A laser cleaning system for decontamination of radioactive contamination in nuclear power plants

Abstract

The invention relates to a laser cleaning system for removing nuclear power station radioactive contamination. The laser cleaning system comprises a laser generator, a laser transmitting device, a working monitoring system, a controlling system and a waste recycling system, the laser transmitting device is connected with a laser output port of the laser generator, the working monitoring system is arranged nearby target materials, the laser transmitting device comprises optical fibers, a mover, mechanical arms and an operating device, the optical fibers are connected with the laser output port of the laser generator and used for transmitting laser lights, the mover is used for moving laser output ports of the optical fibers onto the surfaces of radioactive contaminants, the operating device is arranged on the mechanical arms, the optical fibers are fixedly disposed in the mover, the laser output ports of the optical fibers are located at one end of the mover, one end of the mover is suspended in the air, the other end of the mover is installed on the mechanical arms, the operating device is used for controlling the mechanical arms and the mover to move, and the movement of the mover drives the laser output ports of the optical fibers to move.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a laser cleaning system used for decontamination of radioactive pollution in nuclear power plants. Background technique [0002] With the advent of a new round of domestic nuclear power plant unit construction peaks, the country has higher and higher requirements for nuclear power safety, nuclear pollution protection and treatment, emergency response, and environmental protection, and the corresponding technical requirements are becoming more and more urgent, especially those related to The demand for nuclear power safe radioactive pollution decontamination treatment technology will become more and more urgent. In the national medium and long-term scientific and technological development outline, among the key areas of priority support, the issue of nuclear power environmental protection and safety protection is mentioned, and it is pointed out that the promotio...

Problems solved by technology

These traditional decontamination methods have limited effects, and have certain restrictions on the use occasions and the shape and size of the components to be cleaned

These decontamination methods usually produce a large amount of waste water and waste liquid; there will be radioactive waste residues on the decontaminated objects; while cleaning, it will cause secondary pollution on the surface of components, which will bring great consequences to the subsequent treatment and disposal of radioactive waste. great difficulty

At the same time, there is a risk of corrosion to the substrate. In addition, these cleaning methods are mostly manual close-range operations, which pose a great health threat to the operators.
