WATER LEVEL IN BOILING WATER REACTORS -MEASUREMENT, MODELLING, DIAGNOSTIC

摘要

The paper deals with the hydrostatic water level measurement in connection with the application of knowledge-based and model-based methods of signal processing using Fuzzy Set Theory, and under utilisation of internal gamma radiation as well as application of Artificial Neural Networks (ANN). The utilisation of Fuzzy-Set Theory and ANN's is explained. The principle of different measuring methods are described and placed underneath with applications, like Hybrid Observers and diverse measuring system for boiling water reactors.
