Development of creep property equations of 316FR stainless steel and Mod.9Cr-1Mo steel for sodium-cooled fast reactor to achieve 60-year design life

316FR stainless steel and Mod.9Cr-1Mo steel are candidate structural materials for the present design of sodium-cooled fast reactor (SFR) in Japan. A number of research works have been performed in Japan to develop the SFR for practical use. Aiming at enhancing its economic competitiveness and reduc...
