Utilization of Red Mud for the Purification of Waste Waters from Nuclear Power Plants

Sorption of the radionuclides and heavy metals from low level liquid radioactive waste on the coagulant produced from bauxite waste (red mud and waste base) was presented. Research was conducted on composite annual samples of waste water collected in the Waste Monitor Tank (WMT) from Krško Nuclear Power Plant during each month. Activities of radionuclide in WMT were measured before and after purification using high purity germanium detector. Also, elemental concentrations in WMT before and after purification were measured by source excited energy dispersive X-ray fluorescence (EDXRF). It has been shown that activated red mud is an excellent purification agent for the removal of radionuclides present in low level liquid radioactive waste. For the radionuclides Mn-54, Ag-110, Sb-125 removal efficiency was 100%, Co-58 and Co-60 over 97% while Cs-134 and Cs-137 over 70%.
