Building momentum for a stronger ANS
Hash Hashemianpresident@ans.org
The 2025 ANS Annual Conference in Chicago was a powerful springboard to begin my term as president. With over 1,400 attendees, it was one of our most dynamic gatherings in recent memory—full of energy, ideas, and a shared commitment to advancing nuclear science and technology.
As we move forward, my focus is clear: to elevate the role of nuclear in environmental protection, national security, energy diversity, and grid stability. These priorities are not just strategic—they are essential to a cleaner, more resilient future.
The goals I laid out at the conclusion of the Board of Directors meeting in June are simple, but I am sure they will be effective in engaging our community.
One simple change to start is the move away from the term meetings—the American Nuclear Society now uses the term conferences to describe its two yearly flagship gatherings, to more appropriately reflect the more than 1,000 attendees that these events bring together.
