Approximately how much electricity is generated from nuclear power each year in the US? Given the average fuel burnup above, calculate a yearly average demand for r eactor fuel and SWU for the US. What is the cost of this fuel? If the entire enrichment capacity were to be derived from centrifuge machines with a capacity of 45kgSWU/yr, how many machines would be required? What would be the energy requirement for this enrichment per kg of fuel (product) and yearly total required? What is the energy input for enrichment (via centrifuge method) as a fraction of the electricity generated by the fuel produced?
