Edward Marchesi The Zaporizhia nuclear complex , operated by Russian authorities in the southeastern region of Ukraine, was suddenly left without external power. The loss of the Ferosplavna power line forced the site to reactivate emergency diesel generators to ensure the nuclear fuel was cooled, a temporary measure expected to last approximately two weeks.
The International Atomic Energy Agency (IAEA) confirmed the outage, specifying that the cause and exact location of the disconnection are not yet known. Despite the lack of external power, the nuclear facility has sufficient fuel reserves to keep the emergency facilities operational for the estimated period.
Details of the power outage in Zaporizhia
The IAEA report indicates that, as of October 23, the Dniprovska main line remains inactive. Earlier, in late August, the site was already without power due to the collapse of the Ferosplavna line . A local ceasefire, negotiated by the agency, allowed for restoration work, but supply stability has not yet been achieved.
Automatic protection procedure and radiation levels
Moscow-installed management attributed the line shutdown to "automatic protection," claiming that radiation levels both within the site and in the monitoring zone were normal . Plant personnel, according to internal communications, are constantly monitoring all operating parameters, taking all necessary measures to maintain the safety of the six still inactive reactors.
Further attacks on Ukrainian energy infrastructure
Concurrent with the Zaporizhia crisis, Russian forces carried out a nighttime attack on power plants in the Dnipropetrovsk region . The attack disrupted electricity supplies to more than 600.000 residents, according to DTEK, the country's largest energy company. The Russian Defense Ministry justified the attack as targeting infrastructure used by the "Ukrainian military."
On the same day, an attack was reported on a substation in the Zhytomyr region , considered strategic for Ukraine's defense industry. In the Black Sea region, near Odesa, Russian forces sank a ship carrying foreign weapons, reinforcing the narrative of an offensive aimed at weapons procurement.
In response, a Ukrainian drone struck a tractor in Russia's Kursk region , killing a 40-year-old man, according to regional governor Alexander Khinshtein. This incident underscores the growing escalation of military action on both sides.
Overall, the combination of a nuclear hub without external power and a series of attacks on critical infrastructure makes Ukraine's energy situation extremely delicate. International authorities continue to urge the rapid restoration of power lines and the cessation of any operations that jeopardize nuclear safety.
