摘要：
According to the work conditions of the component cooling pumps in nuclear-powered systems, the check valve in redundant pumps is taken as two redundant valves. Reliability chart was drawn and reliability analysis model was built up. Based on the example of equipment cooling pumps in nuclear-powered systems, the reliability of pumps in three conditions was separately calculated. Final results show that the reliability of two-component redundancy is much higher than that of single component, but the dependent failures between pumps and valves in redundancy decrease the reliability.
