With the development of national economy, science and technology, called upon by "generation" in the country, a great development of nuclear power, along with more and more into business shipments, overhaul units, nissan production, maintenance, testing of the necessity of using radiation resistant robot is more and more high, can largely improve the work efficiency, and reduce plant site staff received doses of radiation. Now, the plant's daily maintenance, test failure of operation and the development of robot technology has become a hot spot, robot technology has been popular in the nuclear power plant work. Plant work itself has complex structure, the characteristics of the running process cumbersome, moreover because of the particularity of their work, the plant will produce large amounts of radiation, in the process of work brings to the staff's life and health threats. The robot technology into the plant maintenance, strong radiation detection, treatment of waste, from a certain extent can improve the work efficiency, reduce work error cost savings, reduce the man-made accidents caused due to special reasons, to ensure the safety of employees. Developed in recent years the industry has been the research focus on job skills, complete functions, advanced technology, higher strength of the robot. In recent years, our country established on plant long-term development planning, the development of nuclear power plant in the cultivating place. The robot developed can meet the demand of nuclear power plant work has become the common wish of the nuclear industry's hope. This article mainly from the development history of nuclear power station robot technology, and then analysis the current plant robot technology development present situation and the development of the future.
