Fuel pin behaviour under irradiation with high Pu content: Benchmark exercise. Comparison with experimental data.

This deliverable presents the results of the second phase of the benchmark. The deliverable first outlines the methodology adopted for this second phase, detailing the experimental data selected for the comparison and the improvements made by each code. The initial blind comparison for CAPRIX and TRABANT2/2 is presented in section 3.1, constituting the starting point of the approach. The final comparison for both pins, after improvements, is then presented in section 3.2. This final comparison details the discrepancies observed between codes and with experimental data, as well as the justification/explanation of these discrepancies for each of the calculation codes. Finally, section 4 summarizes the conclusions and main perspectives for future model development.
