Oil price volatility linked to Middle East shipping routes keeps energy security at the center of market conversations. That backdrop puts nuclear energy stocks in sharper focus for investors who want power sources that are not tied to daily oil headlines. The Nuclear Energy Stocks screener filters this broad theme into a focused watchlist. In this article you will see three stand out stocks worth a closer look.

The three nuclear energy stocks in this article are just a starting sample, and the full screen surfaced 32 more companies with equally detailed narratives that are not covered here. To go deeper into the theme, identify your own candidates and analyze them side by side, head straight into the Nuclear Energy Stocks screener.

NuScale Power (SMR)

Overview: NuScale Power develops and services small modular nuclear reactors, offering its NuScale Power Module that can generate 77 megawatts of electricity for utilities and other large power users. The company also supports customers across the full plant lifecycle with licensing, design, construction, operations, maintenance, fuel management, and outage services, backed by partnerships such as its compressor collaboration with Ebara Elliott Energy.

Operations: NuScale Power currently generates about US$11 million in revenue from electric utilities in the United States.

Market Cap: US$4.2b

NuScale Power sits at the center of the small modular reactor theme, with the only NRC certified SMR design, a growing project pipeline in Romania and potential multi gigawatt deployment with TVA. The company is still loss making and has seen dilution and share price volatility, so investors are being compensated for accepting execution and funding risk. Investor interest is supported by the company’s reported liquidity of about US$1.9b, its partnerships across the fuel cycle, and analyst expectations for significant revenue expansion if projects move from planning to construction. For those looking at nuclear exposure that is still at the pre commercial phase, this stock may warrant closer examination beyond the headlines.

NuScale Power sits at the crossroads of certified SMR technology, reported US$1.9b liquidity and a still pre commercial business model that many investors may not have fully joined together. To see how that mix of execution risk and potential is framed in one place, go through the 1 key reward and 3 important warning signs (1 is major!)

Constellation Energy (CEG)

Overview: Constellation Energy is a large U.S. power producer that sells electricity, natural gas and energy solutions across multiple regions, anchored by a sizeable fleet of nuclear, wind, solar, gas and hydro assets totaling about 31,676 megawatts of capacity. It serves a wide mix of customers from utilities and municipalities to big corporates and households, with its nuclear-heavy profile positioned for buyers that want reliable, carbon free power.

Operations: Constellation Energy generates about US$31.3b of revenue from its Generation segment, with sales spread across the Midwest, Mid Atlantic, New York, ERCOT and other power regions.

Market Cap: US$95.6b

Constellation Energy is attracting attention because it sits at the intersection of long life nuclear assets, rising demand from data centers and corporates for 24/7 carbon free power, and a growing book of long dated contracts that can improve earnings visibility. Recent power purchase agreements with companies such as Microsoft, Meta and Walmart, plus the Calpine acquisition and nuclear uprates, point to capacity growth and higher quality cash flows. At the same time, heavy use of external funding, exposure to wholesale power markets and large, centralized plants leave the company sensitive to regulation, project delays and competition from distributed energy. That mix of strong fundamentals and real risks means the current set up at Constellation Energy is far from fully explained by headline earnings beats alone.

Constellation Energy’s growing book of long dated, nuclear backed contracts with tech giants hints at a story many investors may only see on the surface. The full risk reward picture sits inside the 4 key rewards and 2 important warning signs (1 is major!)

NANO Nuclear Energy (NNE)

Overview: NANO Nuclear Energy is a nuclear energy company developing a suite of compact reactors, including the KRONOS and LOKI microreactors for remote or power intensive sites, alongside ZEUS and ODIN designs and a planned high assay low enriched uranium fuel facility to support the wider reactor industry and related services.

Market Cap: US$1.0b

NANO Nuclear Energy sits at the high risk, high potential end of the Nuclear Energy Stocks screener, with no current revenue but a pipeline that spans microreactors, fuel processing and transport. Progress on the KRONOS prototype at the University of Illinois, recent AFWERX SBIR awards for U.S. Air Force use cases and index inclusion highlight growing institutional interest. A Q2 2026 net loss of US$9.18 million and past shareholder dilution underline the financial stretch of its plans. Forecast revenue growth is described as very large compared with the wider market, yet analysts still expect losses to continue. This puts more weight on how management uses its sizeable cash balance and handles licensing, manufacturing and fuel supply execution over the next few years.

Accelerating interest around NANO Nuclear Energy’s microreactor pipeline and cash position often skips the real question: How does that translate into future revenue and losses? The analyst forecasts for NANO Nuclear Energy hints at one twist many investors miss.
