Parameters and procedures of electro-kinetics decontamination experiments for radioactive concrete

This technology can allow to extract metallic nuclides deep inside of concrete without mechanical destruction of the structure. To maximize its advantages, the factors that affect the efficiency of decontamination should be properly taken into account. This study aims at developing optimized decontamination procedures through the investigation of test data from previous studies. In this paper, result of normalization by separation factor for each pH value and effects of contamination method were studied. Trend of normalized data were similar with original data because of the trend of separation factor by each pH values. Using 0.01 M acetic acid with chemical washing shows highest efficiency from normalized concentration of extracted contaminants. Because the samples contaminated after curing shows weak bonding strength, it should be considered for correct comparison
