DEVELOPMENT OF THE KUOSHENG PLANT ANALYZER AND ITS ASSESSMENT WITH PLANT-DATA

We report on the development of the Kuosheng plant analyzer on an AD10 0 peripheral processor system for the Kuosheng nuclear power station a nd on benchmarking against plant data recorded during power tests. The Kuosheng plant analyzer was developed based on the Taiwan Power Compa ny's Chinshan plant analyzer with minor modifications. The modificatio ns include revision of models, preparation of an input deck, and regen eration of the plant-specific tables. The simulation speed of the Kuos heng plant analyzer is six times faster than real time. Also, the self -initialization algorithm and optimization module provide more conveni ent simulation. Three power test transients were simulated and benchma rked against plant data. Comparison results show good agreement with p lant data. The plant-specific component models were written as modular models, so that the Kuosheng plant analyzer can be easily modified fo r other boiling water reactor plants.
