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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

This paper presents the results of experiments and analyses to quantify the chemical reactivity of plasma-sprayed (PS) Be specimens exposed to steam. Test specimens with densities of 94% theoretical density (TD) and 92% TD were prepared by a low-pressure-plasma-spraying (LPPS) technique. Sample density, porosity and specific surface area were measured using immersion density and gas-adsorption techniques. Microstructural characterization was done using optical and electron microscopy. Hydrogen generation rates were obtained from tests of specimens in steam at temperatures from 350 to 1000°C. Below 700°C, hydrogen generation rates for the 94% TD material were somewhat higher than rates for 100% TD Be, but they were substantially lower than rates for the 92% TD Be and for previously tested PS-Be and porous Be. Reaction rate differences correlated with specific surface area differences for the materials tested.
