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.

The energy spectra and angular distributions of the proton emission from the 93Nb(n,xp) reaction are measured by means of the multitelescope system at the University of Science and Technology of China. The total proton production cross sections are in fair agreement with the results obtained by other groups. The energy spectrum is explained well by the sum of the spectra calculated on the basis of the pre-equilibrium and Hauser-Feshbach theories. There are deviations from a previous measurement of the high-energy end of the angle-integrated proton spectrum. The angular distribution, which shows a strongly energy-dependent forward-backward asymmetry, is in fair agreement with the Kalbach-Mann phenomenological model.
