Abstract
The modelling and the numerical simulation of corrosion take part in the general description of the nuclear waste repository. The derivation of models that are accurate in the long-time regime is a challenge, especially in this context. In this talk, Prof. Claire Chainais-Hillairet will start by recalling the Diffusion Poisson Coupled Model introduced by Bataillon et al. in 2010 and she will show how some minor corrections lead to a thermodynamically consistent model. This model consists in a drift-diffusion-Poisson system of equations on a moving domain. She will review the mathematical results she recently obtained with collaborators for this model and the main issues they are currently considering.

About the SFB 1313 Anneliese Niethammer Lecture Series
Anneliese Niethammer was the first female professor of the University of Stuttgart in 1947. The lecture series, dedicated to Anneliese Niethammer, is organised by the Collaborative Research Center (SFB) 1313 and takes place once a semester. Renowned international female researchers speak on relevant topics of current research in the research area of porous media.

Lecture Series
SFB 1313 organizes regular talks and project meetings with internal researchers, external partners and guests.
In 2021, SFB 1313 established the "Pretty Porous Science Lecture Series" (PPSL) with international invited guests.
Twice a year, SFB 1313 hosts the "Anneliese Niethammer Lecture Series". For this series, internationally renowned female scientists in the world of porous media are invited to present their current research. This event was founded by SFB 1313 to encourage young female scientists to pursue a career in science and serve as a platform for scientific exchange.
Workshops
SFB 1313 organizes workshops to promote the collaboration between SFB members and international scientists working on various fields of research and applications areas.
Status Seminars
The status seminars organized by SFB 1313 take place once a year. They serve as a platform to promote SFB 1313 and to bring together the internal members, external partners and other scientists working on the research area of porous media. These meetings shall give an opportunity to exchange ideas and transfer know-how.
