X-energy and SGL Carbon to Expand Nuclear-Grade Graphite Production Capacity
X-Energy and SGL Carbon announced on August 3 that they have signed a binding agreement to expand production capacity for NBG-18 medium-grained isotropic nuclear-grade graphite. NBG-18 is a critical specialty material for X-Energy's Xe-100 high-temperature gas-cooled reactor, supporting the company's subsequent commercial project deployments. Under the agreement, X-Energy will invest up to $8 million in phases to support the construction of new facilities and equipment upgrades at SGL Carbon's plant in Chedde, France. Upon completion of the expansion, the plant will be capable of producing graphite billets annually sufficient for up to eight Xe-100 reactors. SGL Carbon has also agreed to expand its graphite billet processing capacity in the United States to enhance the stability of this safety-critical material supply chain.
