MOSCOW, August 21 (RIA Novosti) - The U.S. Department of Commerce has approved a new long-term contract for imports by a U.S. company of Russian low-enriched uranium, Russia's state nuclear company Atomenergoprom said on Friday.

On August 19, the department "approved a direct contract for deliveries by Techsnabexport [Atomenergoprom's uranium export arm] of enriched uranium to the U.S. energy company Constellation Energy Nuclear Group," the company said in a statement.

The contract is the sixth in a series of deals between U.S. firms and Techsnabexport signed in May-July of this year.

The department earlier approved two Techsnabexport contracts with electricity supplier and distributor Exelon Corporation, and is currently considering approval of three other contracts with the fuel industry servicing company Fuelco.
