Abstract

The occurrence of a cable fire in a nuclear power plant can cause significant damage to the internal equipment and the defense system, and even reactor melt down in the worst case. In addition, toxic gases, released by burning cable jacket and insulation materials, can hinder human evacuation and fire fighting activities. Thus, this experimental study was conducted to investigate the toxicity of two non-class 1E cables which are applied to the nuclear power plants in Korea. Experiments were conducted for two kinds of cables according to the standard code of ISO 19702, and time series heat release rate, total heat release, and the concentration of toxic gases including CO, CO2, HCl, HCN, HBr, HF, NOx and SO2 were measured From the test results, the similar characteristics between heat release rate and CO2 emission and production of a small amount of halogenated compounds in emission gas caused by addition of fireproof components have been found. These results can be used as baseline data when assessing combustion characteristics and human toxicity of electric cables.

非1E类电缆燃烧特性的实验研究

核电站电缆火灾一旦发生，会对内部设备和防御系统造成重大损害，最严重时甚至会导致反应堆熔毁。此外，燃烧电缆护套和绝缘材料释放的有毒气体会阻碍人员疏散和灭火活动。因此，本实验研究是为了调查韩国核电站使用的两种非1E级电缆的毒性。根据ISO 19702的标准规范对两种电缆进行了实验，测量了时间序列放热率、总放热率以及CO、CO2、HCl、HCN、HBr、HF、NOx、SO2等有毒气体的浓度。从实验结果可以看出，由于添加防火成分，放热率与排放气体中CO2的排放和少量卤化化合物的产生具有相似的特征。这些结果可作为评估电缆燃烧特性和人体毒性的基线数据。
