We particularly focused our study on identifying the corrosion products formed at 30 °C carbon steel under aerobic and anaerobic conditions following their evolution with time due to enhanced microbial activity environmental geological conditions. The nature structural properties of were investigated by scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS), diffraction (XRD) confocal micro-Raman spectroscopy. Structural characterisation clearly showed formation iron...
Recent studies have shown that extensive chlorination of natural organic matter significantly affects chlorine (Cl) residence time in soils. This biogeochemical process must be considered when developing the conceptual models used as basis for safety assessments regarding potential health impacts 36-chlorine released from present and planned radioactive waste disposal facilities. In this study, we surveyed 51 French forested areas to determine variability speciation storage Concentrations...
In this study, we investigated the iron sulphides phase transitions resulting from steel corrosion under sulphate-reducing-bacteria conditions. Experiments were conducted at 30 °C 7 to 240 aging days. Culture batch experiments with coupons, clay and groundwater amended lactate simulate degradation anaerobic Solutions monitored by inductively-coupled plasma mass spectrometry ionic chromatography. The products scanning electron microscopy/energy dispersive X-ray spectroscopy, diffraction...
During the geological disposal of high‐level waste, nuclear glass is expected to be first hydrated in water vapor prior liquid alteration. In present work, we investigated hydration International simple ( ISG ) at 175°C and different relative humidities (60%, 80% 98%). The was by reaction analysis NRA Fourier transform infra‐red spectroscopy. chemical mineralogical compositions alteration products were studied using scanning electron microscopy/energy dispersive X ‐ray spectroscopy SEM ‐ EDS...
