After shutting Sizewell B down due to a potential issue with its lubrication system on Sunday, EDF resumed operation of the nuclear plant's two turbines Tuesday.
The short maintenance outage was a precautionary measure, according to Sizewell B director Jim Crawford.
“Safety is our over-riding priority. So, when the instruments indicated we could have a problem with the lubrication system, we took the conservative decision to take the station offline, while we fully investigated the problem and repaired any damage," Crawford said. "This was largely done as a precautionary measure, but we were able to take swift positive action and return the power station to service within 43 hours."
On Monday, EDF Energy also restarted its 450-megawatt unit 2 at Heysham 1 nuclear power plant on following a planned maintenance outage that began on March 1.
