Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

The D-3He fusion reaction has been used to produce medical radioisotopes using the University of Wisconsin Inertial Electrostatic Confinement (IEC) Fusion Device. The high-energy 14.7 MeV proton generated from the reaction can activate materials for isotope production. The traditional IEC setup has been altered to generate medical isotopes using beam-target D-3He fusion. Beam target D-3He reactions in a thin-walled, water-cooled, stainless steel tube were used to create 13N, an isotope used in Positron Emission Tomography. At a maximum ion energy of 85 keV, 1.0 nCi of 13N was created as a proof of principle experiment. A scaled-up version of this concept may provide for a smaller, less expensive radioisotope generator for future commercial needs.
