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 N Reactor is equipped with 12 horizontal U-tube steam generators. Originally, these contained Type 304 stainless-steel tubes. From 1964 through 1971, ten were retubed with Inconel-600 tubes because severe stress corrosion cracking was experienced in stainless-steel tubes. Tube performance is monitored by eddy-current examinations, tube removals for destructive examination, and checking for radioactivity in the secondary system. The results of this program show that no significant corrosion has occurred in the Inconel-600 tubes in 11 yr of service. Five tube leaks have occurred in the two remaining units with Type 304 stainless-steel tubes over the same period.
