Results of TEM and SEM characterization of irradiated fuel before mechanical testing

The irradiated fuel samples tested in the mechanical set-up in task 1.1 will be characterized before the mechanical tests to measure their initial state. Images and measurements concern the dislocation densities (TEM), and the grain size and the orientations distribution (SEM).

Results from the boundary condition simulations and coupling of neutronics and thermal hydraulics to OFFBEAT

Neutronics and thermal hydraulics simulation results and associated boundary loading conditions for the fuel performance code OFFBEAT. Boundary loading conditions will be provided for representative irradiation conditions, as expected for the development and the validation in WP4 and WP5, with nominal irradiation including operating power transients, and design basis accidents such as LOCA and RIA. Detailed description of the methodology and associated open source codes.

Results of the verification activities

Verification report of the tools developed in WP4 with•benchmark performed between OFFBEAT and existing 3D codes (ALCYONE, BISON) on specific study cases for which those codes are validated with experimental data. •verification of MMM and SPH codes by comparing their results to analytical calculations in simple configurations•verification of the large-strain solver, the gas conductance model and other developments made in WP4 on OFFBEAT•verification of the models linked to the coupling computational scheme OFFBEAT/SCIANTIX.
