(a) Costs may be expressed in $/GWe-yr by multiplying by 38,000 kg HM/GWe-yr.
(b) Reactor basin spent fuel storage costs are based on a charge of $6/kg HM
per year. The value shown in the table is equivalent to a minimum storage
time of 5 )ears with a real cost of money of 7% per year.
(c) Estimates based on facilities and operations described in ONWI-39,
July 1979, except that the cost calculations were modified to a 7% real
cost of money basis. Estimates include treatment of all wastes generated,
but do not include transportation and disposal. Costs for the entire system
are shown in Table 4.9.7.
(d) Average fuel cycle cost based on interim storage of 25% of total spent
fuel discharges.
(e) Packaging may be done at the repository or at another site. The transportation
costs for the example case are based on a packaging facility which
is integral with the repository and assumes that packaged fuel handling
is accomplished using repository facilities. Transportation costs consist
of $5/kg HM for shipment of 25% of the spent fuel to AFR storage,
$20/kg HM for shipment of the other 75% of the spent fuel from reactor
basins to final disposal and $6/kg HM for shipment of the fuel in AFR
storage to final disposal.
4.9.3.2 Reprocessing Fuel Cycle
Reprocessing fuel cycle wastes consist of wastes from reprocessing and mixed oxide
fuel fabrication plants. Table 4.9.4 shows the unit costs for alternative methods of waste
treatment for these wastes.
Differences in cost between treatment options are not large, ranging from 10 to 25%,
except for krypton removal. Predisposal costs for the example system are fairly evenly dis-
tributed between high-level waste treatment ($23.9/kg HM), TRU waste treatment
($18.40/kg HM), gaseous waste treatment ($28.20/kg HM), interim storage of high-level and
TRU wastes ($23.10/kg HM) and transportation ($15.50/kg HM). These costs total about
