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.

Current boiling water reactors (BWRs) use active safety systems comprised of pumps, valves, motors, and diesel generators. These active safety systems (a) are a major cause of controversy in licensing power reactors because of reliability questions, (b) have high capital costs, and (c) require constant maintenance. An advanced BWR concept with passive emergency core cooling systems (PECOS) offers a basic alternative approach to reactor safety. In the PECOS-BWR, passive emergency core cooling is provided for the first 24 h by gravity flow of stored water released through fluidic valves that have no moving parts. Natural-draft air cooling removes heat from the core for longer periods.
