The philosophy used in this study is<br />
illustrated in Fig. 6.0-1. Given a specified<br />
U308 supply and a specified set of reactor<br />
development options, <strong>the</strong> potential role of<br />
nuclear power, <strong>the</strong> resources required to<br />
achieve this role, and <strong>the</strong> composition and<br />
aEk<br />
movement of fissile material were calculated.<br />

duction date for each individual reactor con-<br />
cept and fuel cycle facility was assumed to be<br />
<strong>the</strong> earliest technologically feasible date.<br />
This allows an evaluation of <strong>the</strong> maximum im-<br />
pact of <strong>the</strong> system on any particular nuclear<br />
option.<br />
The effect of delaying <strong>the</strong> deployment<br />
of a reactor/cycle because it produces undesirable consequences was determined simply by<br />
eliminating it from <strong>the</strong> option.<br />
It was assumed that a nuclear power system was adequate if its installed nuclear capacity<br />
was 350 GWe in <strong>the</strong> year 2000 and a net increase of 15 GWe/yr was realized each year <strong>the</strong>reafter,<br />
with <strong>the</strong> increase sustained by <strong>the</strong> U308 supply.<br />
used in <strong>the</strong> study. A few runs were made assuming economic competition between nuclear<br />
fuel and coal, <strong>the</strong> plants being selected to minimize <strong>the</strong> levelized cost of power over<br />
time. These runs, described in Appendix D, indicated that for <strong>the</strong> assumptions used in<br />
this analysis nuclear power did not compete well at U3O8 prices above $160/lb; <strong>the</strong>refore,<br />
in <strong>the</strong> remaining runs an attempt was made to satisfy <strong>the</strong> demand for nuclear power with<br />
U308 available for less than $160/lb U308.<br />

The specific assumptions regarding <strong>the</strong> U3O8 supply are presented in Section 6.1 below,<br />
which also includes descriptions of <strong>the</strong> operating characteristics of <strong>the</strong> individual reactors<br />
utilized, <strong>the</strong> various nuclear policy options chosen for analyses, and <strong>the</strong> analytical method<br />
applied. Section 6.2 <strong>the</strong>n compares <strong>the</strong> results obtained for a selected set of nuclear policy<br />
options, and Section 6.3 summarizes <strong>the</strong> conclusions reached on <strong>the</strong> basis of those comparisons.<br />
The economic data base used for <strong>the</strong>se studies is given in Appendix By and detailed results<br />
for all <strong>the</strong> nuclear policy options are presented in Appendix C.
