I participated in the EURAD WORKSHOP “Assessing the long-term evolution of engineered barrier systems of waste disposal systems” with a talk “Double-case canister lifetime evaluation with reactive-transport and chemo-mechanical models” prepared as overview of a national repository programme project, i.e. extra from the participation and results of the EURAD DONUT participation.
My previous personal knowledge and experience cover various fields of numerical modelling application in THM processes and radionuclide transport, relevant to the deep geological repository planning and safety assessment, but with minor interest to chemical and reactive transport modelling. The topic of the conference, i.e. the numerical modelling in relation to the chemical evolution of the repository barriers, was considered a convenient occasion to get deeper knowledge in this direction, making the progress more efficient than with individual literature study.
The experience and contacts will help me in the current and future work in the SURAO’s waste package lifetime project, both as a leader and as a numerical modeller in partnership with corrosion and bentonite mineralogy experts from other Czech institutes.
Additionally, presenting the SURAO’s concept of couble-case steel waste package to wider expert audience could bring valuable feedback not only to own numerical modelling work, but also to SURAO for future decisions in waste package development and use. In particular, it attracted attention of participants looking for alternative waste package concepts.
