Abstract


Aiming at improvement of task performance and reduction of human error of water system isolation task in NPP periodic maintenance, a support system using state-of-art information technology, Augmented Reality (AR) and Radio Frequency Identification (RFID) has been proposed under the concept of off-site operation and maintenance support center, and a prototype system has been developed. The system has navigation function of which an indication is superimposed directly on the user¡Çs view to help to find the designated valves by AR. It also has valve confirmation function by scanning RFID tag attached on the valve. Using the prototype system, an evaluation experiment has been conducted in order to confirm its effectiveness and to reveal its problems. As the result of the experiment, it was found that the system improved efficiency and reliability of water system isolation task, and it was also found that the visibility of HMD and its troublesome feeling to wear were the problems of the system.
