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.

To look for the signature of coherent multibody fusion, experiments of D-beam implantation were carried out using a highly preloaded TiDx (x = 1.4) target and a counter telescope of a E-E charged-particle spectrometer. As a result of the experiments, two unique particles were repeatedly observed, namely, 3He (4.75 MeV) and triton (4.75 MeV) from 3D fusion proposed by a new class of fusion theory in solids. The two unique charged particles were identified as products of the reaction channel of 3D to t + 3He + 9.5 MeV by the combinational analyses of one- and two-dimensional data. The experimentally obtained 3D fusion rate was of the order of 103 fusions/s, a surprisingly large value, which was enhanced ~1026 times compared with the traditional theory of random (noncoherent) D-D reaction and its sequential D-D-D reaction process.
