Zaporizhzhia Nuclear Plant City Without Power for 4 Days

The distinction that matters here is between the plant's safety systems and the city serving it: the outage stems from transmission damage outside Enerhodar, so off-site power reliability, not the reactors themselves, becomes the immediate concern. A prolonged loss of external supply at a large nuclear site is exactly the scenario that backup systems exist for, and their endurance is finite. Whether restoration happens before those backups are strained is the open question, and it is the kind of infrastructure risk that sits outside normal market pricing.
