抄録	Nuclear data sensitivity analysis on light water reactor (LWR) nuclear fuel depletion with the modern evaluated nuclear data files were carried out. Sensitivity coefficients of the neutron multiplication factors k during nuclear fuel depletion to nuclear data were calculated using the reactor physics code system CBZ with the depletion perturbation theory. The single fuel pincell problems with UO2 and MOX fuels, the 3×3 multicell problems, and the PWR fuel assembly problems were prepared. The six modern evaluated nuclear data files were used, and differences in k from the reference JENDL-4.0 results were discussed using the sensitivity coefficients. In the results of the single pincell problems, the UO2 and MOX fuel problems show the different trend in the k∞ differences. Ragarding the 3×3 multicell problems, the existance of gadolinium changes the trend of the k∞ difference comparing with the single pincell model. The PWR assembly problems show the similar trend in the k∞ difference as the 3×3 multicell problems.
