Chernobyl plant still without external power supply - Ukraine nuclear body

LVIV, Ukraine - Ukraine's state nuclear power regulator said on Friday the electricity supply to the Chernobyl nuclear power station had not yet been restored, despite Russia's energy ministry saying it was restored by Belarusian specialists on Thursday.

Ukraine has warned of an increased risk of a radiation leak if the high-voltage power line, damaged in fighting, is not repaired to the plant, which is occupied by Russian forces.

"Attempts to restore the external power supply to the site are in progress," the State Nuclear Regulatory Inspectorate of Ukraine said in a statement. When the external electricity supply is severed, an emergency diesel generator kicks in.
