Neutron source BER II - shutdown in December 2019
The end of an era
After 40 years of successful neutron research in Berlin-Wannsee, the research reactor BER II was finally shut down at the end of 2019. The shutdown was decided by the HZB Supervisory Board in summer 2013.
In Europe, there are now several neutron sources that offer a higher neutron flux than BER II. Furthermore, the European neutron spallation source (ESS) is currently being built in Sweden, where researchers will one day be able to use even more intensive neutron radiation for their experiments – and where the neutrons will be produced entirely without nuclear fission.
In the next two decades the research reactor will be dismantled. How interested citizens can become involved in the dismantling process and can contribute to the ongoing dialogue regarding the project, you can find out on our pages concerning the shutdown and dismantling of the Berlin experimental reactor BER II.
