Another great Twitter follow, @Saturnax1, added a couple of shots of the … WebMolten lead or lead-bismuth eutectic is the primary coolant because lead and bismuth have low neutron absorption and relatively low melting points. Melting and boiling points of lead and lead-bismuth eutectic mixture are: lead melting point – 327.5°C boiling point – 1749°C lead-bismuth – a eutectic mixture melting point – 123.5°C
Molten lead acts as a reflector for neutrons. Neutrons escaping the core of the reactor are to some extent directed back into the core, which allows a better neutron economy. This in turn enables more spacing between the fuel elements in the reactor, allowing better heat removal by the lead coolant.
