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.”

Adaptive control techniques can be applied to online gain tuning of tokamak thermokinetics. Here, a self-tuning control scheme is explored for both the plasma profile and power control. The distributed parameter system of the flux-surface-averaged one-dimensional transport equations is discretized by a nonlinear variational procedure. A finite-dimensional multiple-input/multiple-output control algorithm is derived using the linearized equations. A particular class of nonlinear three-parameter profiles is used for plasma density, temperature, and deuterium fraction profiles. Feedback gains are determined using a simplified minimum variance control law of self-tuning control. In the examples, normal multiple-output specifications for the plasma profile parameters for the density and power control are shown to be controllable by multiple-particle inputs alone.
