Megatons to Megawatts Program Ends

The U.S.-Russian Highly Enriched Uranium (HEU) program, more commonly known as the Megatons to Megawatts agreement, was signed in 1993 and ended Dec. 31, 2013. Under the 20-year agreement Russia agreed to blend down a total of 500 metric tons of HEU, equivalent to about 20,000 bombs. As of November 2013, 475.2 metric tons of bomb-grade HEU had been recycled into 13,723 metric tons of low enriched uranium. The program provided the uranium to generate about 10 percent of America’s electricity from 1993 to 2013.


Now the program has ended, the U.S. will continue to purchase Russian uranium as part of the diverse global supply system. The Russian commercial fuel supply industry has grown into a robust and reliable trading partner. Whether the material comes from purely commercial supply or from additional downblending by Russia, the industry is confident the market system will continue to function well.
