US NRC completes safety review of Xe-100 SMR planned for Texas

· Energy · United States

The US Nuclear Regulatory Commission has finished its safety review of the Xe-100 reactor, which is proposed for deployment at the Long Mott Generating Station in Texas, and says a construction permit announcement will follow soon. The Xe-100 is a high-temperature gas-cooled small modular reactor design. The step moves one of the leading US small modular reactor projects into its final permitting stage, a key gate before construction can begin. Progress on SMR licensing is closely watched by utilities and investors weighing nuclear as a source of firm, low-carbon power for growing electricity demand.

Why it matters：Licensing progress on small modular reactors determines whether nuclear can scale as firm low-carbon capacity for data centers and grids.

Key points

  • NRC finished safety review of the Xe-100
  • Proposed site is Long Mott Generating Station in Texas
  • Construction permit announcement expected soon
