摘要
为避免或减轻核电站数字化仪控系统软件共因故障,提出了一种半定量的多样性评估方法。该方法基于核电站运行经验,对各类多样性属性及其多样性准则分配有效性权重,开发了多样性评估工具,可用于核电站仪控系统的多样性评估工作,借助于该方法能及时发现设计的薄弱环节并改进。
A kind of semi- quantitative method of diversity assessment is proposed,in order to avoid or mitigate software common cause failure of digital IC systems in nuclear power plant. This method bases on nuclear station operation experiences,allocates effectiveness weight to each diversity attribute and its criterion,develops a diversity assessment tool. This method can be used to assess diversity of IC systems in nuclear power plant by which design vulnerabilities can be found earlier and make modification.
