Most countries that generate nuclear power have developed radioactive waste management programmes during the last 50 years to emplace long-lived and/or high-level radioactive wastes in a deep underground repository in a suitably chosen host rock formation. The aim is to remove these wastes from the human environment. If a site is properly chosen, a repository system comprising both natural and engineered barriers would provide a high level of protection from the toxic effects of the waste.The 17 papers published in this Special Issue show that bentonites and clayrocks are an essential component of the multi-barrier system ensuring the long-term safety of the final disposal of nuclear waste. The efficiency of such engineered and natural clay barriers relies on their physical and chemical confinement properties, which should be preserved in the long-term.Research & information: generalbicsscBiology, life sciencesbicssccalcium bentonitegelswellingwater uptakeESEMEDXAsurface areaXRDradioactive waste disposalcement-clay interactionbentonitecementitious materialsalterationalkaline conditionsradioactive wastecement-clay interactionOPCLACalkaline leachatecement-clay interactiondiffusiondual porosityelectrostatic effectsreactive transport modellingnear fieldradioactive waste repositorylow-pH cementtechnical barrierÄspöABM-testsmectite alterationswelling pressurepermeabilityhydraulic gradientengineered barriersgeological repositoryselenium reductionsorptionOpalinus Clayin situbatch testssmectitecrystal structurewater in the smectite interlayermineralogical changesthermal treatmentBETswell indexliquid limitwater retention curvesironin situ experimentinterfacelayer chargemetal substitutionSEM-EDSmicrobial diversityorganic supplementsmagnesium bentonitethermal loadingmontmorillonite contentthermal analysis with evolved gas analysiscation exchange capacityspecific surface areasaturated hydraulic conductivitymicrobial survivabilityHLRWABM testSEM-EDXrepositoryhigh temperaturesordinary Portland cementmudstonesequential flow experimentreactive-transport modellinganion distributionCECexchangeable cationshydrationMiniSandwichsandwich sealing systemsolute transportwaste repositorieswater contentMilosinterlayersiron-bentonite interactionreactive transportnumerical modelbentonitessmectitespore water chemistrymineralogycation exchangeABM experimentlarge-scale testsResearch & information: generalBiology, life sciencesFernández Ana Maríaedt0Kaufhold StephanedtOlin MarkusedtZheng Lian-GeedtWersin PauledtWilson JamesedtFernández Ana MaríaothKaufhold StephanothOlin MarkusothZheng Lian-GeothWersin PaulothWilson JamesothBOOK9910580208503321Clay Mineral Transformations after Bentonite3037241UNINA
