Research status of controlling hazardous substances in cutting and dismantling processes during the decommissioning of nuclear facilities
Cutting and dismantling are critical processes during the decommissioning of nuclear facilities.During the processes,harmful substances such as radioactive aerosols and smoke will be generated and released into the air,leading to severe environmental pollution and human health consequences.This article reviewed relevant literature on protection design for occupational hazards during cutting and dismantling processes reported by domestic and foreign scholars,providing a basis for controlling the harmful substances during the decommissioning of nuclear facilities.Atomization fixation technology and mobile local exhaust devices for controlling workplace harmful substances from the source and the end link have unique advantages and significant shortcomings.However,regarding whether secondary pollution will be generated,mobile local exhaust devices have more significant benefits due to their wide environmental adaptability and safety.Further in-depth research is needed on comprehensive control measures for harmful substances in cutting and dismantling processes during the decommissioning of nuclear facilities.
