Russian state uranium trader Techsnabexport said on Thursday it would sign several contracts on low-enriched uranium supplies with major U.S. energy companies before the end of the year.

Techsnabexport and three U.S. companies affiliated with the FuelCo Group signed on Tuesday three long-term low-enriched uranium supply contracts worth a total of $1 billion.

"Another four such contracts will be signed before the end of the year," Techsnabexport CEO Alexei Grigoryev said.

Under the contracts signed on Tuesday, enriched uranium will be supplied directly to the U.S. companies from 2014 through 2020.

He also said Russia is ready to discuss the establishment of a low-enriched uranium storage facility in the U.S. to ensure long-term supplies to consumers.

Earlier this month, Russia and the United States signed an agreement on civilian nuclear cooperation.

The countries are also cooperating in the nuclear sphere on the HEU-LEU project.

The HEU-LEU contract, also known as the Megatons to Megawatts agreement, was signed in February 1993 and expires in 2013. It aims to convert 500 metric tons of highly-enriched uranium (HEU), the equivalent of approximately 20,000 nuclear warheads, from dismantled Russian nuclear weapons into low-enriched uranium (LEU), which is then converted into nuclear fuel for use in U.S. commercial reactors.

Techsnabexport, a Russian company that exports goods and services produced by the nuclear power sector, is integrated into state nuclear group Atomenergoprom.
