NEUTRON-INDUCED DAMAGE SIMULATIONS: NOVEL NUCLEAR DATA FORMS AND METRICS FOR MATERIALS SCIENCE

摘要

Nuclear interactions can be the source of atomic displacement, embrittlement and postshort-term cascade annealing defects in irradiated structural materials. Such metrics arederived from, or can be correlated to, nuclear kinematic simulations of primary atomicenergy distributions spectra and the quantification of the numbers of secondary defectsproduced per primary as a function of the available recoils, residual and emitted, energiesand spectra. Recoils kinematics of neutral, residual, charged and also now includingmulti-particle emissions occurring at high MeV range energy are more rigorously treatedwhen based on modern, complete and enhanced nuclear data parsed in state of the artprocessing tools. Examples using the latest processing protocols and metrics appliedon recently released TENDL-2017, ENDF/B-VIII and JENDL-4 are given, while novelapproaches are proposed.
