Swiss nuclear power station shut down, due to a technical problem

Technical problem shuts down Swiss nuclear power station, SwissInfoCh, 29 Dec 19, The Leibstadt nuclear power station in northern Switzerland has been disconnected from the power grid and shut down because of a technical fault.

Once the cause has been clarified, the plant will be put back into operation as soon as possible, the operator said. It is not clear when that will be. ……

Transducers replaced 

Two reactor shutdowns had already occurred at Leibstadt in April and May 2019. Both had the same cause. According to ENSI a malfunctioning transducer led to incorrect values in a channel of the main steam pressure measuring system. These triggered a rapid closure of the turbine inlet valves.

……Saturday’s shutdown comes a week after the 47-year-old Mühleberg nuclear power plant near Bern was permanently switched off. It was the first Swiss nuclear power reactor to be decommissioned. https://www.swissinfo.ch/eng/leibstadt_technical-problem-shuts-down-swiss-nuclear-power-station/45461886
