Characterization of mechanical strain induced by lead-bismuth eutectic (LBE) freezing in stainless steel cup [PDF]
Heliyon, 2020 Lead-bismuth eutectic (LBE) is a candidate liquid metal coolant for a fast reactor, especially accelerator driven system (ADS). Freeze sealed valve is a candidate design to be possible to add passive safety to the reactor. On the other hand, since LBE is

Experimental Study on Diffusion of Ni in Lead-bismuth Eutectic (LBE)
Energy Procedia, 2015 AbstractLead bismuth eutectic (LBE) is considered as a spallation target and a coolant for the future accelerator driven system (ADS) or fast breeder reactor (FBR), due to its excellent properties. However, LBE is corrosive to structural materials like austenitic stainless steels if they are exposed to LBE directly.

Procedia Engineering, 2016 AbstractMolecular dynamics method was applied to simulate the physical properties of liquid metals: lead, bismuth and a binary alloy-- lead-bismuth eutectic (LBE). The embedded atom method (EAM), an empirical model rooted in density-functional theory, was used to represent the many-body interaction within the liquid metals.

Nuclear Engineering and TechnologyFlow-induced vibration (FIV) is a common cause of equipment breakdown and is prevalent in engineering applications. Lead-bismuth eutectic (LBE) fluid has emerged as a new heat exchange medium in recent years. Understanding the FIV characteristics of rod bundles in liquid LBE is crucial for engineering issues such as the design of rod bundle ...

Thermochemistry of Polonium Evaporation from LBE
Thermo, 2021 Polonium is formed in relatively large quantities in lead-bismuth eutectic (LBE) cooled nuclear systems. Because of its radiotoxicity and volatility, a good understanding of the chemical equilibria governing polonium release from LBE is required. In this
