The objective Provision Tree (OPT) methodology was applied for Generation-IV Sodium-cooled Fast Reactor system to analyses challenges and mechanisms for core damage prevention and containment function maintain and to clarify sets of design conditions. The OPT results were utilized to select the list of importance events of JSFR as an example.
