Live In-Person Meeting!

On behalf of American Nuclear Society Pittsburgh Section, Exelon Nuclear Generation and Westinghouse Electric Company, thank you for joining us for the 2022 International Conference on Physics of Reactors (PHYSOR) conference!

The conference will take place in Pittsburgh, Pennsylvania, USA on May 15-20, 2022. PHYSOR attracts international experts from all segments of the nuclear industry and scientific community, including vendors, utilities, laboratories, and universities. The theme for this year’s conference is Making Virtual a Reality: Advancements in Reactor Physics to Leap Forward Reactor Operation and Deployment.

As the nuclear industry continues to drive operational and economic performance improvements in current LWRs, and development and deployment of micro-reactors, small modular reactors and advanced reactors, continued innovation in reactor physics methodologies across a broad spectrum of topics is required. We have organized PHYSOR 2022 to cover a broad range of topics in thirty standard and special sessions tracks, and ten panel sessions. The conference also has ten half-day and full-day workshops planned (see Call for Papers).

Since the first PHYSOR conference in 1990, the conference has focused on reactor physics advancements and provided a platform showcase for pioneering concepts, methods, and products. As we leap forward to the future of nuclear technology, micro reactors, small modular reactors, advanced reactors, and high energy LWR fuel are at the forefront.

We look forward to joining together to celebrate reactor physics with the nuclear community in 2022!
