"North Korea's Oct. 9 Nuclear Test: Successful or Failed?"

Conference Proceedings

By Hui Zhang, Senior Research Associate, Project on Managing the Atom

In this paper, Zhang examined if the test was successful. Based on a technical analysis, Zhang concluded that: whether North Korea’s Oct. 9 nuclear test was successful or failed would be dependent on North Korea’s designed yield. If North Korea planned a yield of 4 kt (as told to China), it would be not a failed test. It could show that North Korea already had confidence to explode a nuclear device and pursued a much more compact warhead for its missiles. Thus, it is urgent to negotiate for dismantling North Korean nuclear and long-range missile programs.

"Off-Site Air Sampling Analysis And North Korean Nuclear Test"

Conference Proceedings

By Hui Zhang, Senior Research Associate, Project on Managing the Atom

In this paper, Zhang explores what information could have been obtained from offsite air sampling analysis. Specifically, he examines how to use the activity ratios of xenon isotopes to identify the North Korean nuclear test and whether the off-site air sampling analysis would be able to distinguish a test from a plutonium-bomb and a HEU bomb.
