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.

Forecasting of changes in the physical properties of steels under irradiation is usually achieved through a detailed knowledge of the source in terms of atomic displacements. This source is extended to the secondary and tertiary atoms of the cascade, with Lindhard’s inelastic collision description. On this basis, it is possible to establish a model for the creation of “displacement zones” by evaluating their effectiveness through a nonoverlapping criterion between zones. The A 533 B steel yield strength increases after irradiation at 100°C (373 K) in two different spectra (Saclay—H2O at Osiris, D2O at EL.3) made it possible to compare the efficiency of this model with existing ones. Furthermore, preparation of the model leads to a normalized damage function closely approaching the one hitherto recommended by Euratom.
