摘要
核电厂DCS系统是整个电厂安全运行控制的神经中枢,由安全级系统和非安全级系统两大部分组成。由于安全级系统用于核反应堆的控制,因此对其可靠性提出了非常严苛的要求。为了确保核电厂DCS安全级系统的可靠性满足设计要求,对其硬件设备采用实验的方法进行可靠性试验,对其软件设计采用IV&V的方法进行可靠性验证。
Digital Control System of nuclear power plant is the nerve center for safety operation,which included safety and non-safetytwo systems.Because safety system was used to control nuclear reactor,the request of reliability for it is very high.In order to ensure thereliability of safety system satisfy design request,adopt experiment method to validate hardware reliability,and IV&V method to validatesoftware reliability.
