The sixth block of Kozloduy NPP stopped working accidentally in 1:50 PM when one of the generators of the electrical protection was triggered.
Later that day it returned to its normal function. The Energy system operator data showed that during the day the fifth block of the NPP was the only one put in action. The electricity usually produced by the sixth block was compensated by a fuel-burning power plant. Kozloduy NPP gave no details about what brought the electrical protection to action but later that day all the causes were eliminated.
