Although a large amount of data (especially in abnormal conditions) is necessary to predict deterioration of nuclear power plant equipment, it is quite difficult to obtain it. For this reason, simulation is expected to be an effective approach to estimate conditions of equipment instead of data acquisition. In this study, we focused on and built a model for a motor operated valve, since the inspection cost is generally expensive due to the number of the valves used in a nuclear power plant. We analyzed the ...

Development of a Method for Predicting Deterioration of Plant Equipment -Simulating Deterioration Behavior of a Motor Operated Valve-

From a viewpoint of safe operation and the improvement in an operating ratio of equipment, Efficient maintenance engineering and inspection work is needed. Therefore, we developed a patrol system using 360-degree camera and self-localization technology. A 360-degree camera which can photo the image of all the directions was used for this system. It can record the spherical image of an inspection worker, and enables the inspection image of the direction to need. Moreover, early detection of change of an on-s...
