Neutronic Analysis of the AP1000 Pressurized Water Reactor

The purpose of this paper is to present the neutronic analysis of the AP1000 reactor prepared by using OpenMC code. The principle of the code mentioned above is based on the Monte Carlo methods. Research included determining the neutron effective multiplication factor, analyzing of the evolution of fuel composition during the reactor’s operation, and verifying the effects of the boric acid in the coolant based on the parameters mentioned above. The final part of the paper is a summary which includes the conclusion of the analysis. The experiments confirmed the effectiveness of using OpenMC code for similar neutron-physics analyses. The yielded results overlap with experimental and literature data, indicating that a high level of consistency has been achieved.
