Zaporizhzhia nuclear plant loses external power for 16 days

The extended reliance on diesel generators at Europe's largest nuclear plant shifts risk from a single-site operational issue to a broader energy-security concern, as any fuel-supply disruption would escalate consequences. This affects regional power stability and the safety calculus for all parties monitoring the facility. The key watchpoint is whether external grid connections can be restored before generator endurance or logistics become limiting factors, given this is now the second major outage of similar scale.
