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.”

Taking into account Einstein’s general theory of relativity, a modification of Lockheed’s compact fusion reactor concept is proposed by replacing the two superconducting tori with rapidly rotating tori rotating in opposite directions. According to the general theory of relativity, two Coriolis force fields in opposite directions are set up, both of them having a negative mass density in their corotating reference systems, with a vanishing negative mass density in the center in between the rotating tori, where the hot fusion plasma is centered. Because of the Nernst effect going in the opposite direction, large toroidal currents are set up, repelling the hot plasma from the much cooler tori. This results in closed magnetic field lines for stable plasma confinement. The remaining problem, the removal of the heat released by neutron absorption in the metallic tori, can be resolved by a pulsed operation, axially injecting cool deuterium-tritium gas, from which the heat is externally removed by a radiator.
