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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

High-temperature strength, weldability, and decarburization behavior in liquid sodium of 2¼ Cr— 1 Mo steel with a wide variety of heat treatments and some carbon stabilized 2¼ Cr—1 Mo steels are examined for the purpose of material selection of liquid-metal fast breeder reactor (LMFBR) steam generator tubes. Decarburization of 2¼ Cr—Mo steel in sodium can be suppressed when it is appropriately normalized and tempered instead of annealed. The 2¼ Cr—1 Mo—Nb—Ni steel is considered to be preferable to other stabilized steels, since a small addition of nickel assures sufficient strength, even if the normalizing temperature is as low as 950°C. Stabilized steels should be welded carefully to obtain a fully penetrated bead. Preheating above 200°C and postheating above 720°C are required for stabilization. Compared with all the investigated properties, the materials recommended for LMFBR steam generator tubes are normalized-tempered 2¼ Cr— 1 Mo steel and, if decarburization is not allowable, 2¼ Cr—1Mo—Nb—Ni steel, with the condition that a sound-welded joint can be available.
