The effects of Calcigel bentonite naturally occurring microorganisms on corrosion of cast iron

Autor: Sushko, V., Matschiavelli, N., Wei, T., Stumpf, T., Cherkouk, A.

Publikováno v: EUROCORR 2022, 28.08.-1.09.2022, Berlin, Deutschland

In light of Germany's exploration of clay formations as potential hosts for deep geological repositories (DGR), and the most likely use of bentonite as a buffer material, copper or carbon steel/cast iron would be the most appropriate container materi

the microbial inventory of bentonite – how does it affect the long-term integrity of repository for high-level radioactive waste?

Autor: Sushko, V., Dressler, M., Wei, T.-S., Neubert, T., Kühn, L., Cherkouk, A., Matschiavelli, N.

Publikováno v: ISME Microbes, 14.-19.08.2022, Lausanne, Schweiz

The long-term and safe storage of high-level radioactive waste (HLW) in general, remains a challenge world-wide. The deep geological repository (DGR) is a concept of applying multi barriers to store the HLW and to ensure the long-term safety. Bentoni

Experimental Data: Endocytosis is a means of uranium(VI) uptake in tobacco (Nicotiana tabacum) BY-2 cells

Autor: John, W., Lückel, B., Matschiavelli, N., Hübner, R., Matschi, S., Hoehenwarter, W., Sachs, S.

Publikováno v: Publication date: 2022-01-01 Embargoed accessDOI: 10.14278/rodare.1046Versions: 10.14278/rodare.1047License: CC-BY-4.0

The interaction of tobacco (Nicotiana tabacum) BY-2 cells with uranyl(VI) nitrate in phosphate-deficient medium was investigated. The hypothesis was that endocytosis is a means of uranium uptake in these cells. Analysis was in the form of physiologic

Characterization of microbial communities in sedimentary clays used for deep geological repository

Autor: Wei, T.-S., Matschiavelli, N., Sushko, V., Schleicher, A. M. S., Cherkouk, A.

Publikováno v: 18th International Symposium on Microbial Ecology, 14.-19.08.2022, Lausanne, Switzerland

A deep geological repository (DGR) is a multi-barrier concept that has been a solution to store high-level nuclear waste (HLW). The natural Opalinus clay rocks are one of the candidates for entire DGR due to their unique geochemical features. However

The influence of the bentonite type on the corrosion of cast iron

Autor: Sushko, V., Dressler, M., Kluge, S., Matschiavelli, N., Schierz, A., Stumpf, T., Cherkouk, A.

Publikováno v: Tage der Standortauswahl, 11.-12.02.2021, Freiberg, Deutschland

1 Introduction Bentonite is considered as buffer and sealing material in a multi-barrier system for a deep geologic repositories (DGR) of nuclear waste and spent fuel [1]. Another part of the engineered barrier system is the containment of the radioa

Publikováno v: TransRet2020-Workshop on Processes Influencing Radionuclide Transport and Retention, 12.-13.10.2021, Karlsruhe, Germany

INTRODUCTION Bentonite is a potential barrier material in deep geological repositories (DGR) for nuclear waste and spent fuel [1] and it is critical to maintain its functionality for long periods of time. Bacteria, that can originate from the bentoni

Bentonite alteration in batch reactor experiments with and without fertilizing agents: implications for the disposal of radioactive waste

Autor: Podlech, C., Matschiavelli, N., Peltz, M., Kluge, S., Arnold, T., Cherkouk, A., Meleshyn, A., Grathoff, G., Warr, L. N.

Publikováno v: Minerals 11(2021), 932

Bentonite is currently proposed as a potential backfill material for sealing high-level-radioactive waste in underground repositories due to its low hydraulic conductivity, self-sealing ability and high adsorption capability. High saline pore waters,
