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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

The release behavior of uranium, plutonium, and neptunium from a defense waste reference glass was studied at 90 °C, alone and in the presence of ductile iron. Deionized water and simulated groundwaters for repositories in basalt and salt were used as test solutions. The initial surface area of glass to volume of solution was 10 m−1; the surface area of iron, where included, was equal to that of the glass sample. Solution samples were removed at regular intervals over 56 days, and actinide concentrations in unfiltered and 1.8-nm filtered (i.e., dissolved) portions were analyzed. The release behavior of uranium, plutonium, and neptunium did not show any consistent relationship to each other in any of the solutions, casting doubt on the use of uranium as a “master” indicator of actinide release. The presence of iron increased the initial rate of actinide release from the glass for all solutions, although the concentration of truly soluble actinides decreased. The difference is attributable to the formation of colloidal actinides. The actinide concentration in the filtered samples closely approaches the known solubility concentrations for hydrate oxides of these elements, suggesting a solubility-limiting control to the release of actinides from glass for time periods greater than several months.
