On the temperature in a final disposal site for high-level radioactive waste
Autor: Artur Meleshyn, Ute Maurer-Rurack, Eva Hartwig-Thurat, Guido Bracke, Torben Weyand
Publikováno v: Safety of Nuclear Waste Disposal. 1:99-100
The Site Selection Act stipulates a precautionary temperature limit of 100 ∘C on the outer surface of the containers with high-level radioactive waste (HLRW) in the final disposal site. This precautionary temperature limit should be applied in prel

Which Processes could define Temperature Limits on the Outer Surface of a Container in a Disposal Facility ?
Autor: Ingo Kock, Torben Weyand, Artur Meleshyn, Eva Hartwig-Thurat, Jürgen Larue, Guido Bracke
When the recommencement of the search for and selection of a site for a disposal facility for HLRW in Germany was stipulated by the Site Selection Act (StandAG 2017) in 2017, a precautionary temperature limit of 100 °C on the outer surface of the co

Publikováno v: Los Alamos National Laboratory: Los Alamos National Laboratory Report LA-UR-16-28895, 2016
Nuclear Energy Agency: Nuclear Energy Agency (NEA) report, 2018
The evaluation of deep geological settings as sites for nuclear waste disposal is extensive and multidisciplinary, and among the many areas of study is the field of microbiology. The microbiology of granite, basalt, tuff, and clay formations in Europ

A Monte Carlo study of interlayer and surface structures of tetraphenylphosphonium-modified Na-montmorillonite
Autor: Florian Jeschke, Artur Meleshyn
Publikováno v: Geoderma. 169:33-40
Na-montmorillonite modified with tetraphenylphosphonium (TPP+) chloride has been shown to possess a high sorption capacity for iodide and a high thermal stability. We studied TPP+ arrangements in the interlayer space and on the external surface of Na

Adsorption of phenanthrene on Na-montmorillonite: A model study
Autor: Artur Meleshyn, Daniel Tunega
Publikováno v: Geoderma. 169:41-46
The role of clay minerals in the fate of polycyclic aromatic hydrocarbons (PAHs) in soil still remains an unresolved and controversial issue. Recent experimental studies report on PAH sorption capacity of clay minerals, which is either much smaller t

Microhydration of the Selenite Dianion: A Theoretical Study of Structures, Hydration Energies, and Electronic Stabilities of SeO32−(H2O)n (n = 0−6, 9) Clusters
Autor: Henryk Wicke, Artur Meleshyn
Publikováno v: The Journal of Physical Chemistry A. 114:8948-8960
In extension of the ongoing investigations of oxyanion-water clusters, we studied energetically low-lying configurations of hydrated selenite dianion (and in select cases, SeO(3)(-)) clusters using density functional theory (B3LYP, M05-2X, PBE0) and

Adsorption of Sr2+ and Ba2+ at the cleaved mica–water interface: Free energy profiles and interfacial structure
Autor: Artur Meleshyn
Publikováno v: Geochimica et Cosmochimica Acta. 74:1485-1497
Monte Carlo simulations show that the adsorption position of the Sr2+ or Ba2+ ion on the cleaved muscovite surface is determined by the radius of the ion’s first hydration shell, hydrogen bonding of the first shell water molecules with the basal ox

Potential of Mean Force for Ca2+ at the Cleaved Mica−Water Interface
Autor: Artur Meleshyn
Publikováno v: The Journal of Physical Chemistry C. 113:17604-17607
Monte Carlo simulations reveal that in the water coverage range of 0−28 H2O/Ca2+, Ca2+ is specifically adsorbed above tetrahedral substitutions of Si by Al at distances of 1.53−1.72 A from the clea...
