| Abstract: | Fuel assembly is one of the key equipment in nuclear power plant, and it is a high-risk operation for the maintenance of the fuel assemblies, especially when the replacement of the damaged rod of the spent fuel assemblies occurred.In this paper, the gripper structure of the replacement device of the spent fuel assemblies fuel rod was studied, and the optimal wall thickness of the gripper is obtained by structure statics analysis.After the strength of the gripper was verified through the finite element analysis, and then eventually followed by the trial production of the gripper.Through simulating the actual working condition of the gripper, the performance of the gripper was measured to ensure the gripper meets the requirement. |
