Abstract :
[en] During long-term storage of radioactive waste, steel containers will be corroded. This process leads to hydrogen production. A boundary value problem has been proposed to study the numerical modelling of the gas migration and its coupling with the mechanical strains
and stresses, under isothermal conditions. Biphasic fluid transfer model
(considering water, vapour, gaseous hydrogen and dissolved hydrogen) is defined. A 2D axisymmetric case with simplified geometry close to waste disposal in clay is modelled. Fluid transport problem is first resolved. Then, coupled mechanics and fluid transfers are modelled to determine the coupling effects.
