What Happens When a Nuclear Site Is Hit?

Strikes hit several Iranian nuclear-related sites, including Natanz, Ardakan, Khondab, and areas near Isfahan, amid the widening US-Iran conflict.

The IAEA said it had not detected off-site radiation contamination after the attacks.

Experts say a direct hit does not usually trigger a major radiation disaster if reactors shut down safely.

The real danger comes if damage affects cooling, backup power, or containment systems, which could lead to contamination and wider disruption.

Coastal or water infrastructure damage could also threaten desalination and supply systems, raising cross-border risks.
