IODINE FILTER CONTROL STAND (SKIF) FOR CERTIFICATION CARBON SORBENT VENTILATION SYSTEMS OF NPP

The article provides information on the creation of the first iodine filter control stand (SKIF) in Ukraine, designed to determine the coefficient of purification of gaseous radioactive emissions from iodine and methyl iodide by sorbents used in ventilation systems at Ukrainian nuclear power plants. The possibility of using a stable isotope of iodine to determine the adsorption capacity of carbon sorbents is substantiated. The development, installation, start-up and adjustment of the pumping module and the measuring module were carried out when using air mixtures with methyl iodide based on the stable isotope of iodine 127I. The developed software allows you to use the stand in automatic mode. The manual for the operation of the SKIF stand was created and the method of determining the coefficient of purification of ventilated air from methyl iodide by carbon sorbents was certified within the framework of the enterprise standard.
