Nuclear News 40 Under 40—2025
Last year, we proudly launched the inaugural Nuclear News 40 Under 40 list to shine a spotlight on the exceptional young professionals driving the nuclear sector forward as the nuclear community faces a dramatic generational shift. We weren’t sure how a second list would go over, but once again, our members resoundingly answered the call, confirming what we already knew: The nuclear community is bursting with vision, talent, and extraordinary dedication.

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.
