SOFIA (Reuters) - Bulgarian nuclear power plant Kozloduy has shut down one of its two 1,000 megawatt (MW) units after a protection system was activated at the unit's generator, a plant spokeswoman said.

The plant's other 1,000 MW unit is working at full capacity, the operator said in a statement, adding that there is no danger of any radioactive contamination.
