fter South Korea’s NIS reported that parts of the Yongbyon nuclear complex, including the re

actor that is believed to produce weapons-grade plutonium, have not been active since the beginning of 2019.

  The International Atomic Energy Agency announced similar findings earlier this week. The organization’s gen

eral director, Yukiya Amano, said Monday the agency has not observed activity at several important facilities at Yo

ngbyon but did see “indications of the ongoing use of the reported centrifuge enrichment facility.”

  38 North said shortly before the summit that there was no indication that the site’s plutonium production reactor was

operating. A post in January said that Yongbyon appeared to be “well maintained” but its main facilities “did not

appear to be operating,” except for what is believed to be the uranium enrichment plant.
