Annotation: The paper considers the main tasks of automation and control of technologies of the extraction purification process of actinides, and also presents an approach to modeling an extraction column using the block-component circuit method (BCM) in the MARS (Modeling and Automatic Calculation of Systems) modeling environment and automation of the extraction process taking into account various effects. When modeling a column device to describe the extraction process, a diffusion model was taken as a basis, taking into account the conditions of mass transfer and hydrodynamics. The obtained results confirm the possibility of using the block-component chain method for the development of hardware chemical-technological systems and systems with the inclusion of integration models in the automat-ed control system (ACS) for optimization and improvement of the efficiency of technological processes.
