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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Graphite-moderated thermal-spectrum subcritical reactors with a long diffusion path from neutron birth to absorption can be driven effectively from a neutron production target outside of the core, in contrast to the commonly accepted view that subcritical power reactors must have the source at the reactor center. Advantages of the external target include (a) elimination of the capital cost of a heavy magnet suspended above the reactor core, (b) elimination of safety concerns related to beam-induced damage from power failure in the magnet, (c) avoiding the disruption of the core to accommodate the neutron target, (d) the elimination of difficulties of access and removal of the target or fuel from the core owing to the magnet, and (e) the elimination of power peaking around the target and related high fuel burnup and materials damage concerns. There are also gains from driving a single reactor with two external targets instead of one.
