Why Nuclear Energy Stocks to Buy Deserve Your Portfolio Attention Right Now

Global energy demand is surging, and nuclear power is increasingly recognized as the solution. With governments worldwide committing to triple nuclear capacity by 2050 and advanced technologies like small modular reactors creating new opportunities, the nuclear energy stocks to buy landscape has never been more compelling. Three companies stand out as prime candidates for investors seeking exposure to this expanding sector: Cameco, Centrus Energy, and Constellation Energy.

Cameco: Commanding the Uranium Value Chain

Cameco Corporation (NYSE: CCJ) operates as North America’s premier uranium and nuclear infrastructure provider, offering a comprehensive portfolio that spans mining, refining, enrichment, and reactor technology.

The company’s strength lies in its diversified asset base. Cameco controls significant uranium mining operations in Canada—a region known for high-grade deposits—while maintaining ownership stakes in Kazakhstani mines and mining rights in Australia. This geographic diversification insulates the company from regional supply disruptions.

Beyond mining, Cameco operates critical downstream infrastructure. The company runs a refinery and conversion facility in Ontario, transforming raw uranium concentrates into uranium trioxide, the purified intermediate form required for reactor fuel. This vertical integration creates competitive advantages and multiple revenue streams.

Perhaps most notably, Cameco owns 49% of Westinghouse, a leading nuclear reactor technology manufacturer and aftermarket service provider to commercial utilities. Westinghouse’s expertise in reactor design and ongoing maintenance creates a powerful synergy within the Cameco ecosystem.

This end-to-end presence throughout the uranium supply chain—from extraction to reactor design—positions Cameco as the clear choice for investors bullish on nuclear energy stocks to buy.

Centrus Energy: Positioning for Tomorrow’s Advanced Reactors

Centrus Energy (NYSEMKT: LEU) currently supplies the world’s nuclear reactors with low-enriched uranium (LEU), the fissile component in most commercial nuclear fuel globally. The company also provides enrichment and technical services to utilities and government agencies.

The company faces a critical inflection point. Centrus currently imports low-enriched uranium from global suppliers, including the Russian entity TENEX, under a waiver that expires in 2027. However, the Russian LEU ban will be fully phased in by 2028, forcing the industry to replace approximately 25% of previously imported enriched uranium supply.

This disruption creates opportunity. Centrus’s real competitive edge lies in its strategic pivot toward producing high-assay, low-enriched uranium (HALEU) using advanced centrifuge technology. Unlike conventional LEU, HALEU enables compact reactor cores, improved efficiency, longer refueling cycles, and greater design flexibility—making it the fuel of choice for tomorrow’s advanced nuclear reactors.

Centrus holds a unique position as the only HALEU producer licensed by the Nuclear Regulatory Commission for both commercial and national security applications. Scaling this production requires expanding capacity at its Piketon, Ohio facility, contingent on Department of Energy funding and long-term customer contracts. The company’s transformation from fuel procurer to advanced fuel producer represents significant long-term upside for nuclear energy stocks to buy.

Constellation Energy: Capitalizing on Hyperscaler Demand

Constellation Energy (NASDAQ: CEG) dominates U.S. nuclear power generation with the nation’s largest nuclear fleet, commanding 22 gigawatts of capacity. The company’s operational excellence is evident: its reactors achieved a 94.6% capacity factor in recent years, surpassing industry benchmarks and translating to superior revenue per reactor.

Constellation’s geographic reach enhances its appeal. The company operates across critical U.S. electricity markets, including the western PJM region (serving 65+ million people across 13 states) and the MISO region spanning the Midwest, Plains, and Southern territories. Its recent $27 billion acquisition of Calpine expanded western exposure and positioning in California’s high-demand market.

What makes Constellation particularly attractive is its success in securing long-term power purchase agreements with technology giants. Microsoft locked in a 20-year PPA with Constellation and is funding the restart of Three Mile Island Unit 1 (now the Crane Clean Energy Center). Meta Platforms similarly committed to a 20-year PPA for power from Constellation’s Clinton Clean Energy facility in Illinois.

These hyperscaler agreements signal a structural shift: major tech companies now recognize nuclear energy as essential to meeting AI data center power demands while maintaining carbon-neutral operations. Constellation’s diversified nuclear portfolio positions it as the primary beneficiary of this trend among nuclear energy stocks to buy.

The Investment Thesis: Why Nuclear Stocks Matter Now

The convergence of rising global energy demand, political support for nuclear expansion, and technology company commitments creates a rare window of opportunity. Nuclear provides reliable, carbon-free baseload power around the clock—meeting both energy demand and climate objectives simultaneously.

For investors considering nuclear energy stocks to buy in 2026, these three companies offer distinct but complementary exposure: Cameco commands supply chain advantages, Centrus captures advanced fuel upside, and Constellation benefits directly from hyperscaler demand. Each addresses critical elements of the expanding nuclear ecosystem, making them worthy additions to growth-oriented portfolios.
