Title: The Innovations of Marc Perez
Introduction
Marc Perez is a notable inventor based in Levallois, France. He has made significant contributions to the field of materials science, particularly in the development of zirconium alloys for nuclear applications. With a total of 2 patents, his work has been instrumental in enhancing the performance and safety of nuclear reactor components.
Latest Patents
Marc Perez's latest patents include a method of making a sheet or strip of Zircaloy with good formability. This innovative method involves working an ingot, roughly shaping it into a billet, and then quenching it from the beta range. The process continues with hot rolling in the alpha range, followed by annealing and cold rolling to achieve thicknesses between 0.3 to 0.9 mm. The specific oxygen and carbon levels are carefully controlled to ensure a T texture is obtained for thicknesses of at least 0.8 mm. This method is particularly valuable for producing components for nuclear water reactors.
Another significant patent is for a fuel rod designed for a nuclear reactor, which features a sheath with an inner tubular layer and an outer surface layer made of different zirconium alloys. The surface layer, which constitutes 10 to 25% of the total thickness, includes a zirconium-base alloy with specific percentages of tin, iron, oxygen, and niobium or vanadium. The inner layer may consist of Zircaloy 4 or a zirconium-niobium alloy, enhancing the rod's resistance to corrosion and wear.
