SUPERSTAR: an improved natural circulation, lead-cooled, small modular fast reactor for international deployment

Abstract: An improved 120 MWe (300 MWt) Secure Transportable Autonomous Reactor (STAR) lead-cooled, pool-type, small modular fast reactor named the Sustainable Proliferation-resistance Enhanced Refined Secure Transportable Autonomous Reactor (SUPERSTAR) is being developed at Argonne National Laboratory for international or remote deployment on growing electrical grids integrating lessons learned, innovations, and best features from the previous STAR-LM, SSTAR, and ELSY concepts. Initial efforts are focused on a near-term deployable SUPERSTAR demonstrator (demo) representing a first-of-a-kind deployment. Key new features of a SUPERSTAR demo concept including a long lifetime fissile self-sufficient converter core incorporating particulate-based metallic fuel, low pressure drop Intermediate Heat Exchangers incorporating compact diffusion-bonded Formed Plate Heat Exchanger technology exposing the reactor vessel to only cold Pb coolant, and a natural circulation Heavy Liquid Metal Coolant intermediate heat transport circuit are shown to be viable.
