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.

A series of 39 consecutive and repetitive discharges (Ip = 2MA, BT = 2.4T, <ne> = 3.8 × 1019m-3, gas rate ~1.5 × 1022 Ds-1 and with 2.8 MW of ICRH over a duration of 11s) has been performed in JET for a full day in order to study the particle retention behaviour as a function of the wall inventory and the global balance for a significant number of discharges associated to a high gas injection. Since the active pumping was achieved using the divertor cryopump only, its regeneration has allowed a direct calibration of the value of the pumped particle flux to be used in the particle balance analysis during the plasma operations for the "DOC-L" configuration. Taking into account the outgased flux between the discharges, the resulting wall inventory over the full day of operation is zero. During, the 11 sec of the ICRH power, about 8 % of the particles injected are retained in the machine equilibrated by a particle recovery between of 8% of the quantity injected. This shows that the gas released between pulses has been overestimated in previous JET gas balance analysis and that the particles trapped in the machine are localised in areas which are outgasing between the discharges.
