Research and Development of Margin Assessment Methodology of Decay Heat Removal Function against External Hazards is being carried out in the MEXT nuclear system research and development project from JFY 2012 to 2015. In JFY 2013, hazard and event sequence evaluation methodoloies were developed against snow, tornado and strong wind hazards. Volcanic ash diffusion simulation was also conducted to obtain a volcanic eruption duration. A numerical simulation for forest fire was performed to indicate that humiidity and wind speed were sensitive.

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.
