North Korea is upgrading its nuclear research center at a rapid pace, new satellite imagery analysis suggests, despite Pyongyang's commitment to denuclearization at a summit with the U.S..
The analysis from 38 North, a North Korea-focused website published by the Stimson Center in Washington, found that Pyongyang, in recent weeks, appears to have modified the cooling system of its plutonium-production reactor and erected a new building near the cooling tower.
华盛顿智库Stimson Center在专门研究朝鲜问题的网站38 North上发布的这份分析报告发现，近几周朝鲜似乎改进了钚生产反应堆的冷却系统，并在冷却塔附近建了一座新建筑。
New Construction could also be observed at the site's experimental light-water reactor, the report said.
The satellite pictures, captured on June 21, nine days after the Singapore summit meeting between President Donald Trump and North Korean leader Kim Jong Un, showed no immediate effort to begin denuclearization at North Korea's key nuclear research site.
The 38 North report, which is based on commercial satellite imagery of North Korea's Yongbyon nuclear research site captured by Airbus Defence & Space, found that the necessary infrastructure for operations at the experimental light-water reactor "appears externally complete."
38 North发布的这份报告是基于Airbus Defence & Space商业卫星拍摄的朝鲜宁边核研究基地的图像。该报告发现，维持实验用轻水反应堆运行的必要基础设施的外部似乎完整。
It wasn't clear whether operations at the reactor had begun, the report said.
Sen. Ed Markey (D., Mass.), the senior Democrat on Senate Foreign Relations East Asia Subcommittee, said the imagery suggests North Korea isn't adhering to its pledge to denuclearize.
