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.

Recently, the technical objectives of ITER were redefined aiming at a cost reduction of ~50% from the 1998 ITER design. Machine parameters that would satisfy the revised technical requirements under the engineering constraints were specified using a system code. The performances of the 1998 ITER and a redefined machine were studied and compared. As a result of these studies, final machine parameters were determined with revised conservative physics assumptions. This redefined machine is referred to as ITER-FEAT. It was shown that ITER-FEAT would achieve Q = 10 in inductive operation with reasonable and conservative assumptions. Also, with an efficient current drive system and modest confinement improvement, the possibility of Q = 5 noninductive operations in a steady state was shown.
