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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

A methodology is developed to measure the adhesion force and the work of adhesion between aerosols generated in very-high-temperature reactors (VHTRs) and interacting with structural materials. The method uses an interactive system of a silver particle interacting with Haynes 230 (H230) surfaces, compares the measured data with theoretical values, and uses an atomic force microscope in an air environment glove box with ambient temperature of 20.27°C and relative humidity of 34.97%. The adhesion force data are obtained for a silver particle interacting with H230 under four different surface conditions including “as received” and after oxidation for 5, 10, and 15 min, respectively. It was found that the JKR (Johnson-Kendall-Roberts) theory predicted values that were up to three orders of magnitude higher than the experimental data. In contrast, the inclusion of surface roughness from both the particle and H230 samples in the calculations produced results that are one order of magnitude higher than the experimental data. These comparisons provide insight into the significant influence that surface roughness has on adhesion force. A range of values of 0.02 to 0.3 μN was obtained from the adhesion force distributions of measured data that can be used as bounds on forces that can be produced in a silver-H230 interactive system.
