Influence of the Pb–Bi hydrodynamics on the corrosion of T91 martensitic steel and pure iron

Spectroscopic and microscopic study of the corrosion of iron–silicon steel by lead–bismuth eutectic (LBE) at elevated temperatures

“…Studies in flowing LBE include the work by Kondo et al [30], Zhang et al [31], Mueller et al [32], Aiello et al [33], Deloffre et al [34], Balbaud-Celerier and Terlain [35], and Ilincev et al [36]. The most relevant recent work is that of Ilincev et al [36], who studied some twenty varieties of steel, including Si-containing alloys.…”

High temperature liquid metal corrosion and its thermal hydraulic effects in spent fuel transmutation systems

“…The oxide-layer structure of steel in a liquid-lead alloy with oxygen control principally depends on steel composition, temperature, and hydraulic factors. For temperatures below 550℃, a 10-20 μ m external magnetite (Fe 3 O 4 ) layer and a compact internal spinel ((Fe,Cr) x O 4 ) layer of roughly equal thickness are generated on the pipe surface [13]. This duplex-layer can protect steels from corrosion，but it introduces more thermal resistant as well.…”

Corrosion issues in lead-cooled fast reactor (LFR) and accelerator driven systems (ADS)

“…22.14 between experimental points obtained from a corrosion loop in which cylindrical t91 samples are in rotation in the liquid Pb-Bi alloy [20] (in that case the mass transfer coefficient does not depend on the fluid velocity but on the angular velocity of the samples) and the expression obtained by the modelling performed above considering a mixed corrosion control (eq. 22.14 between experimental points obtained from a corrosion loop in which cylindrical t91 samples are in rotation in the liquid Pb-Bi alloy [20] (in that case the mass transfer coefficient does not depend on the fluid velocity but on the angular velocity of the samples) and the expression obtained by the modelling performed above considering a mixed corrosion control (eq.…”

“…One is a thermal-hydraulic based mass transfer code, MatliM [23], in which the corrosion process is described by tedmon's equation [19], taking into account the steel oxidation and then the oxide scale dissolution. it was shown that the corrosion rate of t91 is equal to that of iron [20]. this kind of model calculates the steel weight gain or loss (oxide scale thickness and material loss) as a function of the position in the loop.…”
