is deployed, the tails composition would decrease continuously from 0.0020 to 0.0010 between
the years 1980 and 2000 as the installed capacity of the advanced technology increased, and
the cost of a unit of separative work would decrease to approximately 60% of that of the
gaseous diffusion process. It was also assumed that the tails composition would further
decrease from 0.0010 to 0.0005 between the years 2001 and 2030 due to improvements in
technology, while the cost of a unit of enrichment would remain constant during this period.
The tails composition and enrichment cost were assumed to remain constant thereafter.
The capacity factors of a plant throughout its 30-yr lifetime are shown in Table B-9.
The capacity factor increases from 60% to 72% during the first 3 yr of operation and remains
at 72% during the subsequent 14 yr. It then decreases continuously as the forced outage
rate increases and as the plant is shifted from a base-load unit to an intermediate-load unit.
The long-term real cost of money to the electric utility industry is shown in Table 6-10.
These costs were developed by analyzing the deflated cost of debt and equity to the industry
over the past 30 yr. The long-term deflated cost of debt has been 2.5%/yr and the long-term
deflated cost of equity has been 7.0%/yr.
Assuming the industry to be funded at approximately
55% debt and 45% equity, the long-term real money cost is approximately 4.5%/yr.
The combined effects of capital , fuel fabrication, and reprocessing (or permanent
disposal) cost uncertainties on the levelized total power costs for individual reactor and
fuel cycle options are shown in Fig. B-1. These costs represent typical nonfuel components
whose uncertainties are easily quantified. Figures 6-2a and B-2b show the relationship of
total power costs to the U& price for four reactors on the throwaway fuel cycle.
sensitivity of the total power costs to the U308 price was analyzed first by assuming that
the price remained constant over the 30-yr life of the reactor, and second by assuming that
the price increases in relation to the rate of consumption (see Fig. 8-3). Thus, the total
power costs in Fig. B-2b are given for a reactor starting up with the U308 price shown on
