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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Heat transfer to liquid lithium in the presence of a transverse magnetic field and a gravity field was analyzed in a square cross-section duct. The duct had conducting vanadium walls. Magnetohydrodynamic equations in three dimensions in the Cartesian coordinate system were solved. First, the Nusselt number was calculated with no magnetic field and a gravity field. Second, the Nusselt number was calculated for the case of a transverse magnetic field acting on the fluid. Third, the Nusselt number was calculated for the case of a transverse magnetic field and a gravity field acting on the fluid. Only one face of the channel was heated. It was found that the Nusselt number is not sensitive to application of a gravity field and is sensitive to application of a transverse magnetic field and it decreases when a transverse magnetic field is applied. It is observed that when the intensity of the transverse magnetic field reaches 0.11 T, further reduction in the value of the Nusselt number almost stops.
