Corrosion behaviors of US steels in flowing lead–bismuth eutectic (LBE)
Journal of Nuclear Materials, 2005Abstract Corrosion tests of several US martensitic and austenitic steels were performed in a forced circulation lead–bismuth eutectic non-isothermal loop at the Institute of Physics and Power Engineering (IPPE), Russia. Tube and rod specimens of austenitic steels 316/316L, D-9, and martensitic steels HT-9, T-410 were inserted in the loop. Experiments

Abstract TiSiN coatings with different silicon content were deposited on 316 L steel by cathodic arc ion plating. After exposure, TiSiN coated samples presented good LBE corrosion resistance as compared with the bare steel. The main changes in TiSiN coatings were the oxidation of Ti and TiN and the PbBi penetration.

Molecular dynamics simulation of metallic impurity diffusion in liquid lead-bismuth eutectic (LBE)
Journal of Nuclear Materials, 2018Abstract Corrosion of stainless steels by lead-bismuth eutectic (LBE) is an important problem which depends, amongst other things, on the diffusion of the steel components inside this liquid alloy. Here we present the results of classical molecular dynamics simulations of the diffusion of Fe and Ni within LBE.

Oxidation of steel T91 in flowing lead–bismuth eutectic (LBE) at 550°C
Journal of Nuclear Materials, 2006This paper reports results of exposure experiments with martensitic steel T91 for 1200, 2998 and 5016 h in the COR-RIDA loop. Owing to initial problems with the enrichment of oxygen in the circulating LBE, the conditions with respect to the oxygen activity (expressed as the activity of lead oxide, a PbO ) varied significantly.

Abstract Liquid lead and lead-bismuth eutectic (LBE) are favored as primary side coolants for lead-cooled fast reactors due to their high heat carrying capacity, density, and boiling point. However, these liquids exhibit strong oxidation effects, leading to the formation of solid lead oxide particles. Additionally, they exert significant

An accurate knowledge on the production of radiotoxic polonium from proton irradiated lead-bismuth eutectic (LBE) targets is essential for the use of LBE in accelerator driven systems or in next generation RIB facilities. In this paper, six LBE targets were irradiated at different proton energies from 8.95 to 21.95MeV. For the first time quantification

Oxidation of Metals, 2013
For all LBE-cooled systems, the oxygen control technology must be applied for inhibiting corrosion by the liquid metal through formation of protective oxide layers on the structural material surface. The present study focuses on the stability of the protective layer in long-term operations subjected to LBE corrosion.
