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.

The neutronics performance of the EVOLVE concept was analyzed using two-dimensional calculations. The vapor fraction in the boiling blanket has a small impact on the nuclear performance parameters. For the worst case condition with the highest predicted vapor fraction distribution, all nuclear performance parameters are acceptable with a comfortable margin. The EVOLVE boiling blanket is expected to perform adequately from the neutronics point of view for any of the boiling regimes considered. Analysis was performed also for a preliminary design of the transpiration blanket option indicating that it will also have adequate nuclear performance parameters.
