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.

Terrestrial Energy, Schneider partner on molten salt reactor
Terrestrial Energy and Schneider Electric are teaming to deploy Terrestrial Energy's integral molten salt reactor (IMSR) to provide zero-emission power to industrial facilities and large data centers.
The companies signed a memorandum of understanding in April to jointly develop commercial opportunities with high-energy users looking for reliable, affordable, and zero-carbon baseload supply. Terrestrial Energy said that working with Schneider “offers solutions to the major energy challenges faced by data center operators and many heavy industries operating a wide range of industrial processes such as hydrogen, ammonia, aluminum, and steel production.”

Chalk River Unidentified Deposit (CRUD) specimens were sampled and analyzed using an electron probe micro analyzer (EPMA; JEOL JXA-8230R) with a bundle of spent nuclear fuel (actual burnup 49 655 MWd/tonne U) from a Korean nuclear power plant. CRUD collection in the reactor refueling cavity was carried out using the following two methods. The first method used an Al2O3 scraper to scrape a specific area of the fuel cladding and then a paper filter to draw the suspended pieces around it. The second method removed CRUD deposited outside the cladding by vibrating the fuel bundle with an ultrasonic wave. In the first method, scraping some parts of the fuel rods with the Al2O3 scraper made it difficult to obtain an analytical sample because of the very small sample collection. However, the results of the analysis of the identified CRUD samples accurately confirmed the shape and composition of the CRUD in the specific area of the fuel rods desired by the user. In contrast, the second method using the ultrasonic cleaner made it very difficult to analyze samples because of the excessive amount of collected CRUD. In this study, we will discuss two methods for collecting corrosion products existing in the primary cooling system of a pressurized water reactor and the results of an analysis using a shielded EPMA. In addition, we will confirm the value of the Ni/Fe ratio.
