Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

The chemical reaction behavior of B4C absorber material with stainless steel 1.4919 (Type 316) and Zircaloy-4 is studied in the 800 to 1600 C temperature range. The reaction kinetics for both systems can be described by parabolic rate laws. Above 1000°C, the reaction zone growth rates in the B4C/stainless steel system are about two orders of magnitude higher than those in the B4C/Zircaloy-4 system. The compatibility specimens are quickly and completely liquefied at temperatures ≥1250°C for the B4C/stainless steel reaction couples and temperatures ≥1650°C for the B4C/Zircaloy-4 reaction couples. In both reaction systems, liquefaction occurs below the melting points of the components.
