A U.S. congressional delegation will visit North Korea to sound out the possibility of a denuclearization program to the communist country.

Radio Free Asia said an aide to U.S. Republican Senator Richard Lugar will head for Pyongyang February 12th and visit nuclear facilities in Yongbyon during his stay.

The aide will discuss with North Korean diplomats giving nuclear scientists there civilian professions in line with the “Nunn-Lugar Cooperative Threat Reduction Program.”

The program is a peaceful denuclearization tool that helped Russia and Ukraine scrap their nuclear programs in the 1990s after the Soviet Union collapsed.

Six U.S. nuclear experts will also go to Pyongyang for talks with North Korean nuclear technicians.

The visit will come after the top U.S. envoy to the six-party nuclear talks, Christopher Hill, speaks at a congressional hearing.

Radio Free Asia said it expects the visit to help Congress revise its policies on the North Korean nuclear problem.
