Sources: 4. Developments: 2. X-Energy is positioning itself as a competitor in the small modular reactor (SMR) market, utilizing pressurized helium gas as a coolant for its XE-100 reactor design. While the company has faced recent financial volatility, including a decline in stock price and quarterly earnings that missed consensus estimates, it continues to attract investor interest driven by rising power demands. Recent developments show significant federal support for the company’s operations. The U.S. Department of Energy has notified X-Energy that it will receive up to $1 billion in additional funding through the Advanced Reactor Demonstration Program to support the deployment of four Xe-100 reactors at a facility in Seadrift, Texas. This brings the total federal support for the X-Energy and Dow collaboration to approximately $2.15 billion. Beyond reactor deployment, X-Energy is expanding its supply chain through agreements for uranium enrichment services and nuclear-grade graphite manufacturing. Additionally, the company received an $11 million economic development grant from Tennessee to support its fuel fabrication campus in Oak Ridge. ## Timeline ### 2026-08-22: X-energy to receive up to $1 billion for Texas reactor project X-energy will receive up to $1 billion in additional DOE funding for its Xe-100 small modular reactor project with Dow in Seadrift, Texas, bringing total federal support to $2.15 billion. 2 sources. https://clstr.news/cluster/x-energy-to-receive-up-to-1-billion-for-texas-reactor-project ### 2026-08-19: X-Energy enters competitive small modular reactor market X-Energy is competing in the growing small modular reactor market with its helium-cooled XE-100 design, despite recent earnings misses and stock price volatility. 2 sources. https://clstr.news/cluster/x-energy-enters-competitive-small-modular-reactor-market --- Cite as: X-Energy small modular reactor development.
