Abstract For more than 10 years, the laser process has been studied for dismantling work; however, relatively few research works have addressed the effect of high-power fiber laser cutting for thick sections.. Since in the nuclear sector, a significant quantity of thick material is required to be cut, this study aims to improve the reliability of laser cutting for such work and indicates ..

There is a current interest in using laser cutting for nuclear decommissioning applications.. The benefits of using lasers for this application include the high speeds available, the tolerance of the process, the lightness of the cutting head, the lack of a reaction force with the part being cut, and the ease of automation of the laser cutting ..

The present work aims to analyze the potential of high-power fiber lasers for nuclear power plant decommissioning.. The main focus is to achieve higher performance and less waste than are found for Nd:YAG (which have already been studied) or CO 2 lasers.. 2.. Materials and methods..
IPG's Single-mode fiber lasers in either continuous or modulated mode are best suited for thin metal cutting (less than 1 mm) due to their ability to focus to the smallest of spot sizes.. The large power densities associated with the small spot and excellent beam quality enables cutting of intricate features at a high rate of speed..
Other laser-processing opportunities arise where the target location is hazardous or difficult to access, such as for nuclear decommissioning 17,39 or in the subsurface laser drilling of rocks for ..

A cutting study with a high-power ytterbium-doped fiber laser was conducted for the dismantling of nuclear facilities.. Stainless steel and carbon steel plates of various thicknesses were cut at a laser power of 6-kW.. Despite the use of a low output of 6-kW, the cutting was successful for both stainless steel and carbon steel plates of up to 100 mm in thickness.. In addition, the maximum cutting ..
