Lead-bismuth CANDLE - Japanese challenge for SVBR. Lead-bismuth fast neutron technologies in Russia are close to the demonstration. According to the declaration of the director of the energetic machine building department of the "Russian machines" company Vladimir Petrochenko, the first NPP with SVBR-100 reactor can be built in Obninsk in 2015.

In recent decades, civil fast reactor plants with heavy liquid metal coolants (HLMC) based on lead and lead-bismuth eutectic (LBE) alloys have been intensely developed.Both lead and lead-bismuth alloys have a number of advantages as compared with other coolants for reactor plants, including, first of all, small fast neutron capture cross sections, relatively low melting points and high boiling ...

The natural circulation ability and the system safety are obviously influenced by the two phase flow characteristics of liquid metal-inert gas. In this study, LENAC (LEad bismuth alloy NAtural Circulation capability) code has been developed to evaluate the natural circulation capability of lead-bismuth cooled ADS with gas-lift pump.

Lead-Cooled Fast Reactor (LFR) The Lead-cooled Fast Reactors (LFRs) feature a fast neutron spectrum, high temperature operation, and cooling by either molten lead or lead-bismuth eutectic (LBE), both of which support low-pressure operation, have very good thermodynamic properties, and are relatively inert with regard to interaction with air or water.

The liquid lead-bismuth cooled fast reactor is a direct circulation system, and the LBE does not change the phase state in the reactor. In addition, due to the simplification of the structure, the entire system is miniaturized, and the volume of the containment is correspondingly

Lead and Lead-bismuth Eutectic – Reactor Coolant. Lead, lead-bismuth eutectic, and other metals have also been proposed and occasionally used.The lead-cooled fast reactor is a nuclear reactor design that features a fast neutron spectrum and molten lead or lead-bismuth eutectic coolant. Lead-Bismuth Eutectic or LBE is a eutectic alloy of lead (44.5%) and bismuth (55.5%).

More efforts need to be carried out, especially on flow regime characterization, heat transfer coefficient and flow stability in natural circulation. For the purpose to study the basic mechanisms of HLM natural circulation as well as gas-lift pump, design activities of a lead-bismuth natural circulation loop were carried out in FDS team.
