National Security Advisor Stephen Hadley says it appears the North Koreans have indeed shut down their main plutonium reprocessing facility at Yongbyon, about 100 kilometers north of Pyongyang. International inspectors 2 arrived in North Korea Saturday.

"The inspectors from the International Atomic Energy Agency are on the scene with their equipment," he said. "They will go to the facility and they will be able to confirm that in the next few days, but it appears that the facility is shut down."

Shutting down the reactor 3 was part of a February 13 deal agreed to by the six nations involved in talks on the North Korean nuclear crisis. These countries include the United States, North Korea, China, South Korea, Japan and Russia. They are to meet again Wednesday in Beijing .

In North Korea, the international inspectors are supervising the country's nuclear disarmament and rebuilding the surveillance system that was dismantled 5 when they were expelled from the country four years ago.

Speaking on Fox News Sunday, Hadley called the shutdown of the Yongbyon reactor a good first step. He warned that Washington is still concerned about a separate North Korean program to enrich uranium, which can also be used for nuclear weapons.

"It means they [North Korea] will no longer be able to reprocess to produce the nuclear weapons of those nuclear weapons that are made out of plutonium," he said. "We have concerns that they may have a covert 6 enrichment program."

The Bush administration says North Korea also has a nuclear program that relies on highly-enriched uranium. Pyongyang only publicly acknowledges its plutonium program.

Hadley stressed that the six-party agreement also requires North Korea to provide a full accounting 7 of all of its nuclear weapons, nuclear processing plants, and stored nuclear material it has already accumulated. He said that would include any uranium enrichment efforts, which he added will be one of the next subjects of discussion.

Under the February agreement, North Korea agreed to shut down its nuclear facilities in return for energy aid and other possible benefits. North Korea announced the shutdown of the Yongbyon reactor Saturday as it received its first shipment of more than 6,000 tons of fuel oil from South Korea.

The deal calls for North Korea to eventually receive one million tons of fuel oil. U.S. officials also are working on the possibility of replacing the armistice 8 agreement that ended the Korean War with a formal treaty.
