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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The RFX experimental results at the highest plasma current (about 1 MA) and for relatively long pulses (150 ms) show the presence of high power flux densities on the first wall, up to 40 MW/m2 averaged on a single tile.
Detailed numerical analyses have been carried out to simulate the thermal response of a single tile. The results of sensitivity analyses give information on the radiative and convective power flux intensities and the related first wall temperature distributions.
The experimental data and the results of thermal analyses give quantitative information and qualitative guidelines for the design of an optimized first wall for a RFP device.
