Temelin - Czech nuclear power plant Temelin stopped supplying power to the grid as the second unit was unhooked over a pump defect on Thursday evening and the first unit was shut down at the end of June due to a fuel replacement, Temelin spokesman Vaclav Brom told CTK today.
CEZ, Temelin's operator, will use other sources to ensure power supplies. Customers will not be affected by the outage, Brom said.
The energy control authority has been informed about the shutdown of the second unit that will take a few days, Brom said.
A date of Temelin´s restart will be announced at the beginning of next week, he added.
The first unit will be closed until the end of August. All activities related to the fuel exchange and modernisation of the turbine proceed in line with the schedule. The reactor´s pressure vessel will be examined next week.
The modernisation will raise the unit´s output from the current 1,056 MWe to 1,078 MWe (electric output in megawatts) maintaining fuel consumption at the current levels, said Brom.
This is not for the first time that both units of Temelin are out of operation. In 2011, the second unit´s shutdown was longer than planned and the first unit had to undergo a fuel exchange. Temelin was closed for ten days. The problems were caused by the plant´s shift from American to Russian fuel.
Temelin launched power supplies in December 2000. With an output of 2 x 1,056 MWe, it is the largest electricity source in the Czech Republic covering one-fifth of the country´s consumption.
Last year, the nuclear plant produced 15.065 billion kWh of electricity.
