Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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 H (or D, or T) Sievert's constant for liquid Sn-Li alloys is calculated from thermodynamic data issuing of the Sn-Li binary phase diagram analysis. The range of temperatures investigated is 600-873 K (Sn0.8Li0.2 m.p. ~ 599 K) to maintain single-phase binary melts. The thermodynamic functions of Li-H, Sn-H, Sn-Li are evaluated to derive those of Sn-Li-H. Thus, monotectic solubility data for Sn and Li is analyzed. The calculation is done for high-dilution conditions. A quasi-chemical regular solution model is used for temperature/composition extrapolations when no data is available. The tritium Sievert's constant in Sn0.8Li0.2 at 600 K is: 9.65 10-8 Pa-12, five times the Reiter's measured value for Pb-17Li and ~ 6 times the value in Pb-17Li eutectic obtained by using the same theoretical approach.
