PRA and margin assessment methodologies have been developed for sodium-cooled fast reactors against representative external hazards. This report describes the overview of last year (JPY2015) updates and the development of the sequence assessment methodology against a combination hazard of strong wind and rainfall.

For an evaluation of a combination hazard curve of forest fire and thunder, it is necessary to take into account not only the overlap occurrence frequency but also meteorological effect on a forest fire intensity. The logic tree of a forest fire hazard curve evaluation was utilized in this study for quantitative estimation of the hazard curve of the combination event of forest fire and thunder.

For sodium-cooled fast reactors, a margin assessment methodology against a combination hazard of strong wind and rainfall. In the combination hazard of strong wind and rainfall, the margin was defined as the grace period to heat transfer tube in the air cooler, of which fatigue failure is considered due to ingress of rain droplets into the air cooler duct following the air cooler roof failure of auxiliary cooling system due to wind-generated missiles.
