Title:
COMPOSITE LASER DECONTAMINATION DEVICE AND METHOD FOR RADIOACTIVE DECONTAMINATION OF NUCLEAR POWER PLANT COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/196217
Kind Code:
A1
Abstract:
A composite laser decontamination device and method for radioactive decontamination of a nuclear power plant component. The composite laser decontamination device comprises at least two laser emission modules (51, 52), beam shaping modules (61, 62) having one-to-one correspondence to the laser emission modules (51, 52), and a laser shaping module (2); laser light emitted by the laser emission module (51, 52) enters the corresponding beam shaping module (61, 62) for beam shaping and then enters the laser shaping module (2) for laser shaping, and finally is output to the surface of a to-be-decontaminated base layer (1) of the nuclear power plant component; a pulse width of the laser light emitted by the laser emission module (51, 52) is different; the particular laser emission modules (51, 52) are determined to be enabled according to the surface attachment condition of the to-be-decontaminated base layer (1). According to the novel composite laser decontamination solution for a nuclear power plant, the particular laser emission modules (51, 52) are selected to be enabled according to the condition of an actual to-be-decontaminated surface.
