METHOD FOR PROCESSING LIQUID RADIOACTIVE LAUNDRY WASTE FORMED AT NUCLEAR SITES

摘要

The method relates to the processing of liquid radioactive waste formed at different nuclear sites on deactivation of workforce overalls in specialist laundries. After washing, liquid waste from the washing and rinsing stages is collected and mixed, the mechanical impurities are removed from the liquid waste, and associating additives are introduced into said liquid waste the mixture formed is subjected to ultrafiltration, and the concentrate of impurities is sent to a conditioning stage, wherein, prior to the ultrafiltration permeate being returned to the laundry it is divided by reverse osmosis into a reverse osmosis concentrate, which is sent to the washing stage, and a reverse osmosis permeate, which is sent to the rinsing stage, which makes it possible to ensure a high degree of recycling of waste.
