[3P06] Study on External Hazard Conditions Applied to Conceptual Design of a Next-Generation Sodium-Cooled Fast Reactor

＊Hidemasa Yamano¹, Nobuchika Kawasaki¹, Shigenobu Kubo¹ (1.Japan Atomic Energy Agency)

Keywords:Sodium-cooled fast reactor, Safety design requirement, External hazard

Tentative external hazard conditions assumed for a next-generation SFR design in 2011 were not reasonable because of an envelope range covering severe conditions. This report proposed a reasonable definition method of external hazard conditions and defined specific design basis and design extension conditions against various external hazards.
