Water shortage and flooding threaten Ukraine's largest nuclear plant.

The Zaporizhzhia nuclear power plant in Ukraine is facing a water shortage after a critical dam holding back the Kakhovka Reservoir collapsed. Workers have filled up ponds, canals, and a small artificial lake next to the plant to secure water for the plant's safe operation. The plant has already endured power failures, fires, shelling, and abuse of workers by Russian occupiers, all of which are eroding its defenses. The reactors aren't in trouble just yet, but the plant will need to find more water at some point. If the reactors do run out of water, then the fuel inside could start to melt down, leading to some kind of radioactive release.
