FIELD: process engineering.
SUBSTANCE: set of invention relates to laser decontamination of shaped part surface and may be used for contamination of nuclear fuel rods. Decontamination is performed by affecting shaped part surface 3 sequentially by pulse laser beams with wavelength in UV range to remove shaped part surface layer particles for them to be sucked, then, off. Laser beams are distributed so that to irradiate simultaneously the edges of shaped part treated surface. Proposed method used device that comprises treatment chamber 1 with opening for shaped part 3 to allow part surface sections to be introduced into treatment zone 4, and appliances to deliver laser beams into treatment chamber. Treatment chamber comprises optical lines 11, 12 to allow laser beams therein and appliances to suck off removed particles.
EFFECT: laser decontamination of nuclear power plant units for their cleaning and dismantling.
