    Leibstadt and Beznau nuclear power plants can withstand infrequent severe earthquakes

    Both Leibstadt and Beznau nuclear power plants have shown that, in the event of or after a very severe earthquake, they can ensure that their reactors are stable and safe. Dose values of one or 100 millisievert which have to be complied with will not be exceeded even after earthquakes that are only to be…

    All Swiss nuclear power plants comply with the updated earthquake safety standards

    For the second time since the Fukushima accident in 2011, power plant operators have demonstrated that their plants are capable of withstanding an extremely rare, severe earthquake. The safety case for a flood caused by an earthquake has also been checked. The findings from the safety proofs generated in the aftermath of Fukushima have been…

    Quality assurance errors relating to some fuel rods in the Leibstadt Nuclear Power Plant

    A few days ago, Leibstadt Nuclear Power Plant (KKL) informed the Swiss Federal Nuclear Safety Inspectorate (ENSI) that some fuel elements do not fulfil the requirements of the applicable specifications. Accordingly, KKL decided to replace them for safety reasons. The safety of man and the environment was ensured at all times.

    “Cladding tube damage poses no risk to mankind or the environment”

    The Swiss Federal Nuclear Safety Inspectorate (ENSI) has issued Leibstadt Nuclear Power Plant (KKL) approval to restart subject to conditions. The conditions under which dryouts have occurred at KKL are known. KKL has instigated counter measures. Consequently operation is safe. In an interview Ralph Schulz, Director of the Safety Analyses Division, shares some background insights.

    ENSI issues Leibstadt Nuclear Power Plant approval to restart subject to conditions

    Leibstadt Nuclear Power Plant can restart power operation after an extended annual overhaul. The Swiss Federal Nuclear Safety Inspectorate (ENSI) has checked the clarification of the causes and measures derived from it for the avoidance of critical boiling conditions or dryouts. After the circumstances that led to the dryout had been identified, the supervisory authority…

    Findings on fuel elements in Leibstadt NPP: ENSI is classifying the incident as INES 1 and checking the submitted measures

    An inspection of fuel elements in Leibstadt NPP revealed that critical boiling states – so-called dryouts – had systematically occurred over several cycles. The Swiss Federal Nuclear Safety Inspectorate (ENSI) is classifying this incident as Level 1 on the International Nuclear and Radiological Event Scale (INES). It is currently checking the documents and actions submitted…
