The satellite image shows the activities still taking place at Pyongsan Uranium Concentration Plant, proving that North Korea is still promoting the nuclear program.

A satellite image of Maxar Technologies taken in March shows many activities taking place at Pyongsan Uranium Concentration Plant in North Hwanghae Province in North Korea, which produces the "golden cake", the urianium powder obtained from

"The plant is important to the North Korean leadership, as well as its nuclear weapons research and development programs. The fact proves this when limited human and financial resources are allocated.

Experts said the "yellow cake" uranium could be enriched to make a nuclear weapon, but could also be used as fuel for a light-water reactor tested by a nuclear science research facility in Yongbon.
