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.
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Notes on fusion
The ST25-HTS tokamak.
Governments around the world have been interested in fusion for more than 70 years. Fusion research was largely secret until 1968, when the Soviets unveiled exciting results from their tokamak (a magnetic confinement fusion device with a particular configuration that produces a toroidal plasma). The Soviets realized that tokamaks were not useful as weapons but could produce plasma in the million-degree temperature range to demonstrate Soviet scientific and technical prowess to the world.
Following this breakthrough, government laboratories around the world continued to pursue various methods of confining hot plasma to understand plasma physics under extreme conditions, getting closer and closer to the conditions necessary for fusion energy production. Tokamaks have been by far the most successful configuration. In the 1990s, the Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory produced 10 MW of fusion power using deuterium-tritium fusion. A few years later, the Joint European Torus (JET) in the United Kingdom increased that to 16 MW, getting close to breakeven using 24 MW of power to heat the plasma.

Engraved Bronze Medal
The Walter H. Zinn Medal recognizes an individual for outstanding contributions to the advancement or implementation of nuclear technology. This award is to recognize notable and sustained technical contribution, leadership, or other service that has not been widely recognized.
The award consists of an engraved medal. It is to be made no more frequently than once per year and is normally conferred during the ANS Annual Meeting.
Nominees may be from any nation, but they must not be deceased at the time the awardee is selected and need not be ANS members.
This award was established by the Operations & Power Division in 1976 with the inaugural award going to Walter H. Zinn, a pioneer in nuclear reactor development and the Society's first President, for his many contributions to the development of nuclear power. Subsequent recipients have been selected by the Operations & Power Division Honors and Awards Committee to recognize individuals who have made outstanding contributions to nuclear power. In August 2018, the OPD and ANS H&A Committee elevated this award to a national Top Tier ANS award, and it was renamed the Walter H. Zinn Medal.
Nominations must include the completed nomination form accompanied by the following supporting documents:
