International Atomic Energy Agency (IAEA) chief Rafael Grossi arrived in Kyiv on Tuesday and inspected an electricity distribution substation, warning that attacks on Ukraine's power grid could pose a risk of a nuclear accident by disrupting supply.

Russia's continued attacks against Ukraine's power grid heighten the risk of a nuclear accident, International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi warned during his visit to Kyiv on Feb.

Rafael Grossi posted on X explaining how a direct attack on Kyivska electrical substation can affect nuclear safety. He visited the substation with Ukraine's Energy Minister German Galushchenko.

Despite more than a year of warnings that critical Ukrainian nuclear energy infrastructure sites are vulnerable to potential Russian attacks, Ukraine’s Energy Ministry has failed to act swiftly to protect them,

Russian attacks on Ukraine's energy system could create a risk of a nuclear accident due to a failure in the supply of electricity from nuclear power plants. This could happen as a result of a strike on power substations,

Only in the fall, after Ukrainian intelligence agencies warned of potential strikes targeting nuclear transmission facilities, was action taken to begin building protection, the officials said — far too late in the event of an attack.
