Nuclear Stocks are Making a Comeback. Here’s My Favorite Way to Play It

New technologies are making nuclear energy much safer and more efficient than before. And nuclear stocks are benefitting.


Overlooked in the popular discussion of renewable energy is nuclear power. It’s understandable: just as the sector rallied 50% out of the Great Recession on an emerging consensus that nuclear generation could meet future electricity needs without adding to climate change, the Great East Japan Earthquake occurred. One of the most powerful earthquakes ever recorded, it caused a tsunami which led to the Fukushima reactor melting down. In response, countries including Japan and France pledged to eliminate their reliance on nuclear power. Nuclear stocks gave up the ghost too, dropping by half in the following months—and out of the renewable energy conversation.

Ten years later nuclear is still not top-of-mind when people think about solving global warming. But the smart money has been moving into the sector as safety and technological advances mean a new era is coming for nuclear power – one of smaller, more powerful, safer plants. As the accompanying monthly chart of the VanEck Uranium and Nuclear Energy ETF (NLR) shows, the sector is now trading near new highs.

Nuclear stocks are breaking out to new highs.

The fundamental reason is the long-term trend toward decarbonization. Nuclear energy can play a vital part since it remains the most compact way to deliver massive amounts of electrical power. In the short term, however, Russia’s aggression in Ukraine is causing much of Europe to reconsider the role of nuclear energy. Germany, in particular, is facing pressure to delay the planned mothballing of its three remaining nuclear power facilities.

Nuclear already produces 10% of the world’s electricity (20% in the U.S.). Japan and France have reversed their post-disaster plans to cut back and, earlier this month, the International Energy Agency outlined a 10-point plan to reduce EU reliance on Russian fossil fuels, including maximizing nuclear output. And, to be clear, the industry has implemented many safety measures in response to Fukushima to avoid the cascade of problems that led to that failure.


As chief analyst of Cabot’s Sector Xpress Greentech Advisor, I’ve had nuclear in my sights all along. And I’m currently recommending a nuclear stock to my subscribers that’s up 40% since mid-September. I’ll tell you what it is, but first let me explain the market development that really has me excited.

A New Kind of Reactor

It’s HALEU. That’s an acronym for high-assay low-enriched uranium. It allows for smaller and more efficient reactors. It’s seen as the future of the industry, both for new reactors and for extending the life of existing reactors.

Right now, commercial nuclear reactors use low-enriched uranium, in which less than 5% of the uranium mass is the U-235 isotope that generates energy. On the other end of the spectrum is highly enriched uranium, where up to 90% of the uranium is the U-235 isotope. It’s used by U.S. Navy ships and subs, as well as some research reactors.

HALEU is in between, with 5% to 19.75% of the uranium mass that power-source isotope. As an added bonus, HALEU can be made from down-blending the used, military-grade uranium. The U.S. Department of Energy (DOE) is so excited by HALEU that it’s close to approving a new generation of reactor designs it says “will completely change the way we think about the nuclear industry.” Power plants will be smaller, more efficient, produce less waste uranium and they won’t need their cores replaced for 20 years, unlike every 18 to 24 months for current reactors. At the moment, the DOE is in the process of deciding on the next generation reactor from 10 finalists; nine of them are designed to use HALEU.

The first market for HALEU will be micro-reactors for the military. The Pentagon is seeking to remove domestic bases from the wider electrical grid as part of its climate change-related plans to keep bases operational under increased extreme weather events. A Defense Department prototype reactor, Pele, should be available by 2024. Perhaps 130 reactors will be deployed. By mid-decade, utility owned micro-reactors will start rolling out for remote locations like interior Alaska and far-flung islands. They’ll generate perhaps 10 megawatts (MW) of energy with a one-time upfront fueling to last 20 years. More powerful, advanced utility reactors could come to market by 2030. Even current reactors will be able to use HALEU in place of the low-enriched stuff.

What has me especially excited about this development is, by rule, the U.S. military needs to find a domestic supplier of HALEU to fuel those Pele reactors. Plus, the federal government wants to re-shore uranium refining. Political winds can change, but both recent Republican-led administrations and the Biden administration call HALEU an issue of national energy security. The government is even exploring a strategic uranium supply.

My Favorite Nuclear Stock Today

Right now only one company will be able to meet American needs: Centrus Energy (LEU). An Ohio company, Centrus is building the only U.S. facility that will be licensed to produce the high-assay uranium. The federal government is paying the bulk of the cost of the initial facility under a contract, which later can be expanded modularly to meet demand. Centrus already produces low-enriched uranium, and generates $245 million a year in sales to U.S., European and Asian utility customers.

But HALEU is where the growth will come from: Based on a survey the Nuclear Energy Institute conducted of U.S. advanced reactor developers, it is possible the market for HALEU could be worth $1.2 billion annually by 2030 and $5.6 billion by 2035, based on the low-end price of HALEU (in Europe) today. Centrus has non-binding agreements to produce HALEU for reactors planned by private businesses to come on line by the end of the decade.

And LEU shares are up 98% in just the last year! The company has no net debt and a forward price-to-earnings ratio of just 15 even after the huge run-up in the last week.
