## Notes

In March 2011, the approx. US $ cost to get 1 kg of uranium as UO2 reactor fuel (at current spot uranium price):

Uranium: 8.9 kg U3O8 x $146 US$ 1299

Conversion: 7.5 kg U x $13 US$ 98

Enrichment: 7.3 SWU x $155 US$ 1132

Fuel fabrication: per kg US$ 240

Total, approx: US$ 2769

At 45,000 MWd/t burn-up this gives 360,000 kWh electrical per kg, hence fuel cost: 0.77 c/kWh.

Fuel costs are one area of steadily increasing efficiency and cost reduction. For instance, in Spain the nuclear electricity

Half the cost is fuel enrichment and fabrication, which is dealt with elsewhere, so I've taken half of 0.77c/Kwh. I've assumed this is the fuel cost per KWh of electricity produced therefore multiplied by an electrical efficiency assumption of 34%, giving 13c/KWh
