Automatic control system of the evaporator in the technology of spent nuclear fuel processing

The operation of the radiochemical plant is impossible without high-quality automatic control systems. In the technologies of spent nuclear fuel reprocessing, the method of continuous evaporation is often used for a solution conditioning. The effective continuous technological process will depend on the operation of the evaporation equipment. In this paper, the method of mathematic simulation is applied for the development and research of evaporator control system. Two systems were considered. Parameters of regulators were calculated and direct quality indicators were presented. As a result, an automatic control system with the low sensitivity of the system to the density variation was chosen.
