Abstract EN
The effect of BWR fuel assembly 3D model on void reactivity coefficient (VRC) estimation is investigated.
VRC values were calculated for different BWR assembly models applying deterministic T-NEWT and Monte Carlo KENO-VI functional modules of SCALE 6.1 code package.
The difference between deterministic T-NEWT and Monte Carlo KENO-VI simulations is negligible (0.18 pcm/%).
The influence of the assumed more detailed coolant density profile was estimated as well.
VRC increases with the application of a larger number of coolant density values across fuel assembly height.
It was shown that the coolant density profile described by 6 values per height could be considered sufficient from prospect of VRC estimation, as a more detailed density profile has impact below 1% on total assembly void effects.
VRC values were decomposed to values for individual nodes and isotopes, since decomposition provides useful insights to describe the overall behaviour of VRC in detail.
