How is the programme designed to deliver results?


ITER is being constructed in Saint Paul-Lèz-Durance (France) to prove the scientific and technological feasibility of fusion as a future source of sustainable energy, which would be a major contribution to the EU’s long-term goal of decarbonising the energy system.

The risk, costs, and long-term nature of a large research project such as ITER puts it beyond the reach of individual EU Member States, and calls for action at the EU level and beyond. A global framework has been established between seven international partners (Euratom, Russia, China, India, Japan, South Korea, and the USA) representing more than half of the world’s population to support ITER’s construction, which started in 2007. Euratom provides about 45% of all components through the European Joint Undertaking for ITER and the development of Fusion Energy (Fusion for Energy, F4E).


The general objective of the ITER-related EU action in the 2021-2027 MFF is to fully support the continuation of ITER’s construction to reach the first experimental operations by 2027 and to continue further installations and upgrades laying grounds for successful full power operation by 2035.

Europe's support to ITER and to other activities related to ITER, such as the Broader Approach activities with Japan, contributes to the strategic agenda of the European Union for clean and secure energy. ITER is stimulating the European industrial investment in new advanced technologies for the components of the facility and in advanced civil engineering for its construction.


The EU participation to ITER pursues four specific objectives:

  • Secure continued EU leadership in the ITER project by ensuring timely delivery of EU components and active participation in ITER governance processes;
  • Provide sufficient performance-based funding to ITER International Organisation for its operations, particularly the assembly of the installation from the components arriving from individual ITER members;
  • Offer European high-tech industries and SMEs a valuable opportunity to innovate and develop ‘spin off’ products for exploitation outside fusion;
  • Continue activities with Japan (Broader Approach) on the operation of the satellite tokamak JT60SA and on the development of a full scale material testing facility (IFMIF/DONES) to ensure that all technical and scientific elements needed for the design of a fusion-based power generation device for demonstration are in place.

The programme covers the European contribution to the ITER International Organisation in cash and in-kind for the construction of the ITER facility, which includes the procurement of equipment, installation, general technical and administrative support for the construction phase as well as the participation in commissioning and operations.

The programme also covers other ITER-‑related activities, such as the Broader Approach activities with Japan.

These contributions are delivered through Fusion for Energy (F4E), the European Domestic Agency, located in Barcelona (Spain).

Where are we in the implementation?

You will find information on the programme implementation in this webpage.

It will be updated when the programme will have started on an annual basis alongside the publication of the draft budget and the discharge.

Next publication (estimation): June 2022.

Predecessor programmes 2014-2020

The programme is a continuation of its MFF 2014‑2020 predecessor. The budget of the programme has almost doubled.
