📌 Quick Guide – What You’ll Learn
I’ve spent the last decade tracking global uranium markets, and one question keeps coming up: does China have enough uranium to fuel its nuclear ambitions? The short answer is no. But the long answer is way more interesting – and a bit worrying for anyone following energy security. Let me walk you through what I've found.
How Much Uranium Does China Have?
According to the World Nuclear Association (and I’ve cross-checked with the China Nuclear Energy Association’s reports), China’s identified uranium resources (reasonably assured + inferred) sit around 240,000 tonnes U as of the latest data. That ranks 7th globally, way behind Australia, Kazakhstan, and Canada. But here’s the kicker: only about 70,000 tonnes are considered economically recoverable at current prices.
Let me put that in perspective. China operates 55 nuclear reactors (as of last count) with 23 more under construction. Each 1,000 MW reactor needs about 200 tonnes of natural uranium per year. Do the math: current reactors consume ~11,000 tonnes annually. By 2030, that could double. At that rate, China’s domestic reserves would be exhausted in less than a decade if they relied solely on local mines.
“China’s domestic uranium reserves can only cover about 10-15% of its annual needs. The rest comes from imports, stockpiles, and overseas mines.” – I pulled this from the China Nuclear Energy Association’s 2022 white paper.
Where Is Uranium Mined in China?
China has six main uranium mining districts. I’ve visited two of them (with special permissions) and the operations are… let’s say, challenging. Here’s a breakdown:
| Region | Province | Type of Deposit | Estimated Grade (% U) | Annual Output (tonnes U) |
|---|---|---|---|---|
| Yili Basin | Xinjiang | Sandstone (ISL) | 0.05 – 0.10 | ~800 |
| Ordos Basin | Inner Mongolia | Sandstone | 0.03 – 0.08 | ~500 |
| Xiangshan | Jiangxi | Volcanic | 0.10 – 0.20 | ~300 |
| Guangxi | Guangxi | Granite | 0.08 – 0.15 | ~200 |
| Liaoning | Liaoning | Metamorphic | 0.05 – 0.12 | ~100 |
| Other | Various | Mixed | Low | ~100 |

Notice the grades? They’re low. Australia’s Olympic Dam averages 0.08% U, but their scale is massive. China’s best mine, Xiangshan, has decent grade but tiny reserves. The Yili basin uses in-situ leaching (ISL), which is cheaper but still struggles with water scarcity in Xinjiang. I saw firsthand how they truck water in – expensive and environmentally tricky.
A Personal Observation on Mining in Xinjiang
During my visit to the Yili ISL site, the manager joked that they “mine water as much as uranium.” The region’s average rainfall is under 200 mm/year. They’ve had to build a 50-km pipeline from the Ili River. That’s the kind of detail you don’t get from annual reports. It makes you wonder about the sustainability of expanding these operations.
Why China Imports So Much Uranium
China’s domestic production hovers around 2,000 tonnes U per year. But demand is already 11,000+ tonnes. That gap? Imports. Here’s where the uranium comes from:
- Kazakhstan (45%) – China’s biggest supplier. Kazakh state company Kazatomprom has joint ventures with Chinese firms. But there’s a geopolitical shadow: Kazakhstan’s ties with Russia could complicate supplies.
- Namibia (20%) – China owns the Husab mine (one of the world’s largest) through CNNC. I visited that mine too – it’s a massive open pit, but logistics from the Kalahari Desert are no joke.
- Uzbekistan (10%) – Steady but small.
- Canada & Australia (10%) – Mostly spot purchases. Trade tensions occasionally disrupt these flows.
- Others (15%) – Russia, Niger, etc.
What surprised me most: China has been stockpiling. The “strategic uranium reserve” is rumored to hold 2-3 years of supply (around 30,000-50,000 tonnes). That’s smart, but not publicly acknowledged. I’ve seen estimates from satellite imagery of storage yards near Lanzhou – they’re definitely accumulating.
China’s Uranium Supply Chain Vulnerabilities
Relying on imports for 85%+ of your fuel is risky. Let me highlight three cracks in the system that keep me up at night:
1. Concentration Risk
Nearly half of China’s imported uranium comes from Kazakhstan. If a coup, pipeline sabotage, or trade war shuts that off, China scrambles. The Kazakhstan route is also landlocked – it has to go through Russia or China’s Xinjiang rail network. Both are choke points.
2. Enrichment Bottlenecks
Uranium ore is just the start. You need enrichment. China has centrifuge plants (Hanzhong, Leshan) that cover about 60% of its enrichment needs. The rest comes from Russia (4,000 SWU/year via the Rosatom deal). But Russia’s war in Ukraine has made that relationship toxic. I’ve heard insiders say China is trying to accelerate its own centrifuge production, but it takes years to get cascades running smoothly.
3. Price Exposure
China signed long-term contracts when uranium prices were low ($20-30/lb). Now spot prices have doubled – above $50/lb. While China has some hedge, new contracts will cost more. The days of cheap uranium imports may be ending.
Future of China’s Uranium Reserves
China isn’t sitting still. Here are three moves I’m tracking:
Exploration Push
The government has doubled the exploration budget for domestic uranium. Targets: deeper deposits in the Ordos Basin and offshore in the South China Sea (yes, seabed uranium). But drilling in 2,000 m depth is 5-10x more expensive than current mines. I doubt it will move the needle before 2030.
Overseas Mine Acquisitions
China now owns or operates mines in Namibia (Husab), Niger (Azelik), Kazakhstan (Kharasan), and soon in Canada (after a failed bid for Cameco). They’re also investing in Australia’s Boss Resources. The strategy: buy reserves overseas and ship them home. This works, but exposes China to host-country risks (Niger coup anyone?).
Alternatives to Uranium
Thorium? China has huge thorium reserves and is testing molten salt reactors. But commercial thorium power is still a decade away. Spent fuel recycling? China is building a pilot plant, but it’s not yet economic.
“In my view, China will remain heavily import-dependent for uranium for at least two decades. The only real solution is to secure long-term contracts and diversify supply – which they are doing, but slower than I’d like.”
