World’s oldest nuclear reactor to restart

Published on 06/03/2018

Reactor block 1 at Beznau nuclear power plant can restart after a three-year shutdown for repairs, the Swiss Federal Nuclear Safety Inspectorate said on Tuesday.

Built in 1969, the Beznau facility in canton Aargau is the world’s oldest commercial nuclear power plant. It has been out of service since March 2015, when anomalies were found in its steam generator.

The safety authorities now say the reactor presents no security risk.

Beznau is one of two reactors that were shut down to check the quality of steel components used in their steam generators. The Beznau II reactor was built in 1971.

Switzerland has five nuclear power reactors which generate about 34.5% of the nation’s energy needs. It uses nuclear energy to produce electricity, in research and medicine.

In May 2017, Swiss voters endorsed a new energy law that aims to promote renewable energy by banning new nuclear power plants and reducing energy consumption.

The Mühleberg nuclear plant near Bern, built in 1972, will shut down in 2019, according to the power station operators.
