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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Irradiation of polymer-based directional dry adhesives with gamma photons has been performed. This irradiation is commensurate with the radiation that an adhesive sample would be exposed to if deployed in a nuclear glove box or other high-radiation environment. Before and after irradiation, samples were tested using a three-axis adhesive testing stage and were analyzed via a scanning electron microscope and a water droplet contact angle analyzer. At doses in excess of 270 kGy, the adhesive performance began to deteriorate, continuing to an overall performance reduction of 55% at a dose of [approximately]500 kGy. Significant changes in the surface energy of the bulk polymer are also indicated by changes in water droplet contact angles, contributing to the adhesion performance loss. Such analyses allow for quantitative statements to be made about the expected performance of these adhesives when deployed in high-radiation environments.
