Control systems for reprocessing plants
Reactor and plant instrumentation and control: general architecture

The process characteristics to be controlled by the process control system are as follows:

• extreme diversity of the process :

  • heavy mechanics (unloading of castles, shearing, packaging of solid waste),

  • fine mechanics (PU O₂ conditioning),

  • various chemical operations (dissolution, liquid-liquid separation, purification, concentration, vitrification, treatment of liquid and gaseous effluents, bituming, etc.);

• specificity of the process equipment and in particular of the solution transfer devices due to the radioactive nature of these solutions;

• remote control of all equipment due to inaccessibility;

• maintenance of mechanical...
