President Biden on Monday evening signed a bipartisan bill prohibiting Russian imports of enriched uranium, the main fuel used by nuclear power plants, a move intended to cut off one of the last significant flows of money from the United States to Russia amid the war in Ukraine.
Congress took swift action to ban Russian oil and gas imports a month after the February 2022 invasion of Ukraine. But sanctions on uranium imports have taken much longer, in part because Russia supplies roughly 20 percent of U.S. nuclear fuel, leading some lawmakers to fear disruptions to the nation’s 93 nuclear reactors.
