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.

An overview is given of the research carried out by the French Atomic Energy Commission on the geological disposal of nuclear waste. Recalling the new legal framework of these studies, the specific methodology of this field, which relies on the association of laboratory and in situ experiments, natural analogues, and modeling is emphasized. Next are underlined the basic questions, which have to be reliably answered when one wants to predict the behavior of the repository and the fate of the most radiotoxic nuclides, in particular over very long time spans: What parameters govern the hydrodynamics and the geochemistry of the system? What are the processes controlling the degradation of the different technological and natural barriers, as well as the release, migration, and retardation of radionuclides through the geosphere? For each of these issues, the current programs of research are described and indications are given about significant achievements.
