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.

At the USNRC from 1979 to 1986, as a technical reviewer, research engineer, and technical expert, Dr. Reyes led key regulatory safety improvements including: (1) resolution of the pressurized PTS issue and (2) revision of the ECCS rule for light water reactors. Dr. Reyes’s knowledge of thermal-hydraulics and his management of national laboratory projects were instrumental to this resolution. These regulatory achievements significantly affected the safe and continued operation of the commercial nuclear power plant fleet while ensuring public health and safety. During his academic career at Oregon State University (OSU) from 1987 to 2016, Dr. Reyes expanded the nuclear engineering program while distinguishing himself in education at both OSU and with numerous courses for the IAEA, as evidenced by his receipt of OSU awards for outstanding and inspired teaching as well as repeated involvement as an instructor for IAEA thermal-hydraulic courses between 2004 and 2013. His expertise in thermal hydraulics, heat transfer, and nuclear power plant systems scaled integral testing is world renown. In 2007, Dr. Reyes co-founded NuScale Power with the goal of completing the design, USNRC licensing, and deployment of a fleet of passive integral pressurized water small modular reactor (SMR) design. His involvement in an earlier DOE-funded project, MASLWR (Modular Advanced Small Light Water Reactor), became the progenitor for the NuScale SMR design. He is the co-inventor of this unique design. Evidence of Dr. Reyes’s creativity is demonstrated by the fact that he has 116 patents either granted or pending in 20 nations. Based on his vision of how this design would improve safety while providing economic nuclear power to the world, he successfully obtained investment funding from multiple sources. He tirelessly promoted NuScale, attracting more investors, especially Fluor Power and USDOE, and oversaw the design, construction, and operation of a scaled integral test facility for the SMR. Under his leadership, NuScale power grew from a two-person company to one with over 400 employees today. Dr. Reyes epitomizes and promotes, by example, the ingenuity and innovation that are at the core of the simpler and safer NuScale SMR design. Under his guidance, novel applications for the NuScale SMR have been confirmed including: hydrogen production, desalination, emergency power after natural disasters, mission critical facility powering, and power for remote or island communities. In 2020, the innovative NuScale design became the first and only SMR ever certified by the USNRC. The efforts leading up to this milestone involved the expenditure of approximately $1 Billion. NuScale now has important component technology partners and an agreement to supply the first plant at a site in Idaho for the Utah Associated Municipal Power System (UAMPS). The career of Dr. José Reyes encompasses a wide spectrum of outstanding contributions to nuclear technology including: regulatory issue improvements and resolutions; nuclear engineering education; advances in thermal-hydraulics, heat transfer and nuclear test facility scaling; and invention of a revolutionary new passive safe SMR design along with the creation of a company that has now achieved NRC design certification with near-term plans for deployment and changed the nuclear power plant landscape for carbon free energy. Dr. Reyes has pursued a career focused on the development and safety of U.S. and international nuclear power plant technology for over 41 years.
