"Due to power surges, the New Safe Confinement — the key structure that isolates the destroyed 4th reactor of the Chornobyl Nuclear Power Plant and prevents the release of radioactive materials into the environment — was left without electricity," the Energy Ministry said.

A Russian attack on an energy facility in the town of Slavutych in Kyiv Oblast caused a several hours-long blackout at the Chornobyl Nuclear Power Plant on Oct.
Slavutych, a satellite town of the Chornobyl plant in northern Ukraine, was built to house evacuated plant personnel following the 1986 disaster.
1, a Russian drone attack on a substation in Slavutych caused power outages in the city and parts of the neighboring Chernihiv Oblast, according to local authorities.
The Energy Ministry also reported an "emergency situation" at several facilities within the Chornobyl plant.
"Due to power surges, the New Safe Confinement — the key structure that isolates the destroyed 4th reactor of the Chornobyl Nuclear Power Plant and prevents the release of radioactive materials into the environment — was left without electricity," the statement read.
The blackout at the Chornobyl Nuclear Power Plant lasted over three hours following Russian strikes, President Volodymyr Zelensky later said.
"The Russians could not have been unaware that a strike on the facilities in Slavutych would have such consequences for Chornobyl.
And it was a deliberate strike, in which they used more than 20 drones — according to preliminary estimates," he said.
1, the Energy Ministry said that power supply to all facilities at the Chernobyl nuclear power plant had been fully restored after the outage.
The ministry added that radiation levels at the site remain within normal limits and pose no threat to the population.
In February, a Russian Shahed-type drone struck the New Safe Confinement over Chornobyl's destroyed 4th reactor.
The structure built to contain radioactive material was damaged, although no serious radiation leaks were caused.
The importance of the report depends on confirmed records, named authorities and any follow-up statements that clarify the scale, timing and public impact of the development.
The next useful information will be the most direct record available: an official notice, a named statement, an updated dataset, a court filing, a regulator note or a corrected public advisory.
