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.

A 2-MW, continuous wave, TE34,19 mode, 170-GHz coaxial cavity gyrotron for the International Thermonuclear Experimental Reactor (ITER) is under development within the European GYrotron Consortium (EGYC). This paper presents the improved design of the quasi-optical mode converter for this gyrotron. The simulation results show that with the improved quasi-optical mode converter, the fundamental Gaussian mode content of the rf beam can be enhanced to 99.1% at the output window plane and the stray radiation in the quasi-optical mode converter could be decreased to 1.2%.
