SEOUL, South Korea (AP) — North Korea said Tuesday it will escalate production of nuclear weapons material, including restarting a long-shuttered plutonium reactor, in what outsiders see as Pyongyang's latest attempt to extract U.S. concessions by raising fears of war.
A spokesman for the North's General Department of Atomic Energy said scientists will quickly begin work "readjusting and restarting" a uranium enrichment plant and a graphite-moderated, 5-megawatt reactor that could produce a bomb's worth of plutonium each year. Experts considered the uranium announcement to be a public declaration from Pyongyang that it will make highly enriched uranium that could be used for bomb fuel.
The plutonium reactor began operations in 1986 but was shut down in 2007 as part of international nuclear disarmament talks that have since stalled. It wasn't immediately clear if North Korea had already begun work to restart facilities at its main Nyongbyon nuclear complex. Experts estimate it could take anywhere from three months to a year to reactivate the reactor.
The announcement will boost concerns in Washington and among its allies about North Korea's timetable for building a nuclear-tipped missile that can reach the United States, although it is still believed to be years away from developing that technology.
The nuclear vows and a rising tide of threats in recent weeks are seen as efforts by Pyongyang to force disarmament-for-aid talks with Washington and to increase domestic loyalty to young North Korean leader Kim Jong Un by portraying him as a powerful military commander.
Hwang Jihwan, a North Korea expert at the University of Seoul, said the North "is keeping tension and crisis alive to raise stakes ahead of possible future talks with the United States."
"North Korea is asking the world, 'What are you going to do about this?'" he said.
