X-energy raises $700M in latest funding round
Advanced reactor developer X-energy has announced that it has closed an oversubscribed Series D financing round of approximately $700 million. The funding proceeds are expected to be used to help continue the expansion of its supply chain and the commercial pipeline for its Xe-100 advanced small modular reactor and TRISO-X fuel, according the company.

An analysis of a conceptual design for a 1000-MW(e) Settled-Bed Fast Reactor fueled with UC and PuC spheres and cooled by liquid sodium has been made to determine its technical and economic feasibility. The study includes a reactor physics analysis, an engineering design and analysis of the thermal and hydraulic characteristics, and a study of the system economics. The study shows that there are no inherent technical problems for a settled-bed fast reactor of this size. Total power-generating costs were shown to be as low as 3.84 mills/kWh for fuel leased from the AEC and 4.14 mills/kWh for fuel that is privately owned.
