Nuclear Fuel-Cycle Stocks

Fuel cycle
Conversion, enrichment, fuel fabrication and fuel technology: the steps between mined pounds and a loaded assembly. Economics ride capacity, contracts and technology milestones, so resource metrics do not apply.

- Who belongs here
- Listed companies whose business is a nuclear value-chain step other than mining: the fuel cycle (conversion, enrichment, deconversion and HALEU, fuel fabrication, fuel technology, isotope separation), reactor vendors and SMR developers, utilities with nuclear fleets, and nuclear services. They are tracked separately from miners because their economics ride capacity, contracts, licensing and technology milestones rather than pounds in the ground, so none of the resource-based screener metrics (EV/lb, cost, margin) apply. Inclusion is rule-based: a primary listing on a US, UK, Australian or Canadian exchange with a resolvable quote; no overlap with the miner, explorer or fund universes; and a cited materiality statement. Utilities qualify at 2 GW of owned nuclear capacity or nuclear at 15% of owned capacity, cited to the 10-K properties table.
- Materiality
- Every company carries a materiality tier with the filing that proves it: pure play, a reportable nuclear segment, or diversified (nuclear is a named but small line). Diversified companies show a badge and never enter stage totals or rankings, so a conglomerate cannot be read as a nuclear proxy.
- Market caps and prices
- Computed live from the primary listing via EODHD (shares x price x FX) and never stored. A row degrades to its cited facts alone when live data is unavailable, never an estimated cap.
- Joined figures
- Facilities, SMR projects, datacenter deals, DOE awards, Reactor Pilot Program milestones and operated reactor fleets are not copied into this dataset. Each company lists exact-match alias keys into the site's cited datasets and the figures are joined when the page renders, so an update to the source dataset reaches every company page in the same deploy. A test fails if an alias matches nothing. Reactor fleet figures come from Global Energy Monitor's Global Nuclear Power Tracker (CC BY 4.0) and are labelled operated site capacity, never ownership share.
- Citations
- Every stated fact links the company page or disclosure that states it. Facts are structural (what the company does, where, with whom); figures that change with each quarter belong to the company's filings, not this dataset. Every row records the date of its last human review.
