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.

Fabrication milestone for INL’s MARVEL microreactor
A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy (DOE-NE) recently visited Carolina Fabricators Inc. (CFI), in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance (BEA), which manages INL, awarded the CFI contract in January.

A liquid-metal fast breeder reactor (LMFBR) differs from a light water reactor in that it has a much lower internal pressure and a significantly higher operating temperature. These divergent design conditions lead to a special design concept and require specific efforts in fabrication and installation. Important features in design, analyses, fabrication, and installation of LMFBR thin-walled piping systems had to be developed or standards had to be modified. They were accomplished in the KKW Kalkar project. All final checks, including leak tests and pressure tests of the primary and secondary systems, have met the requirements. The installation of the KKW Kalkar pipeworks was finished with the filling of sodium into the last main system in April 1985.
