ROBOTIC LASER COMPLEX AND METHOD OF DISMANTLING METAL STRUCTURES OF NPP Russian patent published in 2021 - IPC G21C19/32 

FIELD: technological processes.

SUBSTANCE: invention relates to removal of large-size metal structures of nuclear power plant units decommissioned and subject to recycling. Robotic laser system includes environmental protection means (9) configured to arrange closed air space (10), in which cutting object (5) is placed and the cutting products output into the environment is prevented. Complex comprises at least one laser module (1) with output of radiation to transport optical fibre (2), to distal end of which is connected output optical module (3) with focusing lens (4), arranged on robotic manipulator (11) with three-coordinate movement. At least one auxiliary robot manipulator (12) is introduced to move fragments (13) of the cutting object. Preferably, laser cutting is carried out in at least two modes differing with cutting width. At that, by means of gas-dynamic channel (17) high-speed jet of air (20) is formed, which is directed to zone of laser cutting at an angle to axis of focused laser beam (6).

EFFECT: technical result is creation of high-efficiency environmentally safe technology of dismantling NPP power units.
