FAST nuclear fusion project

conceptual design completed

The FAST project is a nuclear fusion initiative in Japan focusing on a compact, integrated fusion reactor design using a low-aspect-ratio tokamak. It aims to generate and sustain burning plasma with a fusion output of approximately 50 MW, incorporating energy conversion, fuel breeding cycles, and heat extraction systems into a single operational unit. The project uses high-temperature superconducting (HTS) magnets, liquid breeding blanket systems, and efficient tritium fuel cycle systems, with collaboration from public and private sectors domestically and internationally.
