The main aims of ENSI’s international cooperation are the global improvement of nuclear safety and security, and the strengthening of oversight in Switzerland. This is achieved through active participation in the international regulatory exchange of information and experience and through participation in international review missions.

ENSI monitors the development of international safety standards and foreign regulatory authorities, the latest state of the art of science and technology, and international operating experience. By doing so, it selectively influences the development of international regulations on nuclear safety and security. It participates in the further development of international safety standards with trend-setting requirements.

These are the most important areas of work within the framework of the international activities and cooperation of ENSI:

• the International Atomic Energy Agency IAEA,
• the OECD Nuclear Energy Agency OECD-NEA,
• the Western European Nuclear Regulators Association WENRA,
• the European Nuclear Safety Regulators Group ENSREG,
• the Heads of European Radiological Protection Competent Authorities HERCA,
• the European Association of Competent Authorities EURACA,
• the European Network on Operational Experience Feedback EU Clearinghouse,
• and the EU European Nuclear Security Regulators Association ENSRA.
