LLNL Simulates Nuclear Fallout at 8,540°F, Revealing Cesium Condenses Later Than Uranium

Summary
Lawrence Livermore National Laboratory used a plasma-flow reactor to recreate one stage of nuclear fallout formation, heating cesium, uranium and cerium to about 8,540°F without triggering a nuclear reaction.
Two cooling paths—continuous cooling and delayed rapid cooling—showed uranium and cerium condensed quickly, while cesium condensed later and mixed more readily with other elements when kept hotter for longer.
That behavior gives researchers a clearer picture of how fallout particles form and disperse after a nuclear event, improving models used for emergency planning.
The findings could also aid nuclear forensics by helping investigators trace debris patterns and infer the conditions behind past nuclear detonations or accidents.
