Assume that in 2010 the United States will need 2.0×1012 watts of electric power produced by thousands of 1000 MW power plants. These will almost certainly be powered by either coal or nuclear reactors. If all the energy is provided by U-235 burning reactors, how many tonnes of U-235 will be needed annually? NOTE: Rather than using the exact energy from problem 1, please assume that fission of U-235 releases a "rounded" 8.E13 J/kg (Assume a realistic efficiency of 45...
