Characterization of lead-bismuth eutectic nanowires

Applied Physics A, 2005
In this work, lead-bismuth eutectic alloy nanowires were fabricated by a novel vacuum melting method and centrifugal process. An anodic aluminum oxide (AAO) template was used to produce an array of ordered, dense, and continuous Pb-Bi nanowires. Scanning electron microscopy and transmission electron microscopy investigations reveal that nanowires with ...

Expansion of solidified lead bismuth eutectic

Journal of Nuclear Materials, 2005
Abstract Lead bismuth eutectic (LBE) has been proposed both as spallation target and as coolant in a future accelerator driven system (ADS). Therefore this alloy should be fully characterised and its physical properties should be completely known before use.

Lead–bismuth eutectic technology for Hyperion reactor

Journal of Nuclear Materials, 2013
Abstract A small lead–bismuth eutectic-cooled reactor concept (referred to as the Hyperion reactor concept) is being studied at Los Alamos National Laboratory and Hyperion Power Generation. In this report, a critical assessment of the lead–bismuth eutectic technology for Hyperion reactor is presented based on currently available knowledge.

Corrosion of ODS steels in lead–bismuth eutectic

Journal of Nuclear Materials, 2008
Abstract Oxide dispersion strengthened (ODS) ferritic steels are advanced materials being developed for high temperature applications. Their properties (high temperature strength, creep resistance, corrosion/oxidation resistance) make them potentially usable for high temperature applications in liquid metal cooled systems like liquid lead–bismuth ...

The behavior of oxygen in liquid lead–bismuth eutectic

Journal of Nuclear Materials, 2013
By performing first principles calculations, we investigate the status and migration behavior of oxygen in liquid lead–bismuth eutectic (LBE). We find that oxygen prefers to bond with four Pb atoms, forming a tetrahedron-like oxide complex in LBE. Driven by temperature effect, each oxide complex diffuses, with undergoing a dynamical exchange between ...

Ni-rich precipitates in a lead bismuth eutectic loop

Journal of Nuclear Materials, 2010
Solidified LBE was sampled from the specimens, electro-magnetic pump, filter, drain valve and oxygen sensor at the JAEA Lead Bismuth Loop-1 (JLBL-1) where the structural material was made of SS316. The concentration of Ni, Fe and Cr in LBE were analyzed by the Inductive Coupled Plasma atomic emission spectrometer.

Natural circulation studies in a lead bismuth eutectic loop

Progress in Nuclear Energy, 2011
Lead Bismuth Eutectic (LBE) is increasingly getting more attraction as the coolant for advanced reactor systems. It is also the primary coolant of the Compact High Temperature Reactor (CHTR), being designed at BARC. A loop has been set up for thermal hydraulics, instrument development and material related studies relevant to CHTR.

Thermophysical properties of lead and lead–bismuth eutectic

Journal of Nuclear Materials, 2007
Abstract Among different heavy liquid metals, lead (Pb) and lead–bismuth eutectic (Pb–Bi) are considered at present as the potential candidates for the liquid spallation targets of neutron sources and accelerated driven systems and for the coolant of new generation fast reactors due to their very good neutron and thermal features.

Some physical data of the near eutectic liquid lead–bismuth

Journal of Nuclear Materials, 2008
Abstract Lead–bismuth alloys are under intense consideration as target material of spallation sources. The thermohydraulic design of such a target or related coolant systems requires a reliable data basis regarding the temperature dependent physical properties of such alloys.
