ABSTRACT
VALIDATION OF NUCLEAR DATA FOR STRUCTURAL MATERIALS BY INTEGRAL METHODS. Nuclear data for structural materials is needed to ensure the operation safety of nuclear reactors. To avoid some accident of nuclear reactors, so validation of nuclear data is needed continuously. Some methods have developed to increase accuracy of nuclear data, like differential and integral methods. In this paper, we will describe the integral method by energy independent adjoint flux that based only at measurement of reactivity absorption. Different structural material such as Fe, Ni, Mn, Cu and Cr, their nuclear data have been evaluated.
