INL’s expansive desert operations site has long served as a National Environmental Research Park

Idaho National Laboratory, one of the U.S. Department of Energy’s federally funded research and development centers, is the place where generations of the nation’s best and brightest scientists and engineers have devoted their careers to advancing the state of the art in the areas of nuclear science and engineering, national and homeland security, and energy and environmental sustainability. Yet, many on the outside know little about what goes on inside INL. To help fill in some blanks about the laboratory and its host state, the following “by the numbers” listing is offered.
