摘　　要：核电机组正常运行、事故分析及安全审评过程中需要重点关注蒸汽发生器水位的变化,蒸汽发生器水位不确定性分析是表征水位监测质量的重要手段。本文结合CPR1000核电机组蒸汽发生器水位测量原理,建立了系统完整的蒸汽发生器水位不确定性分析模型,并验证了CPR1000核电机组安全分析考虑的蒸汽发生器水位不确定性的合理性和保守性。The steam generator water level is one of the key parameter during normal operation,accident analysis and safety review of nuclear power plant.To demonstrate the quality of steam generator water level monitoring,uncertainty analysis is an important approach.This paper gives an all-round and systematic uncertainty analysis model of steam generator water level,based on the principle for CPR1000 steam generator water level measurement.Furthermore,the uncertainty of steam generator water level considered in safety analysis of CPR1000 nuclear power plant is proved to be rational and conservative.
