<ul><li>Engineers at the University of Surrey have developed a new technique to enhance the safety and durability of nuclear fusion power plants.</li><li>Through the PFIB-DIC imaging technique, researchers studied P91 steel welds in fusion reactors to identify stress-induced strength changes.</li><li>At high temperatures in fusion plants, the steel can become brittle and lose over 30% of its strength due to welding-induced stress.</li><li>This discovery will aid in improving materials testing, advancing reactor design, and accelerating the development of commercial fusion power plants.</li></ul>
