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.

Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

The flute instabilities were investigated in the GAMMA10 A-divertor magnetic field with help of computer simulations. The basic equations used in the simulation can be applied to only an axisymmetric system. So the high pressure in the remaining non-axisymmetric anchor cell, which is used for the flute mode stability, is taken into account by redefining the specific volume of a magnetic field line. It is found that the minimum-B mirror can stabilize a flute mode even in a divertor mirror cell, but its stabilizing effects are weaker. The radial transport accompanied by the flute instabilities in the GAMMA10 A-divertor is found to be rather smaller than that without a divertor mirror cell.
