This is not a thing on HN because this is not a thing in real life. Over the sixteen-year period between 2005 and 2020, nearly three-quarters of the 138,230 tonnes of natural uranium imported into France came from four countries:

Kazakhstan: 27,748 tonnes (i.e. 20.1%);

Australia: 25,804 (18.7%);

Niger: 24,787 (17.9%);

Uzbekistan: 22,197 (16.1%).

Only Niger is in Africa, and France has 10 years stored in case of geopolitical conflicts.
