General Atomics Roadmap for an Advanced Tokamak Fusion Pilot Plant

General Atomics is pursuing an integrated advanced tokamak fusion pilot plant design and a technology roadmap that combines plasma physics optimization with practical engineering considerations. In order to contribute to electricity demands expected in a low-carbon energy market, fusion science and technology must be rapidly advanced and demonstrate the capability and attractiveness of fusion power. Key considerations are given to maturing the technology required for a fusion pilot plant, and defining the pilot plant's role in maturing a first-of-a-kind commercial fusion power plant. General Atomics has the expertise and capability to raise the readiness of critical fusion technologies. We find that power extraction and tritium breeding may benefit from the use of SiC-based materials, which offer advantages for the blanket concept with inherent safety benefits and high-temperature compatibility for high thermal efficiency. Benefits and challenges associated the fusion core are well known, and therefore the implications of design choices on reliability, maintenance, safety and supply chain require increased attention and will be discussed.
