Climate friendly powerhouse in southern Germany

In 1976, construction started on the two 1,344-MW units B and C at Gundremmingen near Günzburg in Bavaria. Following an eight-year construction period, the two units went on stream in 1984 and generated some 20 billion kWh of climate-friendly electricity annually. This made it an important pillar of the energy supply system in southern Germany and supplied around a quarter of the electricity generated in Bavaria overall before unit B was decommissioned. In line with the Atomic Energy Act, unit B was permanently decommissioned at the end of 2017. Unit B is being dismantled after receiving the decommissioning and dismantling permit on 20 March 2019 from the nuclear regulatory authority, the Bavarian environment ministry. Unit C will continue to produce electricity until the end of 2021. 

Interim storage facility and technology centre since 2006

In addition to units B and C, an interim storage facility is located at the site where spent fuel elements are kept in Castor containers. It was commissioned in 2006 and has space for up to 192 containers. The storage facility was taken over by the Gesellschaft für Zwischenlagerung mbH (BGZ – an organisation for interim storage) on 1 January 2019, in line with the law that reallocated responsibilities for nuclear disposal. In the same year the Gundremmingen Technology Centre in the former turbine house of the 250-megawatt unit Gundremmingen A (operational from 1966 to 1977) was approved by the Bavarian Ministry of the Environment. Here, components that are removed from the nuclear power plants owned by the shareholders (RWE Nuclear, PreussenElektra) can be dismantled, cleaned and prepared for disposal. 

Large number of jobs

More than 500 people are employed directly by Kernkraftwerk Gundremmingen GmbH. In addition, there are jobs at partner companies who work onsite on a permanent basis – as well as at suppliers and service providers in the region.
