ČEZ Extends Outage At Czech Republic’s Temelin-1, Cancels Maintenance At Temelin-2

17 Nov (NucNet): Czech utility ČEZ has decided to extend the annual outage for Unit 1 at the Temelín nuclear power station until mid-December 2016, because several operational checks took longer than initially expected, the company said in a statement. ČEZ said they have cancelled a turbine maintenance outage for Temelín-2, which had been planned for the same period. According to ČEZ, increased vibrations of the turbine at Temelín-2 occurred in recent weeks but operation is now stable and there is no reason for an outage. Unit 1 was shut down for refuelling and maintenance in August 2016. Unit-2 was restarted in October 2016 after an extended outage, which began in June 2016. ČEZ delayed the restart, because it needed to carry out checks on the turbine-bearing support and sealing system, which pushed back the restart schedule initially to late September and then to mid-October. The Temelín nuclear power station has two VVER-1000/320 pressurised water reactors.
