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 />
