Some places of the Manhattan Project still remain behind the fence. The public has limited or no access to Manhattan Project sites on secure federal Department of Energy nuclear reservations. Areas behind the fence include the plutonium-producing complexes at Hanford, the uranium enrichment facilities at Oak Ridge, and the weapons research laboratory at Los Alamos. The stories of these sites begin with the Manhattan Project but go far beyond the cutting-edge science conducted there. The stories also include the people who worked there and the challenges they faced. Follow the links below to peek behind the Manhattan Project fences.
