SGL Carbon has received an additional order worth approximately US$90 million to supply nuclear graphite for X-energy’s Xe-100 reactors. The supplier announced the agreement on 29 October.
The order covers NBG-18 medium-grain isotropic graphite for the high-temperature gas-cooled reactor design. SGL says production of the new billets will begin at the end of 2026.
This is the second commercial order under the companies’ existing framework. Components for their first commercial project, involving X-energy and Dow at Seadrift, Texas, have already been delivered, according to SGL.
The companies agreed in August to expand billet production at Chedde in France and machining capacity at St Marys in the United States. The new order gives that specialist supply chain additional contracted work.
The release does not allocate the latest order to a named reactor site or disclose a new plant investment decision. It is a component-supply milestone, not confirmation that an Xe-100 reactor has entered operation.
