North Korea nuclear reversal off to good start - U.S.

By Jon Herskovitz

SEOUL (Reuters) - North Korea's first steps to roll back a nuclear arms program launched about 40 years ago are going well, a U.S. official said on Tuesday after visiting the North's plutonium-producing atomic complex.

Destitute North Korea struck a deal with regional powers last month to disable its Soviet-era nuclear complex in exchange for aid and an end to its international ostracism.

"I think we are off to a good start," U.S. State Department official Sung Kim said at Incheon airport near Seoul, according to a pool report. Kim was with a team of U.S. nuclear specialists who arrived in North Korea last week.

He said steps had been taken to reverse the operations at all three of the key facilities -- the North's aging reactor, a plant that produces nuclear fuel and another that turns spent fuel into arms-grade plutonium.

"Our North Korean colleagues have actually done a considerable amount of preparatory work on all three facilities."

Kim said he believed disablement at one facility would be completed this week. The team wants irradiated fuel rods removed from the reactor, which experts said would halt its operations and could pave the way for further decommissioning steps.

The deal requires North Korea to disable the three plants by the end of 2007, provide a list of its nuclear arms activity, account for all its fissile material and answer U.S. suspicions of having a clandestine program to enrich uranium for weapons.

In Washington, State Department spokesman Sean McCormack said the beginning of disablement marked the start of "a qualitatively new phase."
