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.”

Electromagnetic drift instabilities are considered for tandem mirror and field reversed plasma configurations taking into account effects of magnetic drift and finite ( = plasma pressure / magnetic pressure). Stabilization of drift modes due to finite plasma length along magnetic field lines is studied. Dispersion equation includes effects of the common actions of gradients of plasma density, ion temperature and electron temperature with no assumption of adiabatic response of ions or electrons for the ranges of perpendicular wave number values from k[perpindicular] < 1/Ti up to k[perpindicular] ~ 1/Te (Ti and Te are ion and electron thermal gyroradiuses). Instability induced turbulent transport is considered for mirror and field reversed magnetic configurations. Effect of sheared E × B flow on fluctuation level and transport is discussed.
