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.

Rex D. Geveden is president and chief executive officer of BWX Technologies, Inc. (BWXT), a $2.5B nuclear technology and manufacturing company headquartered in Lynchburg, Virginia. As CEO, Mr. Geveden directs all business operations and leads strategic planning, capital allocation and leadership succession.
BWXT manufactures nuclear reactors, fuel and components for the U.S. Navy; provides nuclear technical services at contractor-operated Department of Energy and other U.S. government laboratories and facilities; develops and manufactures microreactors for national security and space applications; and processes special nuclear materials and advanced nuclear fuels. BWXT also manufactures medical radioisotopes and supplies precision manufactured components, services, and fuel for the commercial nuclear power industry.
With about 8,000 employees, BWXT has 14 major operating sites in the U.S., Canada and the U.K. comprising over four million square feet of manufacturing space. In addition, BWXT joint ventures operate at a dozen U.S. Department of Energy sites and two NASA facilities.
Mr. Geveden joined BWXT in 2015 as chief operating officer (COO) before advancing to CEO in 2017. Previously, he advanced to the position of executive vice president at Teledyne Technologies over an eight-year period, ultimately leading the Digital Imaging and Engineered Systems segments of the business.
He spent 17 years at NASA, including service as the agency’s COO responsible for a $16 billion portfolio of work in NASA’s mission areas of science, aeronautics, space operations and exploration along with oversight of NASA’s 10 field centers.
Mr. Geveden chairs the board of TTM Technologies, Inc., a global electronics manufacturing company. He holds bachelor’s and master’s degrees in physics from Murray State University.
