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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

Magnetohydrodynamic flows play an important role in the design of liquid-metal fusion reactor blankets. The interaction of the plasma-confining strong magnetic field and the electrically conducting coolant and breeding material may cause high pressure drop and unusual flow structures compared with hydrodynamic flows. In strong magnetic fields, duct flows exhibit a core where viscous effects are unimportant, while all flow variables are matched to the boundary conditions within extremely thin layers. In the inertialess inductionless limit, the governing equations can be reduced to a set of coupled two-dimensional equations for pressure and potential through analytical integration in the core and the layers. The use of curvilinear boundary-fitted coordinates leads to a unique numerical procedure for flow calculations in arbitrary geometries. The wide range of possible applications is demonstrated by some examples.
