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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

An overview is presented of the current activities within the international consortium participating in the Three Mile Island Unit 2 (TMI-2) Analysis Exercise, which is part of the Organization for Economic Cooperation and Development Nuclear Energy Agency/U.S. Department of Energy Joint Task Group program on TMI-2, formed to utilize the TMI-2 accident as a benchmark for severe accident computer codes. The participants have utilized various state-of-the-art severe core damage analysis computer codes to simulate the TMI-2 accident. The results of the analyses, although qualitatively similar, are quantitatively quite different. This indicates that continued development of these codes is desirable.
