【 摘 要 】

Uncertainty analysis for corrosion depth of the spent nuclear fuel canister has been studied using differential analysis. It shows that the mean value presents a second-order linear increase while the variance demonstrates a first-order linear increase in 1000-year time history. By respectively incorporating correlation into pitting factor, uniform corrosion factor, oxygen concentration and chlorine concentration, it is found that the covariance of uniform corrosion factor and chlorine concentration has the highest contribution in the variance of total loss.
