North Korea to restart nuclear reactor to fuel arms program
North Korea said Tuesday it would restart a nuclear reactor to feed its atomic weapons programme, in its clearest rebuff yet to UN sanctions at the heart of soaring tensions on the Korean peninsula.
The announcement was the latest in a series of aggressive statements by Pyongyang that have prompted the deployment of nuclear-capable US B-52s, B-2 stealth bombers and a US destroyer to South Korea on “deterrence” missions.
A Pyongyang government nuclear energy spokesman said the move would involve “readjusting and restarting” all facilities at the main Yongbyon nuclear complex, including a uranium enrichment plant and a five-megawatt reactor.
The aim was to “bolster the nuclear armed force both in quality and quantity” as well as solve electricity shortages, the spokesman was quoted as saying by the official KCNA news agency.
The North shut down the Yongbyon reactor in July 2007 under a six-nation aid-for-disarmament accord, and destroyed its cooling tower a year later.
It was the sole source of plutonium for the nuclear weapons programme. Bringing it back on line will allow the North to restock its dwindling plutonium supply, which experts believe is enough for only four to eight bombs.
North Korea revealed it was enriching uranium at Yongbyon in 2010 when it allowed foreign experts to visit the centrifuge facility there, but insisted it was low-level enrichment for energy purposes.
The mention of “readjustment” will fuel concerns that it will be upgraded — a relatively simple technical process — into a facility for openly producing weapons-grade uranium, even if it has not already been converted.
Tuesday’s announcement triggered international alarm, with North Korea’s only major ally China among the first to voice regret at Pyongyang’s decision.
“We call on relevant parties to keep calm and exercise restraint,” said foreign ministry spokesman Hong Lei.
The South Korean foreign ministry said the move was “very regrettable” and the North should “honour agreements and promises that have been made in the past”.
Kim Yong-Hyun, a North Korea expert at Seoul’s Dongguk University, said the nuclear move was in a different league from the military bluster of recent weeks.
“This goes beyond mere provocation. It’s a strong, tangible move and perhaps the one that will force the US into the direct dialogue Pyongyang wants,” Kim said.
The prospect of North Korea on a joint plutonium and uranium enrichment path is a hugely worrying one for the international community.
The North has substantial uranium ore deposits which provide a quick route to boosting reserves of fissile material, while plutonium has the advantage of being far easier to miniaturise into a deliverable nuclear warhead.
Many observers believe the North has been producing highly-enriched uranium in secret facilities for years, and that the third nuclear test it conducted in February may have been of a uranium bomb.
Its previous tests in 2006 and 2009 were both of plutonium devices.
The Korean peninsula has been caught in a cycle of escalating tensions since the February test, which followed a long-range rocket launch in December.
Subsequent UN sanctions and annual South Korea-US military exercises have been used by Pyongyang to justify a wave of increasingly dire threats against Seoul and Washington, including warnings of missile strikes and nuclear war.
But the tough talk has yet to be matched by action on the ground.
“Despite the harsh rhetoric we’re hearing from Pyongyang, we are not seeing changes to the North Korean military posture, such as large-scale mobilisations,” said White House spokesman Jay Carney.
The nuclear announcement followed a top-level meeting Sunday of the North’s ruling party, at which young leader Kim Jong-Un stressed the importance of upgrading the country’s nuclear arsenal.
“Modernisation of the atomic energy industry is a key to… developing the technology to produce miniaturised, lighter nuclear weapons to a whole new level,” Kim said.
The next day the North’s parliament adopted a law enshrining North Korea’s status as a nuclear weapons state.
