Abstract
Abstract According to this process, the working energy, in the form of at least two pulsed laser beams, is generated outside the contaminated zone (at 12A, 12B); this energy is conveyed by means of at least two optical fibres (18A, 18B) to a position near to the surface to be treated; at this position, the laser beams are combined (at 15) so as to produce at least one resultant laser beam (37); and this beam is sent onto the said surface, possibly via at least one return mirror. Application to the decontamination of the primary circuit in pressurised-water nuclear reactors. <IMAGE>
