DNFE3 - Victor Prost, from Renaissance Fusion

Victor Prost, Deputy Head of the Magnet Vacuum and Coating Group at Renaissance Fusion, discusses the startup’s mission to deliver low-cost fusion energy. Based in the south of France, Renaissance Fusion focuses on developing stellarators, a type of magnetic confinement fusion device. Prost explains the advantages of stellarators over tokamaks, highlighting their steady-state operation and simpler maintenance. He also details the use of high-temperature superconductors and liquid first walls to enhance efficiency and durability. The presentation covers Renaissance Fusion’s innovative approach to simplifying the construction and operation of stellarators. Prost outlines the company’s three main pillars: advanced superconductors, liquid first walls for heat transfer and radiation shielding, and laser-engraved circuit patterns on cylindrical structures. These technologies aim to make fusion energy more accessible and reliable, addressing the growing global demand for clean energy.
