Computation analysis of the VVER-440 nuclear power reactor core
Máca, Pavel ; Šnajdárek, Ladislav (referee) ; Katovský, Karel (advisor)
This thesis is focused on effect of fuel assembly rotation on the reactor core optimization in VVER-440 reactor. In the first part of this thesis, a brief description and main parameters of VVER-440 reactor are introduced. Next chapter is focused on the Dukovany NPP reactor core design, where these reactors are in operation, together with evolution of used fuel assemblies and reactor core design optimization. The practical part of this thesis includes a comparison of reactor core design optimization with and without fuel assemblies‘ rotation. Furthermore, a so-called multiple rotation method is investigated, which could be more suitable compared to the currently used one.
