Megatons to Megawatts

One-tenth of America’s electricity comes from fuel made from Russian nuclear warheads.  The Megatons to Megawatts program converts highly-enriched uranium in Russian weapons into low-enriched uranium that is used in US civilian nuclear power reactors.  The program reached an important milestone in early October - converting 255 metric tons of warhead material, the equivalent of over 10,000 weapons.

One-tenth of America’s electricity comes from fuel made from Russian nuclear warheads.  The Megatons to Megawatts program converts highly-enriched uranium in Russian weapons into low-enriched uranium that is used in US civilian nuclear power reactors.  The program reached an important milestone in early October - converting 255 metric tons of warhead material, the equivalent of over 10,000 weapons. 

The goal of Megatons to Megawatts is to complete conversion of 500 metric tons of HEU.  The program is set up to be commercially sustainable, thus taxpayers are not burdened with any costs.  The nuclear warheads are dismantled, the HEU is diluted in Russia, and then the resulting LEU is purchased by the United States Enrichment Corporation (USEC) and distributed to various power utility customers who then use the fuel to generate electricity.  The program is on schedule to complete its mission by 2015. 

In addition, USEC has teamed up with the US Department of Energy for the conversion and sale to reactors of 64 metric tons of excess US military HEU.  The US Megatons to Megawatts program is scheduled for completion in 2006.  The LEU fuel converted from US weapons is enough to power a 1,000-megawatt reactor for about 52 years, generating enough electricity for a city the size of Boston for 43 years. 

The Carnegie report Universal Compliance notes that the targeted Russian fissile material that has yet to be down-blended “remain[s] in weapon-usable form, to say nothing of the remaining Russian stockpile – which may amount to an additional 500 metric tons under uncertain security.”  The report recommends that “downblending needs to be accelerated to ensure the fastest possible elimination of this material.  Russia and the United States should agree to double the pace from 30 to 60 metric tons of HEU per year.”
