International Atomic Energy Agency teams are currently conducting emergency inspections across Ukraine's electrical substations — the ones keeping nuclear facilities running safely. Why the rush?

The agency's boots-on-the-ground assessment this month will determine just how vulnerable Ukraine's nuclear network has become.
