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
Enrico Fermi Nuclear Generating Station "We Almost Lost Detroit", was written by local Detroit newsman John Grant Fuller (subtitled "This Is Not A Novel" to point out that it was not a work of fiction). The song "We Almost Lost Detroit", by Gil Scott-Heron is also about the Fermi 1 meltdown. Fermi 2 is a 1,198 MWe General Electric boiling water reactor owned and operated by DTE Energy. Plans to build were announced in July 1968. Initial criticality was achieved in July 1985, and full commercial operation commenced on January 23, 1988. The reactor vessel holds 764 fuel assemblies and 185 control rods which modulate
