NRC Completes Safety Review of X-energy's Xe-100 SMR | X-energy

The Nuclear Regulatory Commission finalized its safety evaluation report for X-energy's Xe-100 high-temperature gas-cooled reactor design. The review clears the technical path for the proposed Long Mott Generating Station in Texas, marking the first time an advanced reactor design has reached this stage for an industrial site.

The milestone establishes a regulatory precedent for future small modular reactor projects using the NRC's risk-informed framework. The design relies on passive safety features and TRISO-X fuel particles to reduce the required emergency planning zone, potentially allowing commercial nuclear plants to be constructed closer to industrial facilities and energy consumers.
