 In 2006, the Russian government announced plans to build the world's first international uranium enrichment center at an existing nuclear facility in Angarsk, a city on the river Angara some downstream from the lake's shores.Critics and environmentalists argued it would be a disaster for the region and are urging the government to reconsider.After enrichment, only 10% of the uranium-derived radioactive material would be exported to international customers, leaving 90% near the Lake Baikal region for storage.
