Název v původním jazyce

Use of 2SPC depletion scheme in UWB1 nuclear fuel depletion code for the assessment of burnable absorber fuel design

Popis výsledku v původním jazyce

UWB1 depletion code is being developed as a fast computational tool for the study of burnable absorbers in University of West Bohemia in Pilsen, Czech Republic. Research of fuel depletion aims at development and introduction of advanced types of burnable absorbers in nuclear fuel. Burnable absorbers compensate for the initial excess reactivity and consequently allow for lower power peaking factors and longer fuel cycles with higher fuel enrichments. In order to achieve high precision within the UWB1 code, the Monte Carlo solver for lattice cell calculations is used to solve transport equation. Bateman equations are solved in 2sPC scheme - special depletion scheme that relies on nuclide-based predictor-corrector method in both transport and burnup part of fuel depletion. The paper describes the depletion calculations of CANDU, PWR and SFR nuclear fuel doped with rare earth oxides as burnable absorber. Uniform distribution of burnable absorber in the fuel is assumed. Based on performed depletion calculations, rare earth oxides are divided into two groups: suitable burnable absorbers and poisoning absorbers. Moreover, basic economic comparison is performed based on actual stock prices.
