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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.”

In this paper we present and discuss recent experimental and theoretical advances concerning the redistribution process, the control of target temperature, and the effect of deuterium-tritium (D-T) aging on the optimum laser shot temperature at the Laser Mégajoule (LMJ) facility.We introduce two analytical models to provide a better understanding of thermal target behavior. On one hand the first model describes the evolution of the D-T layer temperature, which cannot be recorded experimentally. On the other hand the second model highlights the necessity for the optimum laser shot temperature (i.e., 1.5 K below the triple point) to be adapted to the aging of the target.The analytical considerations are completed with experimental results obtained with D2 taken as a reference system to investigate the properties of D-T in LMJ targets.
