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.

Terrestrial Energy, Schneider partner on molten salt reactor
Terrestrial Energy and Schneider Electric are teaming to deploy Terrestrial Energy's integral molten salt reactor (IMSR) to provide zero-emission power to industrial facilities and large data centers.
The companies signed a memorandum of understanding in April to jointly develop commercial opportunities with high-energy users looking for reliable, affordable, and zero-carbon baseload supply. Terrestrial Energy said that working with Schneider “offers solutions to the major energy challenges faced by data center operators and many heavy industries operating a wide range of industrial processes such as hydrogen, ammonia, aluminum, and steel production.”

The three-dimensional (3-D) VMEC code has been modified to model an energetic species with a variant of a Bi-Maxwellian distribution function that satisfies the constraint B[nabla][script F]h = 0, and the 3-D TERPSICHORE stability code has been extended to investigate the effects of pressure anisotropy in two limits. The lower limit is based on a purely fluid Kruskal-Oberman (KO) energy principle (ignoring the stabilizing kinetic integral), and the upper limit is obtained from an energy principle in which the hot particle pressure and current density refrain from interacting with the dynamics of the instability because their diamagnetic drift frequency is considered much larger than the dominant growth rate. We have specifically investigated the instability properties of a Heliotron device with a major radius of 3.9 m and total <> [approximately equal to] 3.9%, where the energetic particle contribution <h> varies from 0 to 1.3% for T
