Radiation Damage in Fusion Materials

Radiation damage in fusion materials refers to the harm caused to materials used in fusion reactors due to high-energy particles generated during nuclear fusion. In fusion, light atomic nuclei combine to form heavier ones, releasing neutrons and other particles. These high-energy particles can displace atoms in the reactor’s structure, creating defects and weakening the material over time. This damage can lead to reduced structural integrity, impacting the reactor's safety and efficiency. Understanding and mitigating radiation damage is crucial for developing durable materials that can withstand the extreme conditions inside fusion reactors.
