  Abstract:  In order to improve the efficiency of a separation plant the whole process must be automatically controlled. A computerized control system is imposed by the high complexity of the isotopic separation process. The role of the data acquisition and control system is to keep automatically the separation process at an optimal level in all external conditions, eliminating the influence of the perturbing parameters. Regarding the separation plant from the point of view of the control engineering, the plant has one single useful output - the isotopic product. This output is characterized by a complex function, which involves qualitative (isotopic concentration) or/and quantitative (amount) properties of the product. There are two important inputs into the system: one is the amount of the substances and compounds, which supplies the plant, and the other is the electric power energy. Our first aim is to reduce to minimum the input/output ratio of the separation plant. On the other hand, applying this automatic control system we can reduce to minimum the operating personnel also. The hardware of the developed data acquisition and control system can be adapted to other separation plants, too, by the appropriate change of the sensors and the actuators. In this case the control software must be rewritten.
