Salvaged bomb material now generates about 10 percent of electricity in the United States — by comparison, hydropower generates about 6 percent and solar, biomass, wind and geothermal together account for 3 percent. But at times, recycled Soviet bomb cores have made up the majority of the American market for low-enriched uranium fuel. Today, former bomb material from Russia accounts for 45 percent of the fuel in American nuclear reactors, while another 5 percent comes from American bombs, according to the Nuclear Energy Institute, an industry trade association in Washington.
