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.

The neutronics characteristics of four possible driver fuels for the Fast Test Reactor (FTR) are compared. The fuels investigated are PuO2-SS and UO2-SS cermets and PuO2-238UO2 and UO2-238UO2 ceramics. Since a high flux is of paramount importance in a test reactor, low-inventory plutonium-fueled cores are found to be quite attractive for use in the FTR. For core volumes of approximately 600 liters, cermet fuels offer a higher neutron flux and a larger shutdown coefficient than oxide ceramic fuels. If the latter fuels are used, BeO could be added to enhance the Doppler coefficient.
