Location of nuclear reactors in Switzerland = commercial reactors = decommissioned reactors = research / test reactors = planned / discarded reactors

The list of nuclear reactors in Switzerland includes all nuclear power plants that are in operation or whose planning has finally been abandoned, as well as all research reactors , all of which with one exception are now decommissioned.

Overview

In Switzerland there are three nuclear power plants with four reactor blocks and an installed gross total output of 3,095 MW on the grid. Their share in total electricity generation is around 37 percent.

In Switzerland, the Beznau 1 reactor block , which is still in operation, was the first to go into operation on July 17, 1969. Beznau 1 is thus (2019) the oldest active nuclear reactor in the world. The Leibstadt nuclear power plant , with one reactor block and an installed gross output of 1,220 MW, is the most powerful, with the reactor block also being the newest.

After the nuclear disaster in Fukushima , the government in Bern decided on May 25, 2011 to phase out nuclear energy. The National Council approved the motion on June 8, 2011 , and the Council of States followed suit on September 28, 2011. The existing Nuclear Energy Act is to be changed so that no permits are issued for new nuclear reactors, the existing plants are to be shut down after a total term of 50 years . The nuclear phase-out would thus be completed by 2034. However, the legislative proposal of the Council of States expressly does not speak of a “technology ban”; the Federal Council should report regularly on the further development of the technology.
