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 from the fuel reference state calculations

Fuel reference state (i.e. chemical-physical material changes and the associated mechanical loading) evolution will be provided during representative loading condition under design basis accidents such as LOCA and RIA, as expected for the development and the validation in WP4 and WP5. Fuel data will be derived from validated 1.5D fuel performance codes.

Second Newsletter

Mechanical laws for cladding, including based on results of INCA project for coated cladding

Mechanical models and material parameters describing thermo-elasticity, creep and rupture for zirconium alloys under irradiation, including coating behaviour for EATF claddings. Description of the state of the art data base and material parameter identification for Zirconium alloy. Reverse engineering methodology used for the coating mechanical law

Numerical and mathematical approaches for computation time reduction

Bibliographic report with a detailed analysis and description of computation time reduction methods based on machine learning models (MLM) with:•the Proper Orthogonal Decomposition (POD)•the Non-uniform Transformation Field Analysis (NTFA)•the Support Vector Machine approach (SVM)
