The National Museum of Nuclear Science & History is an intriguing place to learn the story of the Atomic Age, from early conception, the Manhattan Project and the Cold War, to today's peaceful uses of nuclear technology. Permanent displays and changing special exhibits highlight the past, present, and future of all that is nuclear science and history. It's a place to learn, to imagine, to think, and to draw your own conclusions. We welcome visitors of all ages and all walks of life - because the history and science of nuclear energy affects each and every one of us. It's our mission to chronicle the past, describe the present, and imagine the future applications of nuclear science - beyond weapons and energy to the cutting edge of technology and healthcare. The National Museum of Nuclear Science & History is open daily from 9 a.m. to 5 p.m. We are closed on Thanksgiving Day, Christmas Day, New Year's Day, and Easter.
