预应力钢绞线在核电站安全壳中的应用

Application of Pre-stressed Steel Strand to Containment of Nuclear Power Station

在介绍核电站安全壳的种类和结构的基础上,分析了CPR堆型和EPR堆型使用的预应力钢绞线的种类、数量和级别,以及核电用钢绞线的技术要求。指出为满足安全壳使用要求及安全要求,预应力钢绞线实物性能指标必须高于标准及规范要求。

On basis of introducing the type and structure of nuclear power station containment, the paperanalyzes the type, quantity and level of pre-stressed steel strand used for CPR type and EPR type reactorsand the technical requirement on steel strand for nuclear power application. It is also points out the indices ofphysical property of steel strand must be higher than that required by the standard and specification in orderto meet the application requirement and safety requirement of containment.
