Fuel debris retrieval is the indispensable task for decommissioning Fukushima Daiichi Nuclear Power Station (FDNPS). One of the significant barriers is the high radiation which deteriorates the operation efficiency. The radiation makes the robot sensors and the electronics get out of order easily. For the acceleration of decommissioning operation, it is required to develop the DX (Digital Transformation) platform to evaluate the sensor performance in the radiation environment. This research presents the approach exploiting a photorealistic game engine. The developed DX platform contributes to evaluate the sensor degradation and image processing algorithm inside the PCV (Primary Container Vessel) of FDNPS.
