Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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 potentiality of a new type of flowmeter, intended to measure the coolant flow rate through a fuel assembly of a nuclear reactor, was investigated. This new type of flowmeter, the nuclear turbine flowmeter, has the advantage that no extra signal wires are needed; the signal can be read by a neutron detector positioned in its vicinity. The influence of a rotating test turbine (installed in a setup at the Hoger Onderwijs Reactor in Delft, The Netherlands) on the signals of several neutron detectors was analyzed. From the results, it appeared that the rotation frequency of the test turbine could easily be detected by all neutron detectors used. The influence of the rotating test turbine on the signals of detectors positioned nearby is strong compared with the background noise level found for in-core neutron detectors in boiling water reactors.
