EXCHANGE MEETING
Modeling the Performance of Engineered Systems for Closure and Near-Surface Disposal
Objective: The purpose of this technical exchange is to understand the current state-of-practice, state of evolving science and opportunities to improve fidelity and reduce uncertainty in models used to estimate the performance of the engineered systems for environmental assessments. The engineered system is defined to include the waste form(s), engineered barriers to contaminant release such as vaults, tanks, caps, and the near field physical-chemical interactions of these systems with the immediate surroundings that impact contaminant release. For each topic, the presentations and discussions are intended to provide (i) state of practice, and (ii) state of science, with discussion focused on opportunities, near-term and longer-term directions.
Dates: July 13-14, 2009
Location: Salt Lake City Marriott University Park
Participants: DOE, NRC, EPA, State Regulators, National Laboratories, Academia, DOE Contractors, International
