FENDL-3/SLIB FENDL-3/SLIB Testing - ConclusionsTesting - Conclusions

It works for IFMIF applications !

Good results for n- and -flux spectra

Nuclear heating in general good

Gas production dataProblems in d and t production data (iron, NaK)

Reduced damage production in Eurofer (20%)

Still many "matching problems" at 20 MeV

Further applications tests required for Tritium release & creep/fatigue Test Modules, and shielding calculations
