The chief rival to the light water reactor (LWR) in the design of nuclear power plants in the post-World War II era was the gas-cooled reactor. While the gas-cooled, graphite-moderated reactor is similar to the pressured-water reactor in that both use a fluid to transport heat to the steam generator, these reactors are inherently larger and have a higher operating temperature than water-cooled reactors. They also were more expensive to build and maintain than light water reactors. The technology for gas-cooled reactors was developed most fully by British and French scientists after World War II. The gas-cooled design became the chief competition to the American LWR monopoly in the 1950s and 1960s. This battle pitted American technology against British-French technology with the Americans winning. By 1970, the gas-cooled reactor was no longer a serious contender in this competition.
Geiger, Hans Wilhelm
Hans Geiger (1882-1945) was a German physicist who is most famous for his research on alpha particle scattering and the Geiger counter. He was born on September 30, 1882, at Neustadt, Germany. His education was at the University of Munich and the University of Erlangen. He received his doctorate in physics from the University of Erlangen in 1906. Geiger was studying at the University of Manchester in 1907 under Arthur Schuster when Ernest Rutherford arrived, and for the next five years, they worked
