| dc.description.abstract-translated | Nuclear data uncertainty propagation can be analyzed for various applications. Uncertainty of neutron multiplication factor during fuel depletion is the response quantity of interest for burnable absorber research. Three different fuel assembly (FA) designs were analyzed, FA without burnable absorber (BA), FA with gadolinium bearing rods in selected positions and finally, FA with uniform BA loading in all fuel pins. Newly developed BA materials would be introduced faster into reactor operation if they improve not only neutronics, but other safety or economics-related issues, i.e. accident tolerant fuel. Uniform BA loading is required for technical-economical analyses. VVER-440 fuel assembly depletion with non-uniform gadolinium and uniform erbium BA designs were analyzed with SCALE code package in order to show the effect of BA design on reactivity uncertainty. Nuclear data uncertainty analysis methods can be divided into first order perturbation theory based methods (TSUNAMI in SCALE) and Monte Carlo sampling methods (SAMPLER in SCALE). The first method has the advantage in fast calculation time due to the use of adjoint-based sensitivity approach, on the other hand, it is efficient only for a sufficiently small number of responses. The latter method requires performing large number of costly transport calculations, but can become quite competitive for complex models. | en |
