Since the data for the 1F building are installed in the system, it is possible toproject CAD and CG data as well as point cloud data that are measured
using a laser scanner.
Using these data, it is possible to discuss the plans for decommissioning withthis system and to practice the decommissioning. You can also use these datain your own laboratories (outside of NARREC).
The simulation can also be projected on a screen in cooperation with a robot
simulator. This enebles to verify the robot movement from 3D view andmultilateral viewpoints as well as to study and practice of the operationplans.
