Key chokepoints & investor context

Enrichment is the critical bottleneck. Russia holds 44% of global capacity — more than all Western enrichers combined. The US banned Russian LEU imports in 2024 (through 2040), but Western capacity won't close the gap until ~2028–30. SWU spot prices hit record highs of ~$170/SWU in 2024.

Russia is uniquely vertically integrated. Rosatom spans mining → conversion → enrichment → fuel fabrication → reactor construction → financing. No Western entity matches this. Cameco's $8.2B acquisition of Westinghouse (2023) was the closest attempt at building a Western counterpart.

China is building self-sufficiency. With 32 reactors under construction (half the global total) and growing domestic capacity at every supply chain stage, China is systematically reducing import dependency. CNNC enrichment capacity is expanding rapidly — watch the “China” column fill in over the next decade.

The US has gaps at every mid-stream stage. Scan the USA column: 1% of mining, 17% of conversion, 11% of enrichment. The US is the world's largest nuclear power consumer but relies almost entirely on imports for its fuel. Federal investment ($3.4B in LEU contracts, HALEU funding) is attempting to rebuild domestic capacity.
