Irradiation defects - WPMUIRD4

Objectif(s)

• Assess which simulation code/software should be used to investigate a given irradiation ageing phenomena ( multi scale approach)
• Compare simulation results with experimental measurement both carried out to quantify irradiation damage

Contenu(s)

• Fundamentals of DFT (Density Functional Theory) and application to irradiation damage (structure of condensed matter – Kohn Sham equations, waves function representation…)
• The displacement cascade (displacement threshold, PKA, influence of crystallinity)
• Experimental irradiations and realism with respect to irradiations in power plants (difficulties related to active materials, irradiation spectrum, manipulation…)
• Molecular Dynamics applied to displacement cascades
• Point defects (interstitials, vacancies in different crystallographic structures, complex impurity/interstitials and vacancies, point defects in ceramics)
• Electronic microscopy applied to the analysis of irradiated microstructures
A case study is given to the students

Statistical Physics, Quantum Physics, Crystallography and Basic Materials Science (phase diagrams, dislocations, diffusion laws).
