Abstract

The present study deals with computational and analytical evaluation for the first approach of fuel loading, and presents the changes in neutron flux distribution of VVER-1000 reactor with each fuel loading type. The first approach proposed is based on dividing the core into axial cylindrical areas (equal number of batches), with each area having similar fuel (burn-up history). This paper includes a description of the core and fuel assembly lattice. The results allow us to determine the optimal first approach loading pattern, taking into account the maximum burn-up value, best power distribution and minimum vessel neutron fluence. The pressure vessel integrity analysis is carried out by comparing the vessel neutron fluence for each fuel loading scheme. Deterministic and probabilistic methods are employed in this study in order to achieve our goals.
