Laser cutting of thick steel plates and simulated steel components with a 30 kW fiber laser

Laser cutting of thick steel plates and simulated steel components were studied using a 30kW fiber laser for the application to the nuclear decommissioning. Successful cutting of carbon-steel and stainless-steel plates up to 300 mm thickness was demonstrated. Successful cutting of the thick steel components such as simulated reactor vessel walls, a large pipe, and a gate valve were also demonstrated. The results are informative for the application of laser cutting to the nuclear decommissioning
