    1. The problem statement, all variables and given/known data

    a particular nuclear power reactor operates at 1000MWe (megawatts electric) with an overall efficiency in converting fission energy to electrical energy of 30%. what mass of 235 U must fission in order for the power plant to operate for (a)one day, (b)one year?(c) if the energy were provided by burning coal instead of 235 U what would be the answers for a and b? (burning coal produces approximately 3.15x10^7 J/kg

    2. Relevant equations



    3. The attempt at a solution
