A U.S.-based think tank says recent satellite images show one of the two uranium enrichment plants in North Korea isn't showing any sign of new activity.<br />According to the Center for Strategic and International Studies on Wednesday,... the Pakchon plant was highly active until the mid-1990s,... but has since gone dark,... and is currently being maintained with no major changes or obvious activities.<br />However, experts say that, because no international inspections have been conducted on the site for more than 25 years,... a thorough check would be necessary for a denuclearization agreement to be achieved between the North and the U.S.<br /><br />
