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.

Los Alamos National Laboratory has completed the conceptual design of the Materials Test Station (MTS), an accelerator-driven neutron source for irradiating nuclear fuel and materials in a fast neutron spectrum. In many respects, the irradiation conditions in the MTS are quite similar to those experienced by the first wall of a fusion reactor. Calculated He-to-dpa (displacements per atom) ratios range from 35 down to 5 appm He/dpa, allowing for critical testing of helium effects on mechanical properties under fusion-relevant conditions. We present here a brief history on the assessment of spallation sources for fusion materials testing and discuss irradiation conditions in the MTS as they pertain to testing materials for fusion reactor applications. In particular, we examine the production of spallation residues in the MTS for the fusion reactor candidate alloy EUROFER97 and compare the concentrations of these transmutation elements to those predicted for a fusion reactor first wall. We show that predicted yields of phosphorous and sulfur in steel alloys irradiated to high dose in fusion-relevant regions of the MTS are below typical as-fabricated concentrations.
