Unplanned Events & Incidents
Unit 6 at the Zaporozhye nuclear power station in Ukraine has been reconnected to the grid after the correction of a fault that led to its shutdown on 28 December 2014, operator Energoatom said.
The Russian VVER V-320 unit is operating at 40 percent power and the cause of the incident is being investigated, Energoatom said. The company said the unit was disconnected from the grid to avoid damage to the turbine. The incident has been provisionally rated as Level 0 on the International Atomic Energy Agency’s International Nuclear and Radiological Events Scale. This means it was a “deviation of no safety significance”. Earlier this month Zaporozhye-3 shut down automatically as the result of an electrical control component failure.
