Abstract

Various types of flame retardant cable are used in nuclear power plants. The cable insulation and sheath materials are generally categorized into two types: thermosetting ( TS ) and thermoplastic ( TP ) materials. Domestic cable fire damage criteria are set for each material type on the basis of the US guidelines, although they do not clearly define which type a TS / TP composite cable falls into. In this study, cable burning tests were conducted for TP and TS / TP composite cables used in domestic nuclear power plants to evaluate the validity of applying the US cable damage criteria to domestic cables. For varions cable damage scenarios, the tests measured the temperature / time dependence of insulation resistance between conductors and between cable and trays. The results of these tests justified the applicability of the US damage criteria. In addition, it was confirmed that the relationship be tween cable temperature and insulation resistance can be expressed by an Arrhenius plot. These find ings are expected to be utilized for the Safety Improvement Evaluation periodically conducted by nu clear facility operators.

考虑各类材料损伤标准的核设施电缆火灾损伤评估
各种类型的阻燃电缆用于核电站。电缆的绝缘和护套材料一般分为热固性(TS)和热塑性(TP)两种。国内的电缆防火标准是在美国指南的基础上为每种材料制定的,但没有明确规定TS / TP复合电缆属于哪种类型。本研究对国内核电站使用的TP和TS / TP复合电缆进行了电缆燃烧试验,以评价美国电缆损伤标准应用于国内电缆的有效性。对于各种电缆损坏场景,测试测量了导体之间和电缆与托盘之间绝缘电阻的温度/时间依赖性。这些试验的结果证明了美国损伤标准的适用性。此外,还证实了电缆温度与绝缘电阻之间的关系可以用阿伦尼乌斯图表示。这些发现预计将用于nu clear设施操作员定期进行的安全改进评估。
