...shutdown, the plant's owner CEZ said on Monday.
The unit was restarted and re-connected to the grip on Sunday morning, somewhat earlier than originally planned, after a regular test of regulatory systems, a Temelin spokesman said.
CEZ operates two 1,000-megawatt reactors at Temelin, which is near the Austrian border in the south of the country.
The Unit 2 was idle to allow for a regular fuel exchange.
Temelin is the biggest asset of state-owned CEZ, Europe's second largest power exporter after France's EDF . It accounts for 16 percent of CEZ's installed domestic capacity.
