The Department of Energy is hosting a Technical Exchange at the Hanford Site on
April 13-14, 2010.

The Performance Assessment Community of Practice has been chartered to advise the Office of Environmental Management Tank Waste Corporate Board regarding performance assessments and performance assessment-like analyses, promote consistency in the preparation of performance assessments across the Department of Energy (DOE) complex, foster exchange of information among performance assessment practitioners, and develop appropriate guidance for performance assessments such that they are based on sound science and are defensible.

The purpose of this technical exchange is to provide a venue for performance assessment and risk assessment practitioners, managers and regulators, and contributors to the Cementitious Barriers Partnership and Advanced Simulation Capability for Environmental Management project to share plans and experiences and share ideas for future performance assessment and risk assessment modeling. The technical exchange will include a combination of plenary presentations and discussions with breakout sessions for specific topics. Discussions will emphasize areas for improved consistency and solicit suggestions for future developments related to modeling tools. A breakout discussion session is also planned to address: DOE Order 435.1 Update, regulatory challenges for performance and risk assessment modeling, and other topical areas. Arrangements have also been made for a GoldSim modeling roundtable at the conclusion of the workshop for participants who are interested in sharing experiences related to the use of GoldSim for their simulations.

Currently, planned topics for presentations include:

  • DOE Headquarters Environmental Management Activities
  • Nuclear Regulatory Commission perspectives on performance assessments
  • Advanced Simulation Capability for Environmental Management project
  • Cementitious Barriers Partnership
  • Examples of modeling applications from across the DOE Complex, including Tank Closure, Waste Disposal, and Area Closure projects
  • International Program activities related to modeling.
