The Department of Energy has about 7,000 surplus buildings that will eventually require deactivation and decommissioning (D&D). The estimated cost of D&D for the Department's surplus facilities is over $11 billion with an additional $20 billion to stabilize, deactivate and decommission facilities which are currently active. The Office of Environmental Management is responsible for assuring that adequate technologies are available to address these D&D needs. Through the development and widespread deployment of new technologies, the Department has established a goal of reducing D&D costs by approximately $1 billion by 2006. Environmental Management uses Large-Scale Demonstration and Deployment Projects to identify and promote deployment of improved technologies throughout the Department.
