Evaluation of rare earth on layered silicates under subcritical conditions: Effect of the framework and interlayer space composition
(Elsevier, 2013)
Clay-based minerals are considered to be an important component in backfill barriers due to both their ability to seal and adsorb radioactive waste and to interact chemically with it under subcritical conditions. Herein, ...

Uranium immobilization by FEBEX bentonite and steel barriers in hydrothermal conditions
(Elsevier, 2015)
FEBEX clay is considered a reference material in engineered barriers for safe storage of nuclear waste and uranium is a minor component of high-level radioactive waste (HLRW) and a main component of the spent nuclear fuel ...

Competitive effect of the metallic canister and clay barrier on the sorption of Eu3+ under subcritical conditions
(Elsevier, 2014)
An in depth knowledge and understanding of high activity radionuclide (HLRW) immobilization processes on the materials composing the engineered barrier (clay and metallic canister) is required to ensure the safety and the ...

Quantification and comparison of the reaction properties of FEBEX and MX-80 clays with saponite: Europium immobilisers under subcritical conditions
(Elsevier, 2014)
The evaluation of the retention mechanisms in FEBEX and MX-80 bentonites, selected as reference materials to construct engineered barriers, carries major implications in the safe storage of immobilisation capacity through ...

Interaction of Eu-isotopes with saponite as a component of the engineered barrier
(Elsevier, 2011)
Bentonite is accepted as the best clay material in the engineered barrier of deep geological repositories (DGRs) for radioactive waste disposal. In recent years, the interactions between a wide range of rare-earth (REE) ...

Impact of hydrothermal treatment of FEBEX and MX80 bentonites in water, HNO3 and Lu(NO3)3 media: Implications for radioactive waste control
(Elsevier, 2015)
Engineered barriers of deep geological repositories (DGR) are commonly constructed with bentonite. FEBEX and MX80 bentonites have been selected by different countries as reference materials for the sealing of repositories; ...
