1. The problem statement, all variables and given/known data The electric power generated by a single average size nuclear reactor block is between 400 and 800 MW. The fission of one 235U nucleus generates 185 MeV energy on average. What is the total mass of the fuel rods loaded into a 760 MW reactor for a one year period, if the fuel rods contain 3.50 percent of 235U? Assume that the overall thermodynamic efficiency of converting heat to electric energy is 33.0 percent. 3. The attempt at a solution So to start out I multiply the 185MeV by 3.5% then from there I am lost. Help in any way is appreciated, thanks.
