Nuclear energy stocks sit at the crossroads of two forces that many investors care about right now: energy security and reliable, low carbon power in a world where inflation trends, interest rate expectations and geopolitics keep shifting. The Nuclear Energy Stocks screener cuts through the noise by focusing on companies tied to uranium supply, fuel enrichment and reactor operations that are central to this theme. In this article, you will see three stocks from the screener that show how different parts of the nuclear value chain can fit into a diversified portfolio.

NuScale Power (SMR)

Overview: NuScale Power develops and supports small modular nuclear reactors that can produce up to 77 megawatts of electricity per module, aimed at utilities and other customers that want reliable low carbon power in smaller, scalable units. Alongside the reactor technology itself, NuScale sells a full suite of services that covers licensing, plant design, construction support, operations, maintenance, fuel management and staff training.

Operations: NuScale currently generates US$18.7 million in revenue from electric utility related services, all from customers in the United States.

Market Cap: US$3.1b

NuScale Power is drawing attention because it already holds U.S. Nuclear Regulatory Commission approval for its SMR design. This positions it ahead of many early stage nuclear peers in the race to supply reliable baseload power to utilities and energy hungry data centers. Projects such as the RoPower plant in Romania and the proposed 6 gigawatt program with TVA and ENTRA1 Energy hint at potential multi gigawatt deployment if contracts and power purchase agreements are finalized. At the same time, the company is still pre profit with recent quarterly sales under US$1 million, ongoing losses and a funding mix that leans on higher risk borrowing and shareholder dilution. For investors who can accept that trade off, NuScale offers a concentrated way to get exposure to small modular reactor commercialization.

NuScale Power already has reactor approval and headline projects on the table, yet the real story sits in the fine print. Before you assume the upside is obvious, read the 1 key reward and 3 important warning signs.

Oklo (OKLO)

Overview: Oklo develops compact Aurora Powerhouse fission plants that are designed to supply 15 to 75 megawatts of electricity to U.S. customers, while also advancing nuclear fuel recycling so its reactors can use converted spent fuel rather than only freshly mined uranium.

Market Cap: US$7.1b

Oklo is attracting interest because it wants to own and operate its Aurora units and sell long term electricity contracts, rather than just ship reactors and walk away. That model could create recurring revenue if projects progress. It is supported by around US$1.6b in cash plus roughly US$600m in marketable equities and partnerships with companies such as Nvidia and Meta. At the same time, Oklo is still pre revenue with a recent US$33m net loss, no commercial plants running and a regulatory path that is progressing but not yet complete. Recent U.S. Department of Energy approvals for its Groves Isotope Test Reactor and selection for programs around surplus plutonium and AI data center power show why some investors are watching Oklo closely while others focus on execution risk.

Oklo’s plan to pair long term power contracts with nuclear fuel recycling has investors talking, but the real story sits in the details. Before you decide how it fits your watchlist, review the analysis report for Oklo

GE Vernova (GEV)

Overview: GE Vernova is an energy infrastructure company that helps generate, move, and manage electricity through three main segments covering power plants, wind turbines, and grid and storage solutions across multiple regions. Its products and services span gas and nuclear turbines, hydro and steam technology, wind farms, and the hardware and software that keep modern power grids running.

Operations: GE Vernova generates US$20.98b from Power, US$8.47b from Wind, and US$12.24b from Electrification, with a small offset from other and intersegment items.

Market Cap: US$261.5b

GE Vernova is attracting attention because it sits at the heart of rising electricity demand from AI data centers and grid upgrades, yet still offers exposure to long term servicing revenue backed by a very large installed base of gas turbines and a sizeable order backlog. Strong recent free cash flow and higher margins have pushed it closer to a high quality infrastructure profile, while its P/E remains below the wider electrical industry even after a strong run and analyst price targets that sit above the current share price. The flip side is a weaker Wind segment, a rich valuation against some cash flow metrics, and reliance on external borrowing. That mix of strengths and pressure points is exactly what makes the full GE Vernova story worth a closer look.

GE Vernova’s growing order book and rising margins suggest a story that many investors might still be underestimating. Before you assume the recent run has told you everything, read the 5 key rewards and 2 important warning signs
