Nuclear power plants (NPPs) transfer electricity using off-site power systems. Wildfires can disrupt these systems and cause a loss of off-site power, which can impact the operation of NPPs. In South Korea, wildfire incidents in 2000 and 2022 interrupted the operation of off-site power systems, affecting the NPPs. Furthermore, rising temperatures due to climate change are increasing the frequency of wildfires. Therefore, NPPs are expected to become more vulnerable to wildfires. Wildfire hazard maps are necessary for analyzing the impact of wildfires on NPPs. This paper proposes a methodology for generating a wildfire hazard map via Monte Carlo simulation. The proposed methodology was applied to the vicinity of the Hanul NPP, and a wildfire hazard map was generated
Abstract

Furthermore, rising temperatures due to climate change are increasing the frequency of wildfires. Therefore, NPPs are expected to become more vulnerable to wildfires. Wildfire hazard maps are necessary for analyzing the impact of wildfires on NPPs. This paper proposes a methodology for generating a wildfire hazard map via Monte Carlo simulation.
