VR Decommissioning Simulation for Nuclear Facility Dismantling

The patent creates a virtual copy of the nuclear facility decommissioning environment using VR technology. The virtual space replicates the actual facility structure, equipment layouts, and decommissioning tasks, allowing operators to conduct experiments and collect data without physical exposure to radiation. This virtual replica enables multiple trial experiments to determine optimal operator numbers and task sequences while eliminating radiation exposure risks entirely.

The patent performs all necessary experiments and data collection in advance within the virtual environment before actual decommissioning operations begin. By conducting multiple trial runs, collecting measurement data, and analyzing results in the virtual space, the system determines optimal operator numbers, task progress orders, and operation routes beforehand. This preliminary experimentation eliminates the need for time-consuming on-site trials and provides reliable operational plans for actual decommissioning.

The patent implements a comprehensive feedback system that automatically monitors operator positions, task completion status, and progression through the decommissioning process. The system provides real-time feedback to operators through the VR interface, guiding them through correct task sequences and confirming completion. This automated feedback mechanism reduces coordination complexity by replacing manual supervision with intelligent system guidance that ensures all tasks are completed in the correct order.
