A transition plate structure suitable for independent remote operation of the first wall of the divertor

Abstract

The invention discloses a transition plate structure suitable for independent remote operation of the first wall of the divertor. The transition plate structure is composed of a protective armor and a support plate welded, tungsten is used as the material of the protective armor, chrome-zirconium copper is used as the material of the support plate, and the transition plate structure It is connected with the support structure of the first wall by two connecting bolts. The inlet and outlet pipes of the first wall structure and the connecting bolts of the first wall structure of the divertor are located on the back of the transition plate. The multifunctional robot arm can enter the vacuum chamber from the upper and middle windows, remove the transition plate, and independently remove or install the first wall structure. The invention realizes the high-precision automatic and rapid installation or disassembly of the first wall structure of the divertor in a nuclear-related environment. The installation accuracy of the first wall structure of the divertor is improved, the installation steps are simplified, and the first wall structure only needs to be independently maintained through the middle window or the upper window, thereby reducing material waste. The invention of this structure has the advantages of saving money, saving time, 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 transition plate 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
