2024: The Year in Nuclear—July through September
Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from July through September 2024.
Stay tuned for the top stories from the rest of the past year.

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.
