Over the past 73 years the concept of Nuclear Weapon Detonation Safety within the United States has evolved from a simple Safing Plug, used on Little Boy and Fat Man, to the Stronglinks, Weaklinks, Barrier and collocation used today. This tutorial begins with a review of the worst Nuclear Weapon Accidents the United States has had over the past 73 years. From there it goes into the safety concepts and analysis techniques that were used up to the late 1960's. The briefings then explore the concepts of modern Nuclear Weapon Detonation Safety, i.e. Enhanced Nuclear Detonation Safety (ENDS).
This presentation is known as the "Burned Board" briefing and is referenced in Eric Schlosser's book Command and Control.
