关于核电厂厂房混凝土氯离子危害与防治探究

Analysis and Evaluation for the Chlorine Ion Exceeding Standard in the Concrete of a Nuclear Power Plant

目前国内核电厂均处于滨海范围,大气环境会对核电厂厂房混凝土结构在全寿期带来不利影响。混凝土结构是核电厂重要物项和安全屏障,对核电厂厂房安全有着非常重要的作用,核电厂厂房在设计上有着比普通建构筑物更高的质量标准,混凝土的氯离子含量上更是严格控制。通过分析氯离子对混凝土结构的危害,结合核电厂老化数据的分析,对沿海核电厂在混凝土氯离子含量在施工阶段、运营阶段的预防和整治提出措施与建议。

At present,all domestic nuclear power plants are located at coastal areas,and the marine environment will bring adverse effects on the concrete structure of nuclear power plants during their whole life.The concrete structure is an important item and safety barrier of nuclear power plant,which has a very important role in the design of higher quality standards than ordinary structures,and the chloride ion content is strictly controlled.Based on the analysis of the damage of the chloride ion to the concrete structure and the analysis of the aging data of nuclear power plants,the prevention and treatment measures and suggestions for the chloride ion content in the concrete of coastal nuclear power plants from the construction and operation stage are put forward.
