Processing and Analysis of Reliability Data on Stator Cooling Pump

Based on actual failure data, reliability analysis of the nuclear power plant generator stator cooling water pump was given in this paper. The data were processed by statistical mathematics methods including empirical analysis, exponential and Weibull distribution fitting, and fitting results were verified. Finally, the comparison of reliability curves of exponential distribution and Weibull distribution of a component of generator stator cooling water pump was performed, and a practical equipment maintenance management was given.
