Abstract
In this work, reference data from the Angra 2 Final Safety Analysis Report (FSAR) have been used to perform the model and simulation of the Angra 2 Nuclear Power Plant (NPP). The system is a Pressurized Water Reactor (PWR) type with four coolant loops. The moderator is H2O which contains dissolved boric acid and which also acts as coolant through the core. The fuel assemblies are mechanically identical. They have a square cross section and are arranged in the reactor core in a pattern closely matching the circular shape of the surrounding cylindrical core barrel. Angra 2 was simulated using the thermal hydraulic RELAP5 code and the neutron kinetic PARCS code. The results have been compared with the available data and demonstrate that the developed model is capable to reproducing the behavior of the reactor in steady state operation.
