Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. As a nuclear technology, nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators. Generating electricity from fusion power remains at the focus of international research. This article mostly deals with nuclear fission power for electricity generation. Civilian nuclear power supplied 2,488 terawatt hours (TWh) of electricity in 2017, equivalent to about 10% of global electricity generation. As of April 2018, there are 449 civilian fission reactors in the world, with a combined electrical capacity of 394 gigawatt (GW). As of 2018, there are 58 power reactors under construction and 154 reactors planned, with a combined capacity of 63 GW and 157 GW, respectively. As of January 2019, 337 more reactors were proposed. Most reactors under construction are generation III reactors in Asia. |

Selected biography
| Priscilla Duffield (April 8, 1918 – July 21, 2009) worked on the Manhattan Project during World War II. She was secretary to Ernest O. Lawrence at the Radiation Laboratory, and to J. Robert Oppenheimer at the Los Alamos Laboratory. After the war she was executive assistant to directors of Scripps Institute of Oceanography and the National Accelerator Laboratory.
A graduate of the University of California, from which she obtained a degree in political science, Priscilla Greene started working for Lawrence in February 1942, and then for Oppenheimer later that year. She arrived in Santa Fe, New Mexico, on March 1943, and established the Los Alamos Laboratory's office. She became the office manager at Los Alamos, greeting visitors, answering the telephone, making travel arrangements, arranging security passes and accommodation, and taking notes of telephone calls. In September 1943, she married Robert Duffield, a chemist working at the Los Alamos laboratory, and changed her surname from Greene to Duffield. In the post-war years, Duffield was secretary and executive assistant to Roger Revelle, the director of the Scripps Institution of Oceanography. In November 1967, she became secretary and executive assistant to Robert R. Wilson, the founding director of the National Accelerator Laboratory, and once again she helped establish a new scientific laboratory on a new site. In later life she moved to Colorado, where she served on the board of the Uncompahgre Medical Clinic. |
