摘要

在核电站仪表与控制系统的设计过程中，必须考虑高可靠性和高安全性的要求。工程师还需要考虑冗余子系统(如反应堆保护、监控系统等)的增加会降低整个I&C系统的可靠性。本文提出了通过提高可靠性来提高核电站控制系统安全性的方法。该方法基于临界失效状态分裂的核电厂I&C系统状态转移模型。该方法的主要特点是可以使用一个模型计算可靠性和安全性指标。这种可能性允许研究维护策略和容错设计对系统安全性的影响。

Safety Estimation of Critical NPP I&C Systems via State Space Method

During design of Instrumentation and Control (I&C) Systems in Nuclear Power Plants (NPP) engineer should take into account requirements for high reliability and safety. Engineer also needs to consider that addition of redundant subsystems (such as reactor protection, monitoring systems etc.) decreases the reliability of the whole I&C system. In this article we present the method for solution of the problem of improving NPP I&C systems safety by improving their reliability. The method is based on the state-transition model of NPP I&C system with split critical failure state. The key feature of this method is the possibility to calculate indicators of reliability and safety using one model. This possibility allows investigating the influences of the maintenance strategies and fault-tolerance design on the system's safety.
