Sprott Says Europe Leaned Harder on Russian Nuclear Fuel in 2025

Sprott Asset Management said in a new report that European reliance on Russian nuclear fuel increased during 2025, despite diversification efforts launched after Russia's invasion of Ukraine; the Sprott Uranium Miners ETF (URNM) traded at 58.19, up 7.66% on the day, as of 20:00 GMT on 21 August 2026.

Europe spent the years after Russia's invasion of Ukraine promising to get its nuclear power stations off Russian fuel. According to a new report from Sprott Asset Management, 2025 went the other way: European reliance on Russian nuclear fuel increased over the year, even as governments and utilities on the continent continued to talk about diversifying uranium supply.

The finding, reported by The Northern Miner, cuts against the political narrative that has surrounded the nuclear fuel cycle since February 2022. Coal, gas and oil flows from Russia were the subject of sanctions, price caps and pipeline politics. Nuclear fuel — a smaller trade in dollar terms but a far harder one to substitute — largely escaped that treatment, and the consequence is now visible in the numbers Sprott is putting in front of investors.

Why fuel is the hardest part of the nuclear chain to replace

Uranium does not go from mine to reactor in one step. It is mined and milled into concentrate, converted into uranium hexafluoride gas, enriched to raise the proportion of the fissile isotope, then fabricated into fuel assemblies that are specific to a given reactor design. Each stage is a separate industrial business with its own plants, its own long-dated contracts and its own permitting timelines.

That structure is why a country can buy uranium concentrate from Canada, Australia or Namibia and still be dependent on Russia. The bottleneck sits downstream, in conversion and enrichment capacity, where Rosatom's state-owned complex has for decades been the low-cost swing supplier to global utilities. Western conversion and enrichment expansions have been announced across North America and Europe, but capacity of that kind is measured in years of construction and commissioning, not quarters.

There is a further wrinkle in Europe specifically: a fleet of Soviet-designed VVER reactors, concentrated in central and eastern Europe, was built to run on Russian-fabricated fuel assemblies. Qualifying an alternative supplier for those reactors is a regulatory and engineering exercise, not a purchasing decision. Where that work is incomplete, the utility keeps buying from the incumbent.

The equity market's read on the same story

Investors treat structural tightness in the nuclear fuel chain as bullish for uranium producers, and that showed up on the tape the day the report circulated. The Sprott Uranium Miners ETF (URNM), which holds a basket of uranium mining and development equities, changed hands at 58.19 as of 20:00 GMT on 21 August 2026, up 7.66% on the day from a prior close of 54.05, and finishing near the top of a day range of 55.58 to 58.30. Note that the currency of quotation was not specified in the data feed used here.

That is an outsized move against a broadly firm but unremarkable equity tape. The S&P 500 proxy SPY was at $765.72, up 0.41%; the Nasdaq 100 proxy QQQ was at $713.44, up 0.35%; and the Dow 30 proxy DIA was at $532.22, up 0.89%. A uranium equity basket rising by roughly nineteen times the broad-market move is the market pricing something sector-specific rather than riding beta.

The physical vehicle told a quieter story. Sprott Physical Uranium Trust units (SRUUF) traded at 19.17, down 1.81% from a prior close of 19.52, with a day range of 19.11 to 19.73 — again in a currency the feed did not specify. The trust holds pounds of physical uranium rather than shares in the companies that mine it, so the divergence between the two is informative: on this day the buying was in the equities, in the operating leverage of producers and developers, rather than in the underlying commodity itself.

What Europe's dependence means for the supply build-out

The practical reading of Sprott's finding is that the Western fuel-cycle build-out is behind demand, not ahead of it. If diversification efforts had bitten, Russian share would have fallen in 2025. It rose. That implies either that replacement capacity is not yet in service at scale, or that where it exists, it is priced or contracted in a way that has not displaced the incumbent.

Several parties are directly affected:

• European utilities, which face the possibility that fuel supply becomes a sanctions target after they have already committed to reactor life extensions and new build.
• Western conversion and enrichment operators, whose expansion projects gain a stronger commercial case the longer the gap persists — but who need long-term utility contracts to underwrite the capital.
• Uranium miners and developers, particularly those with assets in allied jurisdictions, whose product carries a security-of-supply premium that has nothing to do with geology.
• Policymakers, who have to weigh the political cost of continued Russian purchases against the risk of taking megawatts off a grid already strained by electrification and data-centre load growth.

The signposts worth tracking from here

Three things will tell you whether 2026 breaks the pattern. First, whether any European sanctions package finally extends to enriched uranium products and fuel fabrication rather than stopping short of them. Second, whether Western enrichment expansions convert announced capacity into commissioned capacity, and whether utilities sign the multi-year offtake needed to justify the next tranche. Third, whether VVER operators complete the qualification work that lets alternative fabricators supply Soviet-design reactors at commercial scale.

Until at least two of those move, Sprott's observation is likely to keep describing reality. Europe can diversify where it buys its uranium ore comfortably enough. Diversifying the plants that turn ore into reactor fuel is the part that has not happened yet — and the equity market, judging by the day's move in the miners, has noticed.

Frequently asked questions

What did Sprott Asset Management actually report?

Sprott Asset Management said in a new report that European reliance on Russian nuclear fuel increased during 2025. That happened despite efforts across Europe to diversify uranium supply in the wake of Russia's invasion of Ukraine, according to reporting by The Northern Miner on the report's findings.

Why can't Europe just buy uranium from somewhere else?

Because uranium ore is only the first step. The concentrate must be converted into uranium hexafluoride, enriched, then fabricated into reactor-specific fuel assemblies. Russia's state nuclear complex has long dominated conversion and enrichment, and Western replacement plants take years to build and commission. Sourcing ore elsewhere does not remove that downstream dependence.

What are VVER reactors and why do they matter here?

VVER reactors are Soviet-designed pressurised water reactors operating in several central and eastern European countries. They were built to run on Russian-fabricated fuel assemblies. Switching to an alternative supplier requires engineering qualification and regulatory approval, so utilities operating them often continue buying Russian fuel until that work is finished.

How did uranium-linked funds trade on the day?

As of 20:00 GMT on 21 August 2026, the Sprott Uranium Miners ETF (URNM) traded at 58.19, up 7.66% from a prior close of 54.05. The Sprott Physical Uranium Trust (SRUUF) moved the other way, at 19.17, down 1.81% from 19.52. The data feed did not specify the currency of quotation.

Why did the miners rise while the physical trust fell?

The two vehicles hold different things. The ETF holds shares in uranium mining and development companies, which carry operating leverage to expected future prices. The physical trust holds pounds of uranium itself. On this day, buying concentrated in the equities rather than the underlying commodity, producing the divergence.

What would signal that Europe's dependence is finally falling?

Three markers: sanctions packages that explicitly cover enriched uranium and fuel fabrication rather than stopping short of them; Western enrichment and conversion expansions moving from announcement to commissioned capacity backed by long-term utility contracts; and completed qualification of non-Russian fuel assemblies for Soviet-design VVER reactors at commercial scale.
