X-energy, SGL Carbon Announce Capacity Expansion for Nuclear-Grade Graphite
X-Energy, Inc. and SGL Carbon announced a binding agreement to double SGL's production capacity for NBG-18 medium-grain isotropic graphite, a material central to X-energy's Xe-100 high-temperature gas-cooled reactor. The expansion doubles the EU supply chain for graphite billet production and increases manufacturing capacity for this long-lead material.
Why it matters — A more robust supply of nuclear-grade graphite reduces a key long-lead material risk for X-energy's Xe-100 reactor program.
