In this article, we are going to discuss the best nuclear power stocks to buy now.

The United States of America is the largest producer of nuclear power in the world, accounting for almost 30% share of the global generation of nuclear electricity. The sector has witnessed an accelerated investor interest over the last year, largely driven by a continued focus on the goal to achieve net-zero carbon emissions and the widespread recognition of nuclear’s importance in the global ‘clean energy transition’. The International Energy Agency recently revealed that nuclear is set to generate a record level of electricity in 2025. There are more than 70 gigawatts of new nuclear capacity under construction around the world, one of the highest levels in the last 30 years, and more than 40 countries have plans to expand nuclear power’s role in their energy systems.

One of the largest modern growth drivers of nuclear energy is SMRs, or small modular reactors, that have a power capacity of up to 300 MW(e) per unit and are quicker to build with greater scope for cost reductions. The IEA estimates that with the right support, SMR installations could reach 80 GW by 2040, accounting for 10% of the overall nuclear capacity globally. Several major US corporations are now actively working to develop the technology in the country, offering a potentially more flexible and cost-effective approach to nuclear power generation.

Another major accelerator for the industry is the ongoing AI boom and the accompanying data centers, which could consume as much as 9% of all energy generated in the US by 2030. This energy needs to come from a relatively cheap, clean, and reliable source where nuclear has massive potential. Several American tech giants are already investing billions of dollars in nuclear power and SMRs as an emissions-free source of electricity for their AI and other businesses. On the sidelines of the CERAWeek conference in Houston earlier this month, several major companies have even signed a pledge to support the goal of at least tripling the world’s nuclear energy capacity by 2050.

That said, a large number of nuclear energy stocks have lost momentum over the last year, primarily due to a steep fall in the prices of uranium. From highs of more than $105 per pound at the start of 2025, uranium prices have plunged to just over $63 currently. The decline of over 26% is influenced by factors such as the winding up of the Kazakh-based ANU, Trump tariff uncertainties, and geopolitical tensions with Russia, which account for around 44% of the global uranium enrichment capacity.

The United States imports the lion’s share of its uranium from Canada and President Trump’s 10% tariffs on energy imports from the northern neighbor could significantly hamper the growth of the nuclear sector. A Canadian uranium miner and producer stated last month that prices for US customers could jump by 10% if Trump’s tariff threats were to be implemented, raising costs for a sector that is looking to explode over the coming decade.

With that said, here are the Best Nuclear Energy Stocks to Invest in.

Denison Mines Corp. (NYSEAMERICAN:DNN) is in for a big win from Wheeler River, which is to become one of the largest, untouched uranium mining areas in the world. The crown jewel of the project is the high-grade Phoenix uranium deposit, where DNN had already achieved a total engineering completion of approximately 65% at the end of 2024.
