Finding fusion’s place
Fusion energy is attracting significant interest from governments and private capital markets. The deployment of fusion energy on a timeline that will affect climate change and offer another tool for energy security will require support from stakeholders, regulators, and policymakers around the world. Without broad support, fusion may fail to reach its potential as a “game-changing” technology to make a meaningful difference in addressing the twin challenges of climate change and geopolitical energy security.
The process of developing the necessary policy and regulatory support is already underway around the world. Leaders in the United States, the United Kingdom, the European Union, China, and elsewhere are engaging with the key issues and will lead the way in setting the foundation for a global fusion industry.

Tungsten was joined to ferritic-martensitic steel (FMS) for application in a plasma facing component. Zirconium foil was investigated as an interlayer material for the joining of W to FMS. Repeated hot isostatic pressing (HIP) was conducted for the fabrication of W/FMS joints. The first HIP was performed at 950°C under 100 MPa for 1.5 h (diffusion joining stage), and the second HIP was executed at 750°C under 70 MPa for 2 h (tempering stage). The Zr interlayer formed a sound interface between W and FMS with no observable pores and cracks. The joining strength of W/FMS measured by a shear test was about 54 MPa. Elemental diffusion was observed along the hetero-interfaces of W/Zr and Zr/FMS. At the W/Zr interface, a thin layer of W–Zr inter-phase was observed. At the Zr/FMS interface, no intermetallic compound was formed, however, fine Zr grains featuring body-centered tetragonal lattice structures were formed near the interface.
