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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.”

Experiments on the Omega laser at the Laboratory for Laser Energetics require tantalum oxide (Ta2O5) aerogel thin films with a thickness ranging from 70 to 150 m and densities of 250 and 500 mg/cm3. Experiments have been done with the aerogel in a disk geometry with diameters ranging from ~2 to 3 mm with annular slots machined into it and without the slots. These experiments place demanding specifications on the targets in terms of thickness, dimensionality, and mass density variation. Future radiation experiments at the National Ignition Facility will require larger targets ~7 mm in diameter and 200 m thick with more complex features. In the past these targets have been conventionally machined from a starting billet of aerogel ~5 mm in diameter and height. Through a series of steps the aerogel was eventually machined down to the desired thickness. This was a long and arduous labor-intensive process that had high attrition rates and an overall yield of ~50%. We have improved this process by developing a new fabrication technique involving casting the foam to the desired thickness and then laser processing to create the desired features. This technique yields targets that meet the demanding specifications used in recent experiments while increasing throughput, yield, and available feature complexity in targets.
