Technical report on sodium technology in the field of material research; On the material corrosion and the mechanical strength in high temperature sodium

Yoshida, Eiichi

Corrosion research of the materials in high temperature sodium was done since 1960's in U.S., Europe, Russia and Japan for the development of sodium-cooled fast reactors, and the many excellent results were obtained. In Japan, various equipment was designed and manufactured to establish the material-testing technologies and to develop the sodium environmental effect methods. Up to present, the R&D examinations in sodium were performed using the equipment, and many experience and knowledge were obtained. The results were reflected to the experimental reactor "Joyo", the prototype nuclear reactor "Monju" and the R&D for commercial fast reactors. In this report, the sodium technology in the field of material research and the effect of sodium on material properties were reviewed based on author's experience and knowledge. Author hopes that the report is reflected to the future R&D and the technical succession for engineers.
