The National Nuclear Security Administration established the Global Threat Reduction Initiative (GTRI) in the Office of Defense Nuclear Nonproliferation to, as quickly as possible, identify, secure, remove and/or facilitate the disposition of high risk vulnerable nuclear and radiological materials around the world that pose a threat to the United States and the international community.
Mission
In 2004 NNSA established the Global Threat Reduction Initiative (GTRI) in the Office of Defense Nuclear Nonproliferation to, as quickly as possible, identify, secure, remove and/or facilitate the disposition of high risk vulnerable nuclear and radiological materials around the world that pose a threat to the United States and the international community.
GTRI’s mission is to reduce and protect vulnerable nuclear and radiological material located at civilian sites worldwide. GTRI achieves its mission via three initiatives which provide a comprehensive approach to preventing terrorists’ access to nuclear and radiological materials. These three initiatives are:
Accomplishments
Since its inception, GTRI has accelerated its nuclear security efforts and made significant progress to reduce the risk posed by vulnerable civilian nuclear and radiological materials, which could be used by terrorists to make an improvised nuclear device or a radiological dispersal device (RDD), or "dirty bomb.”
GTRI has converted or verified the shutdown of 82 HEU fueled research reactors; removed more than 3,400 kilograms of HEU and plutonium – enough for more than 135 nuclear bombs; secured more than 775 bombs worth of HEU and plutonium associated with the BN-350 reactor in Kazakhstan; secured nearly 1,200 radiological sites around the world containing more than 20 million curies – enough for thousands of dirty bombs; and recovered more 31,000 orphan and disused radiological sources containing more than 18 million curies.
GTRI has greatly accelerated its efforts to reduce nuclear and radiological threats since President Obama’s pledge in Prague in April 2009 to secure all vulnerable nuclear material in four years.
