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.

A shielding analysis of the IGNITEX device proposed by the University of Texas as a relatively inexpensive way to obtain an ignited plasmas has been performed. This paper emphasizes the radiation streaming effects on the radiation environment in the IGNITEX machine. The analysis was done by using a three-dimensional Monte Carlo code, MCNP, along with a one-dimensional discrete ordinate code and simple analytical formulas. The results show that the streaming effect on the global radiation in the test cell is not significant. The vacuum and maintenance penetrations, in particular, straight ducts, increase the radiation level at and near the outlet of the ducts considerably. The vacuum fuel processing and fueling rooms should be specifically shielded from the test cell. Access during the pulses must be limited since the radiation level in these areas is very high during D-T burning pulses because of the radiation streaming from the test cell.
