BETHESDA, Md. - USEC Inc. (NYSE: USU) and the Solicitor General of the United States presented oral arguments before the U.S. Supreme Court today urging that all imports of low enriched uranium (LEU) should be subject to the U.S. antidumping law regardless of the type of contract under which the uranium is imported. The Supreme Court is expected to render a decision in United States v. Eurodif S.A. and USEC Inc. v. Eurodif S.A. in the first half of 2009.

In their oral arguments, USEC and the U.S. government asked the Supreme Court to reverse the March 2005 decision by the U.S. Court of Appeals for the Federal Circuit that imports of LEU under SWU (separative work unit) contracts fall outside the scope of the U.S. antidumping law. Reversal of the Federal Circuit’s decision would restore certainty to the U.S. nuclear fuel market that the dumping of LEU can be restricted. The risk of dumping of foreign-produced LEU imports continues to pose a significant threat to the U.S. enrichment industry and the economic well being of its workers and the communities in which they live.

USEC Inc., a global energy company, is a leading supplier of enriched uranium fuel for commercial nuclear power plants. The company is deploying its next generation uranium enrichment technology – the American Centrifuge – in Piketon, Ohio. The United States Enrichment Corporation, a subsidiary of USEC Inc., runs America’s only operating uranium enrichment plant in Paducah, Ky., and does contract work for the U.S. Department of Energy in Piketon.
