Legal Basis

The assessment and monitoring of nuclear plants are based on laws, guidelines and underlying technical and scientific documentation, which transparently set out the safety requirements and criteria that ENSI applies for its assessments.


Links to Federal Acts and Ordinances

ENSI’s organisation is governed by the Swiss Federal Nuclear Safety Inspectorate Act (ENSI Act, ENSIG).


Most of the legislative bases for ENSI’s supervisory activities are laid down in the Swiss Federal Nuclear Energy Act (NEA/KEG) and the Swiss Federal Law on Radiological Protection (LRaP/StSG).
