May 18 (Reuters) - Uranium fuel supplier USEC Inc (USU.N) and its French competitor Areva (CEPFi.PA) said they agreed to settle pending appeals related to an anti-dumping case involving imports of French low-enriched uranium.

Under the settlement, the parties will immediately withdraw or request dismissal of all pending appeals and U.S. Department of Commerce proceedings.

USEC said it expected to realize about $70 million no earlier than the fourth quarter from estimated duties deposited by Areva's holding company, Eurodif SA, as a result of the settlement.

"This is expected to bring to an end all pending litigation and administrative proceedings regarding DOC's 2002 anti-dumping duty order, which now is expected to remain in place until at least... 2012," the company said.

In January, the U.S. Supreme Court ruled in favor of USEC and the federal government, when it said that uranium imports under all kinds of contracts were subject to U.S. trade laws. The ruling was a defeat for Areva, which had supplied the imported uranium at issue in the case.

Shares of USEC were trading up 6 percent at $4.78 Monday morning on the New York Stock Exchange.
