Results of the applicative benchmark between TRANSURANUS and GERMINAL on the ASTRID case study

This deliverable addresses one of the benchmark activities foreseen in Task 7.3 of INSPYRE, which focuses on the simulation of irradiation case studies representative of the ESNII reactor prototypes. The goal of this work is to assess the predictive design capabilities of fuel performance codes before and after the improvements brought about by the INSPYRE Project. The ASTRID case study, which was selected by the Task Force on fuel performance codes taking into account the needs expressed by the User Group, is a base irradiation for an axially heterogeneous fuel pin representative of the maximal loading condition in the ASTRID reactor. This case study was analysed by POLIMI using the TRANSURANUS fuel performance code and by CEA using the GERMINAL code.
