The United States Secretary for Energy Jennifer Granholm said on Friday that the US is concerned with "Russia’s reckless actions and violations of nuclear safety principles."
In a number of tweets, Granholm noted that though the Ukrainian detectors have not registered signs of radiological emissions, the US remains worried about the lack of data from safety monitors at nuclear plants in Chernobyl and Zaporizhzhia, which gravelly disables the international tracking of the conditions in the sites.
