Moscow, Aug 21 (RIA Novosti) Washington has approved a long-term contract for imports by a US company of Russian low-enriched uranium, Russia's state-run nuclear company Atomenergoprom said Friday.

On Aug 19, the US commerce department 'approved a direct contract for deliveries by Techsnabexport (Atomenergoprom's uranium export arm) of enriched uranium to the US energy company Constellation Energy Nuclear Group,' the company said in a statement.
