"This is the first commercial-scale, advanced nuclear plant to receive this permit. We plan to start construction on the Natrium plant in the coming weeks. Plans, of course, mean little when you've yet to build a working reactor."
"Natrium reactors like TerraPower's design require high-assay, low-enriched uranium (HALEU) fuel, as opposed to standard low-enriched uranium that's used in traditional nuclear reactors. The US has long lacked a steady HALEU fuel supply, and while that's starting to improve, most of the small handful of HALEU-enriching firms have yet to scale beyond pilot-level fuel production."
"TerraPower's fast reactor design uses liquid sodium as a cooling agent and incorporates molten-salt energy storage, which is designed to be safer since it operates at low pressure and can rely on natural convection of the sodium coolant to help cool the reactor in the event of a failure."
TerraPower has received Nuclear Regulatory Commission authorization to issue the first reactor construction permit in a decade for its Natrium facility in Kemmerer, Wyoming. The fast reactor design uses liquid sodium cooling and molten-salt energy storage, operating at low pressure with natural convection safety features. However, significant obstacles remain: TerraPower has never built a commercial-scale advanced reactor before, and the project requires high-assay, low-enriched uranium (HALEU) fuel. The United States currently lacks a steady HALEU supply, with enrichment firms operating only at pilot production levels. Commercial HALEU availability is not expected until the end of the decade. TerraPower has secured several HALEU deals since breaking ground, but long-term fuel reliability remains uncertain.
