Swiss Federal Nuclear Safety Inspectorate ENSI
Part 1: Transfer from HSK to ENSI = Independence
of the swiss regulatory authority
ENSI
Kernkraftwerk Leibstadt
IAEA Meeting TWG-NPPCI – Vienna 20. – 22.05.2009
Slide 20
Initial situation before transfer HSK to ENSI (not independent from SFOE)
Reporting structure

The HSK is the regulatory authority of the Swiss Confederation with
responsibility for nuclear safety

Administratively, it currently reports to the SFOE (Swiss Federal Office of
Energy)

SFOE is responsible, therefore, for both the use of nuclear energy and
protection from it
Independence

Potential conflicts of interest require the institutional separation of use and
protection functions

Formal separation is called for in both the international Convention on
Nuclear Safety and the Swiss Nuclear Energy Act

Slide 21
Principal aspects of ENSI
Act on the Swiss Federal Nuclear Safety Inspectorate
• Final approval on 22.06.07 by the Parliament
Legal structure
• Institution of public law with its own legal personality
• Functionally, institutionally and financially independent
Supervision
• Supervised by federal council
• ENSI reports annually about activity and finances
Duties
• Supervisory authority for nuclear safety (as hitherto)
• Supervisory authority for physical protection (new)
