Dismantling of the Reactor Pressure Vessel by Underwater Arc Saw Cutting
Arc saw cutting is a thermal cutting method to cut objects by arc heat due to an arc discharge caused by the application of a DC voltage between the object to be cut and a rotary saw blade. The melted object material is removed by the rotating blade. This method has a high cutting capability for thick metal components.
