- U-235 sphere the size of a Tootsie Pop Assume that a spherical volume of pure U-235 is the size of a Tootsie Pop. The per capita electrical energy usage (i.e., per person per year) in the U.S. is 11,496 kw-hrs a) How many years would this amount of U-235 power the average person if all the U-235 atoms were fissioned? b) What would be the approximate volume of the waste produced, when the entire sample has fissioned? (Describe this qualitatively.) Assumptions to use: • Pop diameter = 1.25 inch • Density of the U-235 sample = 18.95 g/cc . The atomic mass is 235.044 amu • 180 MeV of heat energy are available from each fission . The efficiency for thermal to electric conversion is 0.32 .
