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.

A. Selection, Production, and Development of Alloys for HTGR Component | Status of Metallic Materials Development for Application in Advanced High-Temperature Gas-Cooled Reactor / Material | doi.org/10.13182/NT84-A33455

Inconel-618E (54 Ni-23 Cr-6 W) was developed specifically to meet the requirements of the high-temperature gas-cooled reactor (HTGR). The alloy has good fabricability, weldability, and, above all, metallurgical stability. Alloy 618E is free of cobalt and aluminum. At temperatures of 954°C (1750°F) and higher, alloy 618E has stress rupture strength comparable to Inconel-617. At lower temperatures, the rupture strength of alloy 618E is somewhat lower than that of alloy 617. Alloy 617 remains the best-established alloy for HTGR service. However, alloy 618E does not have that material’s disadvantage of aluminum and cobalt content and may become a candidate for HTGR applications.
