Material Control and Accountability at Lawrence Livermore National Laboratory
Lawrence Livermore National Laboratory supports the Department of Energy's core mission of maintaining a safe, secure, and reliable nuclear weapons stockpile and applying scientific expertise toward the prevention of the proliferation of weapons of mass destruction and terrorist attacks. Livermore personnel perform tests and study various characteristics of nuclear material, to include accountable nuclear material, which is a collective term that encompasses all materials so designated by the Secretary of Energy in quantities that require special control. Examples of these materials include plutonium, enriched uranium, americium, and depleted uranium.
