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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

NEA panel on AI hosted at World Governments Summit
A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.

The catalyzed exchange reaction between liquid water and hydrogen gas has been studied using a hydrophobic catalyst of platinum deposited on a porous Teflon support. The reaction was studied with a new method in which a mixture of water mists and hydrogen gas moves downward through the catalyst bed co-currently. This new method was employed to improve the poor contact efficiency between liquid water and hydrogen gas in the hydrophobic catalyst bed. It was found that the reaction rate increased an order of magnitude over the conventional method in which liquid water and hydrogen gas react countercurrently. These experimental results have been analyzed in terms of a rate determining step and compared with previous ones.
