This article presented two-staged chemical precipitation for radioactive wastewater decontamination byusing chemical agents. The total amount of radioactive wastewater was 35 m3, and main radionuclideswere Cs-137, Cs-134, and Co-60. Initial radioactivity concentration of the liquid waste was 2264, 17, and 9Bq/L for Cs-137, Cs-134 and Co-60, respectively. Potassium ferrocyanide, nickel nitrate, and ferrum nitratewere selected as chemical agents at high pH levels 8e10 according to the laboratory jar tests. After theprocess, radioactivity was precipitated as sludge at the bottom of the tank and decontaminated cleanliquid was evaluated depending on discharge limits. By this precipitation method decontaminationfactors were determined as 66.5, 8.6, and 9 for Cs-137, Cs-134, and Co-60, respectively. By using thepotassium ferrocyanide, about 98% of the Cs-137 was removed at pH 9. At the bottom of the tank,radioactive sludge amount from both stages was totally 0.98 m3. It was transferred by sludge pumps tocementation unit for solidification. By chemical processing, 97.2% of volume reduction was achieved. Thepotassium ferrocyanide in two-staged precipitation method could be used successfully in large-scaleapplications for removal of Cs-137, Cs-134, and Co-60.
