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.

College students help develop waste measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Both PF1A upper coils and lower coils experienced difficult situations during the National Spherical Torus Experiment–Upgrade (NSTX-U) machine operations in 2016. There are huge up-down electromagnetic forces on PF1A terminals, coil leads, and bus bars. Therefore, further analysis and additional reinforcement supports are needed to reduce the stress on the coil terminals and leads. Structural, thermal, and electromagnetic analyses of the three-dimensional PF1A lower bus bar and coil lead model have been performed using imported electromagnetic loads with the worst cases of 96 scenarios through the global Biot-Savart stick model. The reinforcement blocks for the PF1A lower coil leads and flags and two clamps were analyzed and installed for field testing. The coil leads and bus bars used in the field testing were qualified for the normal NSTX-U operating loads allowing similar reinforcement details to be used in the real NSTX-U machine.
