Box body opening structure suitable for independent remote operation of first wall of divertor

Abstract

The invention discloses a box body opening structure suitable for independent remote operation of a first wall of a divertor, the divertor structure comprises a first wall structure, a box body, a boxbody supporting structure and a cooling water pipe, the first wall structure of the divertor is positioned by two positioning pins and fastened by two connecting screws, and six degrees of freedom ofthe first wall structure are restrained. A multifunctional mechanical arm enters the opening in the bottom of the divertor box body from a lower window of a vacuum chamber to cut or weld a connectingwater pipe, a connecting bolt is dismounted or mounted, and the connecting bolt is moved out of or into the first wall structure from a middle window or an upper window of the vacuum chamber througha hoisting mechanical arm. The first wall structure of the divertor can be quickly disassembled or assembled in the teleoperation process, the installation precision of the first wall structure of thedivertor is improved, the installation steps are simplified, the first wall structure can be independently maintained, and material waste is reduced. The box body opening structure has the advantagesof money saving, time saving, high efficiency and high precision.

Description

technical field [0001] The invention relates to the design field of divertors of nuclear fusion reactors, and mainly relates to a box body opening structure suitable for independent remote operation of the first wall of the divertor. Background technique [0002] Energy shortage and environmental pollution are two major problems facing mankind today. At present, fossil fuels are the main energy sources for human production and life. However, with the increase in global energy consumption and unscientific use, non-renewable energy sources such as fossil fuels will be increasingly exhausted, and will have a serious impact on the environment, causing serious pollution to the environment. This urgently requires people to develop hydrogen energy and nuclear energy. , wind energy, geothermal energy, solar energy and tidal energy and other new energy sources. The utilization and development of these energy sources can not only partially solve the crisis of fossil energy depletion,...

AI Technical Summary

Problems solved by technology

Therefore, for the overall remote operation maintenance scheme of the current nuclear fusion reactor divertor, its maintenance period is very long, but for the nuclear fusion reactor divertor components, most of the damage events occur on the first wall, and because the divertor will be damaged Radiation activation and contamination by tritium are harmful to humans, so that humans cannot directly contact them, so other divertor components that have been replaced with good functions cannot be reused, and the disposal of decommissioned components is also a major problem, so the use of The overall remote operation and maintenance of divertor components will inevitably cause unnecessary waste of resources
