Decontamination Method for Contaminated Soil in Decommissioning Nuclear Power Plant

摘要

The present invention relates to a method for decontamination of contaminated soil in a dismantled nuclear power plant, including a soil collection process, an input process, a high-pressure washing process, a physical fractionation process by particle size, a microbubble process, a first dehydration process, a filtration process, a coagulation sedimentation process, It includes the secondary dehydration process, capacitive desalination process, electric desalination process, discharge process, and solidification process, and it can maximize the decontamination efficiency and reduce the disposal cost to greatly reduce the disposal cost, and radioactive contamination and secondary It has the effect of minimizing the generation of waste and enabling safe and efficient treatment while minimizing the exposure of workers.
