“…Based on observed corrosion of steel in humid atmospheres at ambient temperature, the corrosion products are expected to be Fe(OH) 3 , and α-and γ-FeOOH (Booker, 1976;Furet et al, 1990;Kucera and Mattsson, 1987). Acceleration of corrosion by water vapor at ambient temperatures is well known (Evans, 1960;Fyfe, 1976) but the effect of water vapor on the types of corrosion products formed at relatively low elevated temperatures (<200°C) is not well documented.…”

Experiments to determine the effect of canister corrosion products on the transport of radionuclides will be undertaken using the Fe(II1) oxides goethite and hematite as proxies for the expected corrosion envelope that will form as a result of alteration of the corrosion allowance overpack prior to the breaching of the waste container. Samples of ESF invert concrete that have been crushed, or left intact but fractured, and that have been subjected to hydrothermal alteration will be used to determine the effect of cementitious materials on transport of radionuclides. A mixture of CaC03, SiO,, and aggregate will be used as a proxy for completely carbonated concrete.

“…Powder X-ray diffraction and infrared spectroscopy were used as complementary techniques. Mössbauer spectroscopy is especially suitable for studying steel corrosion due to its capability of identifying and quantifying the frequently found amorphous or noncrystalline phases of rust [19][20][21][22].…”

A low-carbon steel A-36 and two conventional weathering steels A-588 and COR-420 exposed at four atmospheric test stations located in (i) Tocumen, an urban site near the Pacific Ocean, (ii) Sherman-Open, (iii) Sherman-Coastal, and (iv) Sherman-Breakwater on the Caribbean coast of Panama. Kinetics of the short-term atmospheric corrosion process and the relationship with exposure time and environmental characteristics of each site were investigated. The atmospheric exposure conditions, particularly the time of wetness, deposition of chloride, and the washing effect of contaminants on the metal surface by rain are of upmost importance in determining the corrosion behaviour and composition of rust. The corrosion products were mainly identified using room temperature and low temperature (80 K) Mössbauer spectroscopy, FTIR, and X-ray powder diffraction. In all samples, γ-FeOOH and α-FeOOH were the main constituents. Maghemite (γ-Fe 2 O 3 ), magnetite (Fe 3 O 4 ), and Akaganeite (β-FeOOH) were also identified.
