B Reactor can take a tour of the reactor by advance reservation. The reactor was designed and built by E. I. du Pont de Nemours and Company based on experimental designs tested by Enrico Fermi at the University of Chicago, and tests from the X-10 Graphite Reactor at Oak Ridge National Laboratory. It was designed to operate at 250 megawatts (thermal). The reactor occupies a footprint of (about and is tall, occupying a volume of . The reactor core itself consisted of a graphite box measuring occupying a volume of and weighing . It was penetrated horizontally through its entire length by
Nuclear power in the United States Low-Power Reactor Number One in Idaho Falls in January 1961 and a partial meltdown at the Enrico Fermi Nuclear Generating Station in Michigan in 1966. In his 1963 book "Change, Hope and the Bomb", David Lilienthal criticized nuclear developments, particularly the nuclear industry's failure to address the nuclear waste question. J. Samuel Walker, in his book "", explains that the growth of the nuclear industry in the U.S. occurred in the 1970s as the environmental movement was being formed. Environmentalists saw the advantages of nuclear power in reducing air pollution, but were critical of nuclear technology on other grounds. They
