Outline of Final Research Achievements

In the present study, uncertainty estimation of unmeasurable core neutronics parameters is studied, especially theoretical framework and implementation of numerical methods, and validity of the developed methods is confirmed through verifications. A new approach for the cross section adjustment and the bias factor method is developed based on the random sampling method in order to apply them to actual light water reactors. All goals of the present study are fulfilled and the above achievements are beyond the plan at the beginning of this study.
