Еxperimental study of the efficiency of abrasive cleaning of nuclear power installations’s pipelines
https://doi.org/10.15518/isjaee.2024.01.214-224
Abstract
In the course of operation of NPP power units, radioactive deposits accumulate in the pipelines of various systems, which subsequently create high dose loads on the personnel performing work on the dismantling of these pipelines as part of the repair or decommissioning of NPP power units.
There are experimental results of abrasive cleaning of metal surfaces from accumulated contaminants which imitate radioactive deposits of steam-water circuits of nuclear power plants. The quality of cleaning surfaces with various abrasive compositions was compared with using a standardized visual method. Recommendations are given on further steps in the development of non-dismantling in-line abrasive decontamination methods.
