TREATMENT OF RADIOACTIVE LIQUID WASTE USING SUN HEAT
Keywords:Renewable Energy, Liquid Radioactive Waste, Evaporation, Distillation
This research aims to study the benefits of using the renewable energy in the field of treatment of liquid radioactive waste which is contaminated with a mixture of radionuclides such as Cesium Cs-137, Uranium U-238, Radium Ra-226,etc. which their evaporation degree is too high (more than 600C0 ) . The sun energy as example for renewable energy is used in the process of evaporation of liquid radioactive waste which formed from the decontamination by washing metallic pipes and washing a contaminated soil to convert liquid radioactive waste to more stable and less size radioactive waste in a form of sediment which treated later using cement and then to disposal. The effect of evaporation using sun energy on the human and environment is studied in the laboratory using chemical and radioactive measurement devices. A very good results had been gotten because no level of a radioactive contamination had appeared on the filter which had used in the evaporation process. An electric heater also had used for evaporation process and the results were the same which refers that radioactive nuclides weren't evaporate because of using low temperature. Liquid radioactive waste had distillated, the distillated liquid was measured, and it was clear from any contamination and this shows that there is no diffusion of radionuclides during evaporation process, and in this process the Decontamination Factor (DF) is very high.
