Context_1 : A reactor operator (or nuclear reactor operator) is an individual at a nuclear power plant who is responsible for directly controlling a nuclear reactor from a control panel and is the only individual at a nuclear power plant who can directly alter significant amounts of reactor reactivity. The reactor operator occupies a position of great responsibility that may require him or her to start up a nuclear reactor, shut down a critical nuclear reactor, monitor reactor parameters, or respond to a casualty of the nuclear reactor. Context_2 : 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. Context_3 : The boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure water system, which turns to steam and drives the turbine. The BWR was developed by the Idaho National Laboratory and General Electric (GE) in the mid-1950s. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor. Context_4 : A gas nuclear reactor (or "gas fueled reactor") is a proposed kind of nuclear reactor in which the nuclear fuel would be in a gaseous state rather than liquid or solid. In this type of reactor, the only temperature-limiting materials would be the reactor walls. Conventional reactors have stricter limitations because the core would melt if the fuel temperature were to rise too high. It may also be possible to confine gaseous fission fuel magnetically, electrostatically or electrodynamically so that it would not touch (and melt) the reactor walls. A potential benefit of the gaseous reactor core concept is that instead of relying on the traditional Rankine or Brayton conversion cycles, it may be possible to extract electricity magnetohydrodynamically, or with simple direct electrostatic conversion of the charged particles. Context_5 : The Sodium Reactor Experiment was a pioneering nuclear power plant built by Atomics International at the Santa Susana Field Laboratory near Simi Valley, California. The reactor operated from 1957 to 1964. On July 12, 1957 the Sodium Reactor Experiment became the first nuclear reactor in the United States to produce electrical power for a commercial power grid by powering the nearby city of Moorpark. In July 1959, the reactor experienced a partial meltdown where thirteen of the reactor's forty-three fuel elements partially melted and a controlled release of radioactive gas into the atmosphere occurred. The reactor was repaired and restarted in September 1960. In February 1964, the Sodium Reactor Experiment was in operation for the last time. Removal of the deactivated reactor was completed in 1981. Technical analyses of the 1959 incident have produced contrasting conclusions regarding the types and quantities of radioactive materials released. Members of the neighboring communities have expressed concerns about the possible impacts on their health and environment from the incident. In August 2009, 50 years after the occurrence, the Department of Energy hosted a community workshop to discuss the 1959 incident. Context_6 : Atomics International was a division of the North American Aviation company (later acquired by the Rockwell International company) which engaged principally in the early development of nuclear technology and nuclear reactors for both commercial and government applications. Atomics International was responsible for a number of accomplishments relating to nuclear energy: design, construction and operation of the first nuclear reactor in California (1952), the first nuclear reactor to produce power for a commercial power grid in the United States (1957) and the first nuclear reactor launched into outer space by the United States (1965). Context_7 : In mathematics, the Thomas–Fermi equation is a second order non-linear ordinary differential equation, named after Llewellyn Thomas and Enrico Fermi, which describes the semi-classical description of charge density of a high atomic number atom under the Thomas–Fermi model. The equation reads Context_8 : The Jordan Research and Training Reactor (JRTR) is a 5MW multipurpose research reactor located on the campus of Jordan University of Science and Technology in Ar Ramtha city in northern Jordan. The reactor was inaugurated under the patronage of King Abdullah II on 7 December 2016. The reactor is the first nuclear facility that was exported by South Korea, and is Jordan's first nuclear reactor. Context_9 : Enrico Fermi ( ; ] ; 29 September 1901 – 28 November 1954) was an Italian physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of the very few physicists in history to excel both theoretically and experimentally. Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements. He made significant contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. Context_10 : The Jinshan Nuclear Power Plant or Chin Shan Nuclear Power Plant (金山核能發電廠), First Nuclear Power Plant (第一核能發電廠 or 核一), is a nuclear power plant in Shimen, New Taipei, Taiwan. Commissioned in 1978 for its first nuclear reactor, the plant is Taiwan's first nuclear power plant as well as Taiwan's smallest nuclear power plant. fact_1 : In mathematics, the Thomas–Fermi equation is a second order non-linear ordinary differential equation, named after Llewellyn Thomas and Enrico Fermi, which describes the semi-classical description of charge density of a high atomic number atom under the Thomas–Fermi model. fact_2 : Enrico Fermi ( ; ] ; 29 September 1901 – 28 November 1954) was an Italian physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. Answer: Chicago Pile-1
Output: The Thomas–Fermi equation was named in part after the physicist who was the creator of which first nuclear reactor?
