Fig. B-1. Sensitivity of Total Levelized Power Cost to Capital, Fabrication, and
Reprocessing Cost Uncertainties.
the abscissa. The major difference between the two methods of analysis is the u308 price at
Which reactor options incur the same total power cost. For example, whereas at a constant
U& price the PWR and HWR options have the same power generation cost at * $160/lb U308
for an increasing UJO~ price they have the same cost at * $130/lb U&.
From the data shown in Fig. B-1 it is clear that the total power cost for each reactor
and fuel cycle option is dominated by uncertainties. The uncertainty effect produces a
significant overlap between reactor power costs. In addition, it is evident from Fig. B-2
that fuel costs, viz., U308 prices, also significantly affect not only the levelized power
costs but also the competitive relationship between reactor options. Therefore, it is
difficult to classify reactors as either more economical or less economical based solely on
power generation cost estimates.
