China's nuclear reactor dedicated robot technology made significant progress

In the "12th Five-Year Plan" period, 863 plans to deploy and implement a special robot technology and application project for nuclear reactors in the field of advanced manufacturing technology. In view of the urgent need of robotic technology for in-service inspection and maintenance of nuclear power stations and nuclear fuel replacement in China, Group Co., Ltd. takes the lead in developing the core technology and application of robotics in nuclear environment. After many years of research, the research group broke through a series of key technologies such as visual processing and precise positioning technology under nuclear radiation environment, anti-radiation reinforcement and antifouling and decontamination technologies, high irradiation and dynamic and static sealing under boric acid environment, Reactor refueling robot, the overall bolt stretching machine, multi-purpose underwater crawling robot six sets of nuclear reactor dedicated robot design and development of independent research and manufacturing.
At present, the reactor refueling robot and the multi-functional underwater crawler robot at the nuclear power station have completed the integrated manufacturing of the whole machine and the integrated system of the system. The robots of the reactor pressure vessel have completed the series of tests such as the electromagnetic compatibility, the irradiation performance of software and electrical components, Comprehensive functional verification, the whole reactor bolt tensile machine successfully carried out four full-function functional verification test, a steam generator side blocking operation robot, nuclear submarine micro-operation submarine has been Daya Bay Nuclear Power Base completed the prototype simulation environment and functional testing Verification, the performance indicators have reached the design requirements. Next, the six verified nuclear reactor robots will further demonstrate their applications in China's Daya Bay Nuclear Power Base, Guangdong Taishan EPR Third Generation Nuclear Power Station and Guangxi Fangchenggang Nuclear Power Station.
The successful development and application of special series of nuclear reactors will provide important technical support and operation equipment for the safety inspection and operation and maintenance of the core equipment of nuclear power plants in our country. To break the foreign monopoly and promote the independence and localization of the core equipment of nuclear power plants in our country, It is of great significance to upgrade and upgrade the production, operation and maintenance equipment and technologies to enhance the level of safety and security in the production of nuclear power stations in our country.
