Our Pick Of The Best Nuclear Stocks In September 2026

Energy headlines are being rewritten after the US passed sweeping sanctions that allow tariffs of up to 100% on major buyers of Russian oil and gas. When big parts of the world face higher or less certain fuel supply, reliable baseload power suddenly looks more valuable. This article walks through three nuclear focused stocks from our clean power screener that could help investors respond to that shift.

The three stocks below are just a small sample from the nuclear energy theme, and the full screen surfaced 34 more listed businesses with equally detailed narratives that are not covered here.

To go broader and identify your own highest conviction ideas, head straight into the Nuclear Energy Stocks screener.

NuScale Power (SMR)

Overview: NuScale Power develops small modular light water reactors and bundled services that help utilities build, license, operate, and maintain nuclear power plants.

Operations: NuScale Power reports about $11 million in revenue, currently all from electric utility related activity in the United States.

Market Cap: US$3.9 billion

NuScale Power matters in this nuclear energy screen because it is not only designing a small modular reactor, it is also offering a full-service package to help turn that technology into operating, grid connected baseload power.

"NuScale's involvement in the RoPower 6-module small modular reactor (SMR) power plant in Romania indicates future meaningful revenue and cash flow through its partnership in the Fluor-led Front-End Engineering and Design (FEED) Phase 2."

What really moves the needle from here is how one unresolved piece of customer commitment risk ultimately feeds through to long run cash generation.

That uncertainty is exactly what makes the full narrative for NuScale Power so useful. It spells out how customer commitments, capital needs, and project timing could reshape the risk reward profile.

Constellation Energy (CEG)

Overview: Constellation Energy operates a large US power generation portfolio anchored by a significant nuclear fleet, selling electricity and related energy solutions to utilities, businesses, public entities, and households.

Operations: Constellation Energy generates about US$31.3b from its Generation segment, supplying power across regions including the Midwest, Mid-Atlantic, New York, ERCOT, and other US markets.

Market Cap: US$90.2b

Constellation Energy matters in this Nuclear Energy Stocks screener because its commercial reactor fleet turns the theme into grid scale, carbon free baseload power that large customers can actually contract today.

"Growing demand for carbon-free, reliable power from large-scale customers such as data centers (Meta, Microsoft) and corporates (Comcast), driven by digitalization, electrification, and decarbonization goals, is creating new, longer-term, higher-margin contracts with price premiums. These developments could result in significant changes to revenue and earnings as more transactions close."

What could really shift the story is how one less visible change in contract structure filters through to pricing power and long term margins.

That contract shift is the real hinge, and the full narrative for Constellation Energy shows how Constellation Energy’s pricing power, risk sharing, and upside potential could be evolving behind the scenes.

GE Vernova (GEV)

Overview: GE Vernova is an energy equipment and services group whose Power segment supplies nuclear steam turbines, plant equipment, and grid solutions worldwide.

Operations: GE Vernova generates about US$21.0b from Power, US$12.2b from Electrification, and US$8.5b from Wind, with minor intersegment eliminations.

Market Cap: US$246.3b

GE Vernova gives this nuclear energy screen exposure to the less visible equipment behind reactors, from steam turbines to long term plant services that keep baseload units running for decades.

"In Q1 2026 alone, GE Vernova reportedly secured $2.4 billion in data-center-related electrification orders, which is more than all of 2025 combined."

What really matters now is how one shift in long duration service mix shapes margins as that order backlog converts into cash.

As that mix tilts toward longer service work, the full narrative for GE Vernova explains in detail how GE Vernova’s backlog, cash conversion, and risks could be quietly accelerating.
