At least two new commercial nuclear fission reactors begin commercial operation in the United States before 2032.
US nuclear growth relies on small modular reactors following recent completions like Vogtle. Resolves true if NRC confirms two new commercial reactors reach regular commercial service.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 21%.
They do not agree: GPT puts it at 57% and Qwen at 9%, 48 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 22 Oct 2036, when the outcome is checked against sources and every number above gets a permanent score.

It hinges on whether one SMR developer converts NRC approvals and construction plans into two operating units on schedule.
- NuScale's first project collapsed, while TerraPower and X-energy still need licensing, financing, supply chains, and multi-year construction.
- Vogtle's 2023–24 units show U.S. completions are possible, but cost and schedule overruns make a second two-reactor success far from routine.
- Odds rise sharply if TerraPower's Natrium or Dow/X-energy reaches NRC construction approval and begins major nuclear-island work by 2028.

Hinges on whether SMR projects (TVA Clinch River, Kairos, X-energy) or uprated large reactors actually reach commercial service by 2032.
- Vogtle 3&4 took ~7 years late and billions over budget, showing US nuclear construction timelines are routinely blown past deadlines.
- TVA's Clinch River BWRX-300 targets commercial operation around 2033, and other SMR projects (Kairos, X-energy) are earlier-stage, making 2032 tight for two units.
- Strong federal policy tailwinds (DOE loans, bipartisan support, AI-driven power demand) raise odds versus historical base rate but licensing/construction risk remains…

Two US reactors must clear NRC licensing and construction in under six years; only Vogtle's AP1000s have done that this century.
- Vogtle 3 and 4 (2023, 2024) were the only US reactors to enter service since Watts Bar 2 in 2016, a base rate of roughly two per decade.
- NuScale's UAMPS project was cancelled in 2023, and no SMR has an NRC construction permit; TVA's Clinch River BWRX-300 is the furthest along, targeting 2032-2033.
- The one thing that would move this up is an NRC license approval plus first concrete pour for a US SMR before 2028, which no project currently has.

Success hinges on SMR developers like TerraPower and NuScale clearing NRC licensing and building two units in under five years.
- No commercial non-LWR reactor has ever completed NRC licensing and achieved commercial operation within a six-year window.
- TerraPower at Kemmerer and Kairos at Hermes face supply-chain bottlenecks and fuel availability constraints with HALEU by 2031.
- Even with ADVANCE Act regulatory streamlining, standard first-of-a-kind US nuclear construction averages extensive multi-year delays.

Only plants already in or near construction can finish by 2031; none of the SMR cohort is that far along.
- TerraPower Natrium and X-energy Xe-100 are the nearest commercial units, with nuclear-island work still years from start and 2030+ COD targets.
- US large-reactor precedent (Vogtle) ran 10+ years from first concrete; first-of-a-kind SMRs face extra NRC and supply-chain lag.
- A pair of FOAK plants both hitting commercial service inside five years would require unprecedented schedule compression that current dockets do not show.

Getting even one first-of-a-kind SMR to commercial operation by 2031 is aggressive; getting two from separate projects is near-impossible.
- TerraPower Natrium in Wyoming broke ground June 2024 targeting ~2030-31, but first-of-a-kind sodium-cooled designs face commissioning delays that could push past 2032.
- No second project has started construction; X-energy/Dow and NuScale lack firm timelines, and NRC licensing alone takes 3-5 years for new designs.
- Base rate: zero new US reactors reached commercial operation in any 5-year window since 1990; Vogtle 3&4 took ~15 years from COL to operation.
