Nuclear energy stocks are back in focus as investors weigh mixed signals across inflation, growth, and interest rate expectations from markets as varied as Japan, Germany, Canada, and the UK. With energy costs featuring in producer prices, bond markets, and consumer budgets, this screener helps you zero in on companies linked to uranium supply, enrichment, and reactor operations that target reliable baseload power and lower emissions. In this article, you will see 3 stocks from the Nuclear Energy Stocks screener, with clear, practical takeaways to help you decide whether they deserve a closer look in your portfolio research.

NuScale Power (SMR)

Overview: NuScale Power develops small modular reactor technology, offering compact nuclear units that can supply grid scale or industrial power with lower emissions and continuous output, and supports customers through licensing, construction, training, and long term plant operations services.

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

Market Cap: US$4.29b

NuScale Power is drawing attention because it already holds an NRC approved small modular reactor design and is tied into potential multi gigawatt projects with partners like TVA and RoPower. This comes at a time when AI data centers are expected to increase electricity demand. Analysts note the possibility of higher revenues in the future, but NuScale is still loss making, relies on external funding, and faces uncertainty around long term power contracts, project financing, and supply chain execution. For investors, the combination of a regulatory lead, a large project pipeline, and policy support for nuclear exists alongside risks such as cash burn, share dilution, legal overhangs, and share price volatility, which makes understanding the full thesis especially important.

NuScale Power’s NRC approved design and multi gigawatt project pipeline could be masking the real swing factor for investors, so walk through the 1 key reward and 3 important warning signs and see what might change the story next

Constellation Energy (CEG)

Overview: Constellation Energy is a large US-based power producer that sells electricity, natural gas, and decarbonization solutions across multiple regions through a fleet of nuclear, wind, solar, gas, and hydro assets serving utilities, businesses, public sector entities, and households.

Operations: Constellation Energy generates all of its US$29.9b in revenue from its Generation segment, supported by regional operations across the Midwest, Mid-Atlantic, New York, ERCOT, and other US power markets.

Market Cap: US$97.9b

Constellation Energy stands out in the nuclear energy theme because its large nuclear fleet is already tied to long-term, carbon-free power contracts with hyperscalers like Microsoft and Meta. These contracts can provide premium pricing and more predictable cash flows compared with short-term wholesale markets. Federal production and zero-emission credits further support the economics of its fleet. Recent moves such as the Calpine acquisition and progress on restarting Three Mile Island indicate growing capacity that aligns with rising data center demand. The trade off for investors is meaningful leverage, exposure to shifting regulation, and dependence on a relatively concentrated customer base. The key question is how these long-dated contracts and policy supports compare with the operational and balance sheet risks over time.

Constellation Energy’s long term tech contracts and zero emission credits could be masking the real story for its cash flows, so walk through the 4 key rewards and 2 important warning signs to see what might really be driving this setup

GE Vernova (GEV)

Overview: GE Vernova is an energy infrastructure company that designs and services equipment and software for power generation, transmission, and storage, spanning gas and nuclear turbines, hydro and steam plants, wind turbines, grid gear, and electrification solutions across major global regions.

Operations: GE Vernova generates most of its revenue from Power at US$20.3b, followed by Electrification at US$10.8b and Wind at US$8.7b, with smaller eliminations and other items reducing the total by US$0.4b.

Market Cap: US$298.2b

GE Vernova is positioned within the AI and electrification build out, supplying the gas turbines, transformers, software, and grid equipment that power data centers and modern grids, and backing this with a large installed base that supports long term service revenue. Earnings have grown strongly in the last year, free cash flow is reported at multi billion dollar levels, and returns on equity are currently high, while the P/E sits below the Electrical industry average. Offsetting factors include a weaker Wind segment, heavy reliance on external borrowing, significant non cash earnings, and insider selling, all under a relatively new board. For investors, the key consideration is how that mix of Power and Electrification assets compares with these pressure points over time.

GE Vernova’s mix of high reported returns, multi billion dollar free cash flow, and a P/E below the Electrical industry average suggests investors may be missing something. Walk through the analysis report for GE Vernova to see what that combination could really mean for the story ahead.
