“…(43) can be used to predict the corrosion/precipitation rate profile in non-isothermal simple liquid metal loops. The equation has been extended to solutions that can be applied to multi-modular loops [106] and the transient corrosion/precipitation process [107]. Some observed corrosion phenomena (such as 'down-stream' effects) are naturally included.…”

“…The corrosion in lead-alloy systems is primarily due to the relatively high solubility of the base and major alloying components of steels, such as Fe, Ni, Cr, etc. 1 The process depends on many factors including the flow velocity, temperature and its profile, compositions of the liquid and solid materials. 2 Without some protective means, the selective dissolution of materials would destroy the containment structure rapidly.…”

The oxidation mechanism of steels in liquid-lead alloys (lead or lead-bismuth) was studied. Parametric dependencies of oxidation, including oxygen-concentration effects, oxidation-rate constant and corrosion-rate effects, are analyzed. An oxidation model is developed based on the assumptions that the chemical reactions are at equilibrium locally, and scale removal is due to mass-transfer corrosion. The model shows that outward-iron diffusion in the solid phase (oxide layer) controls the oxide growth and mass-transfer rate in the flowingboundary layer determines the corrosion-product transport in the liquid phase (liquid-lead alloy). The oxide thickness depends on both the parabolic oxidegrowth-rate constant and the mass-transfer-corrosion rate. For long-term operation, the outer layer of a duplex-oxide layer can be completely removed by flowing lead alloys and it is expected that a pure-chromium-oxide layer forms underneath the Fe-Cr spinel if iron is heavily depleted. The oxide thickness and steel weight change are very different from those of the pure parabolic law and they are classified into distinct and universal categories. The model is validated partially by application to interpreting the measured oxide behavior of several steels in a lead-bismuth eutectic-test loop.
