Device and method for adjusting center of laser decontamination light path of radioactive pipeline

Abstract

The invention discloses a device and a method for adjusting the center of a laser decontamination light path of a radioactive pipeline. The device comprises a laser decontamination workbench arranged on a lifting device, the pipeline arranged on a supporting frame and at least two center adjusting jigs, and the laser decontamination workbench comprises a decontamination laser device; and the lifting device enables the laser decontamination workbench to move in the first direction, the pipeline is arranged opposite to the decontamination laser device, laser generated by the decontamination laser device can pass through the pipeline, and the supporting frame can move in the second direction. According to the device and the method for adjusting the center of the laser decontamination light path of the radioactive pipeline, rapid and accurate center adjusting of a laser decontamination head can be achieved.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a radioactive pipeline laser decontamination optical path adjusting center device and method. Background technique [0002] With the rapid development of my country's nuclear power industry, more and more nuclear power units are being built. During the operation of nuclear power reactors, radionuclides will inevitably be produced and accumulated in the reactor core, and the radionuclides will be passed through by the main coolant. The primary loop system is brought to related systems, causing radioactive contamination of systems and equipment. Before the dismantling of the reactor, in order to reduce the intensity of the radiation field in the workplace, reduce the exposure dose of the operator, reduce the waste level, and reduce the amount of waste generated during the decommissioning process of the reactor, the circuit system needs to be cleaned and decontaminated. [0003] At p...

Problems solved by technology

[0004] In the process of radioactive laser decontamination of pipelines in nuclear facilities, it is usually necessary to place the laser decontamination head at the center of the pipeline. The same cleaning effect can be achieved; if the laser position deviates, the morphology of the inner surface of the pipe after cleaning will be quite different, and some areas cannot be cleaned. At the same time, the substrate in other areas However, it has already been damaged; once the pipeline is damaged, it will not only affect the subsequent production, but also may cause nuclear leakage during use, causing huge danger and loss
