Culmination of the Four-Year Effort: GTRI Contributions to Global Nuclear Material Security

President Barack Obama in Prague, Czech Republic April 5, 2009“Today I am announcing a new international effort to secure all vulnerable nuclear material around the world within four years. We will set new standards, expand our cooperation with Russia, pursue new partnerships to lock down these sensitive materials.”

As President Obama’s Four-Year Effort comes to a close this month, NNSA is highlighting the work carried out by its nonproliferation programs to reduce the threat of vulnerable nuclear material around the world. In support of the Four-Year Effort, NNSA’s Global Threat Reduction Initiative (GTRI) led the effort to secure and, when possible, eliminate these dangerous materials. Working at civilian sites in more than 100 countries, GTRI executes its mission by converting research reactors and isotope production facilities from using HEU to using low-enriched uranium (LEU) fuel/targets, removing and/ or dispositioning excess nuclear and radiological materials, and protecting nuclear and radiological materials from theft. As such, GTRI was at the forefront of implementing the Four-Year Effort.

Under the effort, GTRI accomplished the following major tasks:

  • Removed and/or dispositioned nearly 3,000 kilograms of HEU and plutonium, bringing the lifetime total to more than 5,060 kilograms—enough material to produce more than 200 nuclear weapons.
  • Removed all HEU material from 11 countries plus Taiwan, bringing the lifetime total to 27 locations: Austria, Brazil, Bulgaria, Chile, Colombia, Czech Republic, Denmark, Georgia, Greece, Hungary, Iraq, Latvia, Libya, Mexico, Philippines, Portugal, Romania, Serbia, Slovenia, South Korea, Spain, Sweden, Taiwan, Thailand, Turkey, Ukraine, and Vietnam.
  • Secured more than 10 metric tons of HEU and 3 metric tons of weapons-grade plutonium from Kazakhstan’s BN-350 reactor and transferred the material to long-term storage.
