Hydrogen retention in ITER's Diagnostic First Wall submitted to cyclic thermomechanical loadings

Résumé

A simplified ITER's Diagnostic First Wall is modelled in Abaqus Finite Element software to evaluate hydrogen retention after cyclic plasma exposure, and especially, the impact of mechanical fields. Using several User Subroutines, a strongly coupled chemothermo-mechanical problem is set and solved. Hydrogen field results with or without mechanical fields are compared, during the different loading phases, leading to the conclusion that, for this simplified problem, mechanical fields have no important impact on hydrogen retention.
