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
Mathematics & Computation
Division members promote the advancement of mathematical and computational methods for solving problems arising in all disciplines encompassed by the Society. They place particular emphasis on numerical techniques for efficient computer applications to aid in the dissemination, integration, and proper use of computer codes, including preparation of computational benchmark and development of standards for computing practices, and to encourage the development on new computer codes and broaden their use.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

This panel will discuss topics related to the initial test program for first-of-a-kind (FOAK) advanced reactors. Dr. Sam Bays will provide a historical overview of past advanced reactor test programs as documented in his team's report, "Startup Physics Testing of Advanced Reactors - A Historical Review". Dr. Bays and Dr. Abe Weitzberg have co-chaired the ANS working group, Initial Fuel Loading and Startup Physics Tests for FOAK Advanced Reactors, ANS-19.13. Current findings of ANS-19.13 will be discussed. Dr. Nader Satvat of Kairos Power will be providing an overview of current test plans for the HERMES reactor. Mr. Mike Prible of Westinghouse will provide his perspectives leading the startup physics testing of AP1000 pressurized water reactors.
