DEVELOPMENT OF BUS DUCT INSPECTION ROBOT AT NUCLEAR POWER PLANT

摘要

Under the present situation, nuclear power plant has some places which are inspected with difficulty or not inspected due to narrowness or physical restriction, when carrying out periodical inspection. The subject of our research and development is to improve the accuracy of inspection and also to save labor (liberation from distress work of the worker) by applying a robot technology to the periodical inspection of the nuclear power plant. As a specific example, we report that developed robot can inspect inside the narrow space of Isolated Phase Bus ducts, which connect between a turbine generator and the main transformer.
