摘要：

The article is devoted to the determination of physiochemical forms of iodine radionuclides in the primary loop coolant of transportable nuclear power plants (TNPP) of pressurized water type with ammonia water chemistry. The main form of iodine radionuclides I-131-I-135 in the coolant is the iodide form. The content of iodate ions is 1-2% at an ammonia concentration of 18 to 79 mg/kg. The fraction of volatile organic and inorganic forms of iodine radionuclides passing into the gas phase from the coolant does not exceed 3.3 x 10(-2) and 2.5 x 10(-4)%, respectively.
