Abstract

Abstract

In order to make full use of the post-irradiation fuel assembly, a fuel assembly repair process was proposed, and a repair system for post-irradiation fuel assembly was designed based on the dense and lightweight characteristics of the fuel assembly. Main parts were designed in detail and checked by seismic analysis using ANSYS. The results show that the stress and deformation of the main frame of the fuel assembly repair system meet the requirements. It is verified by the engineering test prototype that the system could dismantle and assemble the post-irradiation fuel assembly safely and reliably, and created conditions for the return of the fuel assembly.
