Called the National Enrichment Facility, it is located 5 miles (8.0 km) east of Eunice, New Mexico, and is operated by Urenco's subsidiary Louisiana Energy Services (LES).

ETC provides enrichment-plant design services and gas-centrifuge technology for enrichment plants through its subsidiaries in the UK (Capenhurst), Germany (Gronau and Jülich), the Netherlands (Almelo), France (Tricastin) and the U.S. (Eunice, New Mexico).

The case was expected to be ready by the end of 1985 but was delayed because Urenco argued that, despite having enriched uranium of Namibian origin since 1980, it was impossible to tell where specific consignments came from.

When the case finally reached court in July 1986, the Dutch government took Urenco's line, claiming not to have known where the uranium had been mined.

In March 2009, there were protests about the largest-ever load of depleted uranium hexafluoride (DUF6) being transported from Germany to the Siberian town Seversk.
