LFR
Lead-cooled Fast Reactor
Lead-cooled fast reactor (LFR) employs molten lead or lead-bismuth coolant for fast neutron breeding and high safety.
Coolant melts at 125-327°C, natural convection decay heat; ALFRED demo targets 120 MWe. Fuel metallic or nitride. Low pressure reduces vessel stress.
Why it matters now
LFRs attract EU funding for 2026 prototypes; corrosion-resistant materials advance for waste-burning SMRs.
