Nickel solubility limit in liquid lead–bismuth eutectic

Journal of Nuclear Materials, 2010
Abstract In the framework of the Accelerator-Driven System (ADS), the Pb–Bi eutectic can be used as spallation target for neutron production. The Pb–Bi flow in contact with the ADS structural steels, T 91 (Fe–9Cr martensitic steel) and 316L (Fe–17Cr–10Ni austenitic steel), can dissolve the main steel components: iron, chromium and nickel.

Surface tension of lead–bismuth eutectic melts with lithium

High Temperature, 2016
The temperature and concentration dependences of the surface tension of lithium alloys (up to 33.1 at %) on the basis of a eutectic melt of Pb44.7Bi55.3 are measured in the range from the liquidus temperature to 700 K. The margin of error of the experiments was ~2%. Lithium has a low surface activity in the Pb44.7Bi55.3 eutectic melt, which agrees with

Atomistic simulation of liquid lead and lead–bismuth eutectic

Journal of Nuclear Materials, 2002
Abstract Lead and the Pb–Bi eutectic (Pb 55.9 at.%) have been modeled by a n -body potential derived from a second moment approximation of a tight binding Hamiltonian. The thermal behavior of the two systems in the liquid phase has been reproduced and relevant structural parameters have been evaluated and compared with experimental data.

Experimental Investigation of the Density of Molten Lead–Bismuth Eutectic

High Temperature, 2003
The density of molten Pb–Bi eutectic is measured by the pycnometer method in a temperature range of 410–726 K. The confidence of error of measurement, made up by the systematic and random components, does not exceed 0.1%. The experimental results are compared with the experimental data on the density of a liquid lead–bismuth alloy of eutectic ...

An atomistic insight into the corrosion of the oxide film in liquid lead–bismuth eutectic

Physical Chemistry Chemical Physics, 2014
When used as a protective scale, the Fe3O4 layer covering the stainless steel surface in accelerator driven subcritical systems (ADS) is corroded by liquid lead-bismuth eutectics (LBE). By performing theoretical calculations, we reveal that both Pb and Bi at the interface between the LBE and the Fe3O4 scale, favorably adsorb onto the Fe3O4 surfaces ...

Instrumentation of YSZ Oxygen Sensor Calibration in Liquid Lead-Bismuth Eutectic

2005 IEEE International Symposium on Circuits and Systems, 2005
Liquid lead-bismuth eutectic (LBE), a good candidate for the coolant in the subcritical transmutation blanket, is known to be very corrosive to the stainless steel that transports it. Such a corrosion problem can be prevented by producing and maintaining a protective oxide layer on the exposed surface of the stainless steel.

Critical temperature of the lead–bismuth eutectic (LBE) alloy

Journal of Nuclear Materials, 2005
Abstract Liquid metals such as Bi and Pb and Pb–Bi eutectic alloy are serious contenders for use as coolant in LMFBRs in lieu of sodium due to a number of attractive characteristics (high density, low moderation, low neutron absorption and activation, high boiling point and poor interaction with water and air, etc.).

Solution enthalpy of Po and Te in solid lead–bismuth eutectic

Journal of Nuclear Materials, 2014
Abstract It is examined to which extent first-principles calculations can be used to collect a priori information on the solution enthalpy and solubility of Po in solid lead–bismuth eutectic (LBE). Such information can be helpful to limit the number of complicated experiments that are required to measure these properties.

The Permeability and Solubility of Hydrogen in a Lead-Bismuth Melt of Eutectic Composition

High Temperature, 2004
The permeability of hydrogen through a lead-bismuth melt of eutectic composition is investigated, as well as the solubility of hydrogen in this melt in the ranges of temperature from 425 to 810°C and of hydrogen pressure from 1 to 3 kg/cm2. The experimental setup and procedure are described. The calculated value of the coefficient of hydrogen diffusion
