U.S. Tests Plutonium to Gauge Nuclear Arms Readiness

Sandia National Laboratories carried out a plutonium experiment this past spring to assess the working order of the U.S. nuclear arsenal, Kyodo News reported on Tuesday.

Such a test previously occurred at the New Mexico facility late last year.


The United States periodically undertakes these experiments using a "Z machine" that produces X-rays powerful enough to mimic the fusion reactions of nuclear weapons, allowing for the study of plutonium behavior without the detonation of an atomic device.
