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.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.

Dynamic behavior of cryogenic distillation columns has been studied with an H-D-T system (1.5 g of tritium) under single column and two-column cascade operation modes. The columns used were different in inner diameters (1 cm and 2 cm) and in size packings (3 mm Dixon rings for the larger column and 1.5 mm Dixon rings for the smaller column). For both of the columns, the experimental observations for composition distribution at the steady-state was in close agreement with calculated results for all the components. The HETP values measured were in the range from 3 to 6 cm. The dynamic variations of compositions in bottom product streams experimentally observed were well predicted by computer-aided simulation. For top product streams, the variations were significantly slow in comparison with those of the calculated results using an assumption that liquid holdups in condensers were negligible. These results indicate that the columns have appreciable liquid holdups at the condensers.
