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.

Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

To improve the efficiency of gas chromatography for hydrogen isotope separation near room temperature, feasibility of new columns was examined for H-D and H-D-T mixture gases. One kind of the column was the mixture of Pd-Pt alloy and Cu powders as the previous study. But special attention was paid for preparing the separation column; Pd-Pt alloy particles below 200 mesh was mixed with copper powder of 150–200 mesh and packed into a loading tube of stainless steel as uniform as possible. The separation for H-D mixture gases could be remarkably improved by this column even at temperatures around 300 K. This column also could separate tritium as T2 from H-D-T mixture gas containing only 0.13 % T. The other column was prepared by Pd-Pt alloy supported by porous SiC powder for economical use of the expensive alloy. Although this column gave similar separation chromatograms, the separation efficiency was still insufficient and further studies are required.
