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.

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.

A survey of large scale DT tokamak design studies shows that the confinement time required to achieve self-sustaining operation can be much less than that predicted by the recently reported neo-Alcator scaling. The excess containment is, in most cases, more than an order of magnitude larger than that required for a steady-state burning plasma. If neo-Alcator sealing remained valid to reactor conditions, means must be found to reduce confinement times to levels consistent with steady-state operation. The problem of excess confinement has not been addressed adequately in the available literature. A positive aspect is that this excess confinement is likely to be available without engineering or physics penalty. A constructive use to which this excess confinement can be put is to burn advanced fusion fuels instead of the DT reaction, and thereby reap the practical benefits of reduced energetic neutron fluxes.
