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.

With higher labor costs compared to other generation fuel sources, Nuclear Plants are highly incented to maintain reliability during operating cycles, making the most of every hour generating electricity. Over time, the industry has realized reliability today is driven by investment decisions made years in the past through long range planning. Aging and obsolescence issues may take decades to develop into current threats to reliability. If there were no limitations on funding, human resources, or capacity factors, maintaining reliability would not be such a challenge. However, having limitations in all these areas, licensees are forced to make sound investment decisions many fuel cycles into the future. The importance of these decisions is even more relevant when Subsequent License Renewals are at stake. This session will present approaches to optimize future capital investment including the extended horizons of Subsequent License Renewals. The panel will discuss the challenges of “complete discovery” and the value of portfolio optimization.
