Dr. Noriaki Hirota is an accomplished materials scientist and Associate Deputy Director at the Japan Atomic Energy Agency, where he contributes extensively to research in structural and functional materials within the nuclear energy sector. He earned both his master’s and Ph.D. degrees in Materials Science from the Institute of Science Tokyo, with his doctoral research completed in 2025. With over 19 years of professional experience, Dr. Hirota has worked at the intersection of metallurgy, corrosion science, and mechanical engineering. During his tenure at Japan Steel Works, he developed high-performance turbine rotor materials for thermal power generation and advanced stainless steel forging processes. His subsequent work at the Japan Atomic Energy Agency has focused on developing corrosion-resistant materials for sulfuric acid decomposers in the Sulfur-Iodine hydrogen production process and improving stainless steels to mitigate stress corrosion cracking under extreme nuclear conditions. A member of The Atomic Energy Society of Japan (AESJ), he has authored several impactful publications in nuclear materials research. His work has significantly advanced the understanding of material durability and performance in harsh environments, earning him recognition for his technical innovation and leadership. Dr. Hirota remains committed to promoting sustainable energy solutions through advanced materials development.
