The uranium and enrichment rungs ripped on a risk-on rotation — Denison +9.3%, Centrus +5.9%, NuScale +5.5% — while the Japanese heavy-forging chokepoint lagged.

The leader was Denison Mines (DNN), up 9.3% to $2.36 on renewed uranium-sector optimism — a clean morning push from roughly $2.11 to $2.35 — and it dragged the whole fuel-supply chokepoint with it. Thursday was a risk-on rotation day: after Wednesday's hot-CPI selloff in AI and chips, the Dow rose about 1.1% and capital rotated into heavily-sold speculative groups, with the uranium complex a prime beneficiary. Up the fuel cycle, Uranium Energy (UEC) rose 6.1% to $8.17, NexGen (NXE) 5.9% to $8.56 and Cameco (CCJ) 2.2% to $83.23, while the Sprott Uranium Miners ETF (URNM) added 3.2% to $43.78 and Energy Fuels (UUUU) 2.8% to $8.57.

The enrichment rung — the hardest physical bottleneck in Western fuel supply — led the move with the miners. Centrus (LEU) rose 5.9% to $127.01, the one name that can spin domestic HALEU centrifuges at scale. The SMR platform rung, the demand side of the same chokepoint, also rallied: NuScale (SMR) +5.5% to $6.15, NANO Nuclear (NNE) +4.5% to $13.59, Oklo (OKLO) +3.3% to $30.01 and Lightbridge (LTBR) +5.5% to $5.35 on its advanced-fuel work.

The laggard was Japan Steel Works (JPSWY), down 6.2% to $20.57 — the reactor-pressure-vessel forging chokepoint, one of a handful of foundries worldwide that can forge large-scale vessel components. The move tracked its Tokyo home line (5631.T, down about 6.5% on its October 15 session) in a broad Japanese industrials selloff rather than anything sector-specific. The session's other soft marks were on the enrichment-and-instrumentation edge: Silex (SILXY) −4.8% to $12.43, enCore Energy (EU) −3.5% to $0.82 and Mirion (MIR) −2.3% to $15.54.

The near calendar is dense into year-end. BWX Technologies reports Q3 on November 2 and NANO Nuclear closes its fiscal year November 15; the Xe-100 construction-permit NRC review hits an 18-month milestone around December 16. The structural catalysts are the year-end windows for the Westinghouse/US government definitive agreements and Bulgaria's Kozloduy Units 7–8 AP1000 final investment decision — both demand signals for the forging and fuel rungs that split today's tape. For the enrichment chokepoint specifically, the 2028 termination of Russian LEU import waivers remains the backdrop under Centrus's domestic case.
