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 computer program CRASH allows the calculation of triaxial stress and strain states in the sheath of cylindrical fuel elements when creep or plasticity occur in the cladding material. Any creep or plasticity law may be used in the program and any type of external stresses and strains assumed. A short description of the program is given in the first part of this paper. Its second part deals with some applications: examples of plastic thermal ratchetting under cyclic conditions and creep of cladding due to contact pressure are presented. These few examples show that the CRASH program is a useful and flexible tool for the cladding design of fuel elements. Moreover, its calculation time is sufficiently small as to allow intensive parametric studies.
