Abstract:
The automatic control system of uranium concentration in extract, raffinate and reextract of centrifugal extractor cascade is suggested. Control algorithms employ fuzzy logic and fuzzy neural networks. The suggested control system enjoys low sensitivity to plant parameters’ instability. It helps to reduce at least twice molybdenum content in final product and to increase process performance by 2–3%.
Keywords:affinage of uranium, centrifugal extractor, hybrid control system, fuzzy neural network.
