ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Nominations open for CNTA awards
Citizens for Nuclear Technology Awareness is accepting nominations for its Fred C. Davison Distinguished Scientist Award and its Nuclear Service Award. Nominations for both awards must be submitted by August 1.
The awards will be presented this fall as part of the CNTA’s annual Edward Teller Lecture event.
John W. Simpson was elected the 19th president of the American Nuclear Society (ANS). Simpson was a charter member of the Society and elevated to Fellow of ANS in 1958.
John Simpson was born on September 25, 1914. He was top executive and engineer for the Westinghouse Electric Corporation who played a major role in developing the nation’s first commercial nuclear power plant and its first nuclear-powered submarine, the U.S.S. Nautilus.
John joined the Marines in 1933. Just as he was completing basic training, his application to attend the United States Naval Academy was accepted. He graduated from Annapolis in 1937. But in his last year at the academy, he developed near-sightedness and was denied a commission. Instead, he went to work as a junior engineer at the Westinghouse switchboard division in East Pittsburgh, Pa. There he met Rickover, the Navy’s contract officer on the switchboard project. At the same time, he pursued a master’s degree in electrical engineering at the University of Pittsburgh. He received the degree in 1941.
In 1946, he took a two-year leave of absence to work at Oak Ridge National Laboratory. There, with Rickover and a group of engineers and scientists, he helped draft plans for the first attempt at applying nuclear energy to the generation of electricity. He returned to Westinghouse in 1949 and was named assistant manager of engineering at the Bettis Atomic Power Laboratory in Pittsburgh. There, in addition to working on the Nautilus with Rickover, he helped design propulsion plants for the U.S.S. Long Beach and the U.S.S. Enterprise, the nation’s first nuclear surface ships, and for the U.S.S. George Washington, the first nuclear submarine that carried Polaris missiles.
In 1951, Westinghouse received a contract from the federal Atomic Energy Commission to build the first atomic electricity-generating plant, at Shippingport, Pa., and John became manager of the project. In the late 1950s, he organized the company’s astro-nuclear laboratory, which won the federal government’s first contract to develop a nuclear reactor for rocket propulsion. It was successfully tested, but funding was later diverted for other activities.
John was president of the Westinghouse Electric Power Systems Company from 1969 to 1977. He was awarded the Edison Medal of the Institute of Electrical and Electronics Engineers in 1971 for his contributions to electricity generation and naval and space propulsion. His citation reads: “The extent to which he influenced the transition from scientific discovery to practical application in all three areas is to a substantial degree responsible for the eminence of the United States in the atomic energy field today.”
John W. Simpson passed away on January 4, 2007.
