Abstract
The model of multicomponent process of extraction in pulsating column is presented. Model analysis on adequacy to real apparatus was made. The received results have shown, that the presented model adequacy to the real nuclear fuel-reprocessing apparatus.
Highlights
In nuclear reactors there is no complete combustion of fuel, which is determined by either physical destruction of fuel, or premature deterioration of reactivity
The modeling results correspond to the experimental data in a wider range of parameters than the results presented in [7]
[7] In this paper we study single-loop and cascaded automated control systems (ACS), so it is necessary to choose such an output variable, the control of which could give the best characteristics of the output product
Summary
In nuclear reactors there is no complete combustion of fuel, which is determined by either physical destruction of fuel (fuel elements), or premature deterioration of reactivity. Nowadays spent nuclear fuel is processed using an extraction technology, which can provide separation of substances. Hardware design of this technology is based on counter current columns connected in cascade. In order to achieve high performance and high quality products with minimum production costs, the automated control systems (ACS) are used. The implementation of a good-quality automated control system of the extraction process will enhance its safety, improve technological and economic indicators of production as well as reduce the impact on the environment, due to decrease of toxic waste. In the development of automated control systems, it is advisable to use simulation models for the selection of the output variables, for the regulator settings and for the estimation of control quality. The aim of this work was to develop a universal model of the extraction process in a common extraction column with its further testing by ACS synthesis of extraction process in a real apparatus
