In the interest of its Treaty missions, ESA’s Statutes entrust it with a market observatory role. ESA has a duty to provide the Community with expertise, information and advice on any subject connected with the operation of the nuclear market.
To this end, ESA monitors the market in order to identify trends likely to affect the Union’s security of supply of nuclear materials and services. It aims to provide a wide range of information on nuclear market developments, as well as making reports on the EU market, average prices, total supply and demand etc. available to the public.
Through developing this web page, the Agency is seeking to inform market actors and observers about the current situation, market trends and, where appropriate, to highlight any possible shortcomings in the future.
The information refers, inter alia, to natural uranium price indices, including those calculated by ESA, to evaluations relating to the level of uranium supply and demand, and also to prominent events associated with the various stages of the nuclear fuel cycle in Europe and in the world.
Uranium EU Price: ESA Indices
Yearly Prices
ESA publishes on an annual basis three EU natural uranium price indices, based only on deliveries made to EU utilities or their procurement organisations under natural uranium and enriched uranium purchasing contracts in which the price is stated.
Since uranium is priced in different currencies, the fluctuation of the exchange rates influenced the level of the calculated price indices.
In order to establish a natural uranium price which excludes the conversion cost if the latter was not specified, ESA applied a rigorously calculated average conversion price, based on reported conversion prices and market information available.
In 2025:
- ESA spot U3O8 price: the weighted average of U3O8 prices paid by EU utilities for uranium delivered under spot contracts was calculated as:
EUR 168.92/kgU contained in U3O8 (28% increase from EUR 132.32/kgU contained in 2024)
USD 70.33/lb U3O8 (31% increase from USD 53.59/lb U₃O₈ in 2024)
- ESA multiannual U3O8 price: the weighted average of U3O8 prices paid by EU utilities for uranium delivered under multiannual contracts was calculated as:
EUR 131.37/kgU contained in U3O8 (8 % decrease from EUR 142.26/kgU in 2024)
USD 54.70/lb U3O8 (8% decrease from USD 59.18/lb U3O8 in 2024)
- ESA ‘MAC-3’ multiannual U3O8 price: the weighted average of U3O8 prices paid by EU utilities, only for multiannual contracts which were concluded or for which the pricing method was amended in the past three years and under which deliveries were made, was calculated as:
EUR 165.76/kgU contained in U3O8 (7 % increase from EUR 155.50/kgU in 2024)
USD 69.01/lb U3O8 (10% increase from USD 62.98/lb U3O8 in 2024)

Methodology
To calculate the quarterly average price (simple average), the original contract prices are converted, using the quarterly average exchange rate published by the European Central Bank, into EUR per kilogram of uranium in the chemical form U3O8.
To establish a price which excludes the conversion cost if it was not specified, ESA applies a calculated quarterly average conversion spot price indicator (based on conversion price indicators provided by consulting companies).
The date of signature by ESA is considered as the contract date.
In order to meet confidentiality rules, the indices are calculated only if there are three contracts with prices.
Uranium production and demand
In 2025, 1 795 tU of fresh fuel was loaded into commercial reactors. It was produced using 11 729 tU of natural uranium and 462 tU of reprocessed uranium as feed, enriched with 9 112 tSW.
The fuel loaded into EU reactors had an average enrichment assay of 4.15%, with 86% of such fuel falling between 3.59% and 4.726%. The average tails assay was 0.21%, with over 80% falling between 0.16% and 0.25%.
MOX (mixed oxide) fuel was used in several reactors in France and the Netherlands. MOX fuel loaded into nuclear power plants in the EU contained 8 200 kg of plutonium in 2025, 18% more than in 2024. The use of MOX resulted in estimated savings of 725 tU and 506 tSW, an increase of 20% from 2024 (see Annex 5). MOX fuel is produced by mixing plutonium recovered from spent fuel with depleted uranium obtained from the enrichment process. MOX fuel increases the availability of nuclear material, reduces the need for enrichment services and increases the security of supply.
The amount of natural uranium equivalent included in fuel loaded into reactors in 2025, including natural uranium feed, reprocessed uranium and estimated savings from MOX fuel, totalled 12 916 tU.
Supply of natural uranium
In 2025, demand for natural uranium in the EU accounted for approximately 20% of global uranium requirements. EU utilities purchased a total of 14 678 tU in 147 deliveries under multiannual and spot contracts.
As in previous years, supplies under multiannual contracts were the main source to meet demand in the EU. Deliveries of natural uranium to EU utilities under multiannual contracts accounted for 13 790 tU (of which 12 999 tU with reported prices). The remaining 889 tU was purchased under spot contracts.
On average, the quantity of natural uranium delivered was 104 tU per delivery under multiannual contracts.
Since the start of Russia’s war of aggression against Ukraine, EU utilities have been stockpiling nuclear materials and fuel to mitigate the risk of disruption to supply chains. Therefore, in 2025, they continued loading less material into reactors than they bought.
Origins of uranium
In 2025, natural uranium supplies to the EU continued to come from a variety of sources. The origin of natural uranium supplied to EU utilities remained similar to 2024, though there were some changes in market share.

Origins of uranium delivered to EU utilities in 2025 (% share) - Euratom Supply Agency
Natural uranium produced in Commonwealth of Independent States (CIS) countries accounted for 46.81% of all natural uranium delivered to EU utilities. CIS deliveries in 2025 amounted to 6 871 tU, compared with 5 825 tU in 2024. Natural uranium originating in non-CIS countries accounted for 7 807 tU, a decrease from 8 012 tU imported in 2024.
Conversion
Conversion
Conversion service deliveries to EU utilities were at the same level in 2025 as in 2024.
Under separate conversion contracts, 7 908 tU was converted, accounting for 60% of all service deliveries to EU utilities. The remaining 40%, or 5 340 tU, was delivered under other types of contract (purchases of natural UF6, EUP, bundled contracts for fuel assemblies).

Fabrication
The main fuel manufacturers are also reactor vendors, usually supplying the initial cores and early reloads for reactors of their own design. The largest fuel fabrication capacity can be found in the EU (Germany, Spain, France, Sweden and the United Kingdom), Russia and the United States.
The market is very competitive. As a result, a trend of continuously improving fuel design has emerged, focusing on enhanced burnups and improved performance.
Most EU utilities have access to at least two alternative fuel fabricators. In stark contrast with the situation elsewhere, the dependence on a single design and supplier of fuel for VVER reactors remains a significant vulnerability to the security of supply.
The Euratom Supply Agency notes the efforts by operators and producers to design, license, create fabrication capacity and contract alternative fuel for VVER reactors. Some countries dependent on VVER type reactors have made first steps to diversify the fuels and signed already contracts with alternative suppliers or are in negotiation process.
Inventories
At the end of 2025, the natural uranium equivalent in inventories owned by EU utilities totalled 42 522 tU. The inventories comprised uranium which was at different stages of the nuclear fuel cycle (natural uranium, in-process for conversion, enrichment, fuel fabrication and fresh fuel) and stored at EU or other nuclear facilities.
The changes in the aggregate natural uranium inventories do not necessarily reflect the difference between the total natural uranium equivalent loaded into reactors and uranium delivered to EU utilities. This is because the level of inventories is subject to movements of loaned material, sales of uranium to third parties and one-off national transfers of material.
Based on average annual EU gross uranium reactor requirements (11 835 tU per year), uranium inventories are sufficient to fuel EU utilities’ nuclear power reactors for more than three reloads on average. That average conceals a wide range, although all utilities keep a sufficient quantity of inventories for at least one reload.
A further analysis of EU utilities’ inventories shows that most are located in the EU. However, some are located outside the EU and a small fraction for future delivery is stored at unknown locations.
