I spoke at a Japan-U.S. workshop on liquid metal plasma-compatible materials.

On February 18th, Takuya Goto, co-founder and deputy CTO of Helical Fusion, spoke at the 6th US-Japan Workshop on Power and Particle Control in a Steady State Magnetic Fusion DEMO Reactor by Liquid Metal Plasma-Facing Components, held at the National Institute for Fusion Science.

This workshop was hosted by the National Institute for Fusion Science (NIFS) and held jointly with "Unexplored Physics and Chemistry of Liquid Metal Wall under Extreme Environment." Experts from Japan and the United States deepened discussions on the application of liquid metals as plasma counter materials in future fusion reactors .

Liquid metal technology is being considered as a promising option for addressing the high heat flux and particle loads expected in fusion reactors aiming for steady-state operation. Practical solutions for plasma-facing equipment are a crucial research area in designing for commercial reactors.

In the session,

• Liquid metal flow

• Liquid metal diverter concept and experimental facility

• Diverter heat flux relaxation and plasma-surface interactions

• Physical and chemical aspects at the boundary between liquid metals and solids

Practical discussions were held on these topics.

Helical Fusion has been rigorously addressing the "three requirements for practical power generation"—net power generation, steady-state operation, and maintainability—in order to bring fusion energy into practical use.

We will leverage this international fusion of knowledge to refine our design and steadily advance the verification phase.
