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 Stein Industrie steam generator of the 250-MW(e) demonstration fast breeder reactor Phenix comprises three units. Each unit is divided into 12 evaporator modules, 12 superheater modules, and 12 reheater modules. Twenty-four evaporators are made of 2¼ Cr—1 Mo ferritic steel and 12 are made of 2¼ Cr—1 Mo—1 Nb stabilized ferritic steel. All superheaters and reheaters are made of 321 austenitic steel. Since Oct. 1973, this steam generator has been submitted to a number of startups and shutdowns and some 9000 h of operation at full load without any leak, with an acceptable hydrogen diffusion rate of 0.25 g/h per unit through the single wall of the tubes. The Fives-Cail Babcock steam generator selected for the 1200-MW(e) Fast Breeder Power Plant Super Phenix is comprised of four modules with a 357-tube helical bundle made of Alloy 800 housed in a shell made of an austenitic steel (Type 304 or 316L). The module is rated at 750 MW(th) and weighs 140 tons. Other steam generators made of ferritic steels are considered in the longer range for power plants beyond Super Phenix.
