MSE's site closure support focuses on finding solutions to help the Department of Energy, other agencies, and private clients at various closure sites across the United States. Our experience includes implementing alternative technologies to enhance early site closure and/or address long-term stewardship. Currently, we are addressing specific closure needs at various Department of Energy sites including Hanford, Oak Ridge, Mound, and Fernald.
