GUARDIANS: Europe’s flagship project to address nuclear crises
Paris, October 2025 – The European Union has launched GUARDIANS, a strategic project under the Horizon Europe – Cluster 3 “Disaster-Resilient Societies” programme (Grant Agreement number 101225744). Its objective is to strengthen Member States’ ability to anticipate, manage, and mitigate the consequences of a nuclear crisis. Coordinated by the CEA, this four-year project (2025–2029) will develop an integrated decision-support platform, GUARDNET for public authorities and frontline responders to improve the response organisations at different level (local, national and international).
In a context marked by the risks of reactor accidents, large-scale contamination, and geopolitical tensions affecting nuclear infrastructures, GUARDIANS brings together an unprecedented combination of:
▪ innovative and cost-effective Nuclear and Radiological detection technologies, robotics, medical triage tools, and protective measures,
▪ crisis-management methodologies and societal studies,
▪ table-top and field exercises. (Link -PDF)
