Horizon Europe
Strengthening a European user facility for nuclear research
Expected Outcome:
the project results are expected to contribute to all of the following outcomes:
Scope:
ensuring access to EU and international research infrastructures is key to scientific progress in the nuclear field (including radiation protection, which is one of the foundation blocks of the European Research Area). Euratom support will be provided to cover the costs of transnational access for researchers or research teams from Member States and Associated States to EU and international state-of-the-art nuclear research infrastructures in other countries.
Users will be provided with access (at no cost to the researcher) to world-class nuclear research facilities; technical expertise from experienced scientists and engineers; and assistance with experiment design, assembly, safety analysis and examination.
The objective is to promote and enhance access to infrastructures that provide essential and unique services to the EU research community and are typically beyond the reach of individual laboratories. This will advance research in all the areas (except for fusion research, which is undertaken by the European Partnership in fusion research) covered in Annex I of the Council Regulation establishing the Euratom Programme.
The Commission encourages international cooperation with non-EU countries and international organisations within the scope of this action (partly in order to avoid any duplication with the OECD/NEA’s FIDES initiative), while encouraging investigating their complementarities. Support for researchers from non-EU stakeholders (including academia, research centres and industrial laboratories), non-EU countries and international organisations is envisaged where such access would be part of the promotion of international cooperation with the countries or international organisations concerned and researchers from Euratom Member States would have equivalent access to their infrastructures.
Based on the lessons learnt from former and current user facility projects, a framework and a set of common rules will be further improved for the future sustainable operation of a network of ‘Euratom User Facilities’. Dedicated support for the mobility of learners and/or linkage with the proposal submitted for topic HORIZON-EURATOM-2026-01-03 could be an advantage.
The active participation of major infrastructure operators will be required in order to achieve these objectives. The support scheme should operate through open calls and offer infrastructure access; technical expertise from experienced scientists and engineers; and assistance with experiment design, assembly, safety analysis and examination.
Proposals could pool the necessary financial resources from the participating national (or regional) research programmes with a view to implementing transnational proposals that result in grants to third parties to implement activities of this action.
The proposal should include an option for the JRC to use the future project’s operational environment (as a centralised platform supported by Euratom for facilitating the access to the JRC’s nuclear research infrastructures) for the implementation of the dedicated complementing coordination and support action between DG JRC and DG RTD on open access to the JRC’s nuclear infrastructures.
The page limit of the application is 40 pages.

Beneficiaries may provide financial support to third parties. The support to third parties can only be provided in the form of grants. Financial support provided by the participants to third parties is one of the primary activities of this action in order to be able to achieve its objectives. The maximum amount to be granted to each third party is EUR 300 000 for actions providing access to and securing availability of research infrastructures. This maximum amount is justified by the significant cost for providing key access to and securing the availability of unique research infrastructures.
Eligible costs may take form of unit costs for decision authorising the use of unit costs for the costs of providing trans-national and virtual access as defined in the corresponding Decision (unit-cost-decision-research-infrastructures_horizon-euratom_en.pdf (europa.eu)
General legal and financial set-up is described in General Annexes to the Euratom Work Programme 2026-2027, General Conditions, G — Legal and financial set-up of the grant agreements.
