Research and Application of Laser Decontamination Technology in Radioactive Pipelines
Laser decontamination technology has broad application prospects in deep decontamination of metal surface and radioactive hot spot decontamination due to its characteristics of small amount of secondary waste generation,easy access to narrow space work,high decontamination efficiency and easy automation.The influence of laser technology on pipeline performance was studied and applied to decontamination of radioactive pipeline in nuclear power plant.The decontamination effect of laser decontamination technology on internal dose of pipeline was demonstrated by measuring the contact dose rate before and after pipeline.On the basis of not damaging the pipeline,the contact dose rate of the internal surface of the pipeline is greatly reduced,with an average reduction of about 74％,which effectively reduces the pipeline dose and reduces the exposure dose of the staff,providing a theoretical basis for the subsequent cleaning and control of the radioactive pipeline.
