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.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.

This work presents the results of measurements of the effective thermal conductivity of Li2O and Be pebble beds using a hot wire method1. Also, preliminary results for a binary bed using Al2O3 pebbles are presented. The measured value for an Al2O3 single packing bed showed good agreement with Schulunder's correlation2 and Hall-Martin's correlation3 with a contact area fraction of 5 × 10−5. The value of the contact area fraction in this study showed consistency with that reported by Dalle Donne et al.4. Results for the binary bed of Al2O3 (0.3 mm and 3 mm) pebbles showed good agreement with the same correlation using the same value of contact area fraction. The measured value of the effective thermal conductivity for an Li2O bed using 1 mm pebbles agreed with the correlation using a value of 4.9 × 10−3 for the contact area fraction. The measured values of the effective thermal conductivity for 0.6 mm and 1mm Be pebble beds showed consistency with the correlation using 1 × 10−4 for the contact area fraction.
