If a 1000 MWe (Megawatt electric) reactor operates with a capacity factor of 95% for an 18 month cycle, how much fuel is required for this period if the average burnup of the fuel over several cycles is 55,000 MWd/t (Megawatt days per metric ton of fuel). If 9.4 kg of natural uranium are required for each kg of reactor fuel and the natural uranium is sourced from low grade ores with an average assay of 0.07%, how much ore is required for this period of reactor operation?
