Sodium-Cooled Fast Reactors as a Generation IV Nuclear Reactor

A Sodium-cooled Fast Reactor (SFR) is a type of nuclear reactor that utilizes molten sodium metal as the reactor coolant as it allows for a high power density with a low coolant volume. [3] An SFR can achieve a core power density of around 300 MW/m 3 compared with Pressurized Water Reactors (PWR) that achieve 100 MW/m 3 . [4]

6.1. Overview and motivation for lead-cooled fast reactor systems. Lead-cooled fast reactors (LFRs) are fast spectrum reactors cooled by molten lead (or lead-based alloys) operating at high temperature and at near atmospheric pressure, conditions enabled because of the very high boiling point of the coolant (up to 1743°C) and its low vapor pressure.
