The New Safe Confinement (NSC) at Ukraine's Chernobyl site sustained significant damage from two recent drone strikes.The latest strike caused a fire in the NSC's insulation and punched a hole in the dome, leading the International Atomic Energy Agency (IAEA) to confirm the structure "has lost its primary safety functions."While no immediate radiation leaks have been detected, experts warn of risks including radioactive dust leaks and potential reactivation of nuclear fuel by rain.
