Oak Ridge National Laboratory Established in 1943 for the World War
II Manhattan Project. ORNL today pioneers the development of new
energy sources, technologies, and materials and the advancement of
knowledge in the biological, chemical, computational, engineering,
environmental, physical, and social sciences. Budget: $870 million,
80% Department of Energy, 20% work for others. 3800 employees, 1500
scientists and engineers Slide 3 3 Agent Technology Trend Face to
