The Robots for Nuclear Power Plants
نویسندگان
چکیده
Nuclear energy becomes a major energy source worldwide even though the debating environmental and safety dispute. In order to cope with the issues related to the nuclear power plant, the uncertain human factors need to be minimized by automating the inspection and maintenance work done by human workers. The demands of robotic system in nuclear industry have been growing to ensure the safety of nuclear facilities, to detect early unusual condition of it through an inspection, to protect the human workers from irradiation, and to maintain it efficiently. NRL (Nuclear Robotics Laboratory) in KAERI has been developing robotic systems to inspect and maintain nuclear power plants in stead of human workers for over thirteen years. In order to carry out useful tasks, a nuclear robot generally requires the followings. First, the robot should be protected against radiation. Second, a mobile system is required to access to the work place. Third, a kind of manipulator is required to complete the tasks such as handling radioactive wastes and other contaminated objects, etc. Fourth, a sensing system such as cameras, ultrasonic sensors, temperature sensors, dosimetry equipments etc., are required for operators to observe the work place. Lastly, a control system to help the operators control the robots. The control system generally consists of a supervisory control part and remote control part. The supervisory control part consists of a man-machine interface such as 3D graphics and a joystick. The remote control part manages the robot so that it follow the operator's command.
