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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Heat transfer in magnetohydrodynamic flow of a liquid metal in rectangular ducts with thin conducting walls in the presence of a large transverse magnetic field is examined. A significant fraction of the fluid flow, in the form of high velocity jets, is confined within the boundary layers (side layers) adjacent to the side walls which are parallel to the magnetic fields. The existence of the high velocity jets may drastically enhance the cooling capacity. Two schemes - integral and explicit - for the treatment of the flow in the side layers are discussed. Heat transfer calculations based on these schemes are compared. Work supported by the U.S. Department of Energy/Office of Fusion Energy.
