Uranium is Going Nuclear ☢️

Ōkuma is a small Japanese town that faces the vast Pacific. With fishing boats, rice paddies, and a population of just over eleven thousand, it is the kind of place the world had never really bothered to notice.

For the better part of a century, it was a coal country. But by the late 1950s, the coal was running out. The town needed a replacement. So, in October 1961, the council voted unanimously to invite the Tokyo Electric Power Company to build a nuclear plant on its doorstep. They called it the Fukushima Daiichi. The sea was always visible from the turbine halls.

It was that same sea that, on 11 March 2011, forced the whole world to notice Fukushima. 

At 2:46 that afternoon, a magnitude‑9.0 earthquake — one of the strongest ever recorded in Japan — shook the Tōhoku coast for six minutes.

The quake triggered a massive tsunami, sending walls of water racing toward the Fukushima coastline. Waves driven by the surge smashed into the town, overtopped the sea wall, and drowned the diesel generators, cutting power to the reactor’s cooling systems. Within days, three reactor cores had melted, hydrogen blasts blew apart reactor buildings, and radioactive material spilled into the air, soil, and sea. 

The Fukushima disaster became the worst nuclear accident the world had seen since Chernobyl.

Nuclear energy and uranium that powered it never quite recovered from Fukushima. New nuclear projects around the world were canceled, countries announced phase‑outs, and in the world of energy, “nuclear” became a word you used silently, and uranium prices dropped to record lows. 

Nearly 15 years later, the world wants to fall back in love with nuclear, and uranium prices are showing it. Uranium spot prices touched $86 per pound in early 2026, up nearly 30% year-over-year, and the highest levels since the mid-2000s uranium boom.

But experts say the uranium market is entering a structural deficit cycle that could worsen over the next decade. In short, when the world seems to now love uranium, there's not much left. So what’s causing the uranium deficit, and why has the world suddenly turned back to nuclear energy?

To understand why uranium is suddenly back in demand — and why supply is struggling to keep up — we need to go back to the world’s long, uneasy relationship with nuclear power. So, let’s begin there. 

America's relationship with nuclear energy didn't begin with vision. It began with war.

The Manhattan Project cost $2 billion, consumed three years, and put 130,000 people to work. By the time it was done, the United States had built something more than a weapon — it had built an industrial machine. Engineers, physicists, enrichment plants, and a well-oiled supply chain. When Japan surrendered in August 1945, Washington was left holding all of that infrastructure and no obvious place to point it.

The answer came quickly. In 1946, President Truman signed the Atomic Energy Act, pulling all nuclear technology under federal civilian control through the newly created Atomic Energy Commission. Then, in 1953, Eisenhower walked into the United Nations General Assembly and reframed the entire conversation. "The United States knows that peaceful power from atomic energy is no dream of the future," he told the world. The atom, he argued, did not have to mean weapons. It could mean electricity — abundant, peaceful, and available to the world.

Congress followed the next year with the Atomic Energy Act of 1954, the legislation that opened the door for private industry. For the first time, American companies could own and operate reactors.

But every reactor needs fuel. And that fuel was uranium.

The AEC moved fast. It began guaranteeing minimum purchase prices for uranium ore, and overnight the economics changed completely — the price a miner could fetch jumped nearly tenfold. Prospectors flooded the Colorado Plateau, that vast stretch of high desert spanning Colorado, Utah, New Mexico, and Arizona, and soon spread into Wyoming, Texas, Washington State, and the Dakotas. America's uranium rush had begun.

At the peak, in 1980, the United States was producing 43.7 million pounds of uranium per year — the highest output ever recorded — with more than 250 active mines operating simultaneously. The United States was the world's leading uranium producer from the 1950s to the 1970s, a nearly three-decade dominance built on government policies and guaranteed prices. 

And then a valve in Pennsylvania stuck, and it all came apart.

On March 28, 1979, a cooling malfunction at Unit 2 of the Three Mile Island Nuclear plant in Pennsylvania triggered a partial meltdown — the worst nuclear accident in American history. There was no casualty; in fact, the radiation release was minor. But the psychological damage was huge.

Public confidence in nuclear energy collapsed almost overnight. Regulators piled on new safety requirements. Construction timelines stretched, and costs ballooned.  What’s worse, dozens of reactors already planned or mid-construction were quietly canceled.

The numbers tell the story. 

According to the World Nuclear Association, in 1980, the United States had over 250 active uranium mines. By 1984, that number had fallen to just 50. Production cratered from 16,800 tonnes of uranium to 5,700 tonnes in the same period. The boom towns of Wyoming emptied out. The Colorado Plateau went quiet. Uranium prices dropped from $40 per pound to $10 per pound. 

The rest of the world, meanwhile, kept building. 

Canada had been quietly developing high-grade deposits in Saskatchewan. Australia sat atop massive reserves, including the Olympic Dam deposit, one of the largest known uranium deposits on the planet. And the Soviet Union had spent decades building an enormous nuclear industrial complex.

By the late 1980s, the global uranium market had flipped. Through the 1970s, primary mine production had broadly kept pace with reactor demand. But by 1991, that relationship quietly reversed — reactors were consuming more uranium than the world's mines were producing. The gap should have triggered a price spike and a new mining boom. It didn't, because of what happened next. 

In December 1991, the Soviet Union collapsed. When it did, it left behind the largest stockpile of nuclear weapons ever assembled — tens of thousands of warheads and enormous reserves of highly enriched uranium.

Suddenly, the world had a new kind of uranium supply, not from mines, but from dismantled bombs.

In 1993, Washington and Moscow signed an agreement known as Megatons to Megawatts. The deal was simple: Russia would take weapons-grade uranium from dismantled Soviet warheads, dilute it into low-enriched uranium suitable for nuclear reactors, and sell it to the United States as fuel.

Over the next twenty years, the program dismantled the equivalent of 20,000 nuclear warheads. The uranium extracted from them powered roughly 10% of U.S. electricity for two decades.

And in doing so, it completely reshaped the uranium market.

Every year, about 24 million pounds of uranium equivalent flowed into the market from dismantled weapons — nearly half of global reactor demand at the time. Utilities had no incentive to sign long-term mining contracts when a steady stream of cheap secondary supply was available.

Mining companies couldn’t compete with Russian uranium. Throughout the 1990s and early 2000s, uranium mines shut down worldwide. Exploration budgets disappeared. The industry shrank. The uranium market had quietly become one without mines. By the 2000s, the consequences of that strange arrangement were beginning to surface.

In the 2000s, global nuclear reactors required roughly 170 million pounds of uranium every year, but the world’s mines produced only 90 to 100 million pounds. The rest came from what the industry called secondary supplies — dismantled nuclear weapons, government stockpiles, reprocessed fuel, and uranium extracted through enrichment adjustments.

The world was so busy exhausting its stockpiles that it forgot a simple reality: it was consuming far more uranium than it was digging out of the ground.

Eventually, the math began to catch up.

In 2003, uranium prices had been languishing near $10 per pound for almost a decade. But as inventories tightened and demand from nuclear reactors remained steady, the market began to stir.

Then came a shock.

In 2006, flooding struck the Cigar Lake mine in Saskatchewan, one of the largest and highest-grade undeveloped uranium deposits on earth. Construction at the mine was delayed indefinitely, removing what many utilities had expected to be a major future source of supply. Almost overnight, fears spread across the uranium market that new production would not arrive in time.

At the same moment, another shift was taking place on the demand side.

China and India — two of the world’s fastest-growing economies — were beginning to plan massive nuclear power expansions. Governments and energy planners started talking about a possible “nuclear renaissance,” a new era in which atomic power would help meet rising electricity demand while reducing carbon emissions.

This classic low supply and high demand scenario began to reflect in the uranium prices. In June 2007, uranium spot prices hit $135 per pound — up from $7 at the start of the decade. It was the fastest price run in the commodity's history.

Exploration companies multiplied almost overnight. Investors flooded into uranium mining stocks. Prospectors returned to old deposits across Canada, Australia, Africa, and Central Asia, hoping to cash in on the new rush.

And then Fukushima happened. 

Countries soon began announcing reactor closures and nuclear phase-outs. Japan shut down all 54 of its operating reactors — plants that had supplied roughly 30% of the country’s electricity. Meanwhile, countries like Germany, Switzerland, Belgium, and South Korea froze nuclear expansion plans.

This drastically affected the uranium market. That’s because almost all uranium that is mined ends up in nuclear reactors. Nearly 99% of global uranium demand comes from nuclear power generation, leaving the metal with very few alternative uses.

So when reactors shut down, uranium demand disappears just as quickly. Prices slid steadily downward, eventually falling below $20 per pound by 2016 — a level at which most uranium mines in the world could no longer operate profitably. At those prices, there was little incentive to build new mines or even keep existing ones running.

For nearly a decade, the nuclear sector operated in survival mode. But around 2020, the conversation began to change.

The planet was getting warmer. Year after year, global temperatures were breaking records, and scientists increasingly pointed to rising carbon emissions as the driver behind climate change. Governments around the world began committing to net-zero carbon targets, pledging to eliminate or offset their greenhouse-gas emissions, 

Enter nuclear power. 

Unlike wind or solar, nuclear reactors produce enormous amounts of electricity continuously while emitting virtually no carbon. They also require remarkably little land. According to the Nuclear Energy Institute, a 1,000-megawatt nuclear power plant occupies roughly 1.3 square miles. Producing the same amount of electricity using renewable sources would require far more space. Solar installations would need around 31 times more land, while wind farms would require about 173 times more to generate the same level of output.

To meet their net-zero carbon goals, countries worldwide began announcing the resurrection of nuclear power. 

Just as nuclear power was re-entering the energy conversation, another force emerged that would dramatically increase electricity demand: Artificial intelligence.

Training large AI models and running hyperscale data centers requires enormous amounts of electricity — sometimes as much power as a small city. The companies building this infrastructure suddenly faced a problem: they needed vast quantities of reliable, round-the-clock energy. Big Tech turned to nuclear power. 

Microsoft was among the first to make a decisive move. In 2024, the company signed a 20-year agreement with Constellation Energy to help restart Unit 1 of the Three Mile Island nuclear plant in Pennsylvania, a reactor that had been shut down in 2019. The project aims to bring the plant back online by 2028, supplying hundreds of megawatts of reliable electricity to support Microsoft’s rapidly expanding network of AI data centers.

Google soon followed with a different approach. The company partnered with advanced reactor developer Kairos Power to deploy a fleet of small modular reactors (SMRs)

Amazon has taken an even more direct investment route. Through its climate and energy initiatives, the company invested $500 million in the SMR developer X-energy, while also partnering with Energy Northwest to build four small modular reactors in Washington state.

Meta has also begun positioning itself in the nuclear ecosystem. The company signed a 20-year contract with Constellation Energy to secure nuclear electricity while simultaneously exploring partnerships with advanced reactor developers TerraPower and Oklo. 

Now, Washington is taking the nuclear route as well.

The shift began in May 2025, when President Donald Trump signed a set of executive orders designed to overhaul the regulatory framework that had made building nuclear reactors in the United States painfully slow and expensive. 

At the center of the effort was the Nuclear Regulatory Commission (NRC), the federal body responsible for licensing reactors. The administration directed the agency to complete license reviews within 18 months and cut its review fees in half.

The administration also invoked the Defense Production Act, formally designating the nuclear fuel supply chain as a matter of national security. Federal agencies were instructed to identify government land suitable for reactor construction, while the White House laid out an ambitious target: ten large reactors breaking ground by 2030.

Additionally, in a partnership with Westinghouse Electric, which is owned by Cameco and Brookfield Asset Management, the U.S. government announced plans to facilitate financing and permitting for at least $80 billion in new nuclear reactors. 

The mission is clear: Washington wants to quadruple America’s nuclear capacity, from roughly 100 gigawatts today to nearly 400 gigawatts by 2050. 

More nuclear reactors naturally point to one thing: more uranium. The question now confronting the energy industry is simple: Does the world actually have enough uranium to support this nuclear comeback?

Many analysts believe the answer is a resounding NO.

We are already in a structural uranium deficit that will only widen past 2030 — a gap that could reach 196 million pounds by 2040 if reactor buildout accelerates. But how did we get here? The story is one of decades of underinvestment, deliberate production cuts, and a market that ran on borrowed stockpiles until it couldn't. 

Through the 2010s, uranium prices languished below $30 per pound for years. That wasn't enough to incentivize new mines.

Even the mines that existed weren't running full out. Kazakhstan's state-owned Kazatomprom — the world's largest uranium producer, accounting for 43% of global output — spent seven years voluntarily cutting production by 20% below its licensed capacity to stabilize prices. In 2023, it produced 20.5-21.5 kilotonnes (53-56 million pounds) instead of its full potential.

Canada did the same: Cameco suspended its McArthur River mine — the highest-grade uranium deposit on the planet — in 2018 because $20 per pound didn't cover costs. It only restarted in 2022, and even then at partial capacity.

The deficit didn't crash the market because secondary sources covered it. In 2025, those sources — utility inventories, enrichment underfeeding, recycled material, and government stockpiles — supplied roughly 30-40 million pounds, or 14-20% of total demand. That's now changing. Those stockpiles are finite and declining; their contribution is projected to fall to just 4% by 2050.

So why not just build more mines? Because it isn't fast. 

The process from discovery to first production will take anywhere between 10 and 20 years. Yet global uranium requirements for nuclear reactors are expected to rise sharply in the coming decades. According to the World Nuclear Association, reactor demand is projected to increase by about a third to roughly 86,000 tonnes by 2030, and nearly double to around 150,000 tonnes by 2040.

Interestingly, it is not just the United States that is on a nuclear path; other countries are also racing to get their hands on uranium. 

China is already moving aggressively in that direction. The country currently operates 59 nuclear reactors with about 62 gigawatts of capacity, while 28 additional reactors (roughly 30 GW) are under construction and 27 more are planned. Beijing aims to reach around 70 GW of nuclear capacity by 2025, expand that to about 200 GW by 2035, and have nuclear power supply roughly 10% of the country’s electricity by then.

China’s domestic uranium production covers only a fraction of its needs, so Beijing has increasingly turned outward to secure supplies. State-owned nuclear companies such as China National Nuclear Corporation (CNNC) have signed long-term supply agreements with Kazatomprom, Kazakhstan’s state uranium producer. At the same time, China has been expanding its footprint across Africa, securing stakes and offtake agreements in uranium projects in Namibia, Niger, and Zimbabwe.

India is also moving to secure its uranium supply as it expands its nuclear power program. In February 2026, Kazakhstan agreed to supply fresh uranium to India under a new contract with Kazatomprom, continuing a long-standing partnership between the two countries. 

The following month, in March 2026, India signed a $2.6 billion uranium supply agreement with Canada’s Cameco, covering about 22 million pounds of uranium between 2027 and 2035. The deal is designed to help fuel India’s 22 operating reactors while supporting future reactor expansion, including advanced reactor technologies

After decades of underinvestment, nuclear energy — and the uranium that powers it — is stepping back into the global spotlight.

For years, the industry quietly shrank. Mines closed, exploration dried up, and prices stayed too low to justify new supply. But the world has changed.

Reactors are being restarted, new ones are planned, and the electricity appetite of artificial intelligence is only adding to the pressure. Analysts now warn that the uranium market is entering a structural deficit that could deepen well into the next decade. In other words, uranium prices may be about to go nuclear.
