The fuel fabrication costs for <strong>the</strong> various reactor types are shown in Table B-5 as a<br />

function of time beginning with <strong>the</strong> expected introduction date for a particular reactor and<br />

fuel design. If a particular reactor and fuel design should prove successful, fabrication<br />

costs should decrease as larger plants with higher throughput rates are constructed. The<br />

decrease in fabrication costs over <strong>the</strong> first decade after introduction is simply indicative<br />

of a transition from small fabrication plants with high unit costs to larger fabrication<br />

plants with lower unit costs. These costs are a strong function of <strong>the</strong> fissile isotope and<br />

a weak function of <strong>the</strong> fertile isotope.<br />

The sensitivity to <strong>the</strong> fissile isotope is caused<br />

ei<strong>the</strong>r by <strong>the</strong> spontaneous fission associated with high-exposure fissile plutonium or by <strong>the</strong><br />

gamma activity associated with high-exposure 233U. The costs are based on <strong>the</strong> assumption<br />

that fuels containing 23% are fabricated on a line with contact operation and contact<br />

maintenance, fuels containing fissile plutonium are fabricated on a line with remote<br />

operation and contact maintenance, and fuels containing 233() are fabricated on a line with<br />

both remote operation and remote maintenance. The expected variations in fuel fabrication<br />

costs (cost uncertainties given in footnote b of Table 8-5) represent <strong>the</strong> upper and lower<br />

cost boundaries anticipated for fabrication costs and are expressed as percentages. For<br />

example, <strong>the</strong> expected fabrication cost for plutonium-bearing LWR fuel with uncertainties<br />

applied ranges from $306 per kg HM (-10% of reference) to $510 per kg HM (+50% of reference)<br />

for year 2001 and beyond.<br />

The expected reprocessing costs are<br />

shown in Table 8-6. These costs were obtained<br />

by estimating <strong>the</strong> capital and operating costs<br />

associated with each of five stages of <strong>the</strong><br />

reprocessing process. The stages were:<br />

headend, solvent extraction, product conver-<br />

sion, off-gas treatment, and waste treatment.<br />

The costs are shown as a function of time<br />

reflecting <strong>the</strong> transition from a new industry<br />

consisting of small plants with high unit<br />

costs to a mature industry consisting of<br />

larger plants with lower unit costs. The<br />

expected costs for spent fuel shipping, waste<br />

shipping, and waste storage are also included<br />

in Table 8-6, as well as <strong>the</strong> total costs for<br />

all <strong>the</strong>se processes. The tptal cost uncer-<br />

tainty factor for all fuel types is estimated<br />

to be a 50% increase for <strong>the</strong> reference values.<br />

Thus, <strong>the</strong> total reprocessing cost for LWR fuel<br />

with <strong>the</strong> uncertainty included ranges from $220<br />

to $330 per kg HM for year 2001 and beyond.<br />

It should be noted that it is assumed here<br />

that a policy decision will have been made in<br />

time for <strong>the</strong> first reprocessing plant to be<br />

in operation by 1991. All fuel discharged<br />

from <strong>the</strong> reactor prior to this date is<br />
