"Nearly 10 percent of the 40 million pounds of U3O8e [uranium] delivered in 2018 was US-origin uranium at a weighted-average price of $45.26 per pound," the release said. "Foreign-origin uranium accounted for the remaining 90% of deliveries at a weighted-average price of $38.11 per pound."
Uranium originating in Kazakhstan, Russia and Uzbekistan accounted for 40 percent, the release added.
US uranium producers, which claim that just 7 percent of the uranium used in the United States is home grown, are lobbying for a quota system that would guarantee 25 percent of uranium used in US reactors is supplied by domestic producers, according to published reports.
Major utilities that operate nuclear reactors fear that quotas would increase costs in an industry already burdened by competition with other energy sources.
