Description

To identify the sensitive parameters in numerical simulation of radionuclide migration, a global sensitivity analysis model based on Latin hypercube sampling and Spearman partial rank correlation analysis methods is built. Sensitivities of key parameters at different periods of time are calculated. Spatial and temporal differences of parameter sensitivity are analyzed. The analysis results agree well with physical laws. This provides a basis for further work to calibrate the parameters and analyze the uncertainty. (authors)
