3 Nuclear Stocks to Watch in October 2026: Standard Nuclear, Cameco, TKMS and the AI Power Demand Story

Simply Wall St's October 2026 list covers three companies tied to nuclear power as AI data centers push up electricity demand. Standard Nuclear makes TRISO fuel for small modular reactors, Cameco supplies uranium and fuel services, and TKMS builds submarines and naval systems for nuclear-powered fleets. The article argues that constant low-carbon power will become scarce, which could benefit the nuclear supply chain. The piece is more of a screener teaser than deep analysis. It points to a 'Nuclear Renaissance' screen and links to longer narratives for each stock. It also includes a disclaimer that it is not financial advice. Readers should note that TKMS is a defense contractor, not a clean energy company, and that SMR fuel demand is still tied to reactor deployments that are years away. Useful as a starting point, not a recommendation.

Interesting that the nuclear fuel supply chain is getting attention. TRISO for SMRs is still niche, but if data center demand pulls forward orders, Standard Nuclear could be one of the few pure plays. The article doesn't dig into actual offtake agreements though, so the revenue ramp is still speculative.

The article frames nuclear as always on power, but it skips interconnection and construction timelines. Fuel supply matters, but SMR deployment is still years out. I would want to see how much capacity is actually contracted versus just planned.

Cameco's contract floors and ceilings are the real story. Utilities locking in uranium at high prices tells you they expect tight supply. But the article mixes naval nuclear with civilian power, TKMS is not a clean energy play just because it builds submarines. Different demand driver, different policy risk.

No mention of cost per MWh or how TRISO fuel pricing compares to conventional fuel. Nuclear has a waste and cost problem that fuel suppliers don't solve by themselves. Worth reading the full narratives, but this list is a starting point, not an investment thesis.
