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.

A method and a laboratory facility were developed for the purpose of determining inflammation temperature of hydrogen-oxygen gaseous mixtures (HOGM). We have determined the inflammation temperature of HOGM containing the following impurities: Ar, Xe, H2O and tritium within the range of initial gas pressure from 3 to 13 kPa. The results agree well with the available reference and numerical simulation results. The inflammation temperatures of HOGM in the range of initial gas pressure from 2 to 13 kPa increases from 793 to 873 K. Average inflammation temperatures of hydrogen and deuterium mixtures differ no more than 1.6 %. Introduction of inert gases (argon and xenon) into gaseous mixture up to 45 volume percent does not change inflammation temperature significantly. Water introduction (in the range from 2.4 to 25 volume percent) does not cause gaseous mixture inflammation. The effect of tritium -radiation on temperature of GM inflammation within the range of tritium concentration concerned is insignificant and agrees with the results of numerical modeling obtained earlier.
