PRA的特点是:它是一种逻辑化和系统化的研究工具;它可以提供电厂的整体模式;它能给出可能发生堆芯损伤的最重要途径的最可用信息;它可对同一类问题或包含类似系统的问题加以排队和分析。而PRA的弱点是:固有的模型不完善;缺乏高质量数据库;双态逻辑束缚了部件或状态的定义;对系统、堆芯以及安全壳缺乏事故条件响应
PRA is characterized by: it is a logical and systematic research tool; it can provide the overall model of the power plant; it gives the most useful information on the most important ways in which core damage may occur; Or contain similar system problems to be queued and analyzed. PRA’s weaknesses are: inherent model imperfections; lack of high-quality databases; the definition of components or states by dual-state logic; and the absence of accidental conditions on the system, core, and containment
