Fukui Smart Decommissioning Technology Demonstration Base is a base to support the growth of local companies about technology concerning the decommissioning of nuclear power plants. In decommissioning dismantling technology demonstration field, the facility that allows to virtually experience inside of the some areas of Fugen of JAEA with the actual scale and realistic sensation using Mixed Reality (MR) system is available. In order to carry out the decommissioning work safely and rationally, sufficient examination of work procedures in advance is necessary. One way for it is to use MR system that allows virtual experience of the site with actual size and realistic sensation, without entering the site. MR system enables visualization of the dose equivalent rate (mSv/h) at the site, examination of the dismantling procedure of the facility, examination of the installation place and size of the temporary equipment and confirmation of carry-in route and interference of the equipment necessary for dismantling work. It is possible to experience the site while moving through this space. One person can experience MR at a time and people other than the experiencing person can see the images viewed by the experiencing person as 2D images on the display. This MR system is supposed to be utilized for the purpose of developing human resources and improving technical skills in order to support companies in Fukui prefecture.
