Rod ejection simulation on VVER 1000/320 core using PARCS/TRACE
The rod ejection (RE) is a design basis accident in accordance with NUREG-0800 and usually studied using point kinetics. In this thesis a 3D kinetic model is prepared and coupled with a thermal hydraulic system code for simulating this accident scenario for general VVER 1000 technology. This topic h...

| Resumo: | The rod ejection (RE) is a design basis accident in accordance with NUREG-0800 and usually studied using point kinetics. In this thesis a 3D kinetic model is prepared and coupled with a thermal hydraulic system code for simulating this accident scenario for general VVER 1000 technology. This topic has been defined by the Research Centre Rez of the Czech Republic as a part of a larger project concerning beyond design basis accident focused on the Station Black Out (SBO) and a Loss of Ultimate Heat Sink (LOUHS). Because of this, the simulation conditions will considered under SBO scenario. Initially the state of the art is discussed, followed by the general information on the major documentation needed for the analysis (10-CFR, NUREG-0800). This thesis shows the complete coupling methodology from a cross section generation to transient coupled calculation. |
