Research and Application of a Mobile Device Assisted Nuclear Power Plant On-Site Inspection Method

On-site inspection of nuclear power plants is an important operation and maintenance means to ensure the safety, reliability and economic of the operation of the units. Due to the complexity of the scene, generally, staff required to execute the inspection directly and cannot rely on automated equipment. The nuclear site exist a variety of risk factors, like other industrial sites, and also some other adverse environmental factors like radiation and other unavoidable ones, the overall personnel risk is proportional to the residence time and the complexity of the work. The use of mobile device combined with specially designed functions to assist the on-site inspections of nuclear power has been proposed in this paper which can greatly optimize the long time-consuming process such as positioning the inspection point, so as to reduce personnel risk and radiation dose. The mobile equipment can also assist the results of on-site multimedia recording, quick analysis, and help to carry out the preliminary issue cause determination. The on-site inspection assistance system developed based on this method has been successfully applied in many nuclear power plants and played an important role.
