Unit 5 of the Kozloduy Nuclear Power Plant was brought back on stream at 2:04 hrs local time on Sunday, the N-plant told BTA.

The reason for disconnecting the reactor on September 1 has been established: a short circuit in the electric section of the reactor. The necessary repair activities have been carried out.

As at 11:00 hrs on Sunday the unit's power was 520 megawatts and it will keep on increasing by 2 per cent per hour in compliance with the schedule of the Central Dispatcher's Department in Sofia.

After unit 5 renewed its operation, the sixth reactor is expected to be disconnected from the power grid for scheduled renovation at about 14:00 hrs on Sunday.
