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.

ANS holds Educator Training webinar on nuclear waste
Loewen
Perfetti
A recent American Nuclear Society webinar tackled misconceptions about nuclear waste. Christopher Perfetti, an associate professor of nuclear engineering at the University of New Mexico, presented “The How, Why, and Where of Nuclear Waste,” the latest online event in ANS’s Educator Training series.
Moderated by ANS past president Eric Loewen (2011–12), this presentation was built to be an accessible and informative Nuclear Waste 101 offering as part of the Society’s broader effort to develop a program specifically tailored to educating K-12 teachers.
