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.

In most helical systems, electron-internal transport barriers (e-ITBs) are observed in electron cyclotron heated (ECH) plasmas with high heating power density. In the stellarator TJ-II, e-ITBs are easily achievable by positioning a low-order rational surface close to the plasma core because this increases the density range in which the e-ITB can form. Experiments with different low-order rationals show a dependence of the threshold density and barrier quality on the order of the rational (3/2, 4/2, 5/3 . . .). In addition, quasi-coherent modes are frequently observed before and/or after the e-ITB phenomenon at the radial location of the transport barrier foot. Such modes vanish as the barrier is fully developed.
