地震危险性与核电厂密闭可靠性的评价方法

Evaluation method for hermetic reliability of containment in nuclear power plant (NPP) considering seismic hazard

本文就考虑地震危险性时，核电厂安全壳的防泄露可靠性的评价方法进行了理论研究，探讨了地震模型问题中的参数确定的一些方面，给出了可靠性评价的总体思路、分析方法及具体步骤，确定了要考虑的不定参数及其描述，并进而利用概率断裂力学推导出可靠性计算的一般公式。

Some theoretical studies about evaluation method for hermetic reliability of NPP containment are done. Some problems in determination of parameters of seismic model are studied. The general idea, method and procedure of reliability evaluation are given, and the reliability evaluation formulas on the basis of probabilistic fracture mechanics considering seismic hazard are derived.
