Article 2 Definitions
For the purposes of this Regulation, the relevant definitions set out in Regulation (EU) 2021/695 apply. References in those definitions to the Union and Horizon Europe shall be construed as references to the European Atomic Energy Community (the ‘Community’) and the 2026-2027 Euratom Programme respectively. However, for the purposes of this Regulation, ‘work programme’ means the document adopted by the Commission for the implementation of the 2026-2027 Euratom Programme in accordance with Article 16 of this Regulation. All references in this Regulation to Regulation (EU) 2021/695 are to the version in force on 23 June 2025.
Article 3 Programme objectives
1. The general objective of the 2026-2027 Euratom Programme is to pursue research in the nuclear field and training activities, with an emphasis on the continuous improvement of nuclear safety, security and radiation protection, as well as to complement the achievement of Horizon Europe’s objectives, inter alia, in the context of the energy transition. 2. The 2026-2027 Euratom Programme has the following specific objectives: (a) to improve and support nuclear safety, security, safeguards, radiation protection, safe spent fuel and radioactive waste management and decommissioning, including the safe and secure use of nuclear power and of non-power applications of ionising radiation; (b) to maintain and further develop expertise and competence in the nuclear field within the Community; (c) to foster the development of fusion energy as a potential future energy source for electricity production and to contribute to the implementation of the European fusion roadmap; (d) to support the policy of the Union and its Member States on continuous improvement of nuclear safety, safeguards and security. 3. The objectives listed in paragraphs 1 and 2 shall be implemented in accordance with Annex I. The implementation of those objectives may, if duly justified, include responses to emerging opportunities, crises and threats.
Article 4 Budget
1. The financial envelope for the implementation of the 2026-2027 Euratom Programme for the period from 1 January 2026 to 31 December 2027 shall be EUR 598 346 804 in current prices. 2. The indicative distribution of the amount referred to in paragraph 1 shall be: (a) EUR 252 532 225 for indirect actions in fusion research and development; (b) EUR 115 339 356 for indirect actions in nuclear fission, safety and radiation protection; (c) EUR 230 475 223 for direct actions undertaken by the Joint Research Centre (the ‘JRC’). The Commission may not deviate from the amount referred to in the first subparagraph, point (c). 3. The amount referred to in paragraph 1 may also be used to cover expenses for preparation, monitoring, control, audit, evaluation and other activities and expenditures necessary for managing and implementing the 2026-2027 Euratom Programme, including all administrative expenditure, as well as evaluating the achievement of its objectives. The administrative expenses related to indirect actions shall not exceed 6 % of the amount distributed to indirect actions of the 2026-2027 Euratom Programme referred to in paragraph 2, first subparagraph, points (a) and (b). The amount referred to in paragraph 1 may also be used to cover: (a) in so far as they are related to the objectives of the 2026-2027 Euratom Programme, expenses relating to studies, meetings of experts, information and communication actions; (b) expenses linked to information technology networks focusing on information processing and exchange, including corporate information technology tools and other technical and administrative assistance needed in connection with the management of the 2026-2027 Euratom Programme. 4.
