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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.
Meeting Spotlight
International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2025)
April 27–30, 2025
Denver, CO|The Westin Denver Downtown
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

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.
Supplier Showcase
November 13, 2024|1:00–2:00PM (2:00–3:00PM EST)
Available to All Users
Join us for an ANS Supplier Showcase webinar and learn about the capabilities of Radiation Visualization with RadVision3D.
Christian Zircher, lead nuclear engineer, Transco Products Inc., will briefly explain the process and hardware used for capturing geospatial data along with radiological data, how that data is used to create a 3D model, and how that model can be used to perform integral RP tasks with little or no exposure to dose.
About the Presenter
Christian Zircher is the Lead Nuclear Engineer at Transco where he develops technology for radiation detection and visualization as well as manages the RadVision3D®division of the company. After completing both his Bachelor’s and Masters of Science in Nuclear, Plasma, and Radiological Engineering at the University of Illinois at Urbana-Champaign, he joined at Transco Products Inc. During his time in this position, he developed ARGOS (Augmented Reality Gamma Observation System) which outputs N-Visage and RadVision3D® data into virtual environments. He has also developed a number of other radiation visualization and radiation detector simulation systems. Outside of his product development role, he utilized the RadVision3D® system to map and identify radiation sources as well as simulate mitigation strategies for various commercial nuclear power plants and national research laboratories.
