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
McMaster Nuclear Reactor McMaster Nuclear Reactor The McMaster Nuclear Reactor (MNR) is a 5MW pool-type reactor located on the campus of McMaster University, in Hamilton, Ontario, Canada. MNR began operating in April 1959, as the first university based research reactor in the Commonwealth of Nations, and remains the highest-flux reactor in a university environment in Canada to this day. The reactor consists of two connected pools; the core can be located and operated in either one. This allows the core to be moved away from experimental apparatus for maintenance. MNR is an example of a reactor where the core is visible while the
