Researchers at Lawrence Livermore National Laboratory (LLNL) have successfully observed and characterized the initial stages of hydrogen-uranium corrosion, a significant advancement for understanding metal-hydrogen degradation reactions. This knowledge is vital for enhancing the durability of plasma-facing components in fusion energy, improving hydrogen storage reliability, and increasing the efficiency of nuclear fuel cycles. The team employed a non-destructive imaging technique called white-light interferometry, allowing them to monitor the uranium surface in a hydrogen environment without damaging the material. They discovered that when hydrogen interacts with uranium, it forms uranium hydride, which increases internal pressure and leads to surface blisters that eventually burst. Notably, the corrosion spread horizontally rather than vertically, contradicting existing models. The researchers plan to extend their studies to broader conditions and explore applications in other fields, such as hydride superconductors and industrial metal corrosion, ultimately aiming to develop more accurate predictive models for uranium degradation.
