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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

Bench scale methane cracking tests have been completed using a stack of ten SAES® St909 pellets. Baseline test conditions were five percent methane in helium at ten seem, 101 kPa (760 torr), and 700°C. Changes from baseline conditions varied temperature, pressure, flow rate, and carrier gas composition to include hydrogen and nitrogen. Methane cracking efficiency (ɛM) decreased with decreasing temperature and pressure. Faster gas feed rates decreased ɛM, but cracked more methane. Introducing hydrogen, nitrogen, or ammonia into the feed gas reduced ɛM, but ammonia was still cracked at high efficiencies. ɛM was further decreased when both nitrogen and hydrogen were in the carrier gas compared to using a carrier of only nitrogen or hydrogen.
