The Zaporizhzhia Nuclear Power Plant lost all external power for the fourteenth time of the war on or around Friday 17 April, and again days later on the fifteenth occasion1. The main 750 kV Dniprovska line, disconnected since 24 March at 23 days on 14 April, was repaired during the week via an IAEA-mediated local ceasefire; the plant then lost power twice more. Repair crews on the 330 kV Ferosplavna-1 backup feeder found additional damage 1.8 kilometres from the switchyard. As of Wednesday 22 April, one external line was running. Rafael Grossi, the IAEA Director General, said the agency is negotiating a further ceasefire to repair the main feeder.
The operational trajectory and the administrative one now run in opposite directions. Rostekhnadzor, Russia's nuclear regulator, issued 10-year operating licences for ZNPP units 1 and 2 through 2036 earlier in April. The paperwork runs through the next decade; the physical plant runs on a single external cable. The 1.8 km Ferosplavna-1 fault widens the repair footprint beyond the previous cable-break scope, and the fortnightly pattern of outage and repair is not a stable operating regime for a nuclear plant under any framework.
The plant is in cold shutdown, which reduces the fuel-damage timeline of a total loss relative to an operating reactor. That floor is the argument against panic. The argument against complacency is duration: emergency diesel generators carried the site for roughly 90 minutes during the 13th incident, and every additional outage within a week narrows the margin before the diesels run into a ceasefire negotiation that has not yet been concluded. The operational gain of an IAEA-brokered ceasefire lasted less than a week; the next one will have to hold longer than that.
