New activity at N. Korea nuke site ahead of Trump summit
TOKYO — Increased activity at a North Korean nuclear site has once again caught the attention of analysts and renewed concerns about the complexities of denuclearization talks as President Donald Trump prepares for a summit with Kim Jong Un in the coming weeks.
Satellite imagery taken last month suggests the North has begun preliminary testing of an experi- mental light water reactor and possibly brought another reactor online at its Yongbyon Nuclear Research Center.
Both could be used to produce the fissile materials needed for nuclear bombs.
The findings come at a particularly sensitive time. Trump and Kim are planning to meet by May, according to officials, and denuclearization will likely be the biggest topic on their agenda if they do meet. North Korea tested its biggest nuclear device to date last September. Pyongyang claims it was an H-bomb.
While the North hasn’t conducted any tests since, or test-launched any longrange missiles since Nov. 28, the heightened activity at the Yongbyon complex could be ominous.
According to an analysis in Jane’s Intelligence Review published earlier this month, a testing program is now underway at the experimental reactor, which means it could become operational with “little warning later in 2018 or in 2019.” It said the preliminary testing follows increased activity throughout 2017.
The reactor was completed five years ago and is primarily designed to generate electricity for civilian use. But it could also be used to produce plutonium or tritium.
The Jane’s report cautioned that without international inspections it’s impossible to tell for sure if it’s being used to produce civilian electricity or weaponsgrade material for bombs. The reactor has been linked to the local electricity grid and is believed to be potentially able to power a city of about 50,000 if operated at full capacity.
In a separate report posted on 38 North, a website that specializes in North Korea news and analysis, experts said they have detected activity at another reactor in the Yongbyon complex, which is located north of Pyongyang, that could be an even bigger concern.
Imagery of Yongbyon’s 5-megawatt reactor sug- gests it was brought into operation recently. The website said that would mean “North Korea has resumed production of plutonium presumably for its nuclear weapons program.”
It said commercially available satellite imagery of the reactor revealed steam vapor plumes emanating from the generator hall, along with river ice melt near the reactor. Additionally, North Korean technicians might have stepped up efforts to conceal signs of the reactor’s operations.
