According to ENSI 2020, nuclear facilities were safe
The Swiss Federal Nuclear Safety Inspectorate (ENSI) takes stock of the year 2020. According to this, the number of incidents reported in Swiss nuclear facilities was slightly below the average of previous years. In addition, the pandemic had no impact on operations and audits.
In an initial assessment, ENSI announced that the nuclear power plants (NPP) in Switzerland were “safely operated” in the past year of supervision. The number of reportable incidents in 2020 was slightly below the average of previous years, according to a media release . Despite the pandemic situation, ENSI was present in the NPPs. All systems would have complied with the safety requirements.
Since pandemic plans were already in place before the coronavirus occurred, the operators were prepared for the current situation. Annual major revisions have been adapted to it. ENSI is convinced that you have nevertheless complied with the legal requirements.
The Mühleberg NPP has been shut down for good since September 15, 2020. The decommissioning of the research reactor at the University of Basel has now been completed to the point that no more reportable incidents can occur.
Most of these incidents, eight in total, concerned the Beznau NPP . On December 7th, both reactor blocks were shut down after an inspection required by ENSI and restarted on December 21st. Further clarifications on one aspect are still ongoing.
