BEIJING — With a flash of explosives, North Korea on Friday demolished the cooling tower for its main nuclear reactor, the concrete shell vanishing into a cloud of smoke and dust aimed at showing that the authoritarian country is sincere about dismantling its nuclear weapons program.
Televising the demolition of the conical 60-foot-tall tower had been suggested by North Korea, whose leader, Kim Jong Il, is a cinema buff famous for his flare for the theatrical. It came a day after President Bush met a North Korean declaration about its nuclear program with an announcement that he would remove the Pyongyang government from the State Department's list of terrorism sponsors and lift other sanctions.
The demolition also provided Bush with dramatic, if largely symbolic, imagery he hopes will vindicate his administration's policies on confronting countries possessing weapons of mass destruction.
"It is a visual thing," said Daniel Pinkston, a Seoul-based senior analyst with the International Crisis Group, a think tank. "People get excited when they watch things blow up or fireworks, but the North Koreans are good with concrete."
Pinkston said that the cooling tower was basically a concrete chimney that could be rebuilt in a month, but that other facilities at the Yongbyon nuclear compound would take at least 18 months to restore. The North Koreans have shut down a plant that made fuel rods for its 5-megawatt reactor as well as a reprocessing plant that extracted weapons-grade plutonium from spent rods.
Secretary of State Condoleezza Rice, speaking in Japan, where she was attending a meeting of officials from the Group of 8 industrial nations, said the demolition was a small part of the process of nuclear dismantlement.
"That will not be the end of the story," Rice said. "We also must deal with proliferation. We must deal with highly enriched uranium. We must verifiably end all of North Korea's programs."
The controlled implosion took place at 5 p.m. local time, 20 hours after Bush announced the easing of sanctions at the White House. A small crowd gathered on a hillside at Yongbyon, a Soviet-era nuclear compound in the mountains 60 miles north of Pyongyang.
Video showed a puff emerging from the tower, then orange flame shooting out from the base. After a loud bang, the structure collapsed, enveloped by brown smoke.
