Testing FENDL-3/SLIB Neutron Cross-Section Data for IFMIF Neutron Source Applications

DESCRIPTION

This study evaluates the FENDL-3/SLIB neutron data library concerning its application to the IFMIF Neutron Source Facility. Utilizing the testing methodology, we performed neutronic calculations using the McDeLicious Monte Carlo code and a global 3D model of the IFMIF Test Cell. Our analysis covered neutron and gamma fluxes, nuclear heating, gas production, and displacement damage in High Flux Test Module (HFTM) irradiation rigs containing Eurofer specimens. Comparisons with standard IFMIF libraries and ACE data are discussed to validate the FENDL-3/SLIB results.
