Abstract
In a world of digitalization of power generation and fourth industry revolution, the demand for computational tools that can give support to the continuous improvements of industrial plants is increasingly high. In such a context, a computational code for thermal-hydraulic simulations is being developed to serve as a predicting tool for Angra 2 and 3 nuclear power plants. The objective is to build a model capable of providing process data – temperature, pressure and mass flow – under steady state and transient regimes by means of zero and one dimensional approaches, i.e., at very low computational cost. This paper describes the first stage of development of this numerical code, showing the mathematical modelling of each component that compose the power cycle. The validation process and the results for some special cases are also presented.
