数字化反应堆保护系统自监督设计
|
摘要
数字化反应堆保护系统运行期间需要通过各种监督测试确认其可用性和安全性,自监督是一种重要的监督测试类型,从功能安全角度分析自监督也有其必要性。依据相关标准的安全原则要求,提出了一种数字化反应堆保护系统的自监督设计方案,包括自监督的对象、实现方法、发现异常的处理、结果信息显示等方面的内容,为相关产品设计提供了参考。
Digital reactor protection system should maintain capability of safety and availability during operation which can be validated by surveillance testing,and self-supervision is an important type of surveillance testing. Self-supervision is also necessary from view of functional safety. Based on safety criteria from related standards,one self-supervision design scheme of digital reactor protection system has been proposed which includes its objects,implementation methods,anomalies disposal,results display,and can be referenced in future related product design.
