At the end of this year, the last nuclear power plants in Germany are to be shut down, which the former federal government decided within a few months after the reactor accident in Fukushima in 2011.
But the nuclear age is far from over.
The fuel rods from the reactors will continue to radiate radioactively for hundreds of thousands of years.
Where is this garbage supposed to be stored for so long?
This has been the subject of debate in Germany for almost half a century.
And in all likelihood it will take another three decades before a repository goes into operation - if at all.
A message from Sweden makes you sit up and take notice.
The government there has just decided: The national nuclear waste repository is to be built in Östhammar, a municipality with around 20,000 inhabitants on the Baltic Sea coast, in ten years the first fuel rods could be stored there.
Finland is one step further.
On the Olkiluoto peninsula in the southwest of the country, construction work for the repository is already well advanced, and it is scheduled to go into operation in 2024.
Apart from a few mysterious sites in the former Soviet Union, it will be the world's first nuclear waste repository.
Unlike in Germany, the nuclear power plants in Sweden and Finland are to remain connected to the grid for a few more decades.
But the explosive question of final storage has already been clarified there.
