Abstract


In this study, a support method of decommissioning work of NPPs using Augmented Reality has been proposed and a simple prototype system has been developed. Then, using the developed system, the concept of the proposed method was confirmed by a heuristic method. Three workers of Fugen NPP used the prototype system along with a scenario which dismantles an ion tower of a water purification facility, and then questionnaire and interview investigation was conducted. As the results, it was found that the superimposing display of colored CAD data in the cutting lines and dangerous parts was effective to be understood intuitively. And it was also found that the proposed method that records the cutting parts on the CAD data by operating them using a stylus pen was easy and effective to prevent from a mistake when recording.
