Nuclear Power Economics | Nuclear Energy Costs - World ...

Effect of uranium price on fuel cost. Doubling the uranium price (say from $25 to $50 per lb U 3 O 8) takes the fuel cost up from 0.50 to 0.62 US c/kWh, an increase of one quarter, and the expected cost of generation of the best US plants from 1.3 c/kWh to 1.42 c/kWh (an increase of almost 10%). So while there is some impact, it is minor ...
