Nuclear Disarmament Kazakhstan
NPT Non-Nuclear Weapon State
Formerly Possessed Nuclear Weapons
- Kazakhstan possesses no nuclear weapons. 
- Kazakhstan formerly had 1,410 Soviet strategic nuclear warheads placed on its territory and an undisclosed number of tactical nuclear weapons. 
- One of the Soviet Union's two major nuclear test sites was located at Semipalatinsk, where at least 460 nuclear tests took place. 
Estimated Destructive Force
Progress in Disarmament
- Kazakhstan transferred all of its Soviet-era nuclear weapons to the Russian Federation by April 1995. 
- As part of the Nunn-Lugar Cooperative Threat Reduction Program the United States assisted Kazakhstan in removing 1,322 lbs of HEU from the Ulba metallurgical plant in Ust-Kamenogorsk.  The United States paid Kazakhstan $25 million for the HEU transfer. 
- The Semipalatinsk nuclear test site was officially closed in 1991. 
- From 1995 to 2001, as part of the Nunn-Lugar Cooperative Threat Reduction Program, the United States assisted Kazakhstan sealing 13 bore holes and 181 tunnels at the test site. 
Security risks, increasingly scrutinized after 9/11, revealed the possibility of scavengers accessing plutonium in the sealed bore holes and tunnels at the site. Between 2001 and 2012 scavengers came within yards of the unguarded fissile material, although there is no indication that any plutonium was removed.  October 2012 marked the ceremonial end of the 17-year operation to secure the Semipalatinsk nuclear test site.
