An annual emergency exercise, overseen by ENSI, takes place in all nuclear power plants, the Paul Scherrer Institute and in Zwilag. The nuclear installations use these exercises to optimise their own organisation, processes and the installation. ENSI also systematically assesses its own deployments and, based on this, improves the ENSI emergency response organisation.

Every two years, FOCP performs a general emergency exercise, in which, among other things, the cooperation of the emergency response organisation of the nuclear power plant with external emergency preparedness partners, especially with those at a cantonal and federal level, is checked.

FOCP compiles a report on the general emergency exercise with the feedback and assessments of all participants. The results are incorporated in the optimisation of the emergency response organisation of all participating bodies.
