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.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

Use of the curvature drift or the E × B drift of ions is studied in order to separate fusion protons from thermal components escaped from a FRC/D3He reactor. Orbital calculation is carried out to examine modulation, bunching, trapping and deceleration of the proton beam in a Traveling-Wave Direct Energy Converter (TWDEC). Results of numerical calculation show that energy conversion rate of the TWDEC increases up to 0.8 as a result of improvement of beam modulation. Computer simulation using a beam-circuit code clarifies desirable performance characteristics of the TWDEC
