That is not exactly what 38 North, on whom Wally based their headline, said. This is exactly what 38 North said:
"Commercial satellite imagery from June 21 indicates that improvements to the infrastructure at North Korea’s Yongbyon Nuclear Scientific Research Center are continuing at a rapid pace.
...
"Continued work at the Yongbyon facility should not be seen as having any relationship to North Korea’s pledge to denuclearize. The North’s nuclear cadre can be expected to proceed with business as usual until specific orders are issued from Pyongyang."

I recognize that that last sentence begs the question.
