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.

In the JT-60 neutral beam injectors (NBIs), an active method using a set of coils is adopted to shield unneutralized beams from stray magnetic fields, while the usual passive method using high-mu materials is used to shield the ion sources and neutralizers. This active shielding method is a unique solution for the unneutralized beams in the JT-60 NBI under the constraints of the limited space available and minimizing the error field induced by the shielding. A passive shielding method is permissible for the ion sources and the neutralizers because the space to be shielded is limited. The active shielding system is designed by making a one-fourth model of the magnetic system and calculating ion orbits using magnetic fields measured in the model. The shielding characteristics are checked by arrays of thermocouples buried in the beam dump where the unneutralized beams are thermalized. The thermocouple outputs are consistent with those predicted from the ion orbit calculations.
