Problems solved by technology

In addition, after the fuel assembly has been dismantled many times, its 24 guide tubes are easily damaged, causing the screws to jam. The special structure of the guide tube makes it impossible to replace. Once the guide tube is damaged, the component simulation body will not be able to meet the component repair test and training. needs

Abstract

The invention relates to the technical field of nuclear power overhaul, and particularly discloses a fuel assembly simulation device with adjustable fuel rod clamping force. The overall boundary dimension and the main structure connection mode of the fuel assembly simulation device are consistent with those of a real fuel assembly; each clamping force adjusting mechanism comprises a fixed protrusion and a movable protrusion which are perpendicular to each other, and the movable protrusion is supported by a spring and can adjust the amount of compression applied to the movable protrusion; the clamping force adjusting mechanisms can be positioned and installed on a grillwork, fuel rods can be clamped and fixed through the fixed protrusions and the movable protrusions in the two clamping force adjusting mechanisms, and the clamping force on the fuel rods can be changed by adjusting the force applied to the movable protrusions. According to the fuel assembly simulation device with the adjustable fuel rod clamping force, an upper pipe base can be disassembled and assembled many times, and the requirements of long-term tests and training of fuel repair are met; and meanwhile, the clamping force on fuel rods can be adjusted, and simulation of the clamping condition of the real fuel rods is met.

Description

technical field [0001] The invention belongs to the technical field of nuclear power maintenance, and in particular relates to a fuel assembly simulation device with adjustable fuel rod clamping force. Background technique [0002] Fuel assembly repair Single rod replacement technology is an effective method to realize fuel assembly repair. In order to verify the effectiveness of the fuel repair operation tools and improve the operation skills of personnel, it is necessary to use the fuel assembly simulation body to carry out the simulation test of the operation process. The test process involves operations such as removing the screws of the upper pipe seat and pulling out a single rod. In order to be close to the real situation, the designed component simulation body needs to have a certain clamping force on the fuel rod. In addition, after the fuel assembly has been dismantled many times, its 24 guide tubes are easily damaged, causing the screws to jam. The special struct...
