Nuclear energy stocks are back in focus as investors look for reliable power solutions in a world shaped by volatile commodity prices, shifting interest rate paths, and energy driven inflation risks. While oil markets and geopolitical tensions keep energy costs in the spotlight, nuclear power sits at the crossroads of energy security and lower carbon electricity. This curated Nuclear Energy Stocks screener helps you cut through the noise by highlighting companies linked to uranium supply, fuel enrichment, and reactor operations. Below, you will find three stocks from the screener that stand out based on business focus, balance of risks, and theme exposure.

NuScale Power (SMR)

Overview: NuScale Power is a nuclear technology company that designs and supports small modular reactors, each NuScale Power Module producing up to 77 megawatts of electricity, for utilities and other large power users. Beyond the reactors themselves, NuScale sells licensing, design, construction, operations, maintenance, training, and fuel management services that span the full life of a nuclear power plant.

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

Market Cap: US$3.0b

NuScale Power attracts attention because it sits at the center of small modular reactor deployment, with NRC certified technology, partnerships like ENTRA1 and RoPower, and projects that could eventually serve power hungry data centers. At the same time, the company is still in a pre profit phase, with a small current revenue base and ongoing losses. Its dependence on external funding, future power purchase agreements, and complex regulatory milestones adds meaningful risk. For investors interested in nuclear exposure, NuScale offers a concentrated way to focus on SMR commercialization. The key considerations include how contract wins, funding arrangements, and execution on early projects could affect the balance between its growth potential and its financing and delivery risks.

NuScale Power sits at the intersection of SMR ambition and real world execution, but the full risk reward picture is not obvious from headlines alone. For more detail, review the 1 key reward and 3 important warning signs

Constellation Energy (CEG)

Overview: Constellation Energy is a US based power producer and retailer that supplies electricity, natural gas, and low carbon energy solutions from a fleet of nuclear, wind, solar, natural gas, and hydro plants to utilities, businesses, governments, and households. With roughly 31,676 megawatts of capacity, it connects large carbon free generation with customers seeking reliable, long term energy contracts.

Operations: Constellation Energy generates US$29.9b of revenue from its Generation segment, which aggregates earnings from power production across regions including the Midwest, Mid Atlantic, New York, ERCOT, and other power markets.

Market Cap: US$98.0b

Constellation Energy is notable in nuclear focused investing because it couples a large carbon free fleet with long term contracts to power energy hungry AI data centers and blue chip corporates such as Microsoft, Meta, and Walmart. Analysts highlight that these 15 year plus power purchase agreements, federal nuclear tax credits, and planned nuclear uprates and restarts support higher margin, more predictable cash flows, even as the company carries a sizable debt load and has benefited from recent one off gains. For investors, the appeal is a mix of potential undervaluation relative to estimated fair value and a growing role in 24/7 clean power. This is balanced against regulatory, customer concentration, and balance sheet risks that may warrant closer inspection.

Constellation Energy’s long term AI and corporate power contracts hint at a story that many investors may be only half seeing right now, with the 4 key rewards and 2 important warning signs that could change how you think about its nuclear cash flows

Oklo (OKLO)

Overview: Oklo is a US based nuclear company developing compact Aurora Powerhouse fission plants that aim to supply 15 to 75 megawatts of electricity directly to customers through long term power contracts, rather than selling reactors outright. It is also working on fuel recycling and fabrication technology to turn used nuclear fuel into new fuel for its own reactors.

Market Cap: US$7.0b

Oklo attracts attention because it is pitching a vertically integrated model that combines small reactors, recycled fuel, and long dated electricity contracts for power hungry users such as AI data centers. This model is backed by partnerships with groups like Nvidia and Meta and a reported US$1.6b cash position plus US$600m in marketable equities. At the same time, the company is pre revenue with recent net losses, no commercial plants in operation, a history of regulatory setbacks, and a share price that has been volatile and has lagged the US Electric Utilities industry. For investors, the tension between rapid regulatory milestones, DOE backed programs and insider selling, dilution, and high reliance on external funding creates a complex opportunity that deserves closer inspection.

Oklo’s ambitious fuel recycling plans, cash reserves, and AI data center focus could be masking a very different risk profile than many investors assume. Start with the 1 key reward and 5 important warning signs (1 is major!)
