Temelin nuclear power plant has stopped supplying power to the Czech grid as its second unit was disconnected on Thursday evening due to a pump defect.

The first unit was shut down at the end of June for a fuel replacement, Temelin spokesman Vaclav Brom told CTK today.
CEZ, Temelin’s operator, is to use alternative sources to ensure that power supplies and customers will not be affected by the outage, according to Brom.

The nuclear facility’s restart will be announced at the beginning of next week, while the first unit will be closed until the end of August.

Temelin experienced a similar problem in 2011, as Unit 2’s shutdown extended longer than planned while Unit 1 was forced into a fuel exchange, leaving the facility out of action for ten days. The problem was associated with the plant’s shift from American to Russian fuel.
