Homogeneity analysis of buffer barriers of high-level radioactive waste repositories by using the Gini coefficient under the density ratio model
The density ratio model based estimator of the Gini coefficient and hypothesis testing on this basis are introduced to nuclear safety field to measure the homogeneity of buffer barriers.The asymptotic theory involved in hypothesis testing is discussed.In addition to analysis by the Wald-type test,a valid Bootstrap process is designed to improve power.The above mentioned methods are applied to real data of the curing method called film covering storage method.The results suggest that film covering storage method can effectively protect the buffer barrier from becoming more inhomogeneous.
