The Energy Systems Department qf the Technical University of Madrid has developed a model of Alniaraz NP Westinghouse three loops PWR design, for TRAC’E code in the framework of several projects sponsored by the Spanish Nuclear Regulatory Commission (‘cSN,) and the Electric Energy Industry qf Spain ( At present, a full power and a shutdown model are applied for sequences analysis. The model has been adjusted at several power rates and the steady state results show good agreement with plant data. In order to check the whole model a wide spectrum of transient simulations were performed, observing a good behavior For code and model validation, the simulation qf single RCP trip transient has been performed, comparing the results obtained with plant data.
