Safety and Security of Russian Nuclear Facilities: "The National Intelligence Council has issued an updated (November 2004) Annual Report to Congress on the Safety and Security of Russian Nuclear Facilities and Military Forces. (The 2002 edition is on the CIA website.) The 2004 edition repeats the judgment made in 2002 ‘undetected smuggling [weapons-grade and weapons-usable nuclear materials] has occurred, although we do not know the extent or magnitude of such thefts’ and again expressed concern about the total amount of material that could have been diverted."
