The security of nuclear facilities and nuclear material is meant to prevent the compromise of nuclear safety through unauthorised actions, the intentional release of radioactive materials into the environment and the theft of nuclear materials. To this end, all Swiss nuclear power plants have a special security dispositive. As with safety, the principle of security is based on profound protection through structural, technical, organisatorial, personal and administrative measures.
The first review conference of the Amended Convention on the Physical Protection of Nuclear Material took place from 28 March to 1 April 2022. Switzerland lobbied for a repeated review of the implementation of the Amended Convention, to be carried out in five years time as part of an IAEA conference. The Amended Convention on […]
ENSI is part in a five-day International Atomic Energy Agency (IAEA) conference: The fourth “International Conference on Nuclear Security” (ICONS) will take place in Vienna from 20 to 24 May 2024, with Switzerland committed to a strong system of international security.
The conclusion of the experts from the International Atomic Energy Agency (IAEA) upon completion of the two-week review mission is that Switzerland has a robust nuclear security system. During the mission of the International Physical Protection Advisory Service IPPAS, from 30 October to 10 November 2023, the international team carried out a detailed examination of the national foundations and measures for the protection of nuclear installations, nuclear material and radioactive material against unauthorised intervention.

At the 62nd General Conference of the IAEA in Vienna, Switzerland last week committed itself to the strengthening of nuclear safety and security at the global level. ENSI also participated in bilateral discussions with international partners on the imortant topics of safety culture, emergency preparedness and the international security of nuclear installations and materials.
Swiss nuclear power plants have an adequate level of protection against a deliberate plane crash. This is confirmed by an update of the associated analyses ordered by the Swiss Federal Nuclear Safety Inspectorate (ENSI) in 2013. For security reasons, the details are being kept under wraps.
The nuclear security regime is well established in Switzerland. That was the finding of an IPPAS team of experts of the International Atomic Energy Authority (IAEA) at the conclusion of their two-week mission.
The reactor pressure vessel is enclosed by the containment as the third barrier. This consists of a steel primary containment and a concrete secondary containment.
With its pipelines, shut-off valves and other components, the cooling circuit, together with the reactor pressure vessel, is the second barrier for trapping radioactive substances
