📈 Demand Impact

Why this matters for uranium

Every reactor under construction represents ~0.39M lbs U3O8/yr of incremental demand once it reaches commercial operation — demand that does not yet exist in the spot or term market. The 59 reactors currently under construction will add 27M lbs/yr to annual world demand when complete — equivalent to adding 15% to current world production of ~175M lbs/yr. The planned pipeline adds another 22M lbs/yr beyond that. None of this demand is reflected in current utility contracting books.

Under construction — 59 units · 66.5 GWe · 27M lbs/yr at full build-out

These reactors have poured first concrete or are in active nuclear installation. Expected commercial operation dates are builder estimates — assume 12–24 month slippage for non-Chinese projects. China is executing at ~6 units/yr and consistently hits schedule. Rosatom projects (Turkey, Egypt, Bangladesh) are running 18–36 months behind. UK (Hinkley) has slipped repeatedly and is now targeting 2030+ at £35B+ cost.

Planned & approved — 59 units · 54 GWe · 22M lbs/yr incremental

These projects have government approval, signed agreements, or firm developer commitments, but have not yet broken ground. Assume 50% execution rate on these numbers — slippage, cancellation, and financing failure are common outside of China. Even at 50%, this pipeline adds ~11M lbs/yr to world demand — roughly 6% of current production.

SMRs — 9 projects · 2.05 GWe tracked · near-term demand impact is small but catalytic

Individual SMRs are small (227 MWe average here). Demand impact before 2032 is minimal — but SMR fuel orders create new enrichment and conversion demand ahead of operation. TRISO and metal fuel designs (Kairos, Oklo, TerraPower) use High-Assay Low-Enriched Uranium (HALEU) — a fuel type with virtually no civilian supply chain today. The enrichment bottleneck could pull uranium demand forward. Watch: Centrus/DOE HALEU production contract and whether Russia's TENEX ban removes the only current HALEU source.

Incremental demand model — under construction reactors only

Assumes LWR: 0.050 lbs U3O8/MWh, PHWR: 0.065 lbs/MWh, 90% capacity factor. Demand shown is the annual run-rate once each cohort reaches commercial operation. These are incremental to today's ~175M lbs/yr world demand. The 2026–2028 cohort alone adds ~13M lbs/yr — equivalent to starting up a second Cigar Lake. Against a mine supply curve that grows ~3M lbs/yr in optimistic scenarios, this pipeline demand accelerates the structural deficit materially.
