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.

INL’s new innovation incubator could link start-ups with an industry sponsor
Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

A high-breeding fast reactor with fission product gas purge/tube-in-shell metallic fuel assemblies is proposed. Its reactor doubling time is <10 yr because fast reactors must have economical fuel breeding as well as economical electricity generation. The core has a high volume fraction of fuel (>50%) and realizes a very hard neutron spectrum. Thus, a fast-breeding 670-MW(electric) reactor with a high breeding ratio (1.84) and a short reactor doubling time (6.7 yr) is proposed. The structure of the fuel assembly, its fabrication, and the fission product gas purging mechanism are assessed and the new fuel assembly concept is determined to be feasible. Purging of the fission product gas does not affect the shielding requirement and can be managed by a small-scale cover gas treatment system because of the good fission product retention characteristics of the sodium in the fuel assemblies. The entire reactor configuration, including the intermediate heat exchangers, was assessed utilizing conventional reactor components.
