Description

A new method to improve the representation of the flux gradient in PWR assemblies during depletion calculations is presented herein. This original two-level scheme calculation consists in performing the depletion computation with two subsequent flux calculations based first on the Pij method with a general interface current formalism and then on the SN method. Several validations based on three different PWR configurations are presented: the absorption rate and the k obtained with the new scheme are compared with the values issued from some fine Pij calculations.
