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.

Constellation seeks rezone for property adjacent to Illinois plant
While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use.

Molten salts have many applications in nuclear engineering, for example, pyroprocessing for used nuclear fuel treatment for which molten chloride salts are used, and molten salt rectors for which both chloride salt and molten fluoride salts are used. Materials corrosion is more challenging in these molten salt systems as the formation of the passivating oxide layer on the corrosion resistant alloys becomes thermodynamically less favorable. Materials corrosion in molten fluorides appears as bare alloy dissolution while the oxide layers formed in molten chlorides are typically porous, leading to the active metal dissolution in both molten fluoride and chloride salts. This restricts the use of many corrosion resistant alloys that rely on the passivating oxide layers. The present study conducted a critical review on materials corrosion in molten chloride and fluoride salts. The key environmental factors that influence corrosion in nuclear molten salt systems are discussed, including typical oxidants in the salt, fission product tellurium embrittlement, interactions with dissimilar materials, and temperature gradient. The historical development of corrosion resistant alloys for molten salt systems and recent attempts are also reviewed, and the effects of alloying elements and grain size were analyzed. One of the corrosion mitigation methods is to control the redox condition of the molten salt. Therefore, the study also analyzes the available redox control methods as well as the advantages and disadvantages of these methods. Finally, the current progress and challenges are summarized with an attempt at identifying the knowledge gaps and future research directions.
