Lead-cooled fast reactor - Wikipedia

The lead-cooled fast reactor is a nuclear reactor design that features a fast neutron spectrum and molten lead or lead-bismuth eutectic coolant.Molten lead or lead-bismuth eutectic can be used as the primary coolant because lead and bismuth have low neutron absorption and relatively low melting points. Neutrons are slowed less by interaction with these heavy nuclei (thus not being neutron ...

What is a fast reactor?

Fast reactors split more atoms of U-238 than usual. Depending on the enrichment, our fuel's properties will be a mixture of these two plots. In order to sustain a chain reaction, the number of neutrons produced from fissions needs to be higher than the number of neutrons lost to capture (and a few other loss mechanisms like leakage out of the reactor).
