Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The thermal performance of the first wall (FW) monoblock module, made from carbon fiber composite (CFC) or tungsten alloy with a castellated plasma phasing surface, was analyzed for runaway electron (RE) impact under reactor conditions. A water cooling system with Cu pipes embedded into the module is used. Calculations demonstrate that, in ITER, for an expected RE pulse duration [approximately]0.1sec and deposition energy of [approximately]30MJ/m2 , the heat generation in a W monoblock occurs within a thin surface layer ([approximately]10m) which, however, does not melt. In the CFC case, heat generation occurs deep in the bulk ([approximately]1000m), but CFC does not experience brittle destruction. The intense X-ray radiation caused by runaways is strongly attenuated within a 10-mm-thick layer of W and does not pose any threat for the cooling system. For the CFC case, a small but significant heat generation caused by the RE can occur in the Cu pipe.
