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.

Strontium: Supply-and-demand success for the DOE’s Isotope Program
The Department of Energy’s Isotope Program (DOE IP) announced last week that it would end its “active standby” capability for strontium-82 production about two decades after beginning production of the isotope for cardiac diagnostic imaging. The DOE IP is celebrating commercialization of the Sr-82 supply chain as “a success story for both industry and the DOE IP.” Now that the Sr-82 market is commercially viable, the DOE IP and its National Isotope Development Center can “reassign those dedicated radioisotope production capacities to other mission needs”—including Sr-89.

Irregularities in ICF shells need to be characterized in detail. Outside and inside surface, and wall thickness fluctuations are all Raleigh-Taylor unstable and can cause a shell to fail during compression. Until recently we could only detect outside surface profile fluctuations, measured along three mutually perpendicular great circles and displayed as line graphs. Measurements, paths, and display have all been upgraded to improve our ability to see fluctuations. We have added a Wallmapper that can determine thickness along the same paths as the surface profiles. The thickness data can be subtracted from the outer surface profile to give a (low resolution) inner surface profile. We have measured the surface profiles along up to 8 paths, and have displayed these profiles wrapped around the image of a sphere. With sufficient paths, this format gives a sense of the 2-D surface fluctuations on the shell. These additions should help us to understand the nature of shell defects and optimize our production processes.
