The economic data base used in .the assessment of the impact of denatured fuel cycles in
the various nuclear systems options described in Chapter 6 was jointly developed by Combustion
Engineering, Oak Ridge National Laboratory, United Engineers and Constructors, Argonne
National Laboratory, Resource Planning Associates, Hanford Engineering Development Laboratory,
DOE Division of Uranium Resources and Enrichment, and DOE Division of Nuclear Research and
Applications. The data base includes capital costs, operation and maintenance costs, fuel
fabrication and reprocessing costs, capacity factors, money costs, and uncertainties.
The deflated and present-valued capital costs for LWRs, SSCRs. HTGRs, CANDUs, and FBRs,
excluding interest during construction, are shown in Table B-1.
including interest during construction are shown in Table B-2.
The same capital costs
In either case, the stream of
expenses incurred during the construction of the plant is discounted to the date of startup
and is measured in dollars of constant purchasing power. The uncertainty ranges included in
Table 8-2 represent current best estimates of the most probable variations in capital costs.
For flexibility, the uncertainties are expressed relative to the reference LWR capital cost.
Table B-1. Capital Costs of Power Plants
Excluding Interest During Construction
The operation and maintenance costs
for the same power plants are shown in
Power Plant Type Costs ($/kWe)* Table 6-3. The higher costs for the SSCR
and the CANDU over the standard LWR are due
LWR 500 to the heavy water replacement requirement
SSCR 520 + 39 (for D20) = 558
and the necessity for performing some
