The categories overlap, so the fund’s index rules and dated holdings—not its name—show what you are buying exposure to.
What separates a uranium ETF from a nuclear energy ETF?
The main distinction is where a fund reaches along the nuclear-energy value chain. A uranium-focused strategy generally centers on finding, developing, mining, processing, or otherwise supporting uranium supply. A broader nuclear-energy strategy may include those businesses but also power generators, reactor and facility contractors, and companies selling equipment or services to the industry.

Those business models can face different influences. Miners and developers have more direct exposure to uranium-industry conditions; utilities earn from electricity generation; suppliers and engineering firms depend on projects, equipment demand, and services. This is a way to understand the businesses represented, not a guarantee of how any ETF will respond to uranium prices, power markets, regulation, or construction activity.
Compare the funds by their rules and holdings
| Fund | Stated approach | What the available holdings evidence shows |
|---|---|---|
| Global X Uranium ETF (URA) | Global X describes exposure to companies involved in uranium mining and nuclear-component production, including extraction, refining, exploration, and equipment manufacturing. Its benchmark is the Solactive Global Uranium & Nuclear Components Total Return Index. Global X fund page | Its equity-sector breakdown dated August 31, 2026 was 60.7% Energy, 26.5% Industrials, 6.2% Utilities, 5.7% Materials, and 0.9% Information Technology. These are sector allocations, not percentages of uranium producers; Global X says the breakdown excludes cash and other holdings. Global X sector breakdown |
| Sprott Uranium Miners ETF (URNM) | The April 30, 2026 summary prospectus says URNM seeks to track generally the VettaFi Global Uranium Mining Index. Under normal circumstances, it invests at least 80% of total assets in index securities and at least 80% of net assets plus investment borrowings in securities of Uranium Mining Companies. The index can include miners, exploration and development companies, physical uranium holders, royalty owners, and non-mining companies supporting mining. SEC-filed summary prospectus Prospectus index definition | The cited prospectus gives strategy rules, but no dated top-holdings list is provided here. |
| VanEck Uranium and Nuclear ETF (NLR) | Its index covers companies involved in uranium mining; construction, engineering, or maintenance of nuclear facilities and reactors; nuclear electricity production; or equipment, technology, and services for the nuclear power industry. VanEck fund page | VanEck’s holdings page accessed October 4, 2026 displayed utilities and power producers, uranium companies, and suppliers or technology firms, including Constellation Energy, Cameco, Public Service Enterprise Group, Fortum, BWX Technologies, NexGen Energy, China General Nuclear Power, Oklo, Kazatomprom, and X-Energy. VanEck notes holdings may vary. VanEck holdings |
| iShares Nuclear Energy and Uranium Mining UCITS ETF (NUUR) | BlackRock’s June 2026 factsheet describes a UK-marketed, Irish-domiciled UCITS fund that aims to reflect the STOXX Global Nuclear Energy and Uranium Mining Index. BlackRock factsheet | The factsheet reported 41 holdings and listed Cameco, Dominion Energy, Duke Energy, Constellation Energy, Kansai Electric Power, GE Vernova, IHI, Siemens Energy, Talen Energy, and Siemens among its top ten as of June 30, 2026. The list demonstrates a mix that includes utilities and power companies as well as uranium exposure. BlackRock factsheet |
Why fund labels can mislead
URA is a clear example of overlap: despite “Uranium” in its name, its stated mandate includes nuclear-component producers, and its benchmark includes nuclear components. NLR explicitly combines miners with power producers and industry suppliers. URNM is more tightly defined around uranium mining companies, but even its index definition allows certain physical uranium holders, royalty owners, and supporting businesses. “Uranium ETF” therefore does not necessarily mean miners only, and “nuclear energy ETF” does not necessarily mean utilities only.

- Index and investment rules: Identify which activities qualify and whether the prospectus specifies minimum investment thresholds, as URNM does.
- Business mix: Distinguish miners and developers from utilities, engineering companies, component makers, and service or technology businesses.
- Holdings date and concentration: Compare holdings from the same date where possible. A holdings page is a snapshot, and VanEck explicitly cautions that its securities and holdings may vary.
- Geography, domicile, and trading currency: A global portfolio may hold businesses in several markets. Check the issuer’s current geographic breakdown and the listing’s trading currency; NUUR is an Irish-domiciled UCITS fund marketed in the UK.
- Costs and turnover: Use each fund’s latest prospectus or factsheet rather than assuming one fund’s figures apply to a category.
Fees and turnover: figures that apply to URNM
Sprott Funds Trust’s April 30, 2026 URNM summary prospectus lists total annual operating expenses of 0.75%. It also reports portfolio turnover of 35% for the fiscal year ended December 31, 2025. Both figures are specific to URNM and their stated disclosures; they are not averages for uranium or nuclear ETFs. URNM expense and turnover disclosures
How to read sector and performance claims
Sector labels are not a substitute for underlying company research. URA’s 60.7% Energy allocation, for example, is a sector classification, not evidence that 60.7% of the fund is uranium producers. Similarly, a nuclear-power statistic does not describe an ETF’s holdings or returns. Global X, citing the U.S. Office of Nuclear Energy in March 2021, notes that nuclear plants can achieve “nearly 92%” maximum power output; that is context about nuclear power, not an ETF metric.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which exposure fits the question you are asking?
If the question is specifically about businesses tied to uranium supply, start with the index and mandate language around mining, exploration, development, and production. If you want exposure to the wider nuclear-power ecosystem, check whether the fund also owns electricity generators, reactor contractors, equipment makers, or technology and service companies. Then verify the latest holdings and fund documents: a broad label alone cannot tell you the exact mix or how concentrated it is.
