Leibstadt nuclear power plant, review of structural safety of Zent active storage facility

Project overview

Several large components of the power plant need to be exchanged in order to ensure the safe operation of the Leibstadt nuclear power plant, combined with an increase in efficiency levels for the coming decades. The new Zent active storage facility was built for the long-term storage (decay storage) of these large elements being removed.
