LONDON--EDF Energy said Monday it would shut down three of its nuclear reactors in the U.K. to carry out inspections following the shutting down of another of its reactors earlier this summer.
The utility in June said it had shut down one of two nuclear reactors at its Heysham 1 nuclear power station to allow for investigations into one of its eight boiler units.
Whilst routine inspections at its other nuclear reactors had not found similar defects, EDF said it taken the "conservative decision" to shut down its second reactor at Heysham and two further reactors at its Hartlepool station to carry out further checks. The other reactors are of similar design to the one EDF has already shut down.
The company said its investigations into the reactors would take around eight weeks. It said the first reactor at Heysham remains shut down as further checks had confirmed a problem with the equipment's boiler spine: when the reactor returns to service it is likely to be operated on a reduced load until a suitable repair strategy can be found, EDF said.
