Power and burn-up distribution calculations for new units at Paks NPP using Monte Carlo methods
The new units at Paks NPP are going to be VVER-1200 type reactors. Such a high power reactors using new generation fuel assemblies and combined reactivity control methods, such as rod cluster control assembly, burnable absorber, fuel rods with axial profile, etc. In this study the radial power and burn-up distributions were studied using the SERPENT Monte Carlo code in case of basic geometrical arrangement.
