Implementation of a Novel ERANOS Procedure for the Adjoint Power Evaluation in Coupled Depletion Problems

Le résumé fourni par la source

The design of nuclear reactor cores heavily relies on the ability to evaluate burnup effects and the resulting changes in material composition at the isotopic level. When considering the design of liquid-metal fast reactors carried out using the ERANOS suite, a novel dedicated procedure to tackle depletion problems, based on the Generalized Perturbation Theory (GPT), was developed and imple- mented in the ERANOS suite. The preliminary results obtained by coupling the Boltzmann/Bateman fields, in both direct and adjoint domains, are presented and briefly discussed in this work, suggesting the possibility of their extension to more realistic applications and practical core design problems.
