FIGURE 7.3.11. Age of High-Level Waste Entering Repository for Case 3
with the Reprocessing Cycle
7.3.5 Facility Requirements
To estimate resource requirements, it is first necessary to define the number of waste
management facilities required in each case. In the once-through cycle, the only facilities
required in addition to the repository and packaging facility are the independent fuel stor-
age facilities for interim storage of the spent fuel. The number of these facilities
required is proportional to the maximum spent fuel storage requirements shown in
Table 7.3.2; a separate facility requirement table is not shown here. A 3,000 MTHM inde-
pendent spent-fuel storage basin model was used in this Statement as a basis for resource
requirement estimates. However, it is believed that facilities ranging up to 20,000 MTHM
capacity might be used in cases where the interim storage requirements are very large. (Sto-
rage facilities up to 18,000 MTHM are considered in the U.S. Spent Fuel Policy Statement
(DOE/EIS-0015 1980). The resource requirements and costs would decline somewhat as individ-
ual facility sizes increase because of scaling-effect efficiencies but radiation total
releases would not be affected.
For the. reprocessing cycle, the spent-fuel storage facility requirements would be pro-
portional to the maximum storage requirement shown in Table 7.3.3. Other waste management
facility requirements would be proportional to the number of fuel reprocessing plants and
MOX fuel-fabrication plants utilized to process and recycle the spent fuel. Requirements
for these facilities are shown in Table 7.3.9.
