| Abstract Scope |
Improvements in plasma and magnet efficiencies can enable a cost-effective route to commercial fusion energy. Tokamak Energy is advancing this through the compact Spherical Tokamak (ST) design and operation of our tokamaks ST25, ST40, and future devices. Confidence in the next generation of STs necessitates effective material solutions for unprecedented challenges. This talk will focus on in-vessel components, including breeder blankets, central column, and plasma-facing component designs. These components must withstand plasma-material interaction, high fluxes of 14.1 MeV neutrons, hydrogen isotope permeation, liquid lithium compatibility, and high steady-state heat fluxes. Such conditions require materials that can deal with this harsh environment, and this presentation will showcase our development roadmap. Key partners will be highlighted, and case studies demonstrating some of this work will be presented.
The development of innovative materials is essential for advancing fusion technology, bringing us closer to a sustainable fusion future. |
