Compute is now constrained by electricity as much as by silicon. Hyperscalers are signing multi-gigawatt power purchase agreements, utilities are rebuilding long-dated fuel coverage, and the nuclear fuel cycle is becoming strategic again — not just cyclical. This theme tracks the companies selling into the nuclear fuel and reactor infrastructure layer.
Why it matters
- Load growth is real. Data centers, industrial electrification, and grid modernization are hitting the power system simultaneously. Generation and transmission both have to expand.
- Nuclear is back on the table. Utilities and new industrial buyers want reliable, Western-aligned baseload. That makes the uranium fuel cycle strategic again.
- Long lead times = order visibility. Uranium contracting and reactor component lead times give these companies unusually strong forward visibility.
Roster
- CCJ — Cameco — cleanest pure-play on the uranium fuel cycle, including fuel services and Westinghouse.
- BWXT — BWX Technologies — nuclear components for the U.S. Navy plus a growing commercial nuclear services business.
- LEU — Centrus Energy — domestic HALEU enrichment; leveraged to advanced-reactor programs and U.S. fuel-security policy.
What to watch
- Long-term uranium contracting cadence at CCJ — evidence that utilities are locking in multi-year coverage.
- HALEU production milestones at LEU — proof that domestic advanced-fuel supply is real.
- Hyperscaler nuclear PPAs — Meta/Microsoft/Amazon-style deals are the demand side of the theme.
- Nuclear plant restarts and new builds — restart announcements and SMR progress expand the addressable market.
- BWXT commercial nuclear services growth — a proxy for broader nuclear fleet investment beyond Navy programs.
