Special Issue Information
Dear Colleagues,
This Special Issue of Minerals will focus on the key processes and evolution of the near-field (NF) towards the assessment of radionuclide migration for high-level radioactive waste (HLW) disposal. The NF comprises the engineered barrier system (EBS) and the surrounding host rock in its immediate proximity that is significantly affected by repository construction and waste emplacement. Topics related to the following aspects, including laboratory experiments, in situ experiments, and modeling studies, will be considered for this Special Issue:
Early processes and the evolution of the EBS:
- The corrosion of the canister/container/overpack;
- THM processes and the evolution of the bentonite buffer (e.g., thermal processes, hydraulic/gas processes, mechanical processes, coupled processes and evolution);
- Geochemical processes and the evolution of the bentonite buffer (e.g., salt accumulation, cementation, buffer chemical evolution);
- Piping and/or erosion.
Long-term processes and the evolution of the NF:
- Interactions of different materials (e.g., iron–bentonite interactions, cement–bentonite interactions, or cement–rock interactions);
- Organic/microbe/colloid influence on radionuclide migration;
- Sorption and/or diffusion behavior in the EBS and the surrounding rock mass;
- Coupled modeling with radionuclide migration.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
