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 Power Plant (Italy) Enrico Fermi Nuclear Power Plant (Italy) Enrico Fermi Nuclear Power Plant was a nuclear power plant at Trino (often referred to as ‘Trino Vercellese’, meaning ‘Trino in the Province of Vercelli’), in north-west Italy. Consisting of one 260 megawatt pressurized water reactor (PWR) from the vendor Westinghouse Electric Corporation, it operated from 1964 until 1990. Trino was in 1964 the third ever commercially operated PWR worldwide, and it had the second highest megawatt-capacity of them. It was closed down following the Italian nuclear power referendum, 1987. The experimental enrichment plant, EUREX, near the power plant, was closed down in 1984.
