What other reactor did the supervisor of construction of the reactor that went critical under the supervision of Enrico Fermi build?
Walter Zinn Walter Henry Zinn (December 10, 1906 – February 14, 2000) was a nuclear physicist who was the first director of the Argonne National Laboratory from 1946 to 1956. He worked at the Manhattan Project's Metallurgical Laboratory during World War II, and supervised the construction of Chicago Pile-1, the world’s first nuclear reactor, which went critical on December 2, 1942, at the University of Chicago. At Argonne he designed and built several new reactors, including Experimental Breeder Reactor I, the first nuclear reactor to produce electric power, which went live on December 20, 1951.
Next Generation Nuclear Plant A Next Generation Nuclear Plant (NGNP) is a generation IV very-high-temperature reactor (VHTR) that could be coupled to a neighboring hydrogen production facility. It could also produce electricity and supply process heat. Up to 30% of this heat could be used to produce hydrogen via high temperature electrolysis significantly reducing the cost of the process. The United States Department of Energy issued in 2007 a "request for expressions of interest from prospective industry teams" that want to provide design services for developing the NGNP.
