A Nuclear Reactor is designed and licensed to operate at a maximum of 1MW thermal powe Given the average fission energy of this reactor is 190MeV/ fission when operating at 750k power level, solve the following problems under this condition. (1) How many fission events per second (fission/sec) are there in this nuclear reactor? ( 9 points) (2) If the fuel volume is 40,000cm3, calculate the average fission reaction rate density (fissions /cm3sec)(6 points) (3) If the average fuel microscopic fission cross-section of fuel is 500 barns, given the metal dioxide fuel (MO2) density is 9.0g/cm3, and the average atomic mass of the metal is 238.5 , what is the average neutron flux level of this reactor? (10 points)
