Title:
METHOD AND APPARATUS FOR DISMANTLING LARGE COMPONENTS OF NUCLEAR POWER PLANTS USING LASER CUTTING
Document Type and Number:
WIPO Patent Application WO/2021/201725
Kind Code:
A3
Abstract:
A method and apparatus for dismantling the nuclear power plant (NPP) components are provided. The method comprises: producing a focused laser beam (6) with a maximum output power of more than 20 kW by a laser module containing an ytterbium fiber laser (1), an optical fiber (2) and a cutting head (3). The method also comprises: laser cutting of the largest metal component (5) of NPP, related to reactor vessels, steam generators and heat exchangers; moving the cutting head by a robotic arm (11), removing the cut-out fragments (13) by auxiliary robotic arm (12) and cleaning of an air around the metal component from radioactive aerosols and volatile products of laser cutting using an anti-pollution equipment (9) configured to provide an enclosed space (10) around the metal component (5). The cutting is performed depending on the wall thickness in at least two different modes.
