A justification of laser decommissioning of nuclear reactors was experimentally proved at a nuclear reactor of KurskNuclear Power Plant. The main reason of laser beam application in this case is the marked decrease of radioactive radiationexposure of the service personnel. The use of a high power laser beam provided to realize laser cutting and weldingprocesses of a distance up to 35m between the laser and the workstation placed behind a contre - radiation shield. Byapplication oflaser cutting gas and dust contamination is tenfold decreased. Some results of decommissioning application ofa stationary laser workstation based upon a 5kw fast-transverse-flow discharge CW-C02 laser TL-5M installed of a nuclear reactor site are presented. A special high-beam-quality model of the laser was developed to satisfy the needs of decommissioning. Laser cutting process was applied to decommissioning of fuel channels (FC) of RBMK-l000 reactor,after their extraction from the reactor active zone during the procedure of channels replacement.Keywords: laser decommissioning, nuclear reactor, fuel channel, remote dismounting. |
