the objectives of nuclear reactions for the improvement of nuclear data. These
results will contribute to improvement of the accuracy of numerical evaluations for
the concentration of activation products.
The methodology of sensitivity analyses stated in this study is efficient for
acquiring information about important impurity elements and nuclear reactions to
evaluate the activation product concentrations. This methodology can be applied to
the activations of ex-core structure materials if the appropriate one-group cross
sections are prepared with a corresponding neutron spectrum.
