Germany shut down its last three power reactors on 15 April 2023. This marks the end of the era of commercial electricity generation from nuclear energy in Germany. However, a number of research reactors are still in operation. In this article, we explain why this is so, what distinguishes them from commercial reactors, and what the tasks of GRS are in this context.

From 27 to 29 November 2023, GRS will hold its annual AC2 user meeting at its Garching location. The main objective of the meeting is to provide a communicative platform for the exchange of experience between users.
For many years there have been reports of radioactive caesium-137 (Cs-137) that is sometimes detected in large quantities in mushrooms and wild boar, especially in regions of southern Germany. Just in time for the start of the mushroom season, there have again been more reports of this in recent weeks. Where does the substance come from and why is it still detectable in larger quantities in mushrooms and wild boar, while it is decreasing overall in the ecosystem?
In the "cold shutdown" state, as in the "hot shutdown" state, the reactor is subcritical, i.e. no nuclear fission takes place.

Currently, a total of 27 nuclear power plants and 6 research reactors are being decommissioned in Germany. But how does decommissioning actually work? What procedures are there? Who is involved and who is responsible? What are the challenges involved? The following dossier explores these questions.
