Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.”

To learn more about liquid metal distillation as it might be applied to nuclear fuel recovery and reprocessing, liquid metal distillations involving the tin-zinc, cadmium-bismuth, and indium-zinc binary systems were conducted in an evacuated chamber. An x-ray fluorescence spectrometer provided a continuous chemical analysis of the distilling surface during each run. This information was used to evaluate the validity of various theories and assumptions concerning surface depletion, oxide contamination, and turbulence effects. The existence of a large surface depletion effect in nonturbulent metal distillations was proven. However, the level of turbulence necessary to eliminate concentration gradients was found to be much lower than that assumed by some designers of commercial equipment. The presence of surface oxides was often an important factor in determining the enrichment and rate of distillation. The Langmuir-Knudsen theory was shown to be unreliable when liquid diffusion or surface oxide resistances were significant. A more complete approach involving the principles of transport phenomena was developed. An analytical solution was derived for the nonturbulent case and was tested using the spectrometer data.
