“…The compositional and microstructural changes due to selective dissolution and intergranular corrosion can lead to material failures [33]. The dissolution rate depends on the liquid media, the ratio of the surface area of the solid metal to the volume of the liquid metal in a static solution, the flow rate in a dynamic solution, the surface conditions of the steel, the content of interstitial impurities such as oxygen and nitrogen in the liquid metal/alloy and the compositions of the solid materials [34].…”

“…The different solubility of the materials leads to selective dissolution and intergranular corrosion, which may cause the failure of structural materials eventually. The dissolution rate depends on the liquid media, the ratio of the surface area of the solid metal to the volume of the liquid metal in a static solution, the flow rate in a dynamic solution, the surface conditions of the steel, the content of interstitial impurities such as oxygen and nitrogen in the liquid metal/alloy and the compositions of the solid materials [5]. The temperature of the LBE loop affected the corrosion rate very much, because the solubility of the materials in LBE will increase as the temperature increases.…”

The corrosion of Liquid lead or lead-bismuth eutectic (LBE) on the structural steels is a serious problem for their application in fast reactors or accelerator-driven transmutation systems. This paper focuses on the modeling and experimental study on LBE corrosion in the spent fuel transmutation systems, as well as the effects of corrosion products on heat transfer and flow. By studying the corrosion and deposit of the oxidation products on the pipe wall, the empirical correlations of thermal resistance and fouling factor can be theoretically developed and experimentally verified. The comparison of fouling factors obtained with each oxygen level is presented, the relationship between fouling factors and oxygen concentrations is correlated, and the effects of oxidation on heat transfer are demonstrated qualitatively by wetting conditions of the samples.

“…1(a), the corrosive liquid metal corrodes the material uniformly along the surface of the solid phase structure material. 7,20) However, the liquid metal can penetrate into the solid material along the grain boundaries and some other crystal structural defects and causes a local corrosion. Figures 1(b)-1(d) illustrate the penetration of liquid metal along the specific crystallographic directions, along the grain boundaries, and along vacancies and pores, respectively.…”

The active oxygen control technique is a recently developed effective method for mitigating structural corrosions by forming a protective oxide film along the structural materials in corrosive lead bismuth eutectic (LBE) systems. The mechanisms of LBE corrosion and the oxidation of stainless steel in LBE environment have been analyzed. The active oxygen control technique is introduced and the oxidation experiment results with oxygen control are summarized. The buoyancy-enhanced oxygen transport, both laminar and turbulent, in the experimental LBE container has been numerically investigated using the finite volume method. The flux of oxygen at the gas-liquid and solid-liquid interfaces, the oxygen concentration in the bulk flow, and the rate of oxide layer formation are calculated. The time needed for the momentum and energy to reach the steady state and the time for the bulk concentration of oxygen to reach equilibrium are estimated. The rate of oxide layer formation on the steel surface under different thermal boundary conditions and diffusivities is also calculated. The numerical analysis provides a guideline for the design and setup of the apparatus in testing and calibrating low-concentration oxygen sensors and to study the oxidation of stainless steel containers for LBE.
