摘要
N取M判决系统是反应堆保护系统中的冗余设计,分析了判决系统拒动率、误动率两个量化指标,得到严格的数学公式并做了近似计算,解释了工程实际中N取M多为4取2或3取2经验值的基本原理。以非安全故障概率0.1、安全故障概率0.1为例详细比较不同取值的判决系统。依据设计参数给出三种N、M取值的算法,将工程参数选取与理论计算融合。
Abstract： M out of N judgment system is the redundancy design of the reactor protection system.Two quantitative indica- tors-the rate of refuse to operate and misoperation rate-are analyzed.A strict mathematical formula and the approximate calculation are stated. They were used in explaining why M out of N is 2 out of 4 or 2 out of 3 in engineering area usually. The difference of a se- ries of judgment system are discussed in detail when the non-security failure probability and the security failure probability are all 0.1. According to the design parameters, the values of N and M can be solved by using three algorithms. The engineering parameters selection and the theoretical calculation are integrated.
