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.

DOE report: Cost to finish cleaning up Hanford site could exceed $589 billion
The cost to complete the cleanup of the Department of Energy’s Hanford Site in Washington state could cost as much as $589.4 billion, according to the 2025 Hanford Lifecycle Scope, Schedule, and Cost Report, which was released by the DOE on April 15. While that estimate is $44.2 billion lower than the DOE’s 2022 estimate of $640.6 billion, a separate, low-end estimate has since grown by more than 21 percent, to $364 billion.
The life cycle report, which the DOE is legally required to issue every three years under agreement with the U.S. Environmental Protection Agency and Washington State Department of Ecology (Ecology), summarizes the remaining work scope, schedule, and cost estimates for the nuclear site. For more than 40 years, Hanford’s reactors produced plutonium for America’s defense program.
