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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

In order to generate a toroidal field in field-reversed configuration (FRC) plasma, a poloidal current drive by axial neutral beam injection (NBI) is investigated analytically and numerically. Species of neutral beam particle are hydrogen and helium. Feasibility for two types of injection geometry, injection along the geometric axis and to near the separatrix, is tested. Since all beam ions are lost directly through the device end, more than 12-kA beam current is needed to improve electron confinement near the separatrix. On the other hand, it is found that low energy (about 200 eV) beam ions can be confined for injection to near the separatrix. Present calculation of the beam ion orbit shows possibility of poloidal current drive and toroidal field generation by axial NBI into an FRC plasma.
