North Korean nuclear weapons, 2022

Abstract

ABSTRACT The Nuclear Notebook is researched and written by Hans M. Kristensen, director of the Nuclear Information Project with the Federation of American Scientists, and Matt Korda, a senior research associate with the project. The Nuclear Notebook column has been published in the Bulletin of the Atomic Scientists since 1987. This issue examines North Korea’s nuclear arsenal. The authors cautiously estimate that North Korea may have produced enough fissile material to build between 45 and 55 nuclear weapons; however, it may have only assembled 20 to 30.
