摘　　要：针对自主研发的CF3燃料组件用包壳,基于锆合金腐蚀机理,通过分析堆内外腐蚀数据,开展了包壳腐蚀性能研究,建立了CF3燃料组件用包壳的腐蚀模型,并研究了模型的不确定性。验证结果表明最佳估算模型可以较好地描述CF3燃料组件用包壳的腐蚀性能,上界模型具有包络性。Based on the corrosion mechanism of zirconium alloy,the corrosion performance of cladding for CF3 fuel assembly was studied by analyzing the corrosion data inside and outside the reactor.The corrosion model of cladding for CF3 fuel assembly was established,and the uncertainty of the model was studied.The verification results show that the optimal estimation model can describe the corrosion performance of the cladding used for CF3 fuel assembly well,and the upper bound model has the envelope property.
