Case Study: Fortum improves safety and speeds nuclear decommissioning with NavVis reality capture

Reality capture workflows raise the bar for safety in nuclear decommissioning

Fortum, a major energy company, faced the immense challenge of decommissioning nuclear power plants, a process complicated by the need to minimize workers' exposure to radiation. To plan tasks safely and efficiently, they required highly accurate and up-to-date 3D models of complex plant environments, which were difficult and hazardous to capture using traditional laser scanning methods.

The solution was implemented by eSite, a service unit of Fortum, using the NavVis VLX mobile mapping system from vendor NavVis. This hands-free, wearable technology enabled rapid reality capture of the plants, drastically reducing the time personnel needed to spend in radioactive controlled areas. The results were significant: field work time was cut from many hours to approximately 45 minutes, reducing radiation exposure to workers by two-thirds. This provided field operators with precise 3D models and virtual reality simulations to practice and refine their procedures, leading to improved safety, shorter outages, and lower costs.
