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.

BWXT to demonstrate TRISO fuel line operations under contract extension
BWX Technologies announced on January 24 that it has been awarded a $4.9 million contract amendment to produce TRISO fuel particles using natural uranium and to demonstrate performance under a defined production schedule. BWXT’s Nuclear Operations Group will perform the work at BWXT’s Lynchburg, Va., facility, where TRISO production was restarted in November 2020. The contract amendment was awarded by Battelle Energy Alliance, which manages Idaho National Laboratory on behalf of the Department of Energy.

Calibration of an up-down type Mach probe is performed using a fast-flowing plasma produced by a magneto-plasma-dynamic arcjet. Mach probe data are compared with ion acoustic Mach numbers Mi, which are calculated using a plasma flow velocity Up and an ion temperature Ti measured by spectroscopy and electron temperature Te by Langmuir probe. The obtained data are also compared with Hutchinson's PIC simulation results in an unmagnetized plasma and are in good agreement with each other. First attempts to measure plasma flow field using a Mach probe are performed at the open-end section in GAMMA10. It is found that Mi at r=0 is more than 2, namely a supersonic plasma flow is formed in the end-cell region.
