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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Hydrogen embrittlement behaviour of the reduced activation ferritic/martensitic steels, Eurofer'97 and VS3104, has been compared to that of the conventional alloy T91, by means of constant extension rate tests run under dynamic electrochemical charging. Charged versus uncharged reduction of specimen area ratios at rupture were taken as the most suitable ductility indexes for material discrimination in terms of hydrogen damage resistance. Fractographic analysis indicated that hydrogen content as low as 1.6 wppm caused rupture of al investigated steels, but to different degree, by promoting grain boundary decohesion. Higher hydrogen levels stimulated failure by the combined effect of bond strength weakening and stress intensification from dislocation blocking at interfaces. The better performances of T91 as well as the variability of Eurofer tensile responses were ascribed to the different chemistry and density of key microstructural factors, already suspected from metallurgical examination and further supported by hydrogen thermal extraction results.
