Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

In an international industry, regulators cross the border too
Since nuclear physics works the same in Ontario as it does in Tennessee, the industry has been trying to create a reactor that can be deployed on both sides of the border. Now, the Nuclear Regulatory Commission and the Canadian Nuclear Safety Commission have decided that some of their rulings can cross the border too.

Our increasing need for safe, abundant, reliable, and carbon-free energy sources is stimulating renewed interest for employing nuclear energy to power our world. New materials and technologies that can address sustainability, cost, and waste issues of current water-based reactors is critical for realizing a future powered by the atom. Among these concepts is the utilization of molten salts as both the reactor coolant and as a fuel solvent, namely, the molten salt reactor (MSR). This workshop will provide an overview of the MSR concept and current technological challenges facing its development and deployment. On the experimental side, we will compare classical approaches to molten salt characterization with modern-day developments, with an emphasis on laser-based diagnostics. We will discuss the challenges associated with the modeling and simulation (M&S) capabilities, introduce the important physics spaces relevant to various MSR designs, and discuss the tight coupling of single physics modules to enable multi-physics simulation of the core and system.
