This article presents a methodology developed to assess and compare the technical, economic, safety, environmental performance of alternative radioactive waste management options across two technologies. Value assessment is form multi-criteria cost–benefit analysis, enabling holistic consideration wide range attributes (e.g., operational impact, disposability, financial aspects, implementability). For each attribute, several quantitative or qualitative metrics were included ensure that was...
Metal-organic frameworks (MOFs) show promise for the capture of greenhouse gases. To be used at a large scale in fixed-bed processes, their shaping under hierarchical structure is mandatory and remains major challenge, while keeping available high specific surface area. For that purpose, we propose herein an original method based on stabilization paraffin-in-water Pickering emulsion by fluorinated Zr MOF (UiO-66(F4)) with polyHIPEs (polymers from internal phase emulsions) strategy consisting...
The decontamination of wastewater is an important issue for the nuclear industry. removal Sr2+, one most problematic radioelements, requires hierarchical materials suitable fixed-bed processes. This article describes a patented emulsion-templating route synthesis Linde Type A (LTA) zeolite-geopolymer composites with multiscale porosity. By dispersing zeolite particles in emulsion oil-in-water containing precursors geopolymer, LTA zeolite–geopolymer can be obtained after curing and...
Handling nuclear metallic waste is a crucial issue for the industry, notably by using adapted decontamination processes. Colloidal gels can be applied spraying of large and plane surfaces, such as walls or floors. However, this implementation mode limits their use inaccessible complex geometries surfaces. For that purpose, magnetic have been formulated incorporating magnetite particles in pre-synthesized colloidal gel able to decontaminate stainless steel. Such thus attracted magnet,...
Strontium ions can be removed from wastewater in fixed-bed reactors by adsorption on hierarchical materials (different pore sizes and phases). A detailed understanding of the multiscale structure is therefore crucial to optimize their sorption properties. This article presents a multi-technique approach developed characterize relationship between microstructure range Linde-type (LTA) zeolite-geopolymer composites,. Two-dimensional scanning electron microscopy 3D X-ray tomography were used...
As a step toward synthesizing zeolite-based porous materials, this study demonstrates for the first time feasibility of stabilizing oil-in-water (O/W) high internal phase emulsions (HIPEs) using cationic surfactant (tetradecyltrimethylammonium bromide, TTAB) and "homemade" submicronic Linde type A zeolite particles. The particles are hydrophilic therefore do not attach to dodecane-water interfaces, but surface tension measurements electrochemical data show that their can be activated by...
