In Switzerland, on-going activities regarding safety assessment of the different stages in the lifetime of nuclear installations consist of periodic assessments and assessments of long-term operation for existing Swiss NPPs.

When it comes to international affairs, Switzerland has signed the Convention on Nuclear Safety (CNS) on 31 October 1995. In November 2011, an IRRS Mission was conducted in Switzerland. The results of the mission are currently being implemented, and it is planned to have an IRRS Follow-Up Mission in 2015. In October 2012, an OSART Mission to the Mühleberg NPP was completed. Switzerland participated in the European Stress Test and its Follow-Up activities.
