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.

Studies at Commissariat à l’Energie Atomique (CEA) have been under way for three years in an attempt to find methods for preventing and stopping denting. Tests have been performed in 28 model boilers (Ajax with U tubes and Clarinette with straight tubes). In these boilers, with continuous injection and blowdown, and heat flux is ∼40 W·cm−2 (126 900 Btu/ft2·h). The kinetics of denting has been studied with different levels of faulting. Some high-temperature electrochemical measurements established the mechanism of denting in the boiler tests. Denting kinetics can be rationalized in terms of three main parameters: faulting level, heat flux, and relative mechanical strength of the tube compared to the support plate.
