ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.”

A 21S metastable helium atomic beam injector was studied for a beam probe of electric field diagnoses, which is applicable to high electric potential region in Inertial Electrostatic Confinement Fusion (IECF) plasmas where a solid probe can hardly be utilized. With deuterium background gas (~0.1Pa) which is the minimum operation pressure of the IECF devices, the beam density was found to decrease ten times lower than beam density without background gas because of collisional effect. Also, plasma parameters in a-magnetron-discharge-based exciter were evaluated by means of Langmuir probe and emission spectroscopy. These results strongly imply a high excitation rate of ~10-4 into 21S metastable state.
