Fuel pin behaviour under irradiation with high Pu content: Benchmark exercise

In Task 2.2, three fuel pins with high plutonium content are modelled using multiple fuel performance codes: CAPRIX, TRABANT1 pin 1, TRABANT2 pin 2. The objective of Task 2.2 is to increase the codes’ validation domain through code-to-code comparison, comparison to experimental data and, if possible, development/improvements of models. Comparison of the codes results with the experimental data allows estimation of the validity of the codes and identification of the set of settings that produce results in the best agreement with experimental data. This deliverable presents the results of the blind benchmark phase. The deliverable outlines the methodology adopted for this benchmark exercise, detailing the codes used, the requested outputs and sensitivity studies performed.
