Swiss nuclear reactors

Two recent national referendums have determined the fate of nuclear power in Switzerland. In 2016, a programme for the accelerated phase-out of the five nuclear reactors was rejected. In May 2017, the adoption of phase one of the Energy Strategy 2050 allows the existing reactors to be operated till the end of their serviceable life, but no new reactors may be built.

Switzerland has 4 nuclear power plants, and 5 operating reactors. The total electrical capacity is 3,372 GW, which in 2017 covered about 36% of electricity needs.

Mühleberg

Mühleberg, Canton Bern. 1972 operational. Boiling water reactor (BWR). 373 MW gross output, 3.0 TWh per year. It will decommissioned on the 20th December 2019.

Beznau I

Döttingen, Canton Aargau. 1969 operational (making it the oldest operational nuclear power station in the world).

Pressure water reactor. 380 MW gross output. 5 GWh electrical power and 1.7 TWh district heating per year. It has been offline since 2015 due to structural problems, and currently no definitive plan for decommissioning or returning it to operation has been made.

Beznau II

Döttingen, Canton Aargau. 1971 operational. Pressure water reactor. 380 MW gross output, 5 TWh electrical power and 1.7 TWh district heating per year. Offline in 2016, in 2017 it is operational.
