2026 ANS Winter Conference & Expo in Phoenix, AZ

The American Nuclear Society's 2026 Winter Conference & Expo runs November 15–18 at the Arizona Grand Resort & Spa in Phoenix, Arizona, under the theme "Going Critical: Creating a Durable Nuclear Resurgence." It is one of the year's largest gatherings for professionals working across every facet of nuclear science and technology, from reactor design and fuel cycles to safety, regulation, and advanced research. The program combines plenary sessions, technical tracks, and an exhibition floor where vendors present equipment, services, and software for the nuclear sector. Embedded topical meetings expand the agenda: the International Congress on Advances in Nuclear Power Plants (ICAPP 2026), Advanced Reactor Safety (ARS 2026), and Advances in Thermal Hydraulics (ATH 2026). Attendees typically include engineers, utility and vendor representatives, regulators, national laboratory researchers, academics, and students. Sessions emphasize applied research, operating experience, and the deployment challenges facing both existing fleets and new reactor designs. Because the venue sits in the Phoenix metro area, most out-of-town participants stay at resorts and hotels near the Arizona Grand Resort & Spa or in downtown Phoenix, booking early given the size of the ANS Winter Meeting and the limited room blocks.
