Decommissioning projects in Germany:

Overview of the Plants

Every decommissioning project is unique. The choice of decommissioning strategy and project schedule depend to a large extent on the type of facility, operation history and other framework conditions such as financing.

  • Power reactors and uranium enrichment and fuel fabrication facilities are commercial plants and belong to the power utilities and companies operating in this sector. The companies pay for the decommissioning of these installations.
  • Research reactors, prototype reactors for power generation and prototype nuclear fuel cycle facilities are generally based at research centres or universities, and their decommissioning is publicly funded for the most part.
  • The decommissioning of Greifswald and Rheinsberg nuclear power plants in eastern Germany, formerly the German Democratic Republic, is funded from the federal budget.


This map provides an overview of the installations that are being decommissioned in Germany or which have been dismantled completely. 

Facilities which have been permanently shut down but have not yet been granted decommissioning licences are not shown.

Decommissioning by facility type

Power and prototype reactors

Three nuclear reactors have been fully dismantled:

  • Niederaichbach nuclear power plant (KKN)
  • Grosswelzheim superheated steam reactor (HDR)
  • Kahl experimental nuclear power plant (VAK). 

The first two are prototype reactors, whose development was not pursued.

Kahl experimental nuclear power plant was the first nuclear power plant built in Germany. After more than 25 years of operation, it was permanently shut down in 1985. Components and buildings were decontaminated and fully dismantled, and the site was released from regulatory control under nuclear and radiation protection law.

Experience has shown that the decommissioning of a power or prototype reactor takes at least 10 to 20 years.

Research reactors

Decommissioning of research reactors is based on the same principles as nuclear power plant decommissioning. The decontamination, disassembly and waste conditioning techniques used are very similar. However, the facility size and the radioactive inventory are significantly smaller in the case of a research reactor compared to a nuclear power plant. 

As research reactors are smaller, technical dismantling often takes less time than is the case with larger power reactors.

Nuclear fuel cycle facilities

At Hanau, several fuel element fabrication plants were shut down, dismantled and released from regulatory control under nuclear and radiation protection law in the 1980s and 1990s. The former Karlsruhe Nuclear Research Center (now Karlsruhe Institute of Technology (KIT) Campus North) ran Karlsruhe Pilot Reprocessing Plant (WAK) from 1971 to 1990. Dismantling this facility poses particularly complex challenges. In 2009 and 2010, the high-level liquid waste (HLLW) produced during the plant’s operation was conditioned by vitrification in a new purpose-built facility on the WAK site. This Karlsruhe Vitrification Facility (VEK) was later shut down and is part of the WAK decommissioning project. 

The operator plans to have fully completed the dismantling of the facility (including VEK) by the end of the 2020s.

A key difference to dismantling nuclear power plants is that nuclear fuel cycle facilities are in some cases heavily contaminated with alpha-emitting radionuclides from mechanical and chemical processing of nuclear fuel during operation. Different decontamination and dismantling techniques and a different radiation protection regime for workers are therefore required.
