RESEARCH AND DEVELOPMENT OF RESOURCE-SAVING TECHNOLOGIES FOR RECYCLING OF TECHNOGENIC WASTE
Keywords:
decontamination, ultrasound, radioactivity, uranium, waste, metal, filter cloths, recyclingAbstract
The process of decommissioning uranium production equipment and technological tools leads to the formation and accumulation of metallic radioactive waste. The majority of this waste falls into the category of low-level radioactive waste and requires special conditions for storage. The use of ultrasonic treatment of TRW contributes to an increase in decontamination coefficients compared to traditional methods, while reducing the duration of the process. It has been established that the types of filter fabrics considered are subject to regeneration with the possibility of their subsequent use in industrial conditions. The effect of various solutions on the efficiency of the decontamination process of metal TROs has been studied. The possibility of single-stage cleaning of metal TROs in an ultrasonic field using HNO3 solution to obtain commercial metal with surface contamination of less than 1 alpha particle/cm2‧min at an acceptable level of less than 1.2 alpha particles/cm2‧min has been demonstrated.
