Reduction of Radioactive Waste from Remediation of Uranium-Contaminated Soil

다국어 초록 (Multilingual Abstract)

Great amounts of solid radioactive waste (second waste) and waste solution are generatedfrom the remediation of uranium-contaminated soil. To reduce these, we investigatedwashing with a less acidic solution and recycling the waste solution after removal of thedominant elements and uranium. Increasing the pH of the washing solution from 0.5 to 1.5would be beneficial in terms of economics. A high content of calcium in the waste solutionwas precipitated by adding sulfuric acid. The second waste can be significantly reduced byusing sorption and desorption techniques on ampholyte resin S-950 prior to the precipitationof uranium at pH 3.0.
