A uranium enrichment facility produces nuclear reactor fuel enriched to 4% ²³⁵U to fuel the reactor whose power to fuel consumption ratio is described by eq. (19.15)

For each tonne of natural uranium, the enrichment facility produces 130 kg of fuel. What is the concentration of ²³⁵U in the 870 kg of depleted uranium? Assume that the percentage of ²³⁵U in spent nuclear fuel removed from the reactor is the same as in natural uranium. How many tonnes of fuel are used in a year? Show that 211 tonnes of natural uranium is required to provide the 0.9 tonnes of ²³⁵U consumed by this reactor in one year. Repeat your analysis assuming that the enrichment facility produces 120 kg of fuel enriched to 5% and that the percentage of ²³⁵U in the spent fuel remains the same.
