【 摘 要 】

In order to reduce low-level radioactive liquid waste, evaporation at atmospheric pressure was carried out for aqueous solutions containing a sub-volatile fission product in both nitric acid and sodium nitrate solutions. Decontamination factors of the distillates for Pd, Mo, Te, and Sb were the order of 10,000, and the percentages per square meters adhering to the condenser and the inside of the evaporator lid were between 0.001 and 0.0001.
