After the incident at the Zaporizhia nuclear power plant, which was occupied by Russia, Ukrainian President Volodymyr Zelenskyy warned of further emergencies.
"I would like to emphasize that the situation remains very risky and dangerous," Zelenskyj said in a video speech on Saturday night.
"Each repetition (...) will again bring the power plant to the brink of disaster." Once again, he called for an early visit by international experts and the withdrawal of Russian troops from the nuclear power plant site, which they have been occupying since March.
On Thursday there was an emergency shutdown in Europe's largest nuclear power plant in southern Ukraine.
According to both sides, the reason was a damaged high-voltage line.
Ukraine cited Russian artillery shelling as the cause.
The occupiers, on the other hand, spoke of a fire as the trigger for a short circuit.
According to information from Kyiv, however, both of the last operated reactor units are now connected to the power grid again.
"Today at 9:15 p.m. (8:15 p.m. CEST) the second of the blocks stopped yesterday was connected to the power grid," said the state operator Energoatom on Friday evening in the Telegram news service.
The first of two reactors still in operation had already been restarted beforehand.
The nuclear power plant was captured by Moscow's troops in early March, shortly after the start of the Russian invasion of Ukraine.
The power station has been under fire for several weeks.
Both sides blame each other.
Concerns about a nuclear catastrophe are growing internationally.
