With central banks signaling tighter policy, energy security concerns, inflation worries and mixed growth signals across regions, many investors are looking for assets tied to essential infrastructure and long term power needs. Nuclear energy stocks sit at the crossroads of reliable baseload electricity and efforts to reduce emissions, and the Nuclear Energy Stocks screener helps you filter this space, from uranium suppliers to reactor operators. Using this tool, the focus here is on three stocks currently highlighted in the screener, and what their business models and risk profiles could mean for a diversified portfolio.

NuScale Power (SMR)

Overview: NuScale Power is a nuclear technology company that designs and supports small modular reactors. Each NuScale Power Module targets up to 77 megawatts of electricity, and the company offers a full suite of services from licensing and plant design to fuel management and outage support.

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

Market Cap: US$3.61b

NuScale Power attracts attention because it sits at the center of two themes: nuclear power for grid reliability and rising energy demand from AI heavy data centers. The company holds NRC approval for its small modular reactor design and is involved in projects such as Romania’s RoPower plant and the TVA linked ENTRA1 initiative. These may translate technical progress into long term contracts. At the same time, investors need to weigh ongoing losses, financing needs, and the reliance on converting complex agreements into actual orders, especially after recent quarters with lower revenue and larger net losses. For investors willing to accept higher execution and funding risk, NuScale provides a focused way to gain exposure to potential nuclear infrastructure build out.

NuScale Power sits where nuclear reliability meets AI driven electricity demand, yet the full story is not in the headlines. Get the 1 key reward and 3 important warning signs to see what could shift the balance next.

Constellation Energy (CEG)

Overview: Constellation Energy is a large U.S. power producer that generates and sells electricity, natural gas, and energy solutions using a mix of nuclear, wind, solar, natural gas, and hydro assets, serving everyone from big data centers and industrial customers to households. Its roughly 31,676 megawatts of capacity make it a central player in supplying low carbon, around the clock power.

Operations: Constellation Energy generates about US$29.9b in revenue from its Generation segment, reflecting its core focus on producing electricity across its fleet of nuclear and other power assets.

Market Cap: US$95.7b

Constellation Energy stands out in the Nuclear Energy Stocks screener because it combines a large nuclear fleet with long term contracts linked to hyperscaler data centers and corporate buyers that want carbon free electricity, backed by federal nuclear credits that support cash flow visibility. At the same time, investors need to factor in high debt levels, earnings that have been affected by a US$2.0b one off gain, and exposure to regulatory and decommissioning costs on aging nuclear plants. With the Calpine acquisition, planned Three Mile Island restart, and new gas and renewable projects coming online, the mix of potential growth and concentrated risks raises the question of how durable these new earnings streams could be as markets, policy and customer needs evolve.

Constellation Energy’s nuclear scale and long term data center contracts could be masking an underappreciated earnings story. Get the 4 key rewards and 2 important warning signs and see what might tilt this balance sooner than most expect

Paladin Energy (ASX:PDN)

Overview: Paladin Energy is an Australia based uranium company focused on developing and operating uranium mines, led by its Langer Heinrich project in Namibia, with additional exploration assets in Canada and Australia that support a long potential production pipeline.

Operations: Paladin Energy currently generates about US$248.5 million in revenue from its Namibian operations.

Market Cap: A$4.8b

Paladin Energy sits in a sweet spot for investors looking at nuclear linked opportunities, as its restarted Langer Heinrich mine is now producing and recent results show sales of US$209.05 million and a small profit of US$1.65 million over the nine months to March 31, 2026 after earlier losses. The company has long term uranium offtake contracts that can provide revenue visibility. At the same time, the stock trades on a rich P/S multiple, relies entirely on higher risk external funding, and has seen insider selling and a relatively new management team, which all make execution and valuation key issues to watch closely.

Paladin Energy’s restarted production, revenue of US$248.5 million and recent profit may suggest a story that many investors are not fully pricing in yet. Read the 2 key rewards and 1 important warning sign
