MOSCOW, March 28 (RIA Novosti) - A subsidiary of Russia's top civilian nuclear power company said Tuesday it would ensure stable nuclear fuel supplies to South Korea.

Tekhsnabexport (Tenex), a producer and exporter of nuclear materials, said it was considering various options for expanding its presence in the Asia Pacific, rejecting allegations by U.S. company Palmco that it was seeking to crowd the Americans out of the South Korean nuclear market.

The Russian and U.S. companies have been involved in a long running legal dispute.

Their cooperation began in 1988, when the two companies signed a long-term contract for the delivery of low-enriched uranium for nuclear power plants in South Korea.

Tenex said it was planning to continue cooperation with Palmco under earlier contracts for nuclear fuel supplies to South Korea.

Tekhsnabexport has been supplying nuclear materials (low-enriched uranium) to South Korea for almost two decades.
