Abstract

Forest fires are disasters caused by natural or human factors and have environmental as well as economic impacts such as loss of biodiversity, agricultural damage, and property damage. According to statistics, the number of forest fires and the area damaged are gradually increasing in Korea. In addition, there are cases where the units 1, 2, and 6 of the Hanul Nuclear Power Plant (NPP) have already been affected by forest fires. Korea has recently initiated research on forest fires under multi-unit probabilistic safety assessment (PSA) project. This paper deals with the impact on the loss of offsite power (LOOP), which is one of the NPP incidents and accidents affected by forest fires. To estimate the frequency of LOOP induced by forest fires, the PSA methodology for earthquakes, a representative external event, was referred.

估算森林火灾在异地电力损失事件中所占比例的方法

森林火灾是由自然或人为因素引起的灾害，会对环境和经济造成影响，如生物多样性丧失、农业损失和财产损失。据统计，韩国的森林火灾次数和受害面积都在逐渐增加。此外，哈努尔核电站（NPP）的 1 号、2 号和 6 号机组已经受到森林火灾的影响。韩国最近在多机组概率安全评估（PSA）项目下启动了森林火灾研究。本文讨论的是受森林火灾影响的核电站事件和事故之一--场外功率损失（LOOP）的影响。为了估算森林火灾诱发 LOOP 的频率，参考了具有代表性的外部事件--地震的 PSA 方法。
