Ukraine has shut down a reactor at of its most powerful nuclear power plant for the second time in a month due to an apparent electrical malfunction.
Workers at the Zaporizhzhya power plant disconnected one of the facility's six reactors on December 28, citing a problem with the unit's generator.
Plant officials said the remaining five reactors are operating normally and that radiation in the area remains within acceptable limits.
A different reactor was shut down for several days earlier this month after experiencing a short circuit.
The 6,000-megawatt Zaporizhzhya facility is Europe's largest nuclear plant and the fifth-most-powerful in the world.
Its reactors were built according to a different design than those at the Chornobyl plant, the site of the world's worst nuclear accident in 1986.
