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.”

The initial design study of 28 GHz/35 GHz dual frequency gyrotron is presented. The design is based on 28 GHz 1 MW gyrotron which we have developed. And it is studied whether 35 GHz oscillation is possible or not using the present 28 GHz gyrotron cavity. From the numerical simulation results, the cavity can form 35.45 GHz TE9,4 mode oscillation of over 1 MW oscillation power with high efficiency. However, in the present mode converter and transmission mirror system, the radiated RF power through the output window is only about 70 % of the 35.45 GHz oscillation power because of the radiation angle difference of 15.85°. For more high efficiency operation for 35 GHz, we will re-design the cavity in which there are good candidate modes such that there is no radiation angle difference.
