Kiev: Ukraine on Sunday shut down one of the six reactors in its most powerful nuclear power plant for the second time in a month due to an apparent electrical malfunction.
The Zaporizhia Nuclear Power Plant said on its website that radiation levels in the area remained normal and that the station`s other five reactors continued to operate without any problems.
It said the plant`s sixth reactor was "disconnected from the grid by the generator`s internal defence mechanism" early Sunday.
A short circuit in the same plant`s third reactor contributed to power shortages in Ukraine at the start of the month.
The Zaporizhia station, in the southeast of the country, is Europe`s largest and fifth-most powerful in the world.
It generates 40 percent of Ukraine`s nuclear power and switched on its first reactor in 1984.
