XENITH
X-energy's transportable high-temperature gas-cooled microreactor point design, in NRC pre-application review since November 2023 (docket 99902118); the NRC gives a range of 3 to 10 MWe, so no single rating is stored. This dated design profile does not establish current development, a deployment site or any regulatory permission.
