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.”

High heat flux components in fusion reactors will experience inelastic strains resulting from swelling, creep, and thermal expansion. Additionally, because of thermal and irradiation creep, the stresses will redistribute during the lifetime of the component. Current proposals for fusion first walls and divertors include structures fabricated by bonding two different metals together. The plasma side material is chosen to minimize sputtering; the coolant side material is chosen to maximize heat transfer. The structural response of such a design is not well known. Accordingly, a one dimensional inelastic stress analysis of a thin walled shell element has been performed. The stress analysis can include temperature dependent material properties, radiation induced swelling, thermal and irradiation creep, and thermal expansion. Furthermore, a simple equation has been derived for the case of a duplex plate constrained from bending. The stress distribution through the plate is followed with time. It is shown that the initial stress distribution evolves with time until some near steady state distribution is approached. The evolution is dependent on swelling and particularly on creep.
