The U.S. Nuclear Regulatory Commission approved a construction permit for TerraPower’s sodium‑cooled commercial reactor in western Wyoming, clearing the way for construction to begin within weeks on a project TerraPower estimates could cost up to $4 billion and target completion by 2030. The 345 MW design (peaking near 500 MW) is intended to power up to ~400,000 homes and potentially supply data centers tied to AI demand; the milestone reduces regulatory uncertainty but execution, fuel‑sourcing (highly enriched uranium historically from Russia), spent‑fuel policy and construction risk remain key near‑ and medium‑term risks for investors tracking nuclear infrastructure and clean‑power supply chains.
Market structure: TerraPower’s permit crystallizes a long‑duration demand signal for uranium, enrichment services and specialty nuclear engineering. Direct winners: uranium miners/ETF exposure (CCJ, URA), nuclear OEMs and service providers (BWXT, FLR) and hyperscalers (MSFT) that can secure low‑carbon baseload; losers: merchant gas/peaking generators and coal miners where new nuclear displaces marginal baseload over years. At scale (345–500 MW; $3–4bn capex) the per‑kW economics (~$8k–$11.6k/kW) keep near‑term price competition intact but tighten long‑term uranium/SWU supply and capex financing needs.
Risk assessment: Tail risks include regulatory/legal injunctions or spent‑fuel political blocks (20–30% chance of multi‑year delay), cost overruns >50% and fuel‑supply shocks if domestic enrichment lags (probability ~10–25%). Immediate market moves (days) will be headline driven and confined to equities; 6–36 months sees re‑rating as supply contracts and DOE policy evolve; full project realization is a 2030+ outcome with binary commissioning catalysts. Hidden dependencies: enrichment capacity (SWU), HEU sourcing alternatives, and municipal/state opposition to waste storage could create non‑linear delays.
Trade implications: Tactical direct plays: overweight URA/CCJ and buy select supplier equities (BWXT, FLR) with 12–36 month horizons; allocate small concentrated sizes (1–3% each) given binary permit/operational risk. Use pair trades—long CCJ vs short BTU—to express uranium upside vs coal secular decline; implement options to buy optionality (12–36 month LEAPS on CCJ or URA) and size with strict stop losses (–25%) and profit targets (+40–80%). Treasury/credit: expect higher utility capex issuance and modest widening in BBB utility spreads if multiple new nuclear builds follow.
Contrarian angles: Markets underweight the scale and duration mismatch — investors overestimate near‑term impact on power prices but underprice enrichment bottlenecks and long payback. The $/kW math suggests nuclear is a multi‑decade structural play, not a quick win for data centers; early alpha likely in enrichment/SMR‑service providers rather than broad utility ownership. Historical parallel: 1970s–80s build cycles show high cancellation/delay rates; plan for 20–40% downside on equity builds if supply/regulatory catalysts slip.
