Abstract

Abstract

In order to evaluate the radiation damage of fast reactor structural materials, a set of evaluation methods for radiation damage of fast reactor structural materials is proposed in this paper. According to the characteristics of the fast reactor energy spectrum, the irradiation scheme of the neutron flux detector is designed, the characteristics of the detector foil and the section of the reaction channel are analyzed, and seven kinds of fast neutron flux detectors are selected. At the same time, the iterative method is used to develop the spectrum analysis program in Labview platform. Based on the radiation experimental data of the Russian boron carbide module, the spectrum is analyzed, and combined with the calculation of the module cladding dpa of the Lindhard-Robinson model, and compared with the calculated value of SPECTER. The results show that the deviation between the dpa obtained by the experimental method and the calculated value of SPECTER is within 6%, which is in good agreement. In this paper, a complete set of radiation damage evaluation system for fast reactor structural materials is established, which is of great significance to the radiation damage monitoring of structural materials.
