LASER PROCESSING WITHIN CONTAMINATED ZONES OF A NUCLEAR PLANT, AND EQUIPMENT THEREFORE

摘要

COMPANY SAID: FRAMATOME Method of working with a laser in a contaminated area of a nuclear installation, and equipment for its implementation TECHNICAL CONTENT OF THE INVENTION According to this process, the working energy is generated, in the form of at least two pulsed laser beams, outside the contaminated area (in 12A, 12B); this energy is transported by means of at least two optical fibers (18A, 18B) to a location close to the surface to be treated; at this location, the laser beams are combined (at 15) so as to produce at least one resulting laser beam (37); and this beam is sent onto said surface, possibly via at least one deflection mirror. Application to the decontamination of the primary circuit of pressurized water nuclear reactors. Figure 1
