'Fabrication costs based on <strong>the</strong> following: for LWR<br />

and SSCR, a 17 x 17 pin assembly (374-mil-OD pin);<br />

for <strong>the</strong> HWR, a 37-pin CANDU assembly -20 in. long<br />

(531-mil-OD pin); for <strong>the</strong> HTGR, standard carboncoated<br />

uranium carbide fissile microspheres formed<br />

into cylindrical rods located in a hexagonal graphite<br />

block; and for <strong>the</strong> FBR, a 217-pin assembly<br />

in a hexagonal duct (310-mil-00 pin).<br />

bUncertainities on fabrication costs: 235U-bearing<br />

fuels, no uncertainty; Pu-bearing fuels, -10% to<br />

50% increase; 233U-bearing fuels, -10% to 50%<br />

increase.<br />

CCosts assumed to remain constant.<br />

assumed to have been stored, with <strong>the</strong><br />

spent fuel stockpile being reduced in an<br />

orderly manner after <strong>the</strong> advent of reprocessing.<br />

After <strong>the</strong> spent fuel stockpile<br />

has been reduced to zero, <strong>the</strong> out-of-reactor<br />

time required for reprocessing and refabrication<br />

is assumed to be two years.<br />

The long-run marginal costs estimated<br />

for U308 ore as a function of <strong>the</strong> cumulative<br />

supply are shown in Table B-7. As noted in<br />

Chapter 6, <strong>the</strong> U308 estimates have been<br />

provided by DOE'S Division of Uranium<br />

Resources and Enrichment (URE), <strong>the</strong> highcost<br />

supply being based on <strong>the</strong> assumption<br />

that approximately 2.5 million tons of U308<br />

will be available from conventional uranium<br />

ore resources and <strong>the</strong> intermediate-cost<br />

supply being based on <strong>the</strong> assumption that<br />

approximately 4.5 million tons of U308<br />

will be available. In ei<strong>the</strong>r case, it is<br />

assumed that shales can be mined after <strong>the</strong><br />

conventional resources are depleted. The<br />

cost of extracting <strong>the</strong> shales increases<br />

from $125/lb to $240/lb for <strong>the</strong> high-cost<br />

supply case and from $100/lb to $180/lb<br />

for <strong>the</strong> intermediate-cost supply case. It<br />

is important to note that <strong>the</strong> long-run<br />

marginal costs shown in Table B-7 are larger<br />

than <strong>the</strong> forward costs shown in Table 6.1-1<br />

of Chapter 6 because <strong>the</strong> long-run marginal<br />

costs contain <strong>the</strong> capital cost of facilities<br />

currently in operation, plus a normal profit<br />

for <strong>the</strong> industry. The long-run marginal<br />

costs are more appropriate for use in a<br />

nuclear strategy analysis.<br />

The enrichment costs and tails<br />

compositions assuming e5 <strong>the</strong>r a continuation<br />

of <strong>the</strong> gaseous diffusion technology or <strong>the</strong><br />

deployment of an advanced enrichment technology<br />

are shown in Table 8-8. It was<br />

assumed that if <strong>the</strong> gaseous diffusion<br />

technology is continued <strong>the</strong> tails composition<br />

will be stabilized at 0.0020 and that<br />

<strong>the</strong> cost of enrichment will increase to<br />

$80/SWU in 1987 and remain constant <strong>the</strong>reafter.<br />

If an advanced enrichment technology
