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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.”

An all-welded ITER divertor Langmuir probe (DLP) model was analyzed by ANSYS 17.0. Temperature field and surface convective heat transfer were obtained by fluid analysis using ANSYS/CFX under both steady-state (10 MW/m2) and slow transient-state (20 MW/m2 for 10 s) working conditions. Mechanical analysis was performed with the temperature field as the preloading condition. The equivalent von-Mises stress and plastic strain distribution have been obtained. The analyzed results show that the DLPs would withstand very high temperature, which can reach 1852°C mainly owing to the extremely high heat flux as well as photon irradiation. The maximum temperature of the copper connection between the DLP and the monoblock would be 792°C, demonstrating that the bonding structure would not be destroyed. All the materials except the alumina pipe have undergone plastic yield analysis, implying that a low cycle strain-fatigue analysis needs to be done in the near future.
