Article 10 — Cumulative, alternative and combined funding

1. The 2026-2027 Euratom Programme shall be implemented in synergy with Horizon Europe and with other Union programmes. 2. In order to achieve the objectives of the 2026-2027 Euratom Programme and to address challenges common to the 2026-2027 Euratom Programme and to Horizon Europe, activities cutting across the objectives set out in the 2026-2027 Euratom Programme or those implementing Horizon Europe, or both, may benefit from the Community financial contribution, subject to Article 9. In particular, the 2026-2027 Euratom Programme may provide a financial contribution to the Marie Skłodowska-Curie Actions in order to support activities relevant for nuclear research. 3. An action that has received a contribution from another Union programme may also receive a contribution under the 2026-2027 Euratom Programme, provided that the contributions do not cover the same costs. The rules of the relevant programme shall apply to the corresponding contribution to the action. The cumulative funding shall not exceed the total eligible costs of the action. The support from the different programmes may be calculated on a pro-rata basis in accordance with the documents setting out the conditions for support. 4. Actions may receive support from the European Regional Development Fund or the European Social Fund Plus in accordance with the relevant provisions of Regulation (EU) 2021/1060 where they have been awarded a Seal of Excellence label under the 2026-2027 Euratom Programme by virtue of complying with the following cumulative conditions: (a) they have been assessed in a call for proposals under the 2026-2027 Euratom Programme; (b) they comply with the minimum quality requirements of that call for proposals; (c) they may not be financed under that call for proposals due to budgetary constraints.
