Russia’s state-owned nuclear energy firm Rosatom took over Zaporizhzhia Nuclear Power Plant in Enerhodar, Ukraine, after it invaded. On Tuesday, CNN reported that the Department of Energy (DOE) sent Russia an official letter on March 17, 2023, explaining that the power plant “contains US-origin nuclear technical data that is export-controlled by the [U.S.] Government” and could undermine U.S. national security if it fell into the wrong hands.
