"North Korea has only a small supply of plutonium—material that it had stopped producing by 2008—and had more recently demonstrated an operational capability to enrich uranium, which would support a much larger arsenal of weapons given North Korea's huge deposits of natural uranium.... However, the seismic signals are useless in this regard. The question is, then, can the off-site environmental sampling analysis distinguish a plutonium explosion from a HEU explosion?"
