Ukraine’s nuclear plant operator Energoatom has disconnected unit 3 of Zaporizhzhya nuclear power plant (NPP) from the grid to protect against inner generator damages.
Contrary to the concerns, radioactive consequences have not been recorded from the incident that occurred on 28 November 2014.
Damage was caused to the coil connecting the house load transformer and unit transformer breakers, affecting the capacity of power delivery.
Repairs for the unit are underway, and it is expected to be in operation by 5 December 2014.
Ukraine Energy and Coal Industry Minister Volodymyr Demchyshyn said: "Actually, there is no threat at the Zaporizhia nuclear power plant.
"There was an electrical short circuit in the system of energy delivery late last week, thus, only one unit, unit number 3, is out of order at the nuclear power plant. There is no threat to the reactor. This is technical damage which is being eliminated.
"The block is in a state of repair."
Located in the south-east part of Ukraine in Enerhodar, the Zaporizhzhya NPP is the largest nuclear power plant in Europe and the fifth-largest worldwide.
Equipped with six VVER-1000 pressurised light water nuclear reactors, the plant has a combined power output of 6,000MW, which accounts for 50% of electricity from nuclear power and more than 20% of total power supply in Ukraine.
